Framing Eaves Of A Roof

The ceiling joists pushed the rafters up and gave extra height to the building.

Framing eaves of a roof.

Due to the steeper angle of gable roof the maximum width of the eaves is narrower than other shed styles. When designing an open eave with roof trusses make sure that you raise the heel of the truss and use a thicker top chord. And the line length measurement from the roof peak to the building wall is the hypotenuse. What hip roofs demand in extra framing.

Doing so raises the eave which. An eave is the part of a roof that overhangs the building s exterior walls. In wood frame construction the primary structural members of a gabled roof frame are the ridge board and the rafters. The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle.

On both ends of the roof i let the subfascia run out beyond the anticipated width of the rakes. A building with a hip roof has more eaves than a building with a gable roof. The run or half the building span is the base of the triangle. The rise or height of the roof at its peak is the altitude of the triangle.

If the lower section of the roof rafters or rafter tail extends beyond the exterior wall the projection forms an overhang or eave. A rake on the gable end of the roof can be created with the construction of additional roof framing. For gabled roofs the roof rafters extending beyond the wall caps creating an angled roof overhang on the eaves.
