How To Lay Out A Hip Roof

There are many variations on hip roofs and their construction but for the purpose.

How to lay out a hip roof.

I ll start at the beginning with the easy bits before tackling the more complicated stuff and that way hopefully i ll make it really clear and easy to understand exactly how to set out measure cut and install hip and valley roof rafters. Depending on the size of the roof most hip roofs will have 4 6 short jack rafters that are spaced out every 20 inches 51 cm between the hip rafters and the king common rafters. This is covered in cutting common rafters mar 17. Before we explain hip rafters you need to understand how to lay out and cut common roof rafters.

Hipped roof construction can seem quite complicated to grasp at first but i m going to break it down and explain each area in detail. The walls of a hip roof are laid out from the center of the first common rafter. The other rafter are laid out from this one either 16 o c. The pitch of the roof is a ratio.

Calculate the roof pitch. Measure the distance between the angled hip rafter and the top of the wall at 20 in 51 cm increments and cut jack rafters to fit. This is a way of measuring the degree of steepness of the roof. So use a tape measure to find the height of the roof above the top wall of the building.

The key structural member is the hip rafter which spans from the building corner to the peak or the ridge. Continue rolling out the felt until you reach the roof hip on the other end. The first common rafter is the one on the end of the ridge. Move the roll of felt which you ve now severed from the strip on the roof up and out of your way.

The number of inches that the roof rises vertically for every foot of roof.
