Rise vers run on roof pitch. 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. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. For example a pitch 1 12 means that per every twelve yards. Enter run the flat level length then click pitch angle or rise to select then enter other known dimension angle or pitch.

Finding the pitch of a roof can be done by. We give the required roof slopes for different types of roofing materials and we illustrate several methods by which the slope or pitch of a roof is easily measured. This article defines different types or degrees of roof slope and explains how roof slope ptich angle or grade slope are measured expressed. 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.

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. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. The run is the distance from the outside of the wall to the inside of the ridge. 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 triangle diagram will be re drawn to scale with all dimensions marked. Roof pitch is simply the slope created by the rafter. Roof pitch is often expressed as a ratio between rise and run in the form of x 12. Enter the rise and run for the pitch length and angle of the rafter.

A roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. In roof pitch calculator pitch value can be obtained by dividing n by. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Roof pitch calculator results explained.

The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. As aforementioned there is no standard pitch of a roof. Calculate roof pitches with this free and simple online tool.

The rise is the distance from the top of the roof to the bottom. Sometimes pitch is also expressed in fraction form using a fraction with a slash such as 6 12.
