Flat Roof Overhang Framing

That makes the roof s span 40 feet.

Flat roof overhang framing. The noggins extend back for a series of three rafters. Yet for historic modern style buildings like this old house s cambridge tv project flat roofs are at the core of the architecture meant to reflect the broad horizontal lines of the natural landscape. Say your house is 38 feet wide and the gable roof has a 1 foot overhang on each side. Eaves form the overhang to distribute water clear of the walls.

Flat roofs can be used to create box shapes cantilevered into daring overhangs or can be planted to create usable vegetated gardens. Flat roofs aren t architecturally logical as rain and snow will shed much more quickly off a sloped roof. A rake on the gable end of the roof can be created with the construction of additional roof framing. The framing system for shed roofs is straightforward and similar to that of flat roofs.

They also help to frame windows on upper stories. 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. Thick and the overhang from the side wall set between 12 in. Wide especially when the eave overhang is less than 12 in.

For slanted roof sheds overhangs add character and facilitate proper drainage. For gabled roofs the roof rafters extending beyond the wall caps creating an angled roof overhang on the eaves. Due to the steeper angle of gable roof the maximum width of the eaves is narrower than other shed styles. In the direction of the roof span the roof member simply cantilevers past the wall plate.

Before the roof sheathing goes on the open framing provides easy access for attaching the return blocking and the nailers for the rake soffit. From the eaves to the peak it s 10 feet high that s the rise. To 18 in depending on the style of the building. Of course you don t need to live in a modern house to deal with a flat roof.

This video will. Flat roofs come in many shapes and sizes which include parapet roofs roof decks and green roofs to name just a few of the options available. Because the roof slope is steeper than for flat roofs it makes much more sense to slope the roof framing in this case to follow the roof pitch. It has a 1 4 pitch.

However there is also an architectural purpose to them. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. Let s have a look at two different popular roof styles. When designing a gable end eave without a return the dimensions to look at are the width of the trim set between 6 in.

Due to the shed s design a significant amount of rain runs off the rear of the shed. That is their functional purpose. Start with roof framing. Avoid gable ends that are over 8 in.
