Hi. I hope I’ve to the right place for some practical advice. I’m having a roof done. During a work break, I went up the ladder to have a casual look at the job in progress. I noticed a nail directly under a butt joint. (The shingles had not yet stuck together, so the nail was visible from the angle I was at.) This seemed unusual to me - “can’t that leak ?” This was from just inspecting a small portion of the roof that I could see from the top of the ladder (I did not get up on the roof), so I suspect there are more nails under other butt joints.
From other perusing online it seems nails under the butt joint can be a source of leakage. I’d really appreciate any constructive advice about how to deal with this now with my roofer. The job is pretty much done now. Any comments on the leakage risk ? Should I ask the roofer to inspect each of the butt joints, and remove any nails and seal them with something ? (not sure if that is practical).
If it helps, my roof is somewhere between 7/12 and 8/12.
