Yep I’ve already experienced one that 1st gen peel and stick stuck to deck and shingles stuck to peel and stick and had to replace all 140 sheets of plywood but when roof was done it was before renail code so the only way to meet code was to replace the deck but luckily it was a insurance claim so everything was covered under the policy under the old rules , I’m sure under the new rules might be a different story 💸😆 Then I got to test out newer generation peel and stick on another house that was replaced due to a tree falling on house the first go around everything was going well then 3 years later another tree fell on the house and no shingles stuck to peel and stick , both roof replacements were insurance claims so homeowners didn’t care how much roof was , now she has 2 layers of peel and stick protection
Om in Fl., looking at a new roof. I have a couple bids that are using Perl and Stick OVER Plywood Decking. Are u saying, it's GOOD to use these days, because thats a question I had for the Roofer. Question: What about a follow up if needed, a tear off, will the Peel and Stick cause a problem? His answer wasn't clear, he was the salesman for the local Roof Company???? I remember his answer. After tear off, go back over the original Peel and Stick with New Underlayment? Now, I came back and said, that be all good if the Shingles came off clean??
Up North we are required to put Iceguard (peel and stick) 24 inches past inside of warm Interior wall directly to deck along eaves . If I was down south I would agree with you. I know metro Dade standards are high.Up here there are no nail I inspections etc. Ofcourse we don't have hurricanes etc. What we do have is a lot of ice in the winter. I appreciate the quality and care of your work. To many hacks out there.
Hey! Do you guys run peel and stick in the valleys first and then put metal on top? I am in a high debate with an installer! I am used to putting peeling stick on the deck and then nailing my valley metal over it and sealing over the nails. He swears that it is best to put the metal down, and then the peeling stick on top and into a degree I do agree with him, because in theory, it would take the sharp edges out of the wood and give the pill and stick and ice flat surface to lay on. I look forward to hearing from you guys!
Existing roof is near flat (maybe 1/8” in 12”) so we are planning to add tapered polyiso - about 1” to 7” with 1/2” plywood cover which will also help to match slope on adjacent new patio roof. The plywood will be screwed through the insulation to the existing 1x6 t&g deck Should we use nail down underlayment with peel and stick cap sheet vs peel & stick underlayment or direct peel & stick to the plywood?
This is a great question. Yes, if you are attaching to wood, I would use the nail base provided by the manufacturer. CertainTeed makes a low-slope roof system that is three-ply, and I highly recommend it. The first layer is their nail base, the second is base self-adhered, and the third is their cap sheet, which is the final product. If you follow this method, you can remove the roof in the future for replacement. It's a very solid roof system. The key to this is to stagger each layer so the seams don't stack up. Jason R
Or you can put synthetic over ice and water. And what's the difference from ice and water or synthetic as to trapping heat and shingles not lasting as long? Won't both trap just as much heat?
Recently we have removed roofs that had peel and stick directly to deck and have noticed a consistency of the shingles not lasting as long. I will always recommend placing synthetics down before just for the purpose of removal of the roof in the future.
@@eustisroofingcompany I'm in central florida doing my own roof. Do you recommend synthetic underlayment on deck and peel and stick over it? Or peel and stick on decking and synthetic over peel and stick? I'm thinking for the future if I need to replace my roof again and don't want the issues from the peel and stick not being easy to remove.

I'm from BIG ice dam country. Ice & Water shield has to go down on the plywood deck or it's worthless. Then install your felt or synthetic over the entire roof. That roof looked like it was an old house that had 1x12 plank sheathing. In that case it needs new 7/16 osb over that. I have a clause in my contract for bad underlayment. Peal and stick also needs to go in the valleys on the plywood. You put that down early in the morning. Before the temperature rises. I do high end roofs.
Liberty is a good product . Low slope roof you have some different options than your typical slope roof. On your next roof you can install insulation board or cover board over your liberty if it won't come off. I wouldn't worry about it plus you're in a colder environment than FL. We get extreme heat which causes more concerns with peel and stick. My concern is when peel and stick and Shingles melt together and it cost the homeowner more money to remove .
I'm in NY and planning to do liberty. Manufacturer want direct to deck but I'm concerned about when it comes time to reroof. What would you do and use?
Yea I dont have issues with the currect roof that people are pointing out no buckling etc. It looks real nice. But it is 12 years old and I know in the next couple years I will have to do something. I dont know how long they last. @@eustisroofingcompany Also just asking but can you put three tab over the existing Liberty??
@@StephenCunningham1 You are absolutely right to be concerned when it comes time for a reroof, people don't think that far out and is the root of the issue, it all depends on what type of roof it is and pitch it is. However first and foremost always follow local code and regulations.
I wonder if the older peel and stick has the same thing with melting to the shingles up in the Northern States where it does not get as hot or hot for as long as Florida does?
When the hurricane takes off the shingles, the peel & stick will stop the rain from entering the walls and ceilings. Felt underlayment will blow off with the shingles. Once the hurricane winds blow off the shingles, it continues to rain for hours. Peel and stick will then become the primary membrane and protect the home from water intrusion. Difficult decision, but just dont say you should never do it.
Putting a self adheard product is far better then not, but you must ventilate properly and you mus put the correct peel and stick down, high temp tile underlayment which is more expensiev, as in polyglass mts polyglass xfr etc. With that said if shingles do blow off the self adheard secondary water barrier wil prevent water inrusion, in addition to getting an additional insurance discount! Synthetetic undrlayment is not water tight unless shingles are installed the same day, been there done that.

Up here in the Jacksonville area, thanks for your info, I thought that was the case with peel and stick, that is sticks always to the roof decking, so I won't do that, you saved me lots of time, trouble and money.
I live in southern California. We have a 3400 SF house with concrete tile roof. What type of underlayment would be a good choice? We are thinking to upgrade the underlayment from felt to titanium synthetic UDL 50. Is this a good choice or should we stick with double layer 30 pound felt. Some of the local roofers do not recommend synthetic underlayment for tile. I appreciate your input!!!
SO I READ EVER COMMENT AND DEBATE. SO ESSENTIALLY ARE YOU SAYING IF I OPT FOR PEEL & STICK. BE SURE TO USE THE "HIGH TEMPERATURE" PEEL & STICK VS THE STANDARD TYPE. ? Plz correct me if I am wrong
I always recommend the high-temp peel and stick. I love every form of peel and stick. However, if you ever attach directly to the deck, I prefer high temp. This also depends on proper ventilation and if it meets code for the final roof product that gets installed. I have seen peel and stick fail and drip around the house, which is a huge mess. I have never witnessed the high temp doing this. It's a superior product and much thicker. I always recommend high temp with metal roofing and other high-end roofing products that last much longer than shingles. Jason

When you install ice and water shield on the plywood just remember to install the synthetic underlayment over the ice shield so the shingles won't stick.
I think the guy said to install the peel & stick over the synthetic underlayment so the peel & stick doesn't stick to the plywood causing a mess the next time they're removed. The peel & stick sticking to the shingles is not a problem.

I live in Orange County and looking to replace our 7600 SF Spanish tile roof with either similar Spanish clay tile or composite Spanish tile. Would a peel and stick underlayment be a good choice (we want the very best underlayment available regardless of cost)? Great informational video.
Yes a peel and stick underlayment is a must. Wouldn't install without it. It must be a high temp underlayment, we would love to quote it if your interested. Just let us know!

No, Boral Tile seal is not a peel and stick product. Boral Tile seal is a type of sealant used for sealing and protecting tiles. It is typically applied using a brush or roller to create a protective barrier on the surface of the tiles.

Torch used direct on wood sheathing to soften snow and ice guard might not be a be a good idea. Or.....maybe the best idea if you have incredible insurance.
Hey Jason, I understand your concern with peel-n-stick for the shingles roof. But what about a tile roof in FL? Would you recommend the same (nailable underlayment under the peel and stick) for a tile roof? Or directly over the decking? Thanks!
Great question! Direct to deck is best as tile lasts significantly longer than shingles as well as not effected by heat like a shingle install. Metal & tile installs are best to go with a High Temp Peel & stick right to the deck.

Ugh I am perplexed. What you are saying makes sense because the peel and stick or ice shield is going to bond to the sheathing. I am a house flipper. I was a contractor up North and did some roofing but live in sw Florida now. Im getting bids on a roof right now and everyone is bidding peel and stick to the sheathing. The last house I did we used synthetic underlayment and no peel and stick. The insurance companies gave the buyer a hard time about it. Some comment below saying that using the synthetic first is not ok with codes or manufactures so I am now totaly confused.

There are so many unsolved issues and code requirements in the entire peel-and-stick argument; it's kind of a mess. My main concern is that when the roof gets removed, it could be extremely time-consuming to renail the deck if needed. Additionally, we have personally seen peel-and-stick fail, causing tar to drip from homeowners' roofs into the soffit and around the house. So, I always want a way to remove it if possible. I think your point is good and is better than going directly to the deck. The issue seems to be long-term, and listening to the roofers who have seen huge problems, one of the biggest issues was shingles melting to peel-and-stick and peel-and-stick melting to the deck. Your way solves that. With that said, I am a huge fan of peel-and-stick; I just want to look out for the future and make sure it doesn't affect the homeowner in a negative way. Jason
I have experienced this as well in NE Florida and I have been skeptical to use peel and stick direct to deck for the reasons you mentioned, plus I have seen it buckle on our roofs and roofs that other roofers have done. I have asked a couple manufacturers about using synthetic as a slip sheet and they have said they don't have approval for peel and stick over synthetic, but you can use traditional felt under peel and stick. Am I getting bad information or is there a peel and stick that you use that has an approval to be used over synthetic?
Your question is great. There is a lot of testing being done to investigate the effects of peel and stick application directly onto the deck. If you choose to install over synthetic materials, I recommend following the synthetic dry-in codes and using a 2-ply system. This way, the peel and stick will provide added protection and you will avoid issues with codes.

I was told by a metal roofing material vendor that the peel and stick had to over lap 50% say 36 in width role needs to over lap by 18in here in Florida is that true?
This is true when it comes to synthetic underlayment. Some counties require 17 1/2" to be exact for 50% overlap. Peel and stick isn't required to be half lapped, only synthetic. This is all dependent on the county you're in. There is one county that requires 50% overlap because of the type of peel and stick. Half the lap of the peel and stick is nails and gets peel and sticked over. They do this so that the peel and stick isn't direct to the deck like in the video, if you have any other questions don't be afraid to reach out!
According to the FL Building Code, only synthetic and felt needs to overlap 50% plus the few inch manufacturer lap, while peel and stick only requires a few inches as required by the manufacturer.

I feel like that would render it useless. We deal with ice damming where I roof . And if the ice and water shield wasn't fused to the sheathing it wouldn't protect the home from ice damming backing up the shingles

I was told by my roofer that he only recommends peel and stick on something called the valleys. And that peel and stick melts in the heat. However another roofer said...if they use a HIGH PERFORMANCE Peel and Stick...the heat and sticking does not. Whats the difference?
directorii.com/category/roofing/ try this link it was created by one of the most credible roofing platforms known as Roofing Insights. I would recommend searching here for a roof!
I like what you are saying but here in Tampa Bay I talked to about 10 companies and they all insist on peel and stick. Also they all said when it is time to reroof you leave it down and cover with felt. Inspectors in my county have no issue with this although it may vary depending where you live.
Peel and stick is fine, just not direct to deck. In the Florida heat, the peel and stick will meld to your decking. If you get a roof replacement down the road and the company cannot get the Peel and Stick off the decking then unfortunately they may have to remove the decking and re do it which can cost you more money!
@@eustisroofingcompany As long as wood is good there is no need to remove it or the old peel and stick. But that only applies to my county. Def worth investigating ahead of time.

This is backwards, put the peel and stick directly to the wood, because that is how it is intended to be installed and do a synthetic underlayment over the peel and stick, this way the peel and stick is install properly and the shingles dont stick to the peel and stick. Peel and stick on top defeats the whole purpose of even using peel and stick. Im just a handyman 🤷♂️
The company has a strange nabw, it sounded like he said "This is how you know this is a useless roofing job"! RUclips even translates it to useless when CC is turned on.
peel and stick has to be put directly to the decking. When its done you should either put synthetic overtop, or just get the type of peel and stick that isn't granulated. putting synthetic over top of the peel and stick is useless. Should be the other way around. When it comes time to re do the roof, you will still be able to pull the synthetic off and shingles as normal. Stop trying to sell out what's easier for you to do when its not the best way of doing it. Laying peel and stick is way harder to lay out, especially in hotter temperatures.
Hey Josh We love to see feedback from roofers. So here is some reason why not to install peel and stick to the wood deck when installing shingles. First of all, this is when roofers peel and stick the entire roof. If it is a small problematic area, I think it's a good solution. In my area, the wood has to be inspected by the city or county inspectors. So when you peel and stick, and it melts to the wood, they cannot inspect the wood. In some cases, they make the homeowner re-deck the entire house. So obviously, this is expensive for the homeowner. Another requirement for inspection is to re-nail the decking. Our codes require every 6 inches, and we have to have it inspected. So if you peel and stick the entire roof, you can not visibly see the nails and in the roof truss to re-nail the decking to code. We are thinking long-term. So it's the next roof you get as a homeowner; you don't run into these problems. Also, you mention using granular peel and stick, and shingles won't melt. We have seen them melt to that type of peel in stick several times now. The only roofs shingles that have not melted are the high temp peel and sticks. If you look at Miami, Dade inspections, they required nailable underlayment under the peel and stick. Miami Dade is the toughest inspection requirement in the country. They made this change years ago because they were having the same issues as I described above. When you install a nailable underlayment first, you can remove and follow the inspection processes in my location. You also won't acquire extra expenses in the long run as a homeowner. It depends on your location and inspection processes. - Jason
@@eustisroofingcompany I said that if you don't want the shingles to stick and don't want to go over it with a synthetic to use the non granulated peel and stick/ice and water. Dont see how there would be a problem re nailing the plywood down if it wasn't installed correctly and getting it inspected as rafters aren't just randomly placed on the roof, they're every 16 or 24 inches apart. Find one and measure that over and bam in the middle of a rafter. But I get what you're saying, unless it's done with the high temp peel and stick, its always problematic down the road. But then again more expensive types of shingles, whether it be the plastic type, or just designer shingles. Are usually being done on homes that costs millions and the homeowner doesn't typically cheap out.
Why use peel and stick over synthetic. It seems like the most important layer is the bass that should be bonded to the plywood . If wind from the hurricane gets up under the synthetic it will all peel up and then you’re screwed. If the peel and stick stuck to the plywood the house will never leak. This is why we do it here in Fort Myers Florida.
@@chalmerelkins8965 thats what im saying. Peel and stick is obviously better than synthetic but should be used on the entire decking when it comes to metal or higher end jobs or ehen certain roofs need the entire deck like a 4/12 and so on
That's not peel and stick that's 30 lb felt paper over the 1 x 12 decking that house is 50 years old and it looks like the shingles were nailed with one inch nails wrong
No sir, it is indeed peel and stick on an 8 year old roof. Notice there are no simplexes holding it. If it were felt it would have to be nailed to stick to the deck. Also thats plywood, not 1 x 12 and the apartment was 28 years old
If a metal roof is installed correctly, including from the decking to the final install with the correct materials it can last a lifetime. It may require maintenance, as all roofs do but the correct install will be the last roof that house would need (barring any weather acts of God occurances).
@@cherylreisman8857 yes, CAN. But it's still a 50 year roof, same as tile. And there's 50-year shingles too. Usually by 'lifetime', one is thinking of how many years they will live, and that the roof will last 'their' lifetime that they have remaining. With a metal roof, the rubber washers on the screws are the weak point.

Wouldn't that make it not work ? Peel and stick is supposed to " stick " to the deck I thought . If ice backs up and it's not fused to rhe deck it can still leak
We respect all roofers - whether subs or in-house crews. There are plenty of amazing subs out there. My point is roofing contractors that just hire subs for install without proper training to their company expectation and standards. Additionally the roofing contractor gives risk to the sub to provide their own insurance. If the sub isn't licensed in the State of FL their liability won't cover the claim for the homeowner. There are plenty of great sub crews out there but we can do a better job by bringing them in as part of the team. There's a seperation with team effort and all working together for the same goal as a company when you just hire a sub crew as well as providing consistent quality work as a company on a whole for the homeowners.
@DEAROTNUF Good point! Wrapped vehicles doesn't always mean great workmanship. Evolving and changing to better branding resignates that the company is professional and cares about their image. it also creates more of a team feeling creating pride and qulaity workmanship. Our goal is to bring information to the homeowner for the homeowner to make the best decision on the roofing contractor they hire.

Synthetic underlayment over peel and stick so this doesn't happen. It's common sense that most roofers don't have or flat out don't give a s#!t about the next guy.

Yep I’ve already experienced one that 1st gen peel and stick stuck to deck and shingles stuck to peel and stick and had to replace all 140 sheets of plywood but when roof was done it was before renail code so the only way to meet code was to replace the deck but luckily it was a insurance claim so everything was covered under the policy under the old rules , I’m sure under the new rules might be a different story 💸😆
Then I got to test out newer generation peel and stick on another house that was replaced due to a tree falling on house the first go around everything was going well then 3 years later another tree fell on the house and no shingles stuck to peel and stick , both roof replacements were insurance claims so homeowners didn’t care how much roof was , now she has 2 layers of peel and stick protection
Can it hold on galvanized roof? Does it need to be replaced after a while?
@@Rican431need more details from your question
@@jaredconte3418 what do you need to know?
Om in Fl., looking at a new roof.
I have a couple bids that are using Perl and Stick OVER Plywood Decking.
Are u saying, it's GOOD to use these days, because thats a question I had for the Roofer.
Question: What about a follow up if needed, a tear off, will the Peel and Stick cause a problem?
His answer wasn't clear, he was the salesman for the local Roof Company????
I remember his answer.
After tear off, go back over the original Peel and Stick with New Underlayment?
Now, I came back and said, that be all good if the Shingles came off clean??
Up North we are required to put Iceguard (peel and stick) 24 inches past inside of warm Interior wall directly to deck along eaves . If I was down south I would agree with you. I know metro Dade standards are high.Up here there are no nail I inspections etc. Ofcourse we don't have hurricanes etc. What we do have is a lot of ice in the winter. I appreciate the quality and care of your work. To many hacks out there.
Yeah roofing varies depending on where you live and the type of surrounding environment. We appreciate the comment and support!
Everything I wanna learn about anything is on RUclips. This makes serious sense.
Thanks for the encouragement!
In South Florida they put 30 lb underlayment down first. Then peel and stick on that. Never direct to wood. That's with a cement tile roof.
Hey!
Do you guys run peel and stick in the valleys first and then put metal on top?
I am in a high debate with an installer!
I am used to putting peeling stick on the deck and then nailing my valley metal over it and sealing over the nails.
He swears that it is best to put the metal down, and then the peeling stick on top and into a degree I do agree with him, because in theory, it would take the sharp edges out of the wood and give the pill and stick and ice flat surface to lay on.
I look forward to hearing from you guys!
I did not read all comments. But ice and water stuck to synthetic underlayment. Does that improve anything???? What do I miss? .
I tore a roof off in Daytona Beach that had peel n stick as the underlayment and didn't have this problem.
Existing roof is near flat (maybe 1/8” in 12”) so we are planning to add tapered polyiso - about 1” to 7” with 1/2” plywood cover which will also help to match slope on adjacent new patio roof. The plywood will be screwed through the insulation to the existing 1x6 t&g deck
Should we use nail down underlayment with peel and stick cap sheet vs peel & stick underlayment or direct peel & stick to the plywood?
This is a great question. Yes, if you are attaching to wood, I would use the nail base provided by the manufacturer. CertainTeed makes a low-slope roof system that is three-ply, and I highly recommend it. The first layer is their nail base, the second is base self-adhered, and the third is their cap sheet, which is the final product. If you follow this method, you can remove the roof in the future for replacement. It's a very solid roof system. The key to this is to stagger each layer so the seams don't stack up.
Jason R
Or you can put synthetic over ice and water. And what's the difference from ice and water or synthetic as to trapping heat and shingles not lasting as long? Won't both trap just as much heat?
Recently we have removed roofs that had peel and stick directly to deck and have noticed a consistency of the shingles not lasting as long. I will always recommend placing synthetics down before just for the purpose of removal of the roof in the future.
@@eustisroofingcompany I'm in central florida doing my own roof. Do you recommend synthetic underlayment on deck and peel and stick over it? Or peel and stick on decking and synthetic over peel and stick? I'm thinking for the future if I need to replace my roof again and don't want the issues from the peel and stick not being easy to remove.

What the name of the blue underlayment product? Same as the roof felt ASTM? I am here in San Diego
This blue underlayment is in the video is CertainTeed's RoofRunner Synthetic underlayment.
Do you put peel and stick underlayment under tile roof since it can break?
I'm from BIG ice dam country. Ice & Water shield has to go down on the plywood deck or it's worthless. Then install your felt or synthetic over the entire roof. That roof looked like it was an old house that had 1x12 plank sheathing. In that case it needs new 7/16 osb over that. I have a clause in my contract for bad underlayment. Peal and stick also needs to go in the valleys on the plywood. You put that down early in the morning. Before the temperature rises. I do high end roofs.
I live in NY. I had a Liberty installed directly to the wood. My roof is low slope. What are my options for reroofing?
Liberty is a good product . Low slope roof you have some different options than your typical slope roof. On your next roof you can install insulation board or cover board over your liberty if it won't come off. I wouldn't worry about it plus you're in a colder environment than FL. We get extreme heat which causes more concerns with peel and stick. My concern is when peel and stick and Shingles melt together and it cost the homeowner more money to remove .
I'm in NY and planning to do liberty. Manufacturer want direct to deck but I'm concerned about when it comes time to reroof. What would you do and use?
Yea I dont have issues with the currect roof that people are pointing out no buckling etc. It looks real nice. But it is 12 years old and I know in the next couple years I will have to do something. I dont know how long they last. @@eustisroofingcompany Also just asking but can you put three tab over the existing Liberty??
@@StephenCunningham1 You are absolutely right to be concerned when it comes time for a reroof, people don't think that far out and is the root of the issue, it all depends on what type of roof it is and pitch it is. However first and foremost always follow local code and regulations.
I wonder if the older peel and stick has the same thing with melting to the shingles up in the Northern States where it does not get as hot or hot for as long as Florida does?
When the hurricane takes off the shingles, the peel & stick will stop the rain from entering the walls and ceilings. Felt underlayment will blow off with the shingles. Once the hurricane winds blow off the shingles, it continues to rain for hours.
Peel and stick will then become the primary membrane and protect the home from water intrusion. Difficult decision, but just dont say you should never do it.
We always put the peel and stick over a synthetic underlayment. Not directly to the wood deck.
Putting a self adheard product is far better then not, but you must ventilate properly and you mus put the correct peel and stick down, high temp tile underlayment which is more expensiev, as in polyglass mts polyglass xfr etc. With that said if shingles do blow off the self adheard secondary water barrier wil prevent water inrusion, in addition to getting an additional insurance discount! Synthetetic undrlayment is not water tight unless shingles are installed the same day, been there done that.
@harringtonsonsinc.2097 I was told ...as long as it's a HIGH TEMP Peel and Stick you should opt for it.

Up here in the Jacksonville area, thanks for your info, I thought that was the case with peel and stick, that is sticks always to the roof decking, so I won't do that, you saved me lots of time, trouble and money.
Stay safe!
I live in southern California. We have a 3400 SF house with concrete tile roof. What type of underlayment would be a good choice? We are thinking to upgrade the underlayment from felt to titanium synthetic UDL 50. Is this a good choice or should we stick with double layer 30 pound felt. Some of the local roofers do not recommend synthetic underlayment for tile. I appreciate your input!!!
Install the UDL50 .Awesome material.
SO I READ EVER COMMENT AND DEBATE. SO ESSENTIALLY ARE YOU SAYING IF I OPT FOR PEEL & STICK. BE SURE TO USE THE "HIGH TEMPERATURE" PEEL & STICK VS THE STANDARD TYPE. ? Plz correct me if I am wrong
I always recommend the high-temp peel and stick. I love every form of peel and stick. However, if you ever attach directly to the deck, I prefer high temp. This also depends on proper ventilation and if it meets code for the final roof product that gets installed. I have seen peel and stick fail and drip around the house, which is a huge mess. I have never witnessed the high temp doing this. It's a superior product and much thicker. I always recommend high temp with metal roofing and other high-end roofing products that last much longer than shingles.

When you install ice and water shield on the plywood just remember to install the synthetic underlayment over the ice shield so the shingles won't stick.
I think the guy said to install the peel & stick over the synthetic underlayment so the peel & stick doesn't stick to the plywood causing a mess the next time they're removed. The peel & stick sticking to the shingles is not a problem.

Is Boral Tile seal considered a peel and stick product?
No, Boral Tile seal is not a peel and stick product. Boral Tile seal is a type of sealant used for sealing and protecting tiles. It is typically applied using a brush or roller to create a protective barrier on the surface of the tiles. Peel and stick products, on the other hand, usually refer to self-adhesive materials that can be easily applied by peeling off a backing and sticking them onto a surface.
Boral Tile seal is an approved peel and stick underlayment manufactured by a tile manufacturer.

Torch used direct on wood sheathing to soften snow and ice guard might not be a be a good idea. Or.....maybe the best idea if you have incredible insurance.
Hey Jason, I understand your concern with peel-n-stick for the shingles roof. But what about a tile roof in FL? Would you recommend the same (nailable underlayment under the peel and stick) for a tile roof? Or directly over the decking? Thanks!
Great question! Direct to deck is best as tile lasts significantly longer than shingles as well as not effected by heat like a shingle install. Metal & tile installs are best to go with a High Temp Peel & stick right to the deck.
Only the older peel and stick will stick to the shingles. The current peel and stick no longer sticks to the shingles, because the manufacturers are aware of that and that problem has been fixed. Plywood roof deck is an organic material which requires only 1 side to breathe. As long as you don't block the bottom side of the wood deck from breathing from something like spray foam, you will be safe to install peel and stick directly to the wood deck. Putting synthetic underlayment first to the wood deck will NOT allow breathing between the peel and stick and the wood deck as described in this video. Also it's very important to keep in mind that peel and stick has little adhesion to felt paper and better adhesion to synthetic underlayment, but peel and stick has a much stronger pull strength than synthetic and felt! So if your shingles blow off then, hope and pray that your peel and stick won't blow off the underlayment. All shingle manufacturers state that they require ventilation from the eaves to the attic vents and they don't mention any warranty issues when you put peel and stick directly to the wood deck.

Ugh I am perplexed. What you are saying makes sense because the peel and stick or ice shield is going to bond to the sheathing. I am a house flipper. I was a contractor up North and did some roofing but live in sw Florida now. Im getting bids on a roof right now and everyone is bidding peel and stick to the sheathing. The last house I did we used synthetic underlayment and no peel and stick. The insurance companies gave the buyer a hard time about it. Some comment below saying that using the synthetic first is not ok with codes or manufactures so I am now totaly confused.

Why not put the peel and stick on the roof deck, then a layer of synthetic underlayment, then shingles? Look forward to your answer.
There are so many unsolved issues and code requirements in the entire peel-and-stick argument; it's kind of a mess. My main concern is that when the roof gets removed, it could be extremely time-consuming to renail the deck if needed. Additionally, we have personally seen peel-and-stick fail, causing tar to drip from homeowners' roofs into the soffit and around the house. So, I always want a way to remove it if possible. I think your point is good and is better than going directly to the deck. The issue seems to be long-term, and listening to the roofers who have seen huge problems, one of the biggest issues was shingles melting to peel-and-stick and peel-and-stick melting to the deck. Your way solves that. With that said, I am a huge fan of peel-and-stick; I just want to look out for the future and make sure it doesn't affect the homeowner in a negative way. Jason
thank u!!
I have experienced this as well in NE Florida and I have been skeptical to use peel and stick direct to deck for the reasons you mentioned, plus I have seen it buckle on our roofs and roofs that other roofers have done. I have asked a couple manufacturers about using synthetic as a slip sheet and they have said they don't have approval for peel and stick over synthetic, but you can use traditional felt under peel and stick. Am I getting bad information or is there a peel and stick that you use that has an approval to be used over synthetic?
Your question is great. There is a lot of testing being done to investigate the effects of peel and stick application directly onto the deck. If you choose to install over synthetic materials, I recommend following the synthetic dry-in codes and using a 2-ply system. This way, the peel and stick will provide added protection and you will avoid issues with codes.

You are a justice roofer.
I was told by a metal roofing material vendor that the peel and stick had to over lap 50% say 36 in width role needs to over lap by 18in here in Florida is that true?
This is true when it comes to synthetic underlayment. Some counties require 17 1/2" to be exact for 50% overlap. Peel and stick isn't required to be half lapped, only synthetic. This is all dependent on the county you're in. There is one county that requires 50% overlap because of the type of peel and stick. Half the lap of the peel and stick is nails and gets peel and sticked over. They do this so that the peel and stick isn't direct to the deck like in the video, if you have any other questions don't be afraid to reach out!
According to the FL Building Code, only synthetic and felt needs to overlap 50% plus the few inch manufacturer lap, while peel and stick only requires a few inches as required by the manufacturer.

I feel like that would render it useless. We deal with ice damming where I roof . And if the ice and water shield wasn't fused to the sheathing it wouldn't protect the home from ice damming backing up the shingles

I was told by my roofer that he only recommends peel and stick on something called the valleys. And that peel and stick melts in the heat. However another roofer said...if they use a HIGH PERFORMANCE Peel and Stick...the heat and sticking does not. Whats the difference?
I live in wauchula fl. Any fellow roofing companies Eustis roofing would recommend for a metal roofing install on an old home.
directorii.com/category/roofing/ try this link it was created by one of the most credible roofing platforms known as Roofing Insights. I would recommend searching here for a roof!
I like what you are saying but here in Tampa Bay I talked to about 10 companies and they all insist on peel and stick. Also they all said when it is time to reroof you leave it down and cover with felt. Inspectors in my county have no issue with this although it may vary depending where you live.
Peel and stick is fine, just not direct to deck. In the Florida heat, the peel and stick will meld to your decking. If you get a roof replacement down the road and the company cannot get the Peel and Stick off the decking then unfortunately they may have to remove the decking and re do it which can cost you more money!
@@eustisroofingcompany As long as wood is good there is no need to remove it or the old peel and stick. But that only applies to my county. Def worth investigating ahead of time.

Thanks Jared this is helpful. I ended up have the peel and stick applied to the wood plank decking. As you advised I will not get spray foam insulation like my neighbors. @@jaredconte3418
Noting wrong with using subcontractors, ours a freaking amazing!
Insurance companies require for the peel & stick to stick to the plywood for your homeowner to read the benefits of a discount

Smart
This is backwards, put the peel and stick directly to the wood, because that is how it is intended to be installed and do a synthetic underlayment over the peel and stick, this way the peel and stick is install properly and the shingles dont stick to the peel and stick.
Peel and stick on top defeats the whole purpose of even using peel and stick.
Im just a handyman 🤷♂️
The company has a strange nabw, it sounded like he said "This is how you know this is a useless roofing job"! RUclips even translates it to useless when CC is turned on.
peel and stick has to be put directly to the decking. When its done you should either put synthetic overtop, or just get the type of peel and stick that isn't granulated.
putting synthetic over top of the peel and stick is useless. Should be the other way around. When it comes time to re do the roof, you will still be able to pull the synthetic off and shingles as normal.
Stop trying to sell out what's easier for you to do when its not the best way of doing it. Laying peel and stick is way harder to lay out, especially in hotter temperatures.
Hey Josh
We love to see feedback from roofers. So here is some reason why not to install peel and stick to the wood deck when installing shingles. First of all, this is when roofers peel and stick the entire roof. If it is a small problematic area, I think it's a good solution. In my area, the wood has to be inspected by the city or county inspectors. So when you peel and stick, and it melts to the wood, they cannot inspect the wood. In some cases, they make the homeowner re-deck the entire house. So obviously, this is expensive for the homeowner. Another requirement for inspection is to re-nail the decking. Our codes require every 6 inches, and we have to have it inspected. So if you peel and stick the entire roof, you can not visibly see the nails and in the roof truss to re-nail the decking to code. We are thinking long-term. So it's the next roof you get as a homeowner; you don't run into these problems. Also, you mention using granular peel and stick, and shingles won't melt. We have seen them melt to that type of peel in stick several times now. The only roofs shingles that have not melted are the high temp peel and sticks. If you look at Miami, Dade inspections, they required nailable underlayment under the peel and stick. Miami Dade is the toughest inspection requirement in the country. They made this change years ago because they were having the same issues as I described above. When you install a nailable underlayment first, you can remove and follow the inspection processes in my location. You also won't acquire extra expenses in the long run as a homeowner. It depends on your location and inspection processes.

@@eustisroofingcompany I said that if you don't want the shingles to stick and don't want to go over it with a synthetic to use the non granulated peel and stick/ice and water.
Dont see how there would be a problem re nailing the plywood down if it wasn't installed correctly and getting it inspected as rafters aren't just randomly placed on the roof, they're every 16 or 24 inches apart. Find one and measure that over and bam in the middle of a rafter.
But I get what you're saying, unless it's done with the high temp peel and stick, its always problematic down the road. But then again more expensive types of shingles, whether it be the plastic type, or just designer shingles. Are usually being done on homes that costs millions and the homeowner doesn't typically cheap out.
You mean don't put peel n stick over synthetic
Why use peel and stick over synthetic. It seems like the most important layer is the bass that should be bonded to the plywood . If wind from the hurricane gets up under the synthetic it will all peel up and then you’re screwed. If the peel and stick stuck to the plywood the house will never leak. This is why we do it here in Fort Myers Florida.
@@chalmerelkins8965 thats what im saying. Peel and stick is obviously better than synthetic but should be used on the entire decking when it comes to metal or higher end jobs or ehen certain roofs need the entire deck like a 4/12 and so on
That's not peel and stick that's 30 lb felt paper over the 1 x 12 decking that house is 50 years old and it looks like the shingles were nailed with one inch nails wrong
No sir, it is indeed peel and stick on an 8 year old roof. Notice there are no simplexes holding it. If it were felt it would have to be nailed to stick to the deck. Also thats plywood, not 1 x 12 and the apartment was 28 years old
Metal rooves aren't lifetime.
If a metal roof is installed correctly, including from the decking to the final install with the correct materials it can last a lifetime. It may require maintenance, as all roofs do but the correct install will be the last roof that house would need (barring any weather acts of God occurances).
@@cherylreisman8857 yes, CAN. But it's still a 50 year roof, same as tile. And there's 50-year shingles too.
Usually by 'lifetime', one is thinking of how many years they will live, and that the roof will last 'their' lifetime that they have remaining. With a metal roof, the rubber washers on the screws are the weak point.

Wouldn't that make it not work ? Peel and stick is supposed to " stick " to the deck I thought . If ice backs up and it's not fused to rhe deck it can still leak
I recommend following the synthetic dry-in codes and using a 2-ply system. This way, the peel and stick will provide added beneficial protection.
This dude making it sound like sub contractors are a bad thing or something.
We respect all roofers - whether subs or in-house crews. There are plenty of amazing subs out there. My point is roofing contractors that just hire subs for install without proper training to their company expectation and standards. Additionally the roofing contractor gives risk to the sub to provide their own insurance. If the sub isn't licensed in the State of FL their liability won't cover the claim for the homeowner. There are plenty of great sub crews out there but we can do a better job by bringing them in as part of the team. There's a seperation with team effort and all working together for the same goal as a company when you just hire a sub crew as well as providing consistent quality work as a company on a whole for the homeowners.
@DEAROTNUF Good point! Wrapped vehicles doesn't always mean great workmanship. Evolving and changing to better branding resignates that the company is professional and cares about their image. it also creates more of a team feeling creating pride and qulaity workmanship. Our goal is to bring information to the homeowner for the homeowner to make the best decision on the roofing contractor they hire.

Synthetic underlayment over peel and stick so this doesn't happen. It's common sense that most roofers don't have or flat out don't give a s#!t about the next guy.
