Roof Tile Overhang

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 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. Too much overhang and the shingles could blow off in high winds. With the west east overhangs the main use is siding window protection and keeping rain snow from foundation. Doing so keeps basements and crawlspaces dry and it also helps to.

Too little can allow water to seep into rake or fascia boards. 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. Roof overhangs might look relatively routine but there is a lot of design thinking that goes into creating the optimal dimensions for each one. Extending a gable roof can be tricky since it involves working on the roof but you may be able to do it yourself if you only need to add 1 2 2 inches 1 3 5 1 cm.

We love the look of the no overhang scottish style roof line as well. If you are transitioning from a light roof to a tile roof the weight difference will be substantial. The fairly cheap and common shingle roofs that many people have are quite light. 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.

We will protect shade the west windows with cedar awnings grates. With our house we are planning minimal east and west overhangs and ample south and north overhangs.
