- What is Ice and Water Shield exactly? Ice and Water Shield is still a fairly new product in the roofing industry, but boy, it's made a huge impact on our ability to waterproof a roof and properly keep out water in difficult areas. There's obviously some drawbacks, but in this video, we are going to focus on the positives of #iceandwatershield and why we think it should be installed on every sloped roof. #roofunderlayment #peelandstick

Thank you, i'm new and today was my first day solo, you really make me feel a lot better and helped me a lot!
Cody, I love to hear that! We all got started in the industry some way or another so I hope you get a lot out of our channel.
Do a ice and water shield removal video for the time when the roof needs to be replaced again
It's on my roof here in Florida, I paid extra because I know better, I have it on my shed (no shingles) yes it just went through hurricane Ian, the shed is dry as a bone.
Good info. Just curious why you prefer not to use metal in the valleys ?
nice roof
Can I use this on metal roof like older mobile homes ? Will it stick to metal how sticky is it ?
Good information and a nice video!. I agree and I love ice and water shield and I use it on all my roofs just as you say. You mislead, imo, with a couple things I think are mistakes. Shingles are waterproof. When working, they do not allow water to seep anywhere. Water gets under a functioning roof because of: either being driven up by wind, through capillary action (water runs up between close surfaces that are not sealed perfectly), or due to condensation from under the roof (warm moist air meets cold roof). Ice and water shield, sticks to the underlayment to create a water proof barrier to protect the underlayment more or less from all 3 circumstances. Also the sloped edge of a roof is the "rake" you miss spell that in the titling at 3:11.
All excellent points. Thank you!
drip edge over ice and water shield and then underlayment over both? Manitoba Canada sub freezing 6 months a year
Aca en mexico le desimos carton lija base pero no se cuantos años dura yo lo puse en mi casa nomas puse el carton lija no le e puesto arenado
Is installing an ice and water shield system on the entire roof an overkill near the ocean? Great content and thank you in advance for your input.
If you don’t get ice, you don’t need ice and water shield at all.
Yah how about doing your whole roof with ice and shield in Colorado ,????
Regarding wind driven rain- would you use I&WS on the average home in southern Florida?
Yes, it's code in most of those areas to use Ice and Water Shield on any pitched roof.
I live in Climate Zone 2, zero ice or snow, just lots of hot days and occasional tropical storms and hurricanes.
Have a question for a new construction home.
Do you still recommend water shield on the hips, eaves and ridges for my location ?
I planned on installing it on the penetrations and valleys. Your thoughts?
I was considering OC WeatherLock Flex or Mat.
Andrew, most coastal building codes require it now. Basically, it's just going to help if water is blown up the shingle at the eaves and rakes. I am still a little undecided about it. Ice and Water Shield is an amazing product but it comes with a fairly substantial additional cost.
Time will tell whether it's really worth it in warm weather areas or not. As for the material you chose, either one is just fine!
Do you recommend for low slope roofs in central Florida? Thanks
Stay away from low slope if possible. More time for the water to find an entryway.
We put it on every roof in my company here in Texas
I agree man, absolutely no reason not to.
What area of the country would this apply? (ie northern states where there is ice/snow, as opposed to warm climates southern states)
That is correct.
I've noticed that the back of my house , when going into the attic after snow. The decking is discolored dark only about 2 or 3 feet , the rest going up toward peak is dry also noticed today a stain in my bathroom ceiling next to a high hat in that area.
Does that mean the roofer I hired 3 years ago didn't use ice and water shield ? Or can it be an ice dam from gutter ?
Bren, great question. I think you have a leak around one of the penetrations it sounds like.
I have a question. Our roof is approx 15 years old archetectural shingles and due to being a low pitch roof(2/12) the roof was 100% covered with I&W shield. I needed to pull up several rows of shingles about 5 feet wide to replace some damaged plywood. The problem is the upper half of each shingle is totally stuck to the I&W shield. I can remove the nails but it's like the shingles are grown to the roof. The couple of shingles I have gotten off ripped apart just above the nailing strip leaving the upper half of the shingle still attached to the I&W. Any help or suggestions for getting these up would be greatly appreciated. Thanks!
Shingles should not be installed on anything under a 3/12 pitch. If you can’t get the shingles off because they are stuck to the ice and water shield, sometimes they’re easier to pull off working them with a flat bar when it’s colder out, or actually heating them up with a torch. Which is extremely dangerous
Shingles should never be installed directly on ice and water shield.
@@jwatson181 I agree with you 100%.
My shed installer didn’t overlap the synthetic underlayment on the top cap of my barn style shed. There’s a quarter to half inch gap between the plywood pieces on the top and and you can see the shingles from the bottom. Is this going cause a problem?
No!
@@Maynardd Thanks!
Haven't watched the whole video yet, but i used to do roofing in saskatchewan and we always used ice and water on the eaves and other areas that are prone to ice/water build up areas.
I recently moved to Vancouver, BC and I have met 1 roofer who uses it. Its odd because they do get the occasional snowfall and under 0°c tempurature. Like most homeowners here have no protection if the weather permits ice damming here, which I don't get why they wouldn't opt for it seeing as it would be a costly repair if ice damming occurs.
I couldn't agree more if I could. We use it even in areas where ice damming isn't really an issue, but any place the roof is prone to a leak. I find it VERY odd that your roofers aren't using it way up there. For the cost to install it, it's a no brainer in cold areas where ice damming is normal!
Hi, on edges how far shield is best to have 3 ft or 6 ft.
3 feet is more than ample!
Can i put ice and water shield on top of 3 tab shingle and roof over with metal -- will it work over shingle
No. You can check with GAF or other manufacturer for questions like this.
My question and I’m sure it’s been answered but ignore my ignorance but aren’t you putting holes all over this stuff when you nail the shingles in? I’m no roofer just need a new roof I’m in central Fl.
Great question. Ice and water shield is designed to be self sealing. The tar-like bottom layer is designed to melt and seal around any nail penetrations.
Not every roof needs Ice and Water shield even in cold climates. If you insulate and ventilate correctly and your house is a basic ranch or Colonial with a 5/12 pitch or greater you will be fine with #30lb felt . If you have valley's then you had best install ice shield down the entire length an 8' out from each lower edge and 6' up. If your State requires it then you better adhere to those requirements.
If water gets under the shingles to the ice and water except for an occasional ice dam hasn't the roof failed. Doesnt water between the 2 just sit and rust out the nails and water soak the shingles from the underside? I do believe ice and water other then ice dams its original intention is a manufacturers con to increase sales. Thats just 50 years experience speaking.
Yeah,but it doesn’t breath and it doesn’t stop completely ice backup and leaking.
Thanks for your video. I have a question 🙋♂️
Why the roofers do not cover the whole of roof deck with ice and water?
To be honest when I think about other underlays such as felt, even synthetic ones, I don’t know how they can really prevent leakage to roof structure after hundreds of nail on shingles make holes on them?!!!
With ice and water, as they are self-healing, no matter how many holes can be made by shingle nails
Good question! #1 reason is that the homeowner does not want to pay for it. it's very expensive. Our high end clients always pay for it. But the average person does not want (or need really) to spend that much.
I only recommend it on a roofing system that will last forever, not asphalt shingles.
@@DigitalRoofingInnovations What do you mean "a roofing system that will last forever, not asphalt shingles."
@691norbert he probably means a metal roof
putting ice around boots and other penetration does not make sense if it does not go all the way down to the gutter... that's why it is not a code so first install boots flashing or other correctly because if these leaks ice and water around it doesn't help the leak is gonna be just lower
It will still roll down the synthetic. We do it so if there is a leak around the penetration, there is a secondary backup to prevent water from just pouring in.
In this case one can always overlap the ice and water onto the headlap of the course of shingle below the penetration to redirect any leaks back onto the roof.
I must disagree good sir. Straight a frame with no gables and or valleys. I run it in all my vallies and other problem areas. But if a roof has a good pitch and no trouble areas or vallies it's not necessary in my opinion. But we can agree to disagree. Better over roofed than under though. Thanks man
I agree with you for southern inland roofs. Coastal roofs and northern roofs where heavy freezing is common, Ice&water is more necessary. It can vary, and it is hard to have hard and fast rules since experience varies based on region and terrian.
It prevents the rain from being driven? Huh?
I like your style 😆 He needs to be more precise with his language. But this is RUclips so...
If you install this on the entire roof, there's no need for another underlayment, right?
* As I understand, if you put down asphalt shingles on top of the ice and water barrier without an underpayment first being applied on top of the ice and water barrier the shingles will get glued to the ice and water barrier. You'll have a heck of a time removing the shingles when you need to replace them.
If you have ice build up on the edge of your roof, it’s an insulation/ventilation problem.
When i did my roof, i put bituminous, self sealing, self sticking type of ice and water seal on the whole roof. Didn’t cost much extra, but the peace of mind is priceless.
Hue, there's a reason we NORMALLY don't put it on the whole roof, but that's a conversation for another day!
Isn't ice and water usually way more expensive vs synthetic paper? Ice and water is way thicker, so less square coverage in a roll compared to paper
@@Josh-ww5kz yes, it's about 4x the price, but you don't use it on the entire roof (unless the pitch is really low). We typically use it along the eaves and rakes (in a colder climate), target patch around boots or any protrusions, around the chimney, and finally in the valleys. Even then, you typically will on use 2 rolls on a regular sized house which is about $100.
No all the time is it ventilation problem. If so every last house in my area last year had it. We had fast partial melt fast refreeze with heavy snow fall and ice built up .
@@George196207 it is also an insulation problem. If you have proper insulation and ventilation you will not get ice back up.
It prevents ice dams? Is it heated? Lol
Sorry don't agree. Not every roof needs ice and water shield. It is only needed in a frost zone aria. I roof on the west coast, and you you can get a grid map for were the ffrost zones are.
If you are relying on ice and water then you have done a poor job on roofing it. Make sure your attic is insulated and vented right. Ice build up is caused by heat coming from your attic in the winter time.
Not the only reason. It can also come from poorly insulated windows and doors. Also, many local building codes require it and in my opinion, it's a far superior product than metal in the valley.
AROUND PENATRATIONS DOES NOTHING
Well, we 100% disagree. It provides a 2nd layer of protection when the rubber gaskets fail and most of the time, they fail before the life of the roof does.
Ass and water shield???
