comp roof install

From a distance If you dont see valley flashing on comp roof just comp instead is this a sign there is none under shingles or there is flashing underneath . I see this in some new construction.

If you don’t see it you can’t report on it.

Here is a video on 3 differnt methods of installing valleys.

Valley flashing is not required in all (most) areas and as Larry pointed out there are several methods of closing in a valley with compositional shingles.



Thanks all i appreciate it
