How Much Overhang On Roof Shingles

In my opinion the shingles should never be exactly even with the edge of any drip edge flashing.

How much overhang on roof shingles.

Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports. Two feet is the general maximum length for a typical roof overhang. The length of the overhang itself commonly ranges from 2 to 5 inches. This will protect a roof from most types of damage.

The edge of the shingles should hang over the edge of the roof between an inch and an inch and a half or between a half inch and three quarters of an inch if drip edge flashing is installed and in most cases it should be. How much overhang should roof shingles have. If you do not have a drip edge flashing installed shingles should overhang an inch to an inch and a half. Knowledgeable roofers will install shingles at just the right overhang for your roof type.

A architect and roofing consultant harrison mccampbell responds. Anywhere from a 1 2 to a 1 overhang is acceptable as you can tell from the varying comments amongst the previous posters. This profile of drip edge is shaped like a t with a lower flange at the bottom. In my opinion the felt underlayment should also extend beyond the drip edge by 1 4 to 1 2 inch.

Each has their own reasoning for a slightly different amount of overhang.
