I have a 6 layered roof of friends house I'm doing, it's a small crumbled patch. It was caused first by small leak unfixed that then this summer infested with ants. I stripped down the shingles, nailed a patch board, built it up the best I could, and tarred the valley. The question in all that is I have bumps? How do I take care of that?
