First, yes, I did try to Google this.
What should the typical overhang that a shingle should have into a gutter? (This is going to get a lot of "different" reponses.)
I had noticed that in one section of my roof I was getting a lot of water dripping down, almost like a leak. I borrowed a ladder from a neighbor to check this out. Overhang of shingle at the area in question was less that 1/4in.
I know that there are some construction minded folks here. Any help?
