Roof coating over roll roofing on low pitch roof?
I have a large cape cod style dormer on the back of my house, with a very low pitch roof. It's currently covered in roll roofing, and I've noticed a couple fo small leaks develop this spring. I'd like to replace the entire house roof in a year or two, so I'd rather wait until then to replace the dormer's roof. Is it possible to cover a roll asphalt roof with some kind of roof coating to seal it for another year or 2? The roof is not visible from any angle, so looks are not important. If this is possible, what kind of coating should I use?
