Roof Tile Overhang

You will need to do this at the other end of the roof as well.

Roof tile overhang.

Your tiles will need a 1 inch overhang and the eave and a half inch head lug to the rear of your tile. 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. However for larger extensions you ll need to hire a professional to get up there and remove large portions of the roof before extending the overhang. Subtract 1 1 2 inches from your first mark and make another mark on the underlayment.

The fairly cheap and common shingle roofs that many people have are quite light. If you are transitioning from a light roof to a tile roof the weight difference will be substantial. With our house we are planning minimal east and west overhangs and ample south and north overhangs. We love the look of the no overhang scottish style roof line as well.

They are essential for framing and shading windows reducing splashback and getting rain to fall far enough away from the foundation. We will protect shade the west windows with cedar awnings grates. Too much overhang and the shingles could blow off in high winds. For a relatively average house with a 1 500 square foot roof the total of underlayment and tiles will equal something approaching 8 tons in weight.

Roof overhangs might look relatively routine but there is a lot of design thinking that goes into creating the optimal dimensions for each one. Doing so keeps basements and crawlspaces dry and it also helps to.
