Of course you don t need to live in a modern house to deal with a flat roof.

Flat roof overhang framing.

An eave is the edge of the roof that overhangs the face of a wall and normally projects beyond the side of a building. However there is also an architectural purpose to them. Before the roof sheathing goes on the open framing provides easy access for attaching the return blocking and the nailers for the rake soffit. It has a 1 4 pitch.

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. Start with roof framing. Flat roofs aren t architecturally logical as rain and snow will shed much more quickly off a sloped roof. 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. 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. 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. This video will.

Let s have a look at two different popular roof styles. From the eaves to the peak it s 10 feet high that s the rise. 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.

They also help to frame windows on upper stories. Roof framing members can be any number of materials depending on the span. Due to the steeper angle of gable roof the maximum width of the eaves is narrower than other shed styles. Wide especially when the eave overhang is less than 12 in.

Due to the shed s design a significant amount of rain runs off the rear of the shed. On the other edge a gable ladder is constructed which is formed from two rafters with noggins between that support the end rafter. To 18 in depending on the style of the building. 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.

Flat roofs can be used to create box shapes cantilevered into daring overhangs or can be planted to create usable vegetated gardens. Figure 10 40 and reduce that to 1 4. When designing a gable end eave without a return the dimensions to look at are the width of the trim set between 6 in. In the direction of the roof span the roof member simply cantilevers past the wall plate.

Thick and the overhang from the side wall set between 12 in. That is their functional purpose. The noggins extend back for a series of three rafters. A rake on the gable end of the roof can be created with the construction of additional roof framing.
