Normal Roof Overhang

The roof overhang will be 36 inches at the eaves measured horizontally and 36 inches at the gable ends.

Normal roof overhang.

As a rule there are two popular methods in framing it pant or flat roof overhang and gable roof overhang. A typical metal roof overhang may be 2 to 4 inches or even less. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. Metal is usually installed on rafters or strip sheathing rather than the solid decking used under other materials.

Additionally forming this needs to pay attention to the edge of your roof. However there is also an architectural purpose to them. Two feet is the general maximum length for a typical roof overhang. Roof overhangs can extend farther than 2 feet but beyond this length they begin to lose structural integrity and require external supports.

Some slight overhang is recommended in conjunction with a drip edge flashing to prevent water from getting under the roofing and onto underlying wood. This will protect a roof from most types of damage. Eaves form the overhang to distribute water clear of the walls. There is a certain logic in extending the gable overhang further the higher you get as you mention but that complicates the roof and i don t like the look of it.
