Framing Intersecting Roof Lines

The run or half the building span is the base of the triangle.

Framing intersecting roof lines. 353 framing with scissor trusses. 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. Explore framing complexities that result when roofs of two different pitches intersect. These hip rafters run at a 45 angle from each corner of the building to the ridge.

346 framing a truss roof system. A disadvantage of the hip roof is that it is more difficult to construct than a gable roof. A gable roof is fairly simple geometrically but when two gable roof lines intersect the geometry gets more complicated. The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle.

350 using a truss base to truss intersecting roofs. 348 framing a cantilevered truss roof system. Learn more about off angle roof framing. 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.

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. Front gable roofs have the roof ridge in line with the building s entrance. The valley is formed where.

The a frame is very easy to identify. 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. Type of roof because it is braced by four hip rafters. Intersecting the intersecting roof consists of a gable and valley or hip and valley.

And the line length measurement from the roof peak to the building wall is the hypotenuse. 356 framing a skylight well with trusses.
