Rise Over Run Roof Pitch Calculator

Enter the rise and run for the pitch length and angle of the rafter.

Rise over run roof pitch calculator. 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 most commonly used roof pitches fall in a range between 4 12 and 9 12. For example a pitch 1 12 means that per every twelve yards. Roof pitch is often expressed as a ratio between rise and run in the form of x 12.

The run is the distance from the outside of the wall to the inside of the ridge. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch. The triangle diagram will be re drawn to scale with all dimensions marked. A roof pitch that is based on a fixed rise and run and does not end up with a whole number is known as a bastard pitch.

In roof pitch calculator pitch value can be obtained by dividing n by. 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. Drag sliders to animate the results and diagram. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.

It can be assessed in two ways either as the angle the rafter makes with the horizontal or the proportion between the rise and the run of the roof. The rise is the distance from the top of the roof to the bottom. The pitch is commonly defined as the ratio of rise over run in the form of x 12. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.

Roof pitch calculator results explained. The rise is the height of the roof and the run is the horizontal span as pictured above. Calculate roof pitches with this free and simple online tool. The roof pitch is important in determining the appropriate installation method and how much roofing material will be needed.

Roof pitch is simply the slope created by the rafter. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. Here is an online rise and run calculator which helps to calculate pitch slope and angle with the help of rise and run values. Roof pitch is used to describe the slope or angle of the roof.

For example if a roof has a pitch of 4 12 then for every 12 inches the building extends horizontally it rises 4 inches. Roof pitch is expressed as a ratio of the roof s vertical rise to its horizontal span or run.
