Calculator Roof Pitch Formula

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

Calculator roof pitch formula.

Measure with a speed square. Rafter rise run this formula is from the pythagorean theorem. The calculator above can handle much of this math. Calculate the roof slope.

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. 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. 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.

Angle the angle of a roof is the same as the roof s slope except instead of being. Here are the equations you may use to solve for the length of the slope and the rafter. Contemporary houses often have flat roofs which shouldn. A speed square and level can be used to easily find the pitch of a roof.

Visually where and what values can be seen in the drawing of the calculator which is under the form of calculation. 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. The pitch of this roof is 4 8 12. Write the roof slope as the ratio of rise over run or vertical distance over horizontal distance.

Use the following formula which also describes a right triangle.
