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

Roof slope 4 12 in degrees.

See below after the table for directions on how to convert any roof slope from one form to another even roof slopes not shown in the table. Select the best roof trusses and budget amount. Low slope roofing needs special techniques and materials in order to avoid leaks and roof damage and it ranges from 1 12 4 12. This means if a roof rises 4 in the length of 12 your roof pitch would be 4 12 or 18 43 degrees.

4 12 roof pitch to angle 18 43 degrees equivalents. Enter any pitch or fraction of pitch to find angle. Also see our page quick reference. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across.

The following table shows how the same common roof slopes can be expressed using rise in run ratios degrees and percentages. 45 this is our pitch calculator which will convert pitch to angle or angle to pitch for half degree roof slope calculations.

A 4 in 12 pitch becomes 4 12 then divide. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. Degrees atan slope. 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.

They have a pitch ranging from 4 12 to 9 12. Conventional roofs are the easiest to construct and you can walk on them safely. These roofs have a pitch less than 4 12. What roof angle in degrees.
