How much overhang for roof shingles.

The length of the overhang itself commonly ranges from 2 to 5 inches. 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. 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.

Position the side of hook knife against the drip edge beneath the shingle with the blade facing. Roof drip edges are generally sold in 10 5 foot lengths but they are occasionally sold in 8 foot lengths or smaller. Too much and the shingles can blow off. Too little overhang and the water can leak through into fascia boards.

Simply put this is faulty installation where the shingles extend too far over the edge of the roof or are too close to the edge. Too little can allow water to seep into rake or fascia boards. Knowing how much overhang roof shingles should have is only a small part of the job. There is a lot to know a lot to do and a whole lot to be carried.

After each shingle line has been laid one shingle will overhang the rake edge.
