Roof Eave Framing

Open eaves with trusses.

Roof eave framing.

A building with a hip roof has more eaves than a building with a gable roof. The rise or height of the roof at its peak is the altitude of the triangle. And the line length measurement from the roof peak to the building wall is the hypotenuse. The run or half the building span is the base of the triangle.

Doing so raises the eave which. To keep the porch roof framing as simple as possible we installed a structural ridge supported by posts at each end with the common rafters landing on top of the ridge. What hip roofs demand in extra framing. The ceiling joists pushed the rafters up and gave extra height to the building.

Before roof trusses the exposed rafter tails were an extension of the roof framing. After installing the rafters we still had to extend the porch roof back over the shed roof creating a valley on either side. Blind valleys simplify 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. 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. On both ends of the roof i let the subfascia run out beyond the anticipated width of the rakes.
