Put it on a flat roof to seal it. Time will tell. We have one small area which we have to touch up but no other leaks during our last heavy rain fall.

Easy to apply and dries fast. Be aware that it is not uv rated so you have to cover it with something, I just painted it with white latex paint. I do have some cracks that formed but I think it was because it was exposed to freezing temperatures. I used it on my rv roof and have had no leaks. Good product.
