Framing Eaves Of A Roof

The rise or height of the roof at its peak is the altitude of the triangle.

Framing eaves of a roof.

A building with a hip roof has more eaves than a building with a gable roof. On both ends of the roof i let the subfascia run out beyond the anticipated width of the rakes. And the line length measurement from the roof peak to the building wall is the hypotenuse. A rake on the gable end of the roof can be created with the construction of additional roof framing.

When designing an open eave with roof trusses make sure that you raise the heel of the truss and use a thicker top chord. The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle. The run or half the building span is the base of the triangle. What hip roofs demand in extra framing.

The ceiling joists pushed the rafters up and gave extra height to the building. Due to the steeper angle of gable roof the maximum width of the eaves is narrower than other shed styles. An eave is the part of a roof that overhangs the building s exterior walls. Finish the eaves framing after ripping the top of the subfascia with a circular saw set to 26 5 degrees i flushed the top ripped edge with the top of the plumb cut on the rafters and screwed the subfascia to the rafter tails.

If the lower section of the roof rafters or rafter tail extends beyond the exterior wall the projection forms an overhang or eave. Before roof trusses the exposed rafter tails were an extension of the roof framing. For gabled roofs the roof rafters extending beyond the wall caps creating an angled roof overhang on the eaves.
