Thanks, Mike. This helps so much. I know they were cutting 3 tab shingles this morning for this purpose but can't tell what they used yesterday. One side of the house looks ok and the other side has shingle edges that appear ragged across the ridges and hips. I don't know if it was because there were different installers or if some used architectural and some used 3 tab shingles. If they did use 3 tab shingles all over (and we'll have to determine this) will they tend to smooth out as they are heated from the sun and become more pliable? Or should we insist that the supervisor who will be inspecting the project have the 3 tab shingles replaced with the accessory shingles if they were installed incorrectly? If they are replaced, will all the nail holes from the shingles there now need to be filled in? I know about toe boards and insisted that they not be used except as absolutely necessary. Also insisted that on the few that were used that the holes be filled in. The foreman said he'd never heard of anything like that!!! I've learned from the home inspectors as I attend all of my home inspections for properties in which I am involved as either the selling or listing agent. If they used 3 tab shingles and they were not aligned properly, can we ever expect them to be any better than what we're seeing right now?
