Roof Overhang Framing

And the line length measurement from the roof peak to the building wall is the hypotenuse.

Roof overhang framing.

The other common wind related failure at gable ends is uplift of the roof decking at the overhang. The shed roof overhang is an important but neglected aspect of shed roof design. For slanted roof sheds overhangs add character and facilitate proper drainage. Inadequate nailing of the sheathing to supporting framing or inadequate connections of the framing at the rake edge that supports the roof.

The rise or height of the roof at its peak is the altitude of the triangle. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. This can be from two causes. The run or half the building span is the base of the triangle.

The biggest problems with gable end overhang strength occur if your roof overhang is greater than about 12 inches. The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle. Of the many ways that gable end overhangs are built the two most common ways are the use of ladder details and outriggers ladder details are usually adequate if the overhang is less than about 8 inches although they are frequently used for longer overhangs. Eaves form the overhang to distribute water clear of the walls.

A rake on the gable end of the roof can be created with the construction of additional roof framing. Due to the shed s design a significant amount of rain runs off the rear of the shed. Before the roof sheathing goes on the open framing provides easy access for attaching the return blocking and the nailers for the rake soffit. This video will.

An overhang helps direct water away from the foundation on the shed s low side. The last pieces to go in were nailing blocks above the ledger for the back of the return and at the bottom edge of the soffit for attaching the rake 20.
