Long-time lurker. Full disclosure I am rarely the boots-on-the roof. I organize and hire crews and deal with customer issues and smaller repairs where a whole crew is unnecessary.
I have a a situation with a customer and a crew and would like some input.
Roof is a 4 hip with standard ridge. Crew ran Timbertex hip shingles up like normal and added an extra cap shingle nailed down over the joint between hip and ridge with a split in it and cemented. Used washer shank nails to secure.
I know this is very common practice where we are but it certainly doesn’t look like the perfect “display model” on the GAF website. In a " by-the book" install we wouldn’t have the extra shingle but would just lay a cap over the ridge and there would be a bit of visible joint at the butt end. As it is there is coverage from 3 shingles under the split and the extra is just to help hold it
Customer says he spoke to GAF by email and was told this was a bad Install, but won’t forward that email.
Of course I’m just getting this info now, when it’s after hours and I can’t reach GAF until morning.
I’m willing to believe that my guys and I all learned from the same backwards country teachers, except we’ve never had leaks doing it this way. In fact customer isn’t complaining about any water penetration, just cosmetic dislike (and of course he’s demanding a GAF rep inspect his whole roof and wants a big discount)
So what say you give mind, is it total crap and we need to stop immediately or is it unusual but not risky? As I said the issue isn’t leaks, and no leaks in the past, I’m competing with something GAF allegedly told customer and have nothing else to go on - which is driving me nuts.
