The problem with peel and stick

General Manager Brian talks us through the issues that can arise from using peel and stick incorrectly.

If the last roof was installed after the code updated to require the current nailing pattern AND it passed inspection with the AHJ (easy to confirm), then it can be assumed. Otherwise, there must be a better solution that forcing thousands of dollars in new wood and labor.

On a new home, the decking will be nailed properly. The peel & stick (Self Adhered Membrane SAM) should be applied to the deck. A synthetic underlayment, or felt can be installed on TOP of the SAM so that the shingles can be removed/replaced in the future. Putting felt directly on the deck and under the SAM is a waste of time. The SAM applied directly to deck will protect the house after the shingles blow off. If there is felt under the SAM, it will blow away with the shingles. Not a problem, until you have a hurricane.

What about a strong magnet to check where the decking nails are? Or are there other problems besides the problem stated in the video of not being able to tell where the decking nails are?

I have never heard of taking something apart and replacing it to check nailing patterns. And putting peel and stick to felt paper does not make a whole lot of sense but code is code I guess..

[johnnyweld]

screws are better than nails guys thank you for uplift like for hurricanes thank you

[onelastproject]

You can literally check the nail pattern and nail size right through the attic.

Question, if you didn’t have the same problem on the front and could confirm the nailing, why would this side of the roof be any different? Hmm!!!

So in this video, was the peel and stick considered a secondary water barrier as it was applied on top of the felt? On average how much does a secondary water barrier cost, and is it necessary (I live in Central Florida and looking to replace the tile roof in next 1-2 years)?

[wyattburns]

Peel and stick has to be bonded directly to sheathing.this man has no clue what he is talking about ..done blame the material if your men didnt nail sheathing properly

[larrycrookshanks]

He might be correct in Florida but his points are completely useless in northern climates where ice and snow are the problem. Ice and water shield first and cover with synthetic felt.

[dllion]

That is an overkill. There are surely better ways.

[casade]

This makes NO sense!!!! This is some insurance nonsense going on 💁‍♂. Peel and stick on felt??? Sure, you can put on anything, but really? EDIT!!!! I just saw another roofer in Florida who puts the peel and stick on top of the felt too! I guess this isn't so stupid after all? What is going on here?

[jeffjohnson]

Your wrong. Go right over the old ice and water barrier rookie

[quebec]

peel n stick has to stick on wood thats common sense... why care about roofers that will tear it off in 25 years ? that's ridiculous
