Paint like coatings have been around for a long time claiming to extend the life of your roof for years. Until the late 90's they actually didn't do much more than camouflage a dying leaking roof -- the problem being that things move up there from full sunlight to cold nights, from hot summers t...
Getting something to stick to asphalt or asphalt coated materials is a unique problem. Asphalt driveways have their own specific crack sealers and roofing materials generally use what we call "Plastic Cement". (One exception to this is a specially formulated polyurethane adhesive that will work...

"I would like to ask your thoughts on the "pros and cons" on the use of the self-adhesive, 3 ft wide membrane (ice dam) used on the edge of the roof line. I believe that this would replace the felt paper, under the 1st rows of asphalt shingle. We have a sloped roof, but I do not know how ste...
