Rise And Run Roof Calculator

The triangle diagram will be re drawn to scale with all dimensions marked.

Rise and run roof calculator.

As aforementioned there is no standard pitch of a roof. The value displayed as the rise will be your x. Enter run and known pitch angle or rise to calculate other dimensions enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. Calculate roof pitches with this free and simple online tool.

Drag sliders to animate the results and diagram. One method to find the pitch is to climb on the roof and measure the rise for a 12 run. If you want to find the roof pitch in the form of x 12 simply calculate the pitch and substitute 12 for the run length. The roof pitch calculator finds the length of the rafter and the roof slope in degrees and in percents and our roof pitch calculator also finds pitch in inches per foot slope degrees and rise over run.

This is rarely is a whole number it is not a rare event and it is not a nightmare. Pitch tan angle where angle is the roof pitch expressed in degrees. In roof pitch calculator pitch value can be obtained by dividing n by 12 and divide s by the answer. Enter the rise and run for the pitch length and angle of the rafter.

Use the diagrams on this page as a reference when inputting rise and run and while interpreting the calculated results. Express roof pitch as the ratio of the amount of the vertical rise of a roof or rise over the corresponding horizontal distance or run you write the pitch assuming a run of 12 inches thus the ratio would describe how much a roof rises for each foot of the run. The roof pitch calculator calculates slope pitch angle and rafter lengths based on input of rise m and run r. Rise run pitch where pitch is expressed in percent.

You ll need a level that is 12 or longer and a tape measure. Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values.
