How Much Should A Shingle Hang Over The Roof Edge

Too little can allow water to seep into rake or fascia boards.

How much should a shingle hang over the roof edge.

Getting your overhang installed correctly is essential but what does that mean. Too much overhang and the shingles could blow off in high winds. Ed the roofer if what you say about fixing the problem cutting the edge is the proper way to do it than i m not terribly upset. I was worried that because the edge shingle is the bottom layer fixing this would require redoing it.

We ve seen other references that suggest extending the shingles a bit more than the manufacturers suggest to compensate for wavy eaves but they do not indicate extending more than 1 inch over the eave. 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. Nail high up on the drip edge so that the shingles will cover the nails. In my opinion the felt underlayment should also extend beyond the drip edge by 1 4 to 1 2 inch.

The 3 4 overhang of the shingle creates a full 1 overhang from the fascia to the edge of the shingle. Knowledgeable roofers will install shingles at just the right overhang for your roof type. Don t overdo the overhang shingles that extend more than 3 4 inch can eventually bend and fracture leaving the roof sheathing and fascia vulnerable to water damage. The edge of the shingles should hang over a 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.

Shingle manufacturers say to use a 1 4 to 3 8 inch shingle overhang over the eave where your roof ends. The overhang of roof shingles is the amount of the shingle that extends past the lower edge of the roof creating a lip. Ideally you d nail about every 12 inches and in no circumstances should you have 16 inches or more between nails. Why is overhang important.
