Installing Attic Fan To Cool Down My house
HTML-код
- Опубликовано: 1 окт 2024
- During warm summer days, the temperatures in your attic (hot roof) should be between 15-20 degrees higher, resulting in cooler temperatures inside the house. Poor inadequate insulation and poor ventilation temperatures in the attic can range from 120-150 degrees. To help lower energy costs an attic fan can help also lower temperatures inside your home up to 5 degrees with an appropriate sized attic fan.

IMPORTANT! If you're gonna do this yourself, Be sure to add two screws on top of the vent flashing and cover them with sealant as well. Also, I nailed down the roofing nails that I loosened up with the pry-bar, just didn't show on camera. Keep crushing it!

PSA! If you're gonna do this yourself, Be sure to add two screws on top of the vent flashing and cover them with sealant as well. Also, I nailed down the roofing nails that I loosened up with the pry-bar, just didn't show on camera. Keep crushing it!
Should have shown inside temp before and after !
Use sealant on the screw instead of on top of the screw. And more sealant under the side of the shingles that are cut.
Nice product
but what about when it's winter?
@@antdx316 Better cover it or snow will drift into the house
You were just casually sliding off your roof??? Scary. Luckily you were able to stop.
Roofer here, the row of shingles above the screws should be on top of the fan also, and we always do a line of tar all around the edge of the metal where the shingles are going to meet, resealing that edge just for some extra protection. In addition to the caulking you put on top of the screws, I like to put a dab of tar on the shingle where the screw is going to drill through. Just for extra insurance down the line. Also nailing the shingles back down all the way around the fan is kinda a must, not only for the shingles but for the vent itself, idk about those solar powered ones but other ones can make a lot of noise if not nailed down properly. Not hating or trying to blast or anything, just tips and stuff for anybody.
I work for a solar installation company. You would cringe watching us screw 90 lag bolts or even several hundred deck screws into a brand new roof.
Agreed. You don't want the water to get under the shingles through the capillary effect. Have to protect the roof from water damage.
This fool doesn't listen to anybody
They're relatively quiet compared to the line powered version. My 25 year warrantied solar fan lasted 3 years. I contacted them and they shipped me a new electric motor. Whoopie. There's just no realistic way to replace it from the roof without ripping everything apart that I heavily sealed up. Due to the vaulted ceiling you can't get to it from the attic. I am not too worried about it because when I cut the hole in the roof there is a huge rush of hot air coming from the opening. If the fan wasn't seized up it would turn from the heat escaping. I can go up on the roof and feel the heat is still coming out so I don't worry about it.
My only advice to people is install it on a location that you can access from below in case the motor fails
What Do you Reckon Sir about a Port In the Wall High up at the top of the V as Opposed too some thing going through the Roof , Thats What I thought about doing at My Joint so its Got some air flow or at least some where for the hot air too escape
Awesome book that gives you step-by-step photos ruclips.net/user/postUgkxTNB_zFBSnTo_O1PqfVUwgi7ityw0JlKt and directions to make every day project. I can see myself making a few of these projects and giving them as housewarming and holiday gifts!
I was hoping for some performance data attic temps before after, AC cycle times, utility bill etc.

Ridge vents are better and work passively day and night. This is the old style vent with a little 5w fan, probably couldn't even cool my pc case.
@@dukee4333 its a big fan. 20 watt
Theres been studies done, they dont work
Groomer with Disney profile picture
It would have been helpful for you to post the attic temperature before you began your installation and the attic temp after the fan had been operating for a couple days so we can see what effect the fan actually has.
It will definitely cool your attic but if your house isn't super tight, it will be cooler because it's sucking cool air from inside your house so you may as well just ad an AC vent into your attic.
@@greghight954 unless your attic space is tighter than your house, I don't really see that being an issue
Should've done a temp test before and after.
I was thinking the same thing. See how good that shit works
same
It’s a gimmick and does not work, that is why he conveniently left out obvious measurements he should have taken. It’s basically click bait bullshit right here
It was only 70F when he did it. Let’s see what 105 looks like outside with roof temp of 140 and attic temp of 160 looks like before and after.
@@dustinlerch9272 you’re ignorant. When my fans were removed, my attic temp went up 30-50 degrees more than before. My ceiling and even walls, are like 100 degrees, and my AC vents are also hot. Again, you are clueless.
You're going to find water leaking the next time there's a major storm with wind strong enough to make rain fall diagonally or even laterally. I've seen water move horizontally on a roof parallel to the ridge line. You're going to want to properly secure the shingles and seal everything back around with tar not caulk which will degrade under heat.
Gosh
not even tar, because tar cracks due to age and leaks.. it should be properly flashed per the recommended instructional industry diagrams.
Seal it with lava, only way to be sure... RTV silicone with last longer than the roof
Architect here. I've investigated more than a few cases where mold occurred on the ceiling below the attic. Why? Negative pressure from an attic fan because calculations weren't done to confir that soffit vents provided adequate intake air. Consequently air was drawn from conditioned space below. BEWARE!!!
I was just thinking that
Bravo
Video on how to make a roof leak should be the title 😂😂😂
He needs content, which is why he puts out stuff like this every so often. This could have been a good video if he had done it right. It would have taken maybe 3-4 hours of research before executing but he just decided to wing it as usual. You can really tell the difference in his video quality when he research on the job before. The fact that he's up on the roof with no safety equipment at all is very telling. I get it, we probably would do the same thing ourselves, but when you're presenting to a mass audience you should show how to do things the right way.
@@plasmac9 totally agree
I feel bad for the person that buys this house in the future.
@@plasmac9remember the sauna video lol
😂
Always a scary proposition to cut a hole in a perfectly good (i.e. non-leaking) roof. You are a brave man. Hope the fan helps.
@@tailgatecarpenter26 Someone needs to invent insulating paint.
@leon Some1 did a test and showed it was a scam lol
They dont work as good as you would think. Having ridge vents and vents in soffits create a natural air draw as the hot air rises, it sucks in air from the soffits
* Before putting ridge vents on your home, check out the problems that can occur with them.
As a roofer I'm more then sure your gonna need a few more then that to cool down your attic
If you're going to do this and have access to the attic put a nail through the roof deck from inside. That way you know for certain you're missing joists and the hole will be centered. Also make sure what you're buying makes sense for your attic space. Is it going to be sufficient to turn the air over enough to actually make a difference. Do you have enough ridge vents that this won't even do anything? And if your house isn't tight this could cause conditioned air to be pulled into the attic instead of coming through the soffits. If it's just pulling AC/heated air from your house into the attic it's costing you money.
Just a note. You might not want to seal the bottom edge of the roof vent. The idea is when, not if, water gets in it has somewhere to seep back out. Also, it is generally recommended to use tar, not caulk in this case. The tar based sealant tends to be much more heat resistant than the calk, which is a must on a shingled roof.
all tar cracks over time , it helps to have mesh reinforcement to hold up to the cycling of heat
Butyl
Blackjack.
Poly-Urethane is better than tar by a mile.
@@michaelsatterfield7944
yup, butyl...harder to work with because it is so sticky and stringy, but it
will last the longest...Gutter seal, (not silicone) is also good for nail heads.
Would’ve liked to have seen how much of a difference it makes in the attic
Chris Catalli thats really what i wanted to see since his attic space looks big ?
Probably not that great considering how slow that fan was turning! Hot air in hot air out!
Probably very little if anything
@@cybersamiches4028 😑
Mine lowered the temperature considerably!
Hey partner, a 10" long piece of string would have worked wonders. Tie the string around your sharpie. Then measure out from your screw 7". Tie the other end of your string onto the screw leaving it where you're marker falls on that mark you made. Anyhow well done, job looks great. And those fans are awesome.. Never seen one like that before.. Thanks for another cool video..
Yep and use a white china marker instead of a sharpie.
@@joeyoungs8426 yeah that's true. I actually had forgot all about China markers.. thanks
@@tailgatecarpenter26 oh yeah, absolutely..
* Better make that 7 1/4 inches to get the required 14 1/2 inch hole.
I see your problem right off with venting. Not enough vents. I have a 1300 sq foot bungalow & have 5 vents + 2 vents on the build out. No need for a power vent. I shingle homes all across Canada & the biggest problem home owners have is they think a fan vent will help. All it does is create hot & cold spots in your attic .
You Should have just said no to that free roof vent
just a little tip many of us roofers use will maybe save you a lot of pain or even death ......find you an old couch or mattress topper use the foam to sit on will stick like glue and 2 pieces will help you move around without slipping move from one to the other and never leave the foam .....old roofing trick
What was the attic temperature the next day? How much difference did it make?
@Girl On A Quest yup
That little fan isn't going to do much. Plus, it will create a vacuum inside the attic. Depending on how well his house is sealed, and the vacuum can draw conditioned air from the house.
Depending on the build......these fans can be detrimental and cause the opposite of the intended result. If the conditioned living space below is not well sealed, the fan can create a light vacuum inside the attic causing the cool conditioned air below to be sucked out into the attic making your AC have to work harder. I considered this for my home but the 1997 build quality deterred me due to this.
Thank you. Was just about to order one and now I have something to consider with my home from the 70's lol
Yes !! Only real way to do this is with foaming everything!! But if you can do that you mine as well just condition your attic space so your hvac doesn’t work as hard !
My house was built in 95 I think. We had an attic fan installed and it helped a lot in the summer. The AC barely worked up there but we got it fixed between insulation, duct sealing and an attic fan.
Do you have a vented soffit? Wouldn't it prefer the path of least resistance to the air flow - i.e. that soffit?
@@mr.g937 I have a vented roof and soffit . But when you add a forced air current higher than the standing air around. It will suck the air conditioning out of the house. Through hole’s etc from the living space. If that area is completely sealed off good your great .
I clicked on this video for the sole purpose of laughing at mistakes.
I wasn't let down.
You're going to have problems in a year or two 😉
🤫 Do you hear where the drop is coming from?
There is a stunning lack of venting on that roof. We recommend a standard vent for every third truss bay. You have to ensure the soffit source is continuous and open with vented soffit.
Sider here. Can't tell you how many jobs I see with no vented soffit. It's so annoying
@Repent and believe in Jesus Christ He died badly.
Your childhood delusions are of no interest to anyone
yes, i believe they space out the box vents evenly so there is no imbalance.
@@SeattleBoatdog delusions of .?
As having done roofing the problem with the install is on the lowest two screws. Notice there isn't any caulk on the sides of the flange that's part of the fan shroud. The problem with this is that water can get into and through the sides of the shroud next to the roof and leak down the screw and into the attic! Water can travel horizontally!!
You must match intake area to exhaust fan specs, Exh fan manufacture will provide the required number of sq inches of intake venting to match the fan, could be on soffits. Doing this will help to NOT create a vacuum in attic pulling your conditioned air from living space. You can OVER exhaust your attic.
Crab walk on point good sir!
Well you pretty much wasted your time and money by just putting that up. Fans like that need to have a sealed roof. If you have a ridge vent (or any roof vent for that matter) you need to cap it off cause if you don't it'll pull air from the other vents (outside air from the top) vs the soffits at the bottom rendering it useless. I would have also screwed/nailed the rest of the fan down at the top too, to eliminate vibrations along with sealing it with tar around the edges of the fan and the shingles for added piece of mind.
Why would that be useless? It’s still adding a lot of air flow to the attic space.
@@JWEX500 Because it’s not a matter of just having airflow, it’s how the air flows (you can be in a hot car with all but one window up and a fan blowing inside, it’s still going to be hot…Open another window on the opposite side and you will be much cooler). Heat rises and instead of pulling cooler air in from the bottom of the soffit and expelling the hot air out of the top, it will pull cooler air from the top of the roof and then pull that same cool air right back out. While technically it will still get some of the heat out, it’s vastly less than what it would from solely pulling just the hot air out and you’d be better off leaving just the box vents at the top with open soffits.
@@JWEX500 I’m a roofer and I can tell you he knows what he is talking about, you should never have both active and passive ventilation systems either one or the other, they work against each other in situations like this, will this do some venting? Sure, however it will work a lot better if you did either one separate, that roof definitely needs more venting though, those box vents don’t ventilate very well, I would have gone for a ridge vent or possibly off ridge vent system depending on how much space I have to ventilate the ridge. Or I would have installed another solar powered attic vent on there and taken out those other passive turtle vents to ensure better airflow.
Well how else is he going to drop his amazon link for this 350 dollar piece of junk?
My father installed a huge fan in the ceiling to cool the house. It was so powerful it sucked ashes out of the fireplace. The fireplace had a grill to cook on.
Its definitely gonna leak. As for the other vent you showed... they didn't put screws in the bottom. Those are sealed using sealant and nailed at the top under the shingles...
A high school maintenance man installed ours. I had to redo it to seal it good on the inside. Now it's worn out. I heard it's better to use a wind powered version. The motors die quickly from the heat. Most have sealed bearings, so oiling doesn't help. I was told just to have a vent. Put the fan in the attic room ceiling like a bathroom fan. Less heat, longer life.
I would definitely still put sealant around all the edges just in case.
I was going to do this on my house in San Antonio and it would have taken years to recover the cost. It was 180 degrees in the attic.
I'm in San Antonio as well, my understanding is these fans don't work. What's worse is they are likely to pull cold air from your house into your attic.
ruclips.net/video/_pQ443d-NsE/видео.html
Lol years? No
@@jamesbizsYou can do the math if you want. I am not sure how you can determine the cost saving if cooling the attic one degree. The unit cost about $140 when I wanted it. It would have taken several of them to move any air. LOL.
Powered Roof vents (solar or otherwise) depressurize the attic and simply suck air conditioned air into the attic. They don’t save energy and a hot attic is far less of a problem then a air leaky ceiling. So it’s better to air seal and insulate the ceiling and let the attic stay hot.
This may or may not achieve the intended affect of cooling the house. After watching all of Matt Risingers attic videos I’m learning that the home building/improvement industry at large is not very knowledgeable on comfort, efficiency, and building science. Basically, 90% of what we do is wrong.
He's literally working against himself creating negative pressure in his house. It will be even more humid inside.
What's Mr build it. I've been building houses and remodeling for 23 years. I really appreciate you taking the time to make all the videos. Thanks.
Glad you're not doing this on my roof lol! Good luck with the leaks !
Are there any downsides to doing this? What about those of us who live in a mountainous climate that sees fair amounts of snow in the winter? Any issues with excess moisture/cold air getting in during those months? Definitely considering this on my house
Not sure about the snow side of things but if the angle of your roof is too steep the fan can create quite a hum at various times of the day depending on where your solar fan is mounted in relation to living area AND sun position/power to the fan (low power/sunlight makes the hum worse). My house is generally quiet so any noise is heard and the fan hum is no exception unfortunately.
In my limited experience installing chimneys, the best way to mark a shingled roof is with a yellow crayon. I’ve also heard white sharpie but you’re not always gonna have that and probably don’t want to take a trip to get one. If you have kids, you have a yellow crayon. Though it’s best to get one that’s meant for the job from your local hardware store (it’s thicker and stronger, less likely to break on you)
Lol, I am from the old school when we still used blue cake chalk.. I bet you remember that. Good stuff though
@@krakenwoodfloorservicemcma5975 I’m just a young guy. I’ve used chalk lines before, but not on roofs. When I’m cutting a hole for a chimney, it‘a a circle I’m going to cut. I’m still terrified at cutting holes in roofs, where you can mess up and end up having to replace shingles or plywood, or just patch material if you’re lucky.
I’ll give you a blast from the past I learned from trade school: plumb bobs. Never knew those existed, but indeed there was building before lasers. Cool stuff.
How about pink bro or green.
There is NO WAY that little fan would do anything. I have done extensive experiments with attic venting and only ONE THING i have found actually works. Paint the roof SUPER HYPER WHITE with hydrated lime. Vent fans didn't lower my attic temperature more than 2 degrees! Most men put the fan in... and say ITS FIXED. But I actually measured before and after temperatures. My attic was about 159 degrees... then the attic fan brought the attic down to about 157 degrees. Painting the roof super-white made my attic about 110F degrees!!!! Didn't require any fan or any hole in my roof. The only problem is now-a-days, you can't buy hydrated lime anymore.
Fan vents lowered my attic 30 degrees. So you’re clearly doing something wrong
in INDONESIA my country... you cannot walk with easily on the roof LIKE THAT...
without knowing where is the strong frame roof or without bringing PLANK WOOD... or you will fall down through your house
Keeping your attic ventilated is about more than simply adding a fan. An attic requires balanced ventilation, which means you need equal amounts of intake and exhaust. If you just add an exhaust vent you're going to create negative pressure and it's not going to achieve the result you want.
He may have a fan inside the house that is his intake into the attic. A lot of people have those that don’t have an attic exhaust.
^^^oh goodness. Lol
Yeah, well, it can be seen that there are several other passive vents on the roof, so it can be inferred, that soffit vents were also installed when the house was built....
@@Quickened1 This is meant to be a DIY video clearly for people that don't know these things or cannot make those inferences. Simply adding an exhaust vent will not solve people attic ventilation issues.
@@trent210 uh, that would certainly be a very silly thing to have
Best part of your videos is you talking to yourself. So good
Any noticeable gains?
$10 says the roof leaks within a year
That's insane. That roof looked steep. Sounds like $50 and case a beer to buddy type project to me lol.
Different states roof differently, some worry about rain, others worry about ice damming. If it's for a friend, I'll take the case, otherwise I'm not getting on the roof for $50....
Unless your attic floor is sealed well & the soffit vents are clear, these cause air to be pulled from your interior to the attic. That means air from outside is pulled into your interior. So the attic is cooler but not the interior which is what you care about
I think it’s supposed to be so your AC unit isn’t as hot which should make it run better and easier
@@robertct06 My understanding is heat soak from the attic causes the rest of the home to heat up. Improving attic ventilation will help you use less AC by preventing that heat soak, but it doesn't directly cool the AC unit if that's what you're saying.
@@DeilGrist yup. Exactly what I was trying to say lol
If you would've tied a string 14 1/2" to your screw, it goes much quicker, only verify with the tape after. A tire crayon also works well on asphalt shingles. Not criticizing you, only trying to help in the future. Good video.
I'm no professional by any means, however using silicone as a top sealer where you should have grommet screws has proven to fail time and time again(silicone fails from my experience on repairs and pulling caulking off of previous *fixes* with little to no effort)(Mastic/Rubberized flashing cement would work better because it is designed to adhere to asphalt products). Secondly, Notice how on your other RVO-38 vents, the laminates have coverage over where you cut the hole into your roofing system and when your silicone fails under the vent you will have a leak because water runs sideways with external factors and you have no material preventing that. (laminates cover to the bottom of other vents, past roof penetration) a.k.a if caulk fails you could stick your finger under the vent into the protrusion.
Could this also be accomplished with some sort of a powered gable vent high up in the attic wall? I like to avoid putting more holes in my roof than I have to.
Yea it can
Exactly my thought. Why you would make a whole in your roof when there was a partly sheltered gable escapes me entirely
I’m not a dummy, stop saying that😂
I have Whirlybird Spinning Roof Vents which simply allow the Hot Air to passively Escape from the Roof whilst keeping the adverse weather out.
You should check with a roofer if you have a ridge vent the fan can work against it causing airflow issues also I would recommend centering it in the middle of the attic
Came here to say the same, just had our roof re-done and the guys said the existing fan would be taken out as it will do just this with the new ridge vents.
I can attest to that. I could feel air being drawn in from the ridge vents but that was simple enough to block with thin pieces of Styrofoam
I've been working with attic insulation for a very long time and had alot of conversations with roofers about this it can actually cause more harm sometime if done incorrectly glad to hear the Styrofoam helped
@@MichaelDellAccio I will say ridgevents with out open soffits won't do much but if your soffits are open then yes you do not need a fan
can't tell if it's in the middle of the attic. could have a vaulted ceiling
Nice induced draft fan for supporting a house fire !
The NFPA does NOT approve of any automatic attic exhaust fan without an over-temperature shut-off !!!
The solar fans are a fire risk?
You all know these things do nothing but spin and suck cold air from inside your home. They're even a code violation in some places. He needs a roof ridge vent and more insulation in his attic.
* Ridge vents are in theory a good option, but have you ever looked into the problems that can arise from using ridge vents? Check it out sometime.
That's gonna leak.
You shouldn't be mixing types of exhaust ventilation. You have created a short circuit in the airflow pattern so most of the heat isn't removed.
Indeed, you will likely be pulling air into the attic from the vent on the other side of the ridge and not exhausting much hot air from inside the attic. But a great video otherwise!
I could feel the discomfort in this video. I get it, I talked a big Starlink game until it came time to mount Dishy. You should have included the parts where you got off and back on the ladder, getting back on to climb down is always the worst.
Yikes
Guys pleaase DO NOT do this to your home
please explain why.. I was going to add a couple of fans on top of the roof to bring the the heat...
I would say just for the preservation of your roof go in the attic and give the surrounding opening an extra bead of sealant. Just in case. Also gives you a chance to measure the temp and look for holes and pests.
8bit quality in a 64bit world. What I'd expect from Jennie & Davis... Not you.
Has the attic fan made a noticeable difference? If so can you elaborate
Can you answer my question? Or are you being held against your will.
What happens on the winter? You want to keep the heat in
Jumping onto a roof without a safety harness is like jumping into a boat without a life preserver. I appreciate the video but please be safe people.
That is not the smartest way to determine where to put the hole... there is no way to determine where the rafters are. You need to go in the attic and either drill a hole up in the center or drill 2 holes showing the limits of the rafters...
These solar ones are kind of a scam. Yes they do something. But they don’t have temp or humidity controls so they will not extract moisture in the air on cloudy days. A properly balanced passive system is the most effective. Not possible in all roof geometries though.
Exactly. People underestimate the amount of solar you need for something to charge and i guarantee you that fan won't be working most of the time. Most solar products are a scam.

If you want to keep your attic cooler, the fan will be fine. If you want to keep your home cooler, make sure your thermal boundary, which is your attic floor, is insulated and air sealed properly.
How cool will it be? 10 degrees less than outside?
honestly if you want to be certain about leaks, i'd just re-shingle that area around the roof. I've done what you did before & I still had drips. best to just re-shingle & tar that perimeter. personally i've still encountered problems doing that method. ideally the fan is installed before the roof is shingled. best to let the roofer be responsible for the leaks rather than the HVAC or electrician.
Waste of money. I had one installed, prior to that, I setup up a thermometer that showed me the average temps for the day. I monitored and noted this for a week before the install of the fan. The temps maintained the same for a solid week only changing when the outside overall temps changed. I kept monitoring it on and off over the next couple weeks and only noticed a 1-2° +/- change. IMO, Whole house fans don't seem to be a viable solution either. Several of my neighbors have them and they blow air from the outside, meaning you can't use them on hot days which is when you would want to use them. The only solid solution I have come up with is having a mini split AC installed. I haven't done it yet, I have too many projects going on to mess with it now but its on the to do list.
Living in socal I've never heard anyone complain even lightly about 70deg. Summers hit 120s here
I am no roofer, but there seems to be a few missing details here. How is everything sealed around the cut shingles? What’s the air volume in that attic, what the temperature differential from inside/outside? How much volume of air does that cheap Amazon fan pump?
Good video for safety this is not a DIY if you don’t get on roofs often . Roofing is the number trade in construction for most deaths from falls
Water will migrate to the underside of the shingles. Seen it happen too many times.
How couldn't it, he didn't seal much
Am I wrong?? I was always taught mixing vent systems in the same space can causes draft issues!!
No this is just youtube now, some guy without any previous knowledge will tell you how great a product is while he's installing it wrong.
The solar fan unit does not look very robust. Is it resistant to hail? Does it have a substantial warranty? I think wind is a better option for an extractor fan.
first that is not a ridge vent a ridge vent runs along the entire peak of the house, secondly putting in a power vent without closing off the vents you have ,will short circuit the system sucking air from the vents instead of the soffits, thirdly just put in a proper ridge vent which is fantastic in certain shapes of roofs like yours, but what do I know only been doing it for 45 years
These powered vents actually suck. Literally they suck not only the hot air out of the attic, they also suck the conditioned air out of your living space unless it is completely air sealed which 99% of houses are not. Not recommended.
So if you have soffits would you still need to have an exhaust fan? If so on roof top. Or side of house
Wish you would said what about winter climates? Is it taking your heat out? Where is this at because you never stated what state you are in. I live in lower Michigan and I get full sun all-day long. Love it
From what I understand, in theory the sun is lower in the winter, so the fan isn't as efficient. Not sure if that is fact
Thx! Your video gave me the confidence I needed to do my solar fan. Thank God I don't have a two story.
great video. any update? have you noticed your A/C working better? lower power bill cause the A/C is working less?
I just had mine fixed and its working properly now. Cant tell a difference with one, looks like you need multiple.
Should’ve called a roofer and ridge vented the home. Those solar power vents will still go out just like a regular motored ones will. You spent 600 on something you would need at least two of to pull the amount of heat from that attic space.
I came for a tempt test, Instead I came to a poorly installed Solar fan and no tempt test, Great. Human beings continue to amaze me.
I have a 28x24x12 garage. Non-insulated as it's just a garage. However in 100 degree weather it's too hot to stay 5 minutes. Really don't want to spend thousands insulating an area i'm not in much. Would this fan bring temps down enough make it bearable?
Brit here ~ Are American roof tiles just made of roof felt? Ours are concrete, slate or some other hard material like that. Cheers, cool video as always.
Good on your for doing it yourself. However those are not screw holes lol nails and nails only should be used on asphalt shingle applications.
WOW, this guy does not know roofing! pull up shingles first, install vent, then maybe some ice and water guard, then shingles. I'm a roofer that came here for electrical advice and saw it's solar powered. jeez! KEEP THIS GUY OFF YOUR ROOF!
I love how he blindly cut the hole. My god, that could had been a bad day x)
A waste of time. That thing (in hotter states) is going to run nonstop. Your electric bill will tell you what's going on. Should have installed a ridge vent. Works the best for $0.00 every month! Also, if you're in hurricane territory, it might just go bye-bye.... And/or leak like a
bee-atch.,,,
well, at least we'll know why he hasn't added solar panels to the house before this.
Amazing how many ppl subscribe to amateur DIYs. I never forget what I was once told : if you want to be good learn from someone who great. Want to be great learn from extraordinary. This ain't it.
These don't work. Save your money.
There's no way for 10 of these to displace the amount of heat buildup in your attic. You'd be better off with a tile roof (heat sink) and or improving the thermal boundary between attic and living space.
Just thought you should know. We studied these (useless) fans years ago.
I asked for 2 solar fans to be installed on my roof, the guy gave a $2,400.00 estimate (2 solar attic fans 35 watts) , I think is too much for this job, I appreciate any advice. Thank you
"black sharpie, on a black roof, when it's 70 degrees outside".........
While it's 105 here in Texas.. I'm wishing for 70 degree days.
You need to have a better camera angle…you can’t see what’s going on from the position they were recording from. Also before and after attic temps. Seemed like a haphazard video to me…
Do the calculation of how much wattage the sun is pumping into that roof. Yeah, an attic fan which moves a few CFM is going to make a dent in that...
Is your top floor completely air sealed? If not, that fan will be drawing conditioned air from the house.
Do your research folks...
I'm no roofer but I would seal way more around the entire thing and then shingle over all the edges
Ask the fastest way to do it, but it wasn’t the safest way to do it. He covered two rolls. One of those rolls have to go on top on the bottom he has the nail exposed. I nailed it in the top cement and I put water and ice on top so it ain’t going nowhere, but probably won’t leak anyway but if you do that like 20×1 of them will leak
