Flat roof overhang framing.

When designing a gable end eave without a return the dimensions to look at are the width of the trim set between 6 in. Flat roofs aren t architecturally logical as rain and snow will shed much more quickly off a sloped roof. Roof overhang with a new cornice will make this building look like it was added on in 1900 not 1960. That is their functional purpose.

Start with roof framing. In the direction of the roof span the roof member simply cantilevers past the wall plate. Eaves form the overhang to distribute water clear of the walls. So this is why we left the plywood long utilizing the full 8 sheets.

They also help to frame windows on upper stories. However there is also an architectural purpose to them. On the other edge a gable ladder is constructed which is formed from two rafters with noggins between that support the end rafter. 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. Avoid gable ends that are over 8 in. 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. Flat roofs can be used to create box shapes cantilevered into daring overhangs or can be planted to create usable vegetated gardens.

For slanted roof sheds overhangs add character and facilitate proper drainage. Wide especially when the eave overhang is less than 12 in. Flat roof framing is relatively straightforward. Before the roof sheathing goes on the open framing provides easy access for attaching the return blocking and the nailers for the rake soffit.

Depending on the span many different materials can frame a flat roof.
