Width Of A Roof

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.

Width of a roof.

Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10. The roof area ra is calculated easily. Then calculate the pitch of the roof by placing a level against it angling the level so the bubble is centered and measuring the distance between the end of the level and the roof. To measure a roof start by measuring the length and width of the building s exterior walls and multiplying them to get the area.

Roof pitch is the measurement of a roof s vertical rise divided by its horizontal run. Roof pitch calculator results explained. It is often compared to slope but is not exactly the same. In the united states a run of 12 inches 1 foot is used and pitch is measured as the rise of the roof over 12 inches.
