15 12 Pitch Roof

Two most common methods 4 12 or 4 12 are used for marking the pitch of a roof.

15 12 pitch roof. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7. Roof pitch defined and explained. The ratio can be indicated by a division slash separating the numbers such as 2 12 or 7 12.

Roof pitch designations are comprised of two numbers indicating a ratio. Roof pitch is a term describing how steep or flat your roof slope is. Other than the 45 roof slope which is 12 in 12 none of the standard roof pitches 5 in 12 6 in 12 etc are equal to a whole degree. Arctan 3 12 14 0 the primary purpose of pitching a roof is to redirect water and snow.

A pitch over 9 12 is considered a steep slope roof between 2 12 and 4 12 is considered a low slope roof and less than 2 12 is considered a flat roof. The combination of two numbers are used to display or show the roof pitch. Pitch is the term used to describe the angle slope or slant of your roof.

The table below shows common roof pitches and the equivalent grade degrees and radians for each. The steep roof of the tropical papua new guinea longhouse for example sweeps. The exact roof slope in degrees is given by the arctangent. 8 12 roof pitch 33 angle 33 69 degrees details 9 12 roof pitch 37 angle 36 37 degrees details.

7 12 roof pitch 30 angle 30 26 degrees details. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. For a more detailed explanation of the roof pitch multiplier see how to find the area of a sloped roof if you know the roof pitch in degrees find the secant of the slope using a scientific calculator for example if the roof pitch is 45 then sec 45 1 414213. Or the colon can replace the slash as in 2 12 or 7 12.

Thus pitch is typically greater in areas of high rain or snowfall.
