Framing Overhang For Roof

This can be from two causes.

Framing overhang for roof.

Floor cantilevers supporting an exterior balcony are permitted to be constructed in accordance with table r502 3 3 2. Floor cantilever spans shall not exceed the nominal depth of the wood floor joist. Floor cantilevers constructed in accordance with table r502 3 3 1 shall be permitted where supporting a light frame bearing wall and roof only. Eaves form the overhang to distribute water clear of the walls.

For slanted roof sheds overhangs add character and facilitate proper drainage. They also help to frame windows on upper stories. Before the roof sheathing goes on the open framing provides easy access for attaching the return blocking and the nailers for the rake soffit. You need to measure the area where you will be adding the overhang and buy to fit your specific project.

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. Due to the shed s design a significant amount of rain runs off the rear of the shed. If you are unsure of how to measure for your overhang framing ask for help at your local hardware store. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building.

8d ring shank nails should be used instead. Again have the helper hold the rafter extension in place and gauge the distance of the overhang while you hold the extension against the rafter and the roof sheathing and nail it to the existing rafter with a framing nailer. The other common wind related failure at gable ends is uplift of the roof decking at the overhang. The typical thickness range for sheathing is 3 8 to 3 4 inch.

Or less you might try a technique that bob syvanen wrote about in dummy rafter tails way back in 1985. If narrow overhangs are all you need say 8 in. Roof sheathing comes in grid marked 4 by 8 foot sheets and should be installed perpendicular to the frame. Over hangs are recommended to not exceed three feet out.

Make sure to purchase weather resistant materials. Inadequate nailing of the sheathing to supporting framing or inadequate connections of the framing at the rake edge that supports the roof. A rake on the gable end of the roof can be created with the construction of additional roof framing. Uplift of roof decking at the overhang.
