One question that comes up a lot regarding Epilay’s Plystik Plus is whether or not it will cause problems in the future—usually the next time the roof needs to be replaced. For the most part, peel and stick underlayment shouldn’t cause you any issues, but let’s expand on this topic further so that you know what to expect!
Removing Peel and Stick Can Be Challenging
The need to remove peel and stick underlayment is the heart of the question when it comes to reroofing. Lots of contractors wonder if the material will need to be removed when installing a new roof. And, there’s no doubt about it—if you do have to remove peel and stick underlayment, it can be a tricky job because the adhesive is designed to stand up to the test of time. This means that the removal process will likely damage the OSB roof decking, so in most cases, if you do have to remove peel and stick, it is preferable to remove the OSB decking and replace that, as well.
But, Peel and Stick Doesn’t Usually Need to Be Removed
For the most part, however, removal simply isn’t necessary. When reroofing over peel and stick underlayment installed years prior, you can generally place a new underlayment right over top of the original peel and stick, then proceed with installing the new roof as normal. This is because peel and stick underlayments are designed to be a permanent installation, so when reinstalling over top of this type of underlayment, the major concern is covering over holes left by the fasteners that held down the original roof. The only time you should need to remove this type of underlayment is if it has been severely damaged or if the deck beneath it needs to be replaced anyway.
Actually, one of the largest advantages to peel and stick underlayment is that it typically lays flatter on the roof deck than non-adhesive underlayments. This means that when it comes to installing a new layer, you won’t have ripples or wrinkles to deal with, but instead, a nice, smooth surface, which lets you install a new underlayment on top of it with ease.
And there you have it. Yes, peel and stick removal can be a difficult process, but in most cases, you won’t have to remove it. So that means it shouldn’t give you difficulties during future roofing projects!
