Hello.... Today I just discovered some roof rot due to sub-standard installation of some Sheriff-Goslin T-lock shingles. The company says that had I found this inside of 10 years the materials and labor would have been free, but now I have no recourse except to foot the bill for repairs myself. I'll get to the specific installation errors in a second.
I write for two reasons:
(1) does anyone know anything about "after discovered defects", where a person had no reason to know of negligence until a problem shows up after a warranty expires?
(2) any roofers have advice how best to repair the problem, short of reroofing the whole place?
OK.... first, I'll describe the place and the problem. The job was a roof-over and is about 14 years old. The back of the house has an attached unfinished shed. The roof sheathing is 1x pine. There is a measly 2" soffit. So.... along the eave, the lowest of these pine boards is partially above the wall framing and partially cantilevers out a short way. Or at least it used to do that. The part that cantilevers out is pretty much gone.
As a result, just above the wall framing the shingles are no longer supported, and so they are forming depressions like a lake bed, all poisted to cause backup runoff to get to the back of my new hardiplank siding.
The shingles themselves are in fine shape.
The installation errors are: (A) Rake drip edge was tucked inside fascia drip edge, and (B) on the rakes, the underlayment used in the roof-over does not lap the additional drip edge.
Thanks for any thoughts about the negligence angle, or ideas for adequate repair.
