Intersecting Roofs Framing

Rafters are the sloping members that run from the roof ridge down to the tops of the walls.

Intersecting roofs framing.

The ridge board is the horizontal framing member that defines the roofline in a gable 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 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.

A jack rafteris a shortened com mon rafter that may be framed to a hip rafter a valley rafter or both. Type of roof because it is braced by four hip rafters. This type of roof is often seen in buildings with a more complex layout for example homes with an attached garage. A disadvantage of the hip roof is that it is more difficult to construct than a gable roof.

A cross gable roof is a design that consists of two or more gable roof ridges that intersect at an angle most commonly perpendicular to one another. After a taking some measurements and doing a bit of ciphering we established that the steepest pitch we could use on the porch roof was 4 in 12. We wanted to make the porch roof as steep as possible while keeping the peak of the roof below the wall to roof intersection at the top of the shed roof. Learn more about off angle roof framing.

That bid you submitted for the job with the adjoining unequally pitched roofs gets accepted and you ve got to figure out a way to frame it. Measure form the top of this line down the board to determine the line length or length of the rafter less the ridge. Explore framing complexities that result when roofs of two different pitches intersect. The valley is formed where the two different sections of the roof meet generally at a 90 angle.

Thus there arehip jack raftersand valley jack rafters. It extends from one. Position the square at the end of the rafter board with the tongue on your left and facing away from you. These hip rafters run at a 45 angle from each corner of the building to the ridge.
