Question: Will this go over the existing layer or will I need to strip it?
Document: I bought a house with this product used as a liner for the rusted out metal box gutters. After having the house re-roofed, the membrane was looking a little ragged. After cleaning the existing membrane, I applied a spray on surface prep from my local supply company that made the surface tacky and ready for a new layer of peel and seal. It applied quick and easy and adhered tight after a good seam and surface rolling.
Peel & seal is very easy to work with, can be cut with a utility knife to the size you need. It sticks to just about anything that you need it to. I applied it to  my entire mobile home roof with very little effort, I have a older metal flat roof mobile home and it had sprung leaks over the years. and decided to put a new roof on. some of the estimates for a new roof were between $5,000.00 & $8,000.00.
Where it didn't seal perfectly, I used a heat gun to melt the asphalt adhesive to the metal of the trailer, and worked perfectly. For about $100 a square, I couldn't go wrong.
I tried this on recommendation of my roofer for a mobile home. We had to go back twice and heat with a heat gun just to get it to stick. After only a couple of months the leaks were back from seepage. I finally used a trowel grade fiber reinforced asphalt cement around all the edges to stop the leaks. The product is very thin and delicate and I would not recommend it. Better off to go with the cement and reinforcement tape.
I have used this product for years and it works great -- BUT -- you must clean then prime the areas that are going to receive this product first with an asphalt primer - this comes in a spray can or 5 gallon pail  -- light coat only - let it dry - then and only then put Peel-n-seal on. If you do not clean and prime the surface first I guarantee it will let go with-in 2 months - do it properly and it will last for years.
Peel and Seal is a great alternative to more expensive products for sound deadening and sealing a classic car. It is easy to cut and place and sticks good if the surface is very clean - use a product like brake cleaner spray. Makes applying carpet and padding a snap! Buying the bulk roll is the way to go.
I put this on a flat roof that had started leaking and it worked great! I put it right over the old rolled roofing with no problems.
I expect this repair will last at least that long. This is a good sturdy product that I would be comfortable using for other applications too, such as flashing.
Bought this to use as sound deadener in a car audio project. Have not installed it yet but I have reviewed the product - it looks great for my application. Was delivered very fast - was surprised when the UPS guy showed up just a couple of days after I ordered - and this was right before Christmas. Very satisfied.
I have an old RV that was leaking at the seams when water and snow built up on it. I was wary of installing a torched-on rubber roof due to the heat and cost. I found Peel & Seal, and it sounded like the perfect solution. Just spent a couple days last week prepping the roof and installing the Peel & Seal roofing, and I couldn't be happier.
