How To Measure The Pitch Of A Roof Uk

You needn t measure the entire roof measuring out the set distance from the wall say a metre and then measuring the height of roof above that point will usually be sufficient to work out roof pitch.

How to measure the pitch of a roof uk.

Divide the height of your roof by the width not the full width if you ve measured the full width wall to wall divide this by 2 first h w to get your pitch as a percent. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. Pitch rise run 1 5 6 25. That measurement is the number of inches the roof rises in 12 inches.

For example if the roof rises 4 feet and the span is 16 feet twice the run then the pitch is 4 16 or 1 4. Next measure vertically from the 12 inch mark on the level straight up to the underside of the rafter as illustrated below. Move the tape measure along the the roof until it hits the level at exactly the 12 inch mark. Some homes will have roofs with multiple pitches.

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 represented as the ratio of rise to the span twice the run. Finally you can find the roof pitch in the form of x 12. Angle arctan pitch arctan 0 25 14.
