Framing Intersecting Roof Lines

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.

Framing intersecting roof lines.

The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle. A gable roof is fairly simple geometrically but when two gable roof lines intersect the geometry gets more complicated. 349 framing with energy heel trusses. These hip rafters run at a 45 angle from each corner of the building to the ridge.

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. 348 framing a cantilevered truss roof system. A disadvantage of the hip roof is that it is more difficult to construct than a gable roof. The a frame is very easy to identify.

346 framing a truss roof system. Type of roof because it is braced by four hip rafters. 353 framing with scissor trusses. Intersecting the intersecting roof consists of a gable and valley or hip and valley.

The valley is formed where. Front gable roofs have the roof ridge in line with the building s entrance. Explore framing complexities that result when roofs of two different pitches intersect. 350 using a truss base to truss intersecting roofs.

Learn more about off angle roof framing. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. The rise or height of the roof at its peak is the altitude of the triangle. The framing required at the intersection of two roof lines is easy to.

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. However laying out the framing of the intersecting roof lines properly is simply a matter of making sure that the roof s weight is adequately supported at the points of intersection and.
