To convert between american roofing ratios and pitch degrees follow these steps. Next you will want to look for a hip roof angle calculator so that you can make sure all of your precision detailing for the roof itself is going to be. Here we consider two types of hipped roofs see picture. It can either be thought of as a gable roof with hipped ends cut short with the points turning downward.

What degree angle is a 12 12 pitch roof. Modern residential hip roof construction uses common pitch ratios in general. To derive formulas for the critical angles we need to define some terms which i do in figure 2. A jerkinhead roof uses elements of both gable and hip roofs.

For example you might need a hip roof framing calculator to work out the depth and the range of the frame that is to go up to make sure everything can be cut and prepared to the right size. A 12 12 pitch roof has a pitch angle of 45. Using these angle definitions i will derive formulas for the sheathing θ s and hip pitch angle θ h given the common pitch angle which i call the roof pitch θ r and plan angle θ p. For regular hips and valleys where the roof sections have the same slope and meet to form a 90 degree angle.

The most common hip roof pitch ratios fall between 4 12 and 6 12 although variations occur based on factors such as snow rain and wind conditions which is because steeper hip roof pitch ratios allow for less accumulations of snow and rain on the roof and lower ratios provide less wind resistance. Divide the first part of the ratio by 12 to work out the pitch. With the saw bevel angle set to 45 cutting hips and creepers at the plumb cut angle will produce correct side angles. If using a circular saw or compound miter saw set saw bevel angle to 45 to obtain creeper and hip side angles.

A hip roof or a hipped roof is a style of roofing that slopes downwards from all sides to the walls and hence has no vertical sides. Or it can be described as a hip roof with two short sides.

Find the inverse tangent of the pitch to find the angle in degrees.
