Roof Overhang Calculator

FAQs

How do you calculate overhang length? The overhang length of a roof is typically measured from the exterior wall to the edge of the roof. To calculate it, you need to determine the desired overhang distance and subtract it from the length of the roof’s eave.

Why does 3 overhang occur? “3 overhang” refers to a roofing configuration where three courses of shingles extend past the drip edge. It is designed to provide adequate coverage and drainage for the roof.

What is meant by 5 overhang? “5 overhang” indicates that five courses of shingles extend beyond the drip edge on a roof. This provides added protection against water infiltration.
