How To Write Roof Pitch

Divide the slope by two to get the pitch.

How to write roof pitch.

As aforementioned there is no standard pitch of a roof. To see how pitch impacts the look of a garage and changes cost click the design center button on our pole barn kits page. Recalculate this value into an angle. For a roof with the ridge above one wall the span is the same as the run.

Roof pitch refers to the amount of rise a roof has compared to the horizontal measurement of the roof called the run. Then in the attic place the end of the level against the bottom of a roof rafter and hold it perfectly level. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. To measure the roof pitch you ll need an 18 or 24 inch level a tape measure and a pencil.

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. 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. The slope is the same as the pitch. Leah answers a viewer s question about how to calculate the pitch of a roof on a structure.

Pitch rise run 1 5 6 25. The pitch of your roof is 3 12. The roof pitch would be described as a 6 12 pitch. X pitch 12 0 25 12 3.

Leah s recommended tools for beginner diy ers. First measure 12 inches from one end of the level and make a mark. However most often a ratio of pitch also fraction is slang used for the more useful slope of rise over run of just one side half the span of a dual pitched roof. So let s say a roof rises 6 inches for every 12 inches in depth towards the peak.

For a simple gable roof the span wall to wall will be twice the size of the run wall to ridge horizontally. The pitch of a roof is its vertical rise over its horizontal span. It can also be written down as 25 or 14. 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.

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