They took most of the debris with them. (They left a couple rolls of nails and about 20 packs work of cigarette butts), so I can’t say what was used for frost/water protection underneath the shingles. I’ll ask the owner today when I meet him, though, exactly what they did for that 3’ from the edge.
Well, if GAF says 1/2" from the drip-edge, I take that as gospel. Anyone know where I can find documentation? I’d like to print something up for the contractor in-case he disagrees.
To be honest, the fact that I can’t get my hand in the gutter without a glove is about all I need, at this point, in my humble, non-professional-roofer opinion.
I’ll let you know how it all turns-out and close this thread. Thanks to everyone for the opinions and discussion about my problem. I makes me much more confident when I deal with the contractor now.
