How far should shingles hang over gutters?
1/4 to 3/8 inch
Most shingle manufacturers recommend a 1/4 to 3/8 inch overhang over your eave, which is where your roof ends by your gutter. In many cases, and particularly as home ages and settles, the roof edge at the eave edge can wave in and out by more than this amount.
How far should shingles extend past drip edge?
