Slope of roof in degrees.

Sometimes slope is referred to as pitch angle rise incline or grade. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. How to convert roof pitch in degrees converting this mathematical formula is not that easy especially if you don t have a lot of skill when it comes to math. Example slope as grade.

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. Degrees tan 1 43 calculated out this gives an angle of 23 27 degrees. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. To put it in perspective the angle of this slope would be around 30 degrees.

Low slope roofing needs special techniques and materials in order to avoid leaks and roof damage and it ranges from 1 12 4 12. The slope of a roof or pitch is determined by how many inches the roof rises over 1 foot or 12 inches. In some very steep roofs you may see the gradient inverted so that the run varies but the rise is held as 12. You can find the roof pitch in the form of x 12 like 4 12 or 9 12.

Roof pitch refers to the measurement of the slope of a roof and you express this as a ratio. Although there s isn t any standard pitch of a roof used on all kinds of sloped roofs you can determine the range of pitches by using a roof angle calculator and by considering factors like the local climate and roofing materials. Low slope roofs have gradients of 3 12 or less. This forms an angle of 18 5 between the horizontal section and the roof and creates a gentle incline that is seen as a midpoint between a low pitch and medium pitch roof.

Roof slopes are identified using the gradient method described above where the rise varies but the run is usually 12. 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. Many different professions use slope in describing an angle. S grade 1 m 2 m 50 slope and roof pitch.

An example for a steep sloped roof is 8 12. Slope as grade for an elevation of 1 m over a distance of 2 m can be calculated as. Roof pitch on the form x 12 can be expressed in grades as. This means that the rise of the slope goes up or down 8 inches for every 12 inches.

Roof pitch is the slope created by the rafter.
