I have two on my roof for 9 years with no problem at all. Never seen any water leak or heard any noise. It actually helps in the summer when it is 90+ degree outside. I never notice any higher heating bills in the winter either so for me it works great.
@@allenlivera1611 I'll gladly tell you where I am, dude. I live in the relentless swamp heat gulf area with 102° heat index. And that's OUTSIDE, dude. The likes of you, and your clumsy "A/C" techs" couldn't take it up in my attic. If you could breathe. Count on it. Not only that, even I have to bend over around the air handling system, as I tippy toe in top of the boards in my attic. I wouldn't trust any of your clunking fat boy contractors in my attic. The point is, dude, this rotating vane roof vent is a MUST HAVE where I live. Period.
had the same one on my roof here in Indiana for over 30 years and still going strong. These are the best ventilation method you can get. It is far superior to any other type especially ridge vent.
GO WHIRLYBIRDS!!!!!! YOU ARE absolutely right!!!!! My neighbors have had theirs on their roof for 30 plus years. have had to replace 2 roofs in twenty years due to the heat in souther NH.....I recently put a WHIRLYBIRD from LOMANCO on my roof. I am a WOMAN and did it myself. lol, it took me 4 hours because I had to carry the stuff up and down and was back and forth on the ladder to the attic and back again to be sure I was putting the hole in the roof where it needed to be, however, I did it and its awesome and my house has cooled down already.
I picked up 3 wind turbines at Home Depot and installed them, when I put my roof on in 1994. I never needed to oil them. No leaks! No rain has ever gotten inside of them. They are still spinning efficiently after 30 years!! Never stops spinning and no noise ever!
Hi Johnny, in my experience the bearings on Aussie Whirly birds often only go after very extreme weather events like Cyclones where additional extreme forces are applied, this happened to ours after about 42 years of service on our older house. Yours should get a fair few more years of service. They were cheap to replace and install. Here where I live in northern Australia we generally don't get the lower temps in winter that would bother us enough to get up on the roof to put covers on the whirly birds to retain extra heat in winter, we don't use heating most of the time, even with the whirly birds still operating through the winter, we maybe will only get a handful of nights that get below 10'C each year & we have a wood stove fireplace and electric blankets for those kinds of nights which are a bit of a novelty to actually get the fire going, this year I only used two hessian bags of hardwood in my stove, it doesn't really warm the place up much but it was nice to warm yourself in front of, the cat likes laying in front of it, traditionally we just go to bed earlier in winter and use the electric blankets instead of heating up the whole house in our culture. Do u cover ur whirly birds in winter to retain heat?
@@alisonaussie4995 Hi Alison, Yes, every year, I’d make it a habit of covering my wind turbines during winter so as to not lose heat. None of the other neighbors cover theirs though. There are different manufacturers of wind turbines. I guess I got lucky with mine. I never had to oil mine, nor have they ever slowed down or stopped working. Never any noises either. Btw, I live in LA., Cali.
lol i agree with you.....every roofer hates to put up Whirlybirds because they extend the life of the roof.....I had to replace my roof 2 times in 20 years because the hip roof I have didn't have enough air flow in the soffits thereby keeping my attic area extremely hot. Finally, I decided to do it myself. I am a woman and I used a 9 inch Lomanco Whirlybird and my house is cooler and now I have hopefully saved myself from having to do another roof. My neighbors in Southern New Hampshire have had theirs on their roofs for 30 years. One of them has lived here since she was 20 years old. They just did her roof and they put the WHIRLYBIRD back up. It's been there for 30 plus years and still working. ROOFERS HATE WHIRLYBIRDS because they know you will need a new roof more often without them. If I can do it anyone can!!!!!!!!!!
As a Contractor no doubt you have a better more costly solution. I've lived in several homes in Florida, Texas and the North. I've been through several hurricanes with them and the one single thing I have never seen (when they are operating correctly) is water penetration into the ceiling area. If it did these would have become unsellable decades ago. However your point about them in the winter here in Texas is very valid. That's why they make covers for these that you can use during the cold months. Sure there are other solutions but I guarantee they cost more and are less reliable and may have the same caveats.
I installed three Lomanco whirlybirds on my roof 42 years ago. Canadian summers and winters are brutal. The vents have nothing to do with sucking heat out of your house. If they did, then the house was built wrong and very poorly insulated. They are just starting to show signs of wear. Lomanco replaced them for free under their lifetime warranty. Those don't look like they're made by Lomanco. Are they knockoffs? Try Lomanco. You won't be sorry, no matter where you live. Texas is no exception. Thanks for the video, Gary!
Whirly bird vents work better towards the peak and if you have soffit vents to help draw the heat out. If you do not have soffit vents, your whirly bird will not be as effective, it will just be an escape hole for heat to go through, but will not create a drawing out of air.
If you buy the cheap galvanized ones they will start squeaking and not turning if you get the good aluminum ones by lomanco with permanently lubricated ball bearings, they will last for years it is a great form of ventilation
Lomanco does make the Galvanized and they are much heavier duty than the aluminum, where the aluminum can bend much easier. Both are lifetime warranty.
The turbine just needs a squirt of canned silicone to stop it squeaking and make it run smooth again. That's an easy fix. I do think there should be a brake on it which can make it not turn in the colder months though.
Thank Gary, Depending on placement and attic design it is much easier to grease these from inside the attic. I luv em, they are super easy and cheap to replace, even a novice DIYer can do for pennies on the dollar.
If I was roofer, I would also hate turbines, since heat cooks shingles, requiring more roof jobs. Mine are 40 years old, still work perfect and no rain inside our very rainy environment.
Interesting comment. If you had done your research, you would know we actually work very hard to be sure people vent their attics or insulate well. Before you judge so quickly next time do a little homework first. Here are some videos for you to check out, get to know us before judging us. A roof just completed; ruclips.net/video/S2MvVmQLX7s/видео.html A roof from four years ago; ruclips.net/video/nxd7vCh7lZg/видео.html Thanks for the opportunity to post these videos in the comment section.
In West Texas, the wind blows all the time. After having turtle vents put on with a new roof, we went back to turbine. The turtles don't vent well enough in the summer. We had three turbines before, then the roofers installed 9 turtles. Our house got much hotter indoors and put a lot of load on the air conditioner. It just couldn't keep up. We replaced 5 of the turtles with wind turbine and the problem went away. But we always cover our turbines in the winter to prevent heat loss.
Thank you for your comment. A good point, every part of the country is different, west Texas is very unique. We found there are several things different needed in that area!
I bought my house with turbines on the roof, my home was about 13 years old, one of two started squealing about 20 years laters, so I replaced it. If this turbine was on my home since it was built, it was possibly 33 years, not bad at all. I bought a replacement because if I can get another 30 years out of it, it's well worth the money.
Winter time I use turbine covers, keeps heat. Definitely saved my AC from running all the time once I installed 3 on my roof (Phoenix) Keeps roof cooler and helps with shingles not getting cooked to
My wind turbines failed after 10-15 years. They could have gone longer, but the PLASTIC-caged bearings failed. After trying to buy just the bearings and being told I would have to buy the whole thing, I used some sealed steel bearings I had in a box of misc parts. Had to drill out some rivets and put in screws - I guess the guy at the building supply store didn't think that was a "thing." Plastic bearings... Sheesh!
Gary, Thanks for the video. I first became familiar with turbine vents when my family relocated to Texas, and have since used them to cool garage attics and sheds, where winter heat loss (none) is not an issue. I hadn't thought about wind-driven rain until I watched this video. My current garage turbine failed: the bearing partially failed and scored the spindle, which snapped. I heard the warning noises last winter, but I don't climb on roofs in Michigan winters. I temporarily capped it and ordered a replacement from Lowes. This time I got one with external bracing. Thanks again for sharing your knowledge
I’ve had mine for 3 years now in Cape Town, extreme wind, rain and heat. Still works great, significantly cooled my upstairs. And it’s called a turbine not a turbin. You get what you pay for.
@@owwkaey1181 Heat rises. So, therefore, since there are vents on the wind turbine, the heat escapes through those vents and outside of your home and through the outside air and atmosphere.
Spend the money and get the lomanco or equivalent with ball bearings. Also, place it near the top of the roof and make sure there are lots of eave vents to feed it and not suck heat from the house, that would suck. Also, the rotation plane should be level to the ground not the roof, use a level. these work for hip roofs that do not have sufficient ridge vent length.
Notice how close that turbine vent is located to the turtle vent. I bet one of those vents has short circuited and has become an intake. Also, it is not a good idea to mix static with passive vents.
In winter you dont want your attic to be warm. That causes icecicles and worse, ice dams which can pour water onto the ceil of your home and major damages to furnishes, electronics, etc. A cool attic is good for your home year round.
In Florida these things are definitely not recommended although many roofers still use them. During hurricanes these turbines disintegrate. Best option is gooseneck static vents.
The four wind turbines on my house in the Southern California desert are driving me crazy. The squealing is absolutely maddening. I've taken the whole thing apart and oiled it, which worked for a while. Now the screaming sound is back. I climbed up there yesterday and emptied half a can of silicone into it, waited, checked it, put in more...finally it worked...and now it is squealing again. Though I live in a desert with highs into the mid 120s, I would give anything to stop the darn things from spinning, of those that still spin at all. A year ago, my son went up and covered the worst one, but that covering has come off. I am in my late sixties, disabled and dealing with cancer. I just wish I could shoot the darn thing to shut it up. Is there nothing on the market beside black plastic covers (which disintegrate within months in our high winds) to stop the darn things from turning at all? A DIY tip? I just can't deal with this anymore. I wish wish wish I had the awesome roof fan I had when I first bought the place in 2004. That made a huge difference in the heat in the house in summer. Now I can't afford another one (it was replaced when I reroofed and put solar panels up there, that first year). And as a physically challenged person, with a tilted roof it is very hard for me to keep getting up there to try to stop the screeching sound. Any advice welcome. Thanks.
Had 3 of them on parents house we sold. The did not squeak and spun easy. They were really big and put on in the 1970's, so big they had a huge elbow able to run them straight. House also had a broke attic gable fan which I replaced. We put on a new roof for the sale and I told the roof contractor to get rid of them. Only downside besides the look was during hurricane Isabel, they let water into the attic which ruined the ceiling, water stains and wallboard tape came loose. Had roofer put on a ridge vent, ad kept the attic fan and gable end vents. Attic seemed to cool fine. When they were on the ground, I was shocked at how big they were. All 3 were in good shape and could have been reused. Only real reason I got rid of them was hurricane water damage caused by them.
I live in the northwest and we get lots of rain. I have a piece of plastic in the attic below the turbines and I have never seen water on them. My whirlybirds are mounted near the ridge and I made sure they were installed level. If your turbine is making noise or not spinning, lubricate or replace the bearings. Most manufacturers have a lifetime warranty.
I have had the wind turbines last 40+ years and used them in both upstate New York and Mesa Arizona. Never had rain, snow or hail come through into the building. In the winter they pull moisture from the attic space, while during the summer pull heat. So you can use static heat flow, power fan flow or wind turbine flow, the wind it free and uses no electric. I prefer them to all other ventilation types.
Same here, using them in Phoenix, Az with Lomanco perm ball bearing model. They are the best for active attic ventaltion!! That plastic ridge vent crap doesn't last here in the brutal AZ heat!
To begin with, in order for whirlybird turbines to work they need to be placed near the ridge of your roof where you can see the tops from the front of your home or they cannot catch the wind.
Product design does make a difference. Lomanco Whirlybird® turbine vents are Miami-Dade Certified and do not leak.They are also guaranteed forever. You can not beat that! Like any home ventilation system the Turbine is an exhaust vent and must be properly balanced with proper intake. If you install a quality product like the Lomanco Whirlybird® as your exhaust of a properly balanced ventilation system it is no better or worst than any other quality exhaust vent. The problem you have is with using an inferior turbine vent or an improper ventilation system.
SelectShots SelectShots what about when there’s 3 feet of snow on the roof and the vent is frozen in place and leaking snow?? or how about the squeaking?? they leak all the time! people put buckets in their attic to catch the water from them ! horrible vents install the Air exchanger ventilation maximum! so much better. that’s a real vent.. your welcome
Did any one feel temperature is reduced after installed in closed the room?.. we are in India, very hot in summer and we having a closed room with single door only.. so i planning to install this turbine.. Kindly share your feedback..
of course, then the next professional says completely opposite. I says exactly what is a myth about these turbine vents. Even in winter you some warm air to get sucked out and circulate the air or you can get condensation as well.
They work. You are right on them pulling heat though. Although I don't think you need as much as they recommend. My house was born with one from the 50s. It had newspaper insulation and never saw water. Is under half the recommended amount installed.
What is better then a Turbine? All I have is one static vent and my attic is 150 degrees. I'm trying to figure out how to get some ventilation up there.
No proof as to what you are saying Gary. If it's installed correctly for balance and weather proofing, they work. Nothing lasts forever, but these do last a long time. I suggest the galvanized over the aluminum, much heavier duty.
The empirical evidence obtained, backed by hundreds of photos - show what I am talking about. There is, in the areas of the country where I have worked, overwhelming evidence of leaves below the whirlybird vents, and insulation damage along with drywall ceilings with water stains. This is my conclusion after being involved with thousands of roofs. Others who have more data, could prove me wrong, that has yet to be done. However, the other side of the coin is, from your perspective, the roofs you have seen, you are probably right in those circumstances. Either way, your opinion is appreciated, and I respect your findings. Thanks for your comment.
LOMANCO sells whirlybirds that are guaranteed to be oiled forever. I just put one up, (i'm a woman) .....my neighbor has had one for 30 years and in the 40 years she has owned her home she only replaced her roof once. It was just replaced this month and they put the same old WHIRLYBIRD back up ....
I have an indoor pool. Replacing the roof (leaking, poor previous install). Never insulated before. Planned to be lined with sisalation/sarking. No insulation as concern about moisture/fungus. Considered 2x whirlybird for better ventilation for pool/water moisture, bit now hearing how loud they are is putting me off- even more reading what youve written. Are vents worth it in my situation, & if so, solar vents? Any opinions
I've had mine on my roof for over 20 years with no problems. Northern climate. They don't get covered up with snow like ridge vents or the flat plastic or metal ones. Never have leaked like the flat plastic ones that were on there. They leaked from day 1.
You know they have covers for a turbine vent right… might set ya back about $12.00 each if you can afford it, I’d buy them and put the covers on in the winter time. That’s what we do here in Arizona… maybe they do things a little differently in Texas however.
Gary can you please advise me on what is better than Turbines? I live in Los Angeles, CA and summer time my attic retains heat. The attic has side vents rectangle shape 16 X 6, but I don't have top roof vents, which I think will really help. The house was built in 1948.
Use Lomaco brand turbines and they'll never squeak. Cheap turbines will squeak. I've never seen a quality turbine leak in the heaviest of rain....ever.. You're not supposed to hold heat in the attic during the winter. You're asking for condensation problems in Texas.
I have a turbine with one of the pieces flapping loose as it turns. Do I have that secured with a rivet? I'm sure the turbine doesn't need oiling...it's just that one of the pieces is flapping in the wind.
Thanks for watching my video, Wind Turbins are easy to replace, there are other options for venting also, simply find someone in your area who knows about venting a roof. Best to you! GW
My home has a wind turbine mounted near a bathroom that is on the septic tank line. It is 12 years old and all is well! Have another bath room further away with alike set up, 2 to 3 years is long as a wind turbine will last! They are a necessity here. Have one on a metal storage barn removing heat constantly. Been there for a long time and does a fair job venting hot air. No rain has ever came in through this turbine! None of these turbines are ever oiled! West Texas! Some time wind turbines can be helpful, useful and sometimes they become a pain as they can deteriorate rapidly and that means money!
Thanks Gary, quick question. I have the same turbine here in Canada, Ontario, and the top of the axle cap broke and the turbine cannot be kept in the centre and rotate. Everything else seems ok. Would you be able know where I could find this top cap spare part, please?
My house has two electric exhaust blowers, one for each attic. The blowers are temperature controlled and will only kick on automatically when the attic gets hot. These blowers definitely save on our electric bill since it is able to evacuate all the hot air that can make its way into the house. Cooling a 5,200 sq. ft. House with three compressors ain't cheap! During the winter, it obviously won't kick on and the flapper on the fan shuts when the blower is off. The blowers are 1/4 HP and don't consume that much power since I wired them to use 240v. If anything, they probably add $5-10 to the bill every month. The only issue is that they have to connect to power and they do make noise that isn't loud or annoying, just noticeable. Using 120v would increase the power consumption but they really only run intermittently so it's not a big deal. My grandfather has the spinning turbines on their house being an older home and they haven't had too many problems with them. Every once in a while they need to be oiled but that's it. We did have to replace the bearings in on of them but those turbines are over 45 years old on the original bearings. They work ok for him, but they don't full out the heat as fast as he wanted.
Power is measured in watts. If wired 240 or 120 you might use half your amperage but your wattage is the same so the power used would be very similar watts = voltage*amperage. Say it's 120v * 10 amps = 1200w but at 240 it would be 240v* 5 amps =1200w .
I had to remove the electric exhaust blowers on my house in Florida and replace them with passive gooseneck vents. The problem was the electric exhausts were sucking all the AC out of the house mostly through the 52 can lights on the ceilings. After replacement my electric bill went down 20% during summer just from the AC savings alone and attic temperatures increased by no more than 5 degrees. This was detected during a power utility energy audit and I thought the trade off made perfect sense.
Since when would you not want your attic temperature to be same as the ambient temperature? This guy is complaining about heat being sucked out of the attic in January? The last thing one would want is HEAT above the surface of the insulation (in the attic space).
My neighbor has one that squeeks and the sound is VERY loud and is driving me and some of the other neighbors crazy. It's just as bad as the sound of fingernails across a chalk board, except louder. Isn't there a silent alternative????
Thanks for your question, every house is different. Currently, one house we are doing, we have added baffles in the attic to contain the insulation, then cut in soffit vents, 2-1/4" of venting for 170 feet around the eaves, vents are perferated vents to keep bugs out. Then we did a ridge vent on all ridges, (a gable roof, multiple gables), allowing the air to just flow. Here is a link on another way we did one, maybe it will help give you ideas. ruclips.net/video/nxd7vCh7lZg/видео.html Best of luck. GW
I think these turbine vents are really ugly even when they work properly. Driving around in my neighborhood, I have seen at least 6 or 8 houses where it looks like their round turbine vent has become dislodged from its original installation and those round vents are just dangling sideways off of the vertical pipe. So just the metal tube sticks up from the roof and it looks like the round turbine vent is only being held onto the side of the tube by one or two screws or nails. We get wind gusts up to 60 or 70 MPH here every year, so perhaps the wind is blowing all these turbine vents off of their pipe tubes? How are these turbine vents becoming detached from their tubes in my neighborhood?? What happens to these homes' turbine vent tubes when their top turbine gets detached and just dangles on the side of the tube? Does that mean there is a big open space for rain and snow to fall straight into their attics?? A lot of these houses with their detached turbine vents have been like that for several years now. These are all two-story houses, so these homeowners cannot even see their damaged roof turbines from their front or back yard because you only notice the detached turbines if you look at these roofs from a distance away.
That kind of turbine ventilator, when working/maintained properly, does keep rain out. For example, Air-Vent's Turbine Ventilator, has a Miami-Dade Approval, which requires that it not only won't be damaged by high wind, but that it pass the standard test TAS-100(A) to prove that it keeps 99.95% of 110mph wind-driven rain out.
Many people use a simple 3/4" screw, drill a hole and install a screw to keep them from turning. The only problem is, they could leak in a hard blowing rain!!!! Best to have them removed. Best of luck and thanks for watching my videos! GW
This is in the south east. Temps to the low 90’s and 5 degrees with 8 to 10 inches of snow because of elevation in winter. There is aluminum perforated soffit but between the rafters it has blocking so I don’t know how that can vent thru that. Has four mushroom type vents in each roof section near the top ridge.
I would think an open vent ie pipe, mounted high, would suck more air out due to venturi effect, and w/o the lost energy and hindrance of the turbine . Though of course you'd need a way to keep the rain out.
Turbines are bogus. On a hot windless day, people see the turbine turning. They know that hot attic air expands, creating higher attic air pressure which escapes through the vent hole. If that hole has a turbine mounted on it the turbine rotates. But that rotation does not in turn pull more air out of the attic. Actually in this situation more air would escape if the turbine were not there blocking the hole area. Part of the energy of the escaping air is sacrificed in turning the blades resulting in less hot air escaping. On windy days It seems intuitive that the spinning blades act like a fan and draw air out of the attic space. No. Air is drawn out because wind blowing over the roof has less pressure than the inside the attic. If there is a hole in the attic, such as at the turbine, the air moves from high to lower pressure. The wind spinning the turbine does not create any lower pressure than a simple hole in the roof. Again, it is the opposite because the turbine blocks the wind over the hole and therefore raises the pressure at the hole. The delta inside/outside pressure at the hole is less with a turbine; therefore, less, not more air leaves the attic. Of course an attic vent hole can’t just be open to the elements, so do turbines block less air than a simple turtle cover. I don’t know. Just saying that turbines are not at all what most think they are.
Sooooooooo it takes 5 min to take it apart and grease it,as a home owner you should hire someone or yourself to step on your walkable roof at least once a year and inspect...dummy
The two top options are carefully selected Ridge Vent or Dormer Vents combined with Proper Intake vents. In the following video we added full perimeter intake vents with the Dormer Vents. ruclips.net/video/nxd7vCh7lZg/видео.html
fiapop I agree with Gary in that a " Passive " ventilation system will outperform an " active " vent system that uses wind powered Turbines ,or thermostat controlled electric fan vents , a passive vent system should consist of 1 standard can vent for every 4 squares of roofing ,so an average house of 20 square would require 5 standard can vents ,in order for the passive or active vent systems to work properly a roof attic will need the same number of sq ft sofit vents as roof vents at a minimum ,I prefer to use 20% more sofit vent space than required to make up for vents that can become blocked with dust or insulation ,as for using " ridge vent " systems you should never use any ridge vent system to replace or eliminate standard can vents ,as has become modern practice, in order for a ridge vent system to REPLACE can vents only 1 type of ridge vent can be used ,which is a metal ridge vent that installs directly over the peak after cutting out 2 inches of peak ,the metal ridge vent systems allow for a free flow of air ,the ridge vent systems where you roll out a thick fibered Matt, then install shingle cap over top ,or the plastic vents you lay over the peak and install shingle cap over the top do not offer the same unobstructed air flow as a metal ridge vent that does not require shingle cap installed over top . The only houses I ever install ridge vent is in areas of the home where there is vaulted or cathedral ceilings ,on all homes with 100% attic space I use 1 can vent for every 4 sq or 400 sq ft of roofing ,active vent systems like powered vents and Turbines do not offer a steady ventilation and can increase your heating & cooling costs . BTW my credentials are 35 years as a Foreman Journeyman Roofer & Waterproofer with roofers local #149 Detroit Michigan ,I attended 4 years of trade school to become a Journeyman Roofer as well as attending the courses in HVAC " ventilation " and roofing related plumbing & sheet metal required to become a Master journeyman ,the points Gary made were valid, items like turbines, powered vents and shingle over ridge vents are made to appeal to the homeowner ,not the professional roofer ,the roofing industry standard is still the time tested & proven passive vent systems Gary outlined.
A good question. Thanks for watching. Every house, every roof is different. Have an expert, (far and few between) help with this or do some good research to determine the best way. Here is an example, not for every house, just one example: ruclips.net/video/nxd7vCh7lZg/видео.html
I have two on my roof for 9 years with no problem at all. Never seen any water leak or heard any noise. It actually helps in the summer when it is 90+ degree outside. I never notice any higher heating bills in the winter either so for me it works great.

@@deborahk.6113
Thank you for your advise Home Depot has the brand and model you recommended in stock
They made them cheaper now thats why
I picked up 3 wind turbines at Home Depot and installed them, when I put my roof on in 1994. I never needed to oil them. No leaks! No rain has ever gotten inside of them. They are still spinning efficiently after 30 years!! Never stops spinning and no noise ever!
Hi Johnny, in my experience the bearings on Aussie Whirly birds often only go after very extreme weather events like Cyclones where additional extreme forces are applied, this happened to ours after about 42 years of service on our older house. Yours should get a fair few more years of service. They were cheap to replace and install. Here where I live in northern Australia we generally don't get the lower temps in winter that would bother us enough to get up on the roof to put covers on the whirly birds to retain extra heat in winter, we don't use heating most of the time, even with the whirly birds still operating through the winter, we maybe will only get a handful of nights that get below 10'C each year & we have a wood stove fireplace and electric blankets for those kinds of nights which are a bit of a novelty to actually get the fire going, this year I only used two hessian bags of hardwood in my stove, it doesn't really warm the place up much but it was nice to warm yourself in front of, the cat likes laying in front of it, traditionally we just go to bed earlier in winter and use the electric blankets instead of heating up the whole house in our culture. Do u cover ur whirly birds in winter to retain heat?
@@alisonaussie4995
Hi Alison,
Yes, every year, I’d make it a habit of covering my wind turbines during winter so as to not lose heat.
None of the other neighbors cover theirs though.
There are different manufacturers of wind turbines. I guess I got lucky with mine. I never had to oil mine, nor have they ever slowed down or stopped working. Never any noises either. Btw, I live in LA., Cali.
So you say they suck but offer no solution. immensely helpful.
lol i agree with you.....every roofer hates to put up Whirlybirds because they extend the life of the roof.....I had to replace my roof 2 times in 20 years because the hip roof I have didn't have enough air flow in the soffits thereby keeping my attic area extremely hot. Finally, I decided to do it myself. I am a woman and I used a 9 inch Lomanco Whirlybird and my house is cooler and now I have hopefully saved myself from having to do another roof.
My neighbors in Southern New Hampshire have had theirs on their roofs for 30 years. One of them has lived here since she was 20 years old. They just did her roof and they put the WHIRLYBIRD back up. It's been there for 30 plus years and still working. ROOFERS HATE WHIRLYBIRDS because they know you will need a new roof more often without them.
If I can do it anyone can!!!!!!!!!!
As a Contractor no doubt you have a better more costly solution. I've lived in several homes in Florida, Texas and the North. I've been through several hurricanes with them and the one single thing I have never seen (when they are operating correctly) is water penetration into the ceiling area. If it did these would have become unsellable decades ago. However your point about them in the winter here in Texas is very valid. That's why they make covers for these that you can use during the cold months. Sure there are other solutions but I guarantee they cost more and are less reliable and may have the same caveats.
@Gary, 2 fixes for those turbines.
1) WD-40
2) Wind Turbine Covers in Winter.
Bam! Done!
You must be the kind of guy who expects a car to run forever without changing oil..lol

I installed three Lomanco whirlybirds on my roof 42 years ago. Canadian summers and winters are brutal. The vents have nothing to do with sucking heat out of your house. If they did, then the house was built wrong and very poorly insulated.
They are just starting to show signs of wear. Lomanco replaced them for free under their lifetime warranty. Those don't look like they're made by Lomanco. Are they knockoffs? Try Lomanco. You won't be sorry, no matter where you live. Texas is no exception. Thanks for the video, Gary!
Whirly bird vents work better towards the peak and if you have soffit vents to help draw the heat out. If you do not have soffit vents, your whirly bird will not be as effective, it will just be an escape hole for heat to go through, but will not create a drawing out of air.
For my entire life as an autistic person I've always liked the turbines. That's why I have some on my house plus a collection of them.
Awsome!
That's awesome! I just bought two raw aluminum ones they are definitely satisfying to watch!
Nice! That's great!
You are just like me
If you buy the cheap galvanized ones they will start squeaking and not turning if you get the good aluminum ones by lomanco with permanently lubricated ball bearings, they will last for years it is a great form of ventilation
Lomanco does make the Galvanized and they are much heavier duty than the aluminum, where the aluminum can bend much easier. Both are lifetime warranty.
Lomancos are the best!!
Turbine roof
The turbine just needs a squirt of canned silicone to stop it squeaking and make it run smooth again. That's an easy fix. I do think there should be a brake on it which can make it not turn in the colder months though.
When the weather gets cold, I just put duck cloth covers on them.
Thank Gary, Depending on placement and attic design it is much easier to grease these from inside the attic. I luv em, they are super easy and cheap to replace, even a novice DIYer can do for pennies on the dollar.
If I was roofer, I would also hate turbines, since heat cooks shingles, requiring more roof jobs. Mine are 40 years old, still work perfect and no rain inside our very rainy environment.
Interesting comment. If you had done your research, you would know we actually work very hard to be sure people vent their attics or insulate well. Before you judge so quickly next time do a little homework first. Here are some videos for you to check out, get to know us before judging us. A roof just completed; ruclips.net/video/S2MvVmQLX7s/видео.html A roof from four years ago; ruclips.net/video/nxd7vCh7lZg/видео.html Thanks for the opportunity to post these videos in the comment section.
In West Texas, the wind blows all the time. After having turtle vents put on with a new roof, we went back to turbine. The turtles don't vent well enough in the summer. We had three turbines before, then the roofers installed 9 turtles. Our house got much hotter indoors and put a lot of load on the air conditioner. It just couldn't keep up. We replaced 5 of the turtles with wind turbine and the problem went away. But we always cover our turbines in the winter to prevent heat loss.
Thank you for your comment. A good point, every part of the country is different, west Texas is very unique. We found there are several things different needed in that area!
You dont need to cover the vents in winter. Causes moister build up...black mold. Roof should be vented...intake...outake all year round
@@darrenmcintosh326 i agree
I bought my house with turbines on the roof, my home was about 13 years old, one of two started squealing about 20 years laters, so I replaced it. If this turbine was on my home since it was built, it was possibly 33 years, not bad at all. I bought a replacement because if I can get another 30 years out of it, it's well worth the money.
Winter time I use turbine covers, keeps heat. Definitely saved my AC from running all the time once I installed 3 on my roof (Phoenix) Keeps roof cooler and helps with shingles not getting cooked to
My wind turbines failed after 10-15 years. They could have gone longer, but the PLASTIC-caged bearings failed. After trying to buy just the bearings and being told I would have to buy the whole thing, I used some sealed steel bearings I had in a box of misc parts. Had to drill out some rivets and put in screws - I guess the guy at the building supply store didn't think that was a "thing."
Plastic bearings... Sheesh!
Gary, Thanks for the video. I first became familiar with turbine vents when my family relocated to Texas, and have since used them to cool garage attics and sheds, where winter heat loss (none) is not an issue. I hadn't thought about wind-driven rain until I watched this video. My current garage turbine failed: the bearing partially failed and scored the spindle, which snapped. I heard the warning noises last winter, but I don't climb on roofs in Michigan winters. I temporarily capped it and ordered a replacement from Lowes. This time I got one with external bracing. Thanks again for sharing your knowledge
I’ve had mine for 3 years now in Cape Town, extreme wind, rain and heat. Still works great, significantly cooled my upstairs. And it’s called a turbine not a turbin. You get what you pay for.
What happen during hot, no wind and it didn't spinning? Because wind doesn't blow all the time. Is it hot inside?
@@owwkaey1181 Heat rises. So, therefore, since there are vents on the wind turbine, the heat escapes through those vents and outside of your home and through the outside air and atmosphere.
Spend the money and get the lomanco or equivalent with ball bearings. Also, place it near the top of the roof and make sure there are lots of eave vents to feed it and not suck heat from the house, that would suck. Also, the rotation plane should be level to the ground not the roof, use a level. these work for hip roofs that do not have sufficient ridge vent length.
Thanks for you input!
You are correct about placement, my neighbor has some and they are placed so low on the roof, on the wind protected side, that they never spin.
Notice how close that turbine vent is located to the turtle vent. I bet one of those vents has short circuited and has become an intake. Also, it is not a good idea to mix static with passive vents.
Just put some axel greese on those bad boys and good as new
Maybe silicon grease? Less melting.
In winter you dont want your attic to be warm. That causes icecicles and worse, ice dams which can pour water onto the ceil of your home and major damages to furnishes, electronics, etc. A cool attic is good for your home year round.
I have four on my roof for 23 years - no problems, no leaks, no noise.
In Florida these things are definitely not recommended although many roofers still use them. During hurricanes these turbines disintegrate. Best option is gooseneck static vents.
The four wind turbines on my house in the Southern California desert are driving me crazy. The squealing is absolutely maddening. I've taken the whole thing apart and oiled it, which worked for a while. Now the screaming sound is back. I climbed up there yesterday and emptied half a can of silicone into it, waited, checked it, put in more...finally it worked...and now it is squealing again. Though I live in a desert with highs into the mid 120s, I would give anything to stop the darn things from spinning, of those that still spin at all. A year ago, my son went up and covered the worst one, but that covering has come off. I am in my late sixties, disabled and dealing with cancer. I just wish I could shoot the darn thing to shut it up. Is there nothing on the market beside black plastic covers (which disintegrate within months in our high winds) to stop the darn things from turning at all? A DIY tip? I just can't deal with this anymore. I wish wish wish I had the awesome roof fan I had when I first bought the place in 2004. That made a huge difference in the heat in the house in summer. Now I can't afford another one (it was replaced when I reroofed and put solar panels up there, that first year). And as a physically challenged person, with a tilted roof it is very hard for me to keep getting up there to try to stop the screeching sound. Any advice welcome. Thanks.
Had 3 of them on parents house we sold. The did not squeak and spun easy. They were really big and put on in the 1970's, so big they had a huge elbow able to run them straight. House also had a broke attic gable fan which I replaced. We put on a new roof for the sale and I told the roof contractor to get rid of them. Only downside besides the look was during hurricane Isabel, they let water into the attic which ruined the ceiling, water stains and wallboard tape came loose. Had roofer put on a ridge vent, ad kept the attic fan and gable end vents. Attic seemed to cool fine. When they were on the ground, I was shocked at how big they were. All 3 were in good shape and could have been reused. Only real reason I got rid of them was hurricane water damage caused by them.
I live in the northwest and we get lots of rain. I have a piece of plastic in the attic below the turbines and I have never seen water on them. My whirlybirds are mounted near the ridge and I made sure they were installed level. If your turbine is making noise or not spinning, lubricate or replace the bearings. Most manufacturers have a lifetime warranty.
I have had the wind turbines last 40+ years and used them in both upstate New York and Mesa Arizona. Never had rain, snow or hail come through into the building. In the winter they pull moisture from the attic space, while during the summer pull heat. So you can use static heat flow, power fan flow or wind turbine flow, the wind it free and uses no electric. I prefer them to all other ventilation types.
Thank you for you comment, may they continue to serve you well.
Same here, using them in Phoenix, Az with Lomanco perm ball bearing model. They are the best for active attic ventaltion!! That plastic ridge vent crap doesn't last here in the brutal AZ heat!
To begin with, in order for whirlybird turbines to work they need to be placed near the ridge of your roof where you can see the tops from the front of your home or they cannot catch the wind.
I've been seeing those on rooftops since I was a kid and I always wondered what they're for ;-;
Product design does make a difference. Lomanco Whirlybird® turbine vents are Miami-Dade Certified and do not leak.They are also guaranteed forever. You can not beat that! Like any home ventilation system the Turbine is an exhaust vent and must be properly balanced with proper intake. If you install a quality product like the Lomanco Whirlybird® as your exhaust of a properly balanced ventilation system it is no better or worst than any other quality exhaust vent. The problem you have is with using an inferior turbine vent or an improper ventilation system.
Thanks for your comments!
SelectShots SelectShots what about when there’s 3 feet of snow on the roof and the vent is frozen in place and leaking snow?? or how about the squeaking?? they leak all the time! people put buckets in their attic to catch the water from them ! horrible vents install the Air exchanger ventilation maximum! so much better. that’s a real vent.. your welcome
Did any one feel temperature is reduced after installed in closed the room?.. we are in India, very hot in summer and we having a closed room with single door only.. so i planning to install this turbine.. Kindly share your feedback..
of course, then the next professional says completely opposite. I says exactly what is a myth about these turbine vents. Even in winter you some warm air to get sucked out and circulate the air or you can get condensation as well.
They work. You are right on them pulling heat though. Although I don't think you need as much as they recommend. My house was born with one from the 50s. It had newspaper insulation and never saw water. Is under half the recommended amount installed.
What is better then a Turbine? All I have is one static vent and my attic is 150 degrees. I'm trying to figure out how to get some ventilation up there.
Turbans are usually made of cloth (worn on the head). Turbines on the other hand do have parts that can wear out, just like any other device
Wind guide vane with a large pvc pipe is the answer to cool down the house.
Just got 2 of these for my parents’ house, and they’re seem to have some leaking problem after the thunderstorms
Thats why you cover them up in the winter and actually the wind blows all the time in Texas not just winter.
most turbines maker in malaysia give 10-12 years support for each installation. if worn out, just ask them to replace
No proof as to what you are saying Gary. If it's installed correctly for balance and weather proofing, they work. Nothing lasts forever, but these do last a long time. I suggest the galvanized over the aluminum, much heavier duty.
The empirical evidence obtained, backed by hundreds of photos - show what I am talking about. There is, in the areas of the country where I have worked, overwhelming evidence of leaves below the whirlybird vents, and insulation damage along with drywall ceilings with water stains.
This is my conclusion after being involved with thousands of roofs. Others who have more data, could prove me wrong, that has yet to be done.
However, the other side of the coin is, from your perspective, the roofs you have seen, you are probably right in those circumstances.
Either way, your opinion is appreciated, and I respect your findings.
Thanks for your comment.
Don't they put sealed bearings in these?
LOMANCO sells whirlybirds that are guaranteed to be oiled forever. I just put one up, (i'm a woman) .....my neighbor has had one for 30 years and in the 40 years she has owned her home she only replaced her roof once. It was just replaced this month and they put the same old WHIRLYBIRD back up ....
I have an indoor pool. Replacing the roof (leaking, poor previous install). Never insulated before. Planned to be lined with sisalation/sarking. No insulation as concern about moisture/fungus. Considered 2x whirlybird for better ventilation for pool/water moisture, bit now hearing how loud they are is putting me off- even more reading what youve written. Are vents worth it in my situation, & if so, solar vents? Any opinions
Mine make the same noise so I just lube the cup the shaft sits in! 30 + years old
I've had mine on my roof for over 20 years with no problems. Northern climate. They don't get covered up with snow like ridge vents or the flat plastic or metal ones. Never have leaked like the flat plastic ones that were on there. They leaked from day 1.

If you are worried about it pulling rain into your attic just "bag it", tie a plastic bag over it in the winter months.
You know they have covers for a turbine vent right… might set ya back about $12.00 each if you can afford it, I’d buy them and put the covers on in the winter time. That’s what we do here in Arizona… maybe they do things a little differently in Texas however.
Gary can you please advise me on what is better than Turbines? I live in Los Angeles, CA and summer time my attic retains heat. The attic has side vents rectangle shape 16 X 6, but I don't have top roof vents, which I think will really help. The house was built in 1948.
Send a few pics, of the vents, spacing and the elevations showing the roof; gw@exteriorsbygarywhillock.com I will take a look and give input
What
Use Lomaco brand turbines and they'll never squeak. Cheap turbines will squeak.
I've never seen a quality turbine leak in the heaviest of rain....ever..
You're not supposed to hold heat in the attic during the winter. You're asking for condensation problems in Texas.
Can I cover mine with plastic? And in the summer?
I just covered them in the winter so they did not turn. Used black plastic bags
I also would use axle grease to lube them and no sound. Easy Peasy
Did you feel temperature is reduced after installed in inside the room?..
I have a turbine with one of the pieces flapping loose as it turns. Do I have that secured with a rivet? I'm sure the turbine doesn't need oiling...it's just that one of the pieces is flapping in the wind.
Thanks for watching my video, Wind Turbins are easy to replace, there are other options for venting also, simply find someone in your area who knows about venting a roof. Best to you! GW
My home has a wind turbine mounted near a bathroom that is on the septic tank line. It is 12 years old and all is well! Have another bath room further away with alike set up, 2 to 3 years is long as a wind turbine will last! They are a necessity here. Have one on a metal storage barn removing heat constantly. Been there for a long time and does a fair job venting hot air. No rain has ever came in through this turbine! None of these turbines are ever oiled! West Texas! Some time wind turbines can be helpful, useful and sometimes they become a pain as they can deteriorate rapidly and that means money!
Thanks Gary, quick question. I have the same turbine here in Canada, Ontario, and the top of the axle cap broke and the turbine cannot be kept in the centre and rotate. Everything else seems ok. Would you be able know where I could find this top cap spare part, please?
Parts are difficult to come by, and cost as much as a new one. Sorry, we don't like this method, but it's what is happening. Good luck.
It is exactly that sound i am hearing from roof of my house. It is disturbing in the night and I wondering what to do about that.
You can find something like this on the Avasva page. Full step-by-step instructions right on your desk.
I thought they spun off the heat that accumulates in the Attic doesn't heat rise in pool air through the soffits
You may not like them , but they do work .They suck the hot-air out.
My house has two electric exhaust blowers, one for each attic. The blowers are temperature controlled and will only kick on automatically when the attic gets hot. These blowers definitely save on our electric bill since it is able to evacuate all the hot air that can make its way into the house. Cooling a 5,200 sq. ft. House with three compressors ain't cheap! During the winter, it obviously won't kick on and the flapper on the fan shuts when the blower is off.
The blowers are 1/4 HP and don't consume that much power since I wired them to use 240v. If anything, they probably add $5-10 to the bill every month.
The only issue is that they have to connect to power and they do make noise that isn't loud or annoying, just noticeable. Using 120v would increase the power consumption but they really only run intermittently so it's not a big deal.
My grandfather has the spinning turbines on their house being an older home and they haven't had too many problems with them. Every once in a while they need to be oiled but that's it. We did have to replace the bearings in on of them but those turbines are over 45 years old on the original bearings. They work ok for him, but they don't full out the heat as fast as he wanted.
Power is measured in watts. If wired 240 or 120 you might use half your amperage but your wattage is the same so the power used would be very similar watts = voltage*amperage. Say it's 120v * 10 amps = 1200w but at 240 it would be 240v* 5 amps =1200w .
I had to remove the electric exhaust blowers on my house in Florida and replace them with passive gooseneck vents. The problem was the electric exhausts were sucking all the AC out of the house mostly through the 52 can lights on the ceilings. After replacement my electric bill went down 20% during summer just from the AC savings alone and attic temperatures increased by no more than 5 degrees. This was detected during a power utility energy audit and I thought the trade off made perfect sense.
I INSTALLED 3 9F THIS AND MY ROOF STARTED TO LEVITATE! 😓
LOL
Since when would you not want your attic temperature to be same as the ambient temperature? This guy is complaining about heat being sucked out of the attic in January? The last thing one would want is HEAT above the surface of the insulation (in the attic space).
Thank you for your comment.

Good so what do u recommend 😅
Thanks for your question, every house is different. Currently, one house we are doing, we have added baffles in the attic to contain the insulation, then cut in soffit vents, 2-1/4" of venting for 170 feet around the eaves, vents are perferated vents to keep bugs out. Then we did a ridge vent on all ridges, (a gable roof, multiple gables), allowing the air to just flow. Here is a link on another way we did one, maybe it will help give you ideas. ruclips.net/video/nxd7vCh7lZg/видео.html
Best of luck. GW
Turbans are worn on your head. Do you live in agrabah?
I think these turbine vents are really ugly even when they work properly. Driving around in my neighborhood, I have seen at least 6 or 8 houses where it looks like their round turbine vent has become dislodged from its original installation and those round vents are just dangling sideways off of the vertical pipe. So just the metal tube sticks up from the roof and it looks like the round turbine vent is only being held onto the side of the tube by one or two screws or nails.
We get wind gusts up to 60 or 70 MPH here every year, so perhaps the wind is blowing all these turbine vents off of their pipe tubes? How are these turbine vents becoming detached from their tubes in my neighborhood?? What happens to these homes' turbine vent tubes when their top turbine gets detached and just dangles on the side of the tube? Does that mean there is a big open space for rain and snow to fall straight into their attics?? A lot of these houses with their detached turbine vents have been like that for several years now. These are all two-story houses, so these homeowners cannot even see their damaged roof turbines from their front or back yard because you only notice the detached turbines if you look at these roofs from a distance away.
CJ, not surprised. This too has been my experience! Thanks for your comment!
That kind of turbine ventilator, when working/maintained properly, does keep rain out. For example, Air-Vent's Turbine Ventilator, has a Miami-Dade Approval, which requires that it not only won't be damaged by high wind, but that it pass the standard test TAS-100(A) to prove that it keeps 99.95% of 110mph wind-driven rain out.
You have to lube the bearings every year or two to keep them operating smoothly doesn’t take much time and it’s easy
We're hearing that noise right now from ours..& it's 16 degrees..so annoying.
Turbans, lol.
Yes
I would like to see one spin.
Anyone know how to stop them from spinning altogether? We want to stop using them and keep them static.
Many people use a simple 3/4" screw, drill a hole and install a screw to keep them from turning. The only problem is, they could leak in a hard blowing rain!!!! Best to have them removed. Best of luck and thanks for watching my videos! GW
No shit! Anything that have moving parts would eventually wear-out, including roof wind turbine
Whirlybird vents are a huge energy waste unless the attic is airsealed!
I had some put on about 30 years ago. Can those be serviced?
New Lomancos are not that expensive and have a lifetime guarantee. Just had 2 installed to replace galvanized ones from the 60's.
@@josephtravers777do you have to tear the roof back and replace the entire unit or did you just replace the top part that spins?

How would you vent a free standing garage with a hip roof? I want to finish the ceilings and walls for a workshop space
What part of the country, what climate do you live in? GW
This is in the south east. Temps to the low 90’s and 5 degrees with 8 to 10 inches of snow because of elevation in winter. There is aluminum perforated soffit but between the rafters it has blocking so I don’t know how that can vent thru that. Has four mushroom type vents in each roof section near the top ridge.
I would think an open vent ie pipe, mounted high, would suck more air out due to venturi effect, and w/o the lost energy and hindrance of the turbine . Though of course you'd need a way to keep the rain out.
I want them for my garage it gets terribly hot when garage doors are closed any better ideas???
There are a number of good venting methods. To do a good job requires knowledge of the conditions.

Vent intake out turbine vent
Turbines are bogus. On a hot windless day, people see the turbine turning. They know that hot attic air expands, creating higher attic air pressure which escapes through the vent hole. If that hole has a turbine mounted on it the turbine rotates. But that rotation does not in turn pull more air out of the attic. Actually in this situation more air would escape if the turbine were not there blocking the hole area. Part of the energy of the escaping air is sacrificed in turning the blades resulting in less hot air escaping. On windy days It seems intuitive that the spinning blades act like a fan and draw air out of the attic space. No. Air is drawn out because wind blowing over the roof has less pressure than the inside the attic. If there is a hole in the attic, such as at the turbine, the air moves from high to lower pressure. The wind spinning the turbine does not create any lower pressure than a simple hole in the roof. Again, it is the opposite because the turbine blocks the wind over the hole and therefore raises the pressure at the hole. The delta inside/outside pressure at the hole is less with a turbine; therefore, less, not more air leaves the attic. Of course an attic vent hole can’t just be open to the elements, so do turbines block less air than a simple turtle cover. I don’t know. Just saying that turbines are not at all what most think they are.
Sooooooooo it takes 5 min to take it apart and grease it,as a home owner you should hire someone or yourself to step on your walkable roof at least once a year and inspect...dummy
so what do you recommend to keep attic cooler?
The two top options are carefully selected Ridge Vent or Dormer Vents combined with Proper Intake vents. In the following video we added full perimeter intake vents with the Dormer Vents. ruclips.net/video/nxd7vCh7lZg/видео.html
fiapop I agree with Gary in that a " Passive " ventilation system will outperform an " active " vent system that uses wind powered Turbines ,or thermostat controlled electric fan vents , a passive vent system should consist of 1 standard can vent for every 4 squares of roofing ,so an average house of 20 square would require 5 standard can vents ,in order for the passive or active vent systems to work properly a roof attic will need the same number of sq ft sofit vents as roof vents at a minimum ,I prefer to use 20% more sofit vent space than required to make up for vents that can become blocked with dust or insulation ,as for using " ridge vent " systems you should never use any ridge vent system to replace or eliminate standard can vents ,as has become modern practice, in order for a ridge vent system to REPLACE can vents only 1 type of ridge vent can be used ,which is a metal ridge vent that installs directly over the peak after cutting out 2 inches of peak ,the metal ridge vent systems allow for a free flow of air ,the ridge vent systems where you roll out a thick fibered Matt, then install shingle cap over top ,or the plastic vents you lay over the peak and install shingle cap over the top do not offer the same unobstructed air flow as a metal ridge vent that does not require shingle cap installed over top .
The only houses I ever install ridge vent is in areas of the home where there is vaulted or cathedral ceilings ,on all homes with 100% attic space I use 1 can vent for every 4 sq or 400 sq ft of roofing ,active vent systems like powered vents and Turbines do not offer a steady ventilation and can increase your heating & cooling costs .
BTW my credentials are 35 years as a Foreman Journeyman Roofer & Waterproofer with roofers local #149 Detroit Michigan ,I attended 4 years of trade school to become a Journeyman Roofer as well as attending the courses in HVAC " ventilation " and roofing related plumbing & sheet metal required to become a Master journeyman ,the points Gary made were valid, items like turbines, powered vents and shingle over ridge vents are made to appeal to the homeowner ,not the professional roofer ,the roofing industry standard is still the time tested & proven passive vent systems Gary outlined.

SO WHAT DO YOU USE ???
A good question. Thanks for watching. Every house, every roof is different. Have an expert, (far and few between) help with this or do some good research to determine the best way. Here is an example, not for every house, just one example: ruclips.net/video/nxd7vCh7lZg/видео.html
