Intersecting Roof Angles

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.

Intersecting roof angles.

When two perpendicular roof lines meet their ridges intersect at a right angle and their rafters slope at a right angle to each other. This tutorial shows how to calculate roof rafter dimensions and angles for intersecting roof planes as in shed or dormer roof applications. 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. The porch joined the house at right angles to a shed roof section.

A sketchup model helps clarify how various rafters and framing components are assembled in an off angle hip and valley configuration. Learn more about off angle roof framing. Roof pitch slope roof angle degree 1 12 pitch. After a taking some.

So where two roof sections intersect to form a 90 angle a regular hip or valley and each roof section has for example a 6 in 12 slope the hip or valley rafter at that intersection will have. We designed the porch with wide overhangs for shade from the hot north carolina summer sun. On a related note the pitch properly the slope of a hip or valley rafter will not be the same as the pitch of the adjacent roof sections. Explore framing complexities that result when roofs of two different pitches intersect.

Slope the slope of a roof is represented as x 12 where x is the number of inches in rise for every 12 inches of run this is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. With this method. Roof pitch calculator results explained. Angle the angle of a roof is the same as the roof s slope except instead of being.
