Roof Tile Overhang

With our house we are planning minimal east and west overhangs and ample south and north overhangs.

Roof tile overhang.

We love the look of the no overhang scottish style roof line as well. Your tiles will need a 1 inch overhang and the eave and a half inch head lug to the rear of your tile. Subtract 1 1 2 inches from your first mark and make another mark on the underlayment. We will protect shade the west windows with cedar awnings grates.

Roof overhangs might look relatively routine but there is a lot of design thinking that goes into creating the optimal dimensions for each one. They are essential for framing and shading windows reducing splashback and getting rain to fall far enough away from the foundation. 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.

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. The fairly cheap and common shingle roofs that many people have are quite light. Too little can allow water to seep into rake or fascia boards. 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.

You will need to do this at the other end of the roof as well. Doing so keeps basements and crawlspaces dry and it also helps to.
