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.

Most shingle manufacturers along with the asphalt roofing manufacturers association s residential asphalt roofing manual call for a 1 4 inch to 3 4 inch overhang at both rakes and eaves. The length of the overhang itself commonly ranges from 2 to 5 inches. 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 will protect a roof from most types of damage. In my opinion the felt underlayment should also extend beyond the drip edge by 1 4 to 1 2 inch. Knowledgeable roofers will install shingles at just the right overhang for your roof type. Roof drip edges are generally sold in 10 5 foot lengths but they are occasionally sold in 8 foot lengths or smaller.

This profile of drip edge is shaped like a t with a lower flange at the bottom. Each has their own reasoning for a slightly different amount of overhang. How much overhang should roof shingles have. If you have installed a drip edge flashing you should have between half an inch and three quarters of an inch of shingle overhang.

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.
