Framing Intersecting Roof Lines

In a standard gable roof the ridge.

Framing intersecting roof lines. Thus there arehip jack raftersand valley jack rafters. This type of roof is more complicated than the figure 2 1 most common types of pitched roofs. The valley is formed where the two different sections of the roof meet generally at a 90 angle. Explore framing complexities that result when roofs of two different pitches intersect.

It extends from one gable end to the other at the peak of the roof. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. Intersecting the intersecting roof consists of a gable and valley or hip and valley. A jack rafteris a shortened com mon rafter that may be framed to a hip rafter a valley rafter or both.

A hip rafter is called for only when framing a hip roof but a valley rafter is needed on both hip and gable roofs whenever roof planes intersect. Learn more about off angle roof framing. To transition the eaves the horizontal fascia extends to the last rafter tail and a vertical return finishes the transition. Measure form the top of this line down the board to determine the line length or length of the rafter less the ridge.

At the low end of the valley the subfascias of the two roofs are mitered with a block filling in the roof framing. The ridge board is the horizontal framing member that defines the roofline in a gable roof. Sheathing blocking is added along the valley and the sheathing pieced in for both roof planes. Is that it is more difficult to construct than a gable roof.

Add the length of the overhang beyond this mark and.
