How To Write Roof Pitch

The slope is the same as the pitch.

How to write roof pitch.

First measure 12 inches from one end of the level and make a mark. 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. Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally.

Calculate the roof pitch as the proportion of rise and run. Leah s recommended tools for beginner diy ers. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch.

The roof pitch would be described as a 6 12 pitch. For a roof with the ridge above one wall the span is the same as the run. Leah answers a viewer s question about how to calculate the pitch of a roof on a structure. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level.

X pitch 12 0 25 12 3. Pitch rise run 1 5 6 25. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil. 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.

As aforementioned there is no standard pitch of a roof. Divide the slope by two to get the pitch. So let s say a roof rises 6 inches for every 12 inches in depth towards the peak. Pitch is the incline of the roof expressed as a fraction derived by dividing the rise by the span where the roof span is the distance between the outside of one wall s top plate to another.

It can also be written down as 25 or 14. The primary reason roof pitch exists in the first place is to redirect water. Angle arctan pitch arctan 0 25 14 finally you can find the roof pitch in the form of x 12. The pitch of a roof is its vertical rise over its horizontal span.

Recalculate this value into an angle. The pitch of your roof is 3 12.
