For drip edge, do you nail the overlapping joint or don’t nail it for the edging to expand and contract?
I know you don’t nail the overlap with W-valley metals. When I removed the old valley metals, the top edge was flattened and bended over the ridge. Do I do the same for the new valley metals?
What about the end of the valley metal at the drip edge or gutter, leave it or flatten it out? I don’t recall how the original one was and I have already threw the old ones away.
Thank you for your help.
