Take the measurement of the vertical. 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. In degrees 10 2 in 12 or 1 in 6 is considered a minimum. Angle arctan pitch arctan 0 25 14.

So let s say a roof rises 6 inches for every 12 inches in depth towards the peak. Calculate the roof pitch as the proportion of rise and run. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. Thus pitch is typically greater in areas of high rain or snowfall.

For a roof with the ridge above one wall the span is the same as the run. Roof pitch calculator results explained 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.

Finally you can find the roof pitch in the form of x 12. Position your level against the roof until the bubble of the vial sits between two lines. If you want to know how to find the pitch of a roof then start with a calculator. That is to say the roof pitch expressed as a ratio tells you how many inches the roof rises for every 12 inches of depth.

First measure 12 inches from one end of the level and make a mark. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Definitions vary on when a roof is considered pitched. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally.

Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. Take a measurement of 12 inches using a level. Recalculate this value into an angle. Rafter rise run 1 5 6 2 25 36 38 25rafter 38 25 6 18 m.

Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow. This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. The primary reason roof pitch exists in the first place is to redirect water.

Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot.
