Hip roof slope calculator.

Hip roof area calculator. Hip roof is a roof with a sharp edge or edges from the ridge to the eaves where the two sides meet. This slope and skew calculator makes it easy by performing all of the necessary trigonometry for each hanger condition in the roof. 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.

Learn more about finding the angle of a line using our slope calculator. Enter the extension wall length into wall length and double the extension wall width then minus ridge thickness into the wall width entries. 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. Slope and skew calculator.

A hip roof s square footage is equal to that of a gable roof with the same dimensions. Use the following formula which also describes a right triangle. 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. You can also calculate roof pitch even without using a roof slope calculator.

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. Select the following information by using the drop downs to enter values in feet and inches. Common roof pitches and equivalent grade degree and radian angles. The difference is in the amount of ridge capping you need and the amount you will waste.

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. 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. Most roof s have a pitch in the 4 12 to 9 12 range.

Rafter rise run this formula is from the pythagorean theorem.
