Flat Roof Overhang Framing

For gabled roofs the roof rafters extending beyond the wall caps creating an angled roof overhang on the eaves.

Flat roof overhang framing.

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. Flat roofs can be used to create box shapes cantilevered into daring overhangs or can be planted to create usable vegetated gardens. 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.

That is their functional purpose. 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. However there is also an architectural purpose to them. The noggins extend back for a series of three rafters.

Avoid gable ends that are over 8 in. They also help to frame windows on upper stories. Flat roofs aren t architecturally logical as rain and snow will shed much more quickly off a sloped roof. From the eaves to the peak it s 10 feet high that s the rise.

For slanted roof sheds overhangs add character and facilitate proper drainage. When designing a gable end eave without a return the dimensions to look at are the width of the trim set between 6 in. An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. 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. In the direction of the roof span the roof member simply cantilevers past the wall plate. On the other edge a gable ladder is constructed which is formed from two rafters with noggins between that support the end rafter. Eaves form the overhang to distribute water clear of the walls.

Thick and the overhang from the side wall set between 12 in. Wide especially when the eave overhang is less than 12 in. 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. It has a 1 4 pitch.

Before the roof sheathing goes on the open framing provides easy access for attaching the return blocking and the nailers for the rake soffit. Start with roof framing. Due to the steeper angle of gable roof the maximum width of the eaves is narrower than other shed styles. That makes the roof s span 40 feet.

Let s have a look at two different popular roof styles. Figure 10 40 and reduce that to 1 4. Roof framing members can be any number of materials depending on the span. Say your house is 38 feet wide and the gable roof has a 1 foot overhang on each side.
