Calculator roof pitch formula.

A speed square and level can be used to easily find the pitch of a roof. Roof pitch angle calculator briefly about the calculation. Set the level on the edge of the speed square as shown below then place the heel of the speed square on a rafter or gable edge of the roof. For example if your tape measure found a 6 inch vertical distance to the 12 inch mark on your level the slope is 6 12 or 6 in 12.

Angle the angle of a roof is the same as the roof s slope except instead of being. Roof pitch calculator results explained. There is no standard universal roof pitch roof pitch varies depending on culture climate style and available materials in the usa the range of standard pitches is anywhere between 4 12 and 9 12 in the uk the typical house has a pitch between 40 50 although 45 should be avoided. Here are the equations you may use to solve for the length of the slope and the rafter.

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. Use the following formula which also describes a right triangle. Contemporary houses often have flat roofs which shouldn. Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance.

The roof pitch angle calculator is used to calculate both the roof slope angle and the missing roof data the projection height length and slope angle of the roof. The pitch of this roof is 4 8 12. What is the standard pitch for a roof. You can also calculate roof pitch even without using a roof slope calculator.
