# 12 5 Degree Roof

### On blue prints architects engineers usually display the pitch of a roof in the format shown on the image where number 4 represents a rise and number 12 represents a length.

12 5 degree roof.

Most roof s have a pitch in the 4 12 to 9 12 range. The 30 degree 7 12 roof recommendation is backed up by testing according to the publication science daily. 5 12 roof pitch angle 22 62 degrees. But how are going to determine the angle s degree.

Also roof pitch angle is sometimes referred to as 12 12 6 12 8 12 and so forth. Divide the first part of the ratio by 12 to work out the pitch. A 12 12 pitch roof has a pitch angle of 45. To convert between american roofing ratios and pitch degrees follow these steps.

This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees. 5 12 roof pitch to angle 22 62 degrees also referred to as 5 12 roof slope 5 on 12 5 to 12 and 5 12 roof angle. 5 12 roof pitch angle 22 62 degrees. If this isn t practical then perform the same measurement on the underside of.

Lower slopes don t handle wind driven rain as well. 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. A 30 degree roof slope 7 12 pitch is the right pitch to aerodynamically handle high wind. We now realise that below 15 degrees the options are far more limited in terms of tile.

However our architect has designed the property with a 12 5 degree mono pitch roof. Steeper slopes increase the sail effect that makes them susceptible to wind. Common roof pitches and equivalent grade degree and radian angles. 5 12 roof pitch equivalents roof rises 5 in a length of 12.

Find the inverse tangent of the pitch to find the angle in degrees. We are in the process of building our own house. If a roof rises 5 in a length of 12 this is 5 12 roof pitch. The following are important details to better understand this conversion.

The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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. 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.
