Hi - During a recent storm I noticed the patio roof (low-pitch, roll roofing) was dripping quite a bit despite the presence of a gutter and downspout. Climbing the ladder revealed that there is no drip edge installed.
(As an aside, I feel a little silly because this was noted in the inspection, I asked for a repair and then approved when I saw they had installed it along the pitched ends of the roof. It hadn't occurred to me that the edge with the gutter would need one too.)
It looks like the roll roofing was installed to hang an inch over the gutters, but of course, that's not how water works and it has been coming back under, soaking the OSB and running down the fascia board.
I feel pretty confident I can handle this install, but I have some questions (based on the photos below): Should the drip edge be installed a) flush with the existing roll roof edge, b) flush with the OSB sheathing, c) just as long as it's over the gutter who cares? If the answer is "b", should I cut the roofing material back to be flush or create a specific overhang? As you can see from the photos, there is a line of nails right at the edge that will need to be removed for installation of the drip edge. Do I reinstall those when finished, or use some other form of fastener or adhesive?
Anything else I'm missing?
Thanks in advance!
