How far should shingles hang over gutters?
1/4 to 3/8 inch

How far should shingles overhang?
Shingles should not extend more than 3/4” (19 mm) past the drip edge. If shingles overhang the edge of the roof by more than 3/4” (19 mm), then they are not supported and may crack and break off. In addition, the wind resistance at the roof edge may be compromised.
