Hip Roof Slope Calculator

You can also calculate roof pitch even without using a roof slope calculator.

Hip roof slope calculator.

Here are the equations you may use to solve for the length of the slope and the rafter. Rafter rise run this formula is from the pythagorean theorem. Hip roof is a roof with a sharp edge or edges from the ridge to the eaves where the two sides meet. A hip roof s square footage is equal to that of a gable roof with the same dimensions.

Common roof pitches and equivalent grade degree and radian angles. A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. Determining the slope and skew angles related to hip and valley beams can be a challenge made even more difficult when the roof slopes on each side if the hip or valley are different. Select the following information by using the drop downs to enter values in feet and inches.

This slope and skew calculator makes it easy by performing all of the necessary trigonometry for each hanger condition in the roof. Most roof s have a pitch in the 4 12 to 9 12 range. The hip roof framing calculator returns the value of the main rafter the side rafter the length of the hip the height of the knee wall and the lengths of the jack rafters. After that you will have to try and find a good hip roof pitch calculator to make sure you can get the last of the calculations.

Learn more about finding the angle of a line using our slope calculator. Use the following formula which also describes a right triangle. Porch roof extensions for hip roof porch extensions from an existing building wall you can use half the calculator results. Here is the online hip roof area calculator which helps you calculate the hip roof parameters such as roof rise common and hip rafters length and roof area based on width height of roof base and the roof pitch identical for all sides.

Minus ridge thickness to allow for ridge becoming pole plate roof peak will be slightly higher ridge thick must be same. Hip roof area calculator. Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries. Slope and skew calculator.

The top ridge will be shorter for a hip roof but the 4 hips will add to the amount of ridge capping needed and because of the angles the amount of waste will be higher.
