Are you familiar with Duck Coat Roof Coating??

John, thanks for that detailed answer! I don't have a leak, and my roof looks fine -- but I am one of those "be prepared" folks, so I am doing my homework ahead of time.

And the fact that Duck Coat does not have data sheets is not encouraging. I will keep on going with my research.

In my dreams, there is some sort of an easy to use, pour-on roof coating that dries quickly.

I guess that as I have gotten older, my dreams have become much less interesting than they were when I was young! ;)
