Framing Between Two Peaks On A Roof

The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle.

Framing between two peaks on a roof.

Think of this as the total height of the roof itself. Gabled roofs are the kind young children typically draw. The rise refers to the height of each truss measured from the bottom of the roof segments to the top most point or peak of the roof. They have two sloping sides that come together at a ridge creating end walls with a triangular extension called a gable at the top.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. The run or half the building span is the base of the triangle. To scribe the angle we placed a length of stock on top of the rafter peaks and leveled it across using a scrap block to trace the angle. And the line length measurement from the roof peak to the building wall is the hypotenuse.

Part of a roof s frame a ridge board runs horizontally along the peak of a sloped roof. The pitch of the roof refers to the amount the roof slopes for every 12 inches it extends horizontally and it usually given as a fraction. The best time to replace a roof is between march 21 and september 21 because the sun s heat helps the shingles bond together better. In combination of roof styles a hip will connect to another part of the roof as part of the frame.

From gable to mansard read on to learn about the various roof shape types that add character and style to homes. Cold weather conversely reduces the effectiveness of the self adhesive strips under the shingles.

Generally wherever 2 sloped planes connect other than at a peak point a valley is formed. The ridge board is the horizontal framing member that defines the roofline in a gable roof. Where the porch roof extended over the shed roof we installed a 2x6 ridge that ran from the top of the dropped structural ridge to the apex of the sleepers. Valleys the inverse of a ridge or lines that appear to go inward on a roof.

The rise or height of the roof at its peak is the altitude of the triangle. A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. It extends from one gable end to the other at the peak of the roof.
