Roof Slope To Angle Conversion

First convert the pitch to a slope.

Roof slope to angle conversion.

Many different professions use slope in describing an angle. A steep roof usually sheds water quickly which is quite difficult to work on. 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. With a 12 in 12 slope the wall or roof rises 12 inches in a 12 inch run a 12 in 12 slope 45 one could be inclined to assume that a 6 in 12 slope would equal half of that 22 5.

You can assess this in two ways either as the roof pitch angles which the rafters make with the horizontal or the proportion between the run and the rise of the roof. To do this simply convert the rise and run as a fraction to a decimal form eg. With a mobile device a button will appear. Roof angles and rafter plumb cuts.

Both are referring to angles. To find the angle of a roof in degrees convert the pitch to a slope then convert to degrees by finding the arc tangent of the slope. Sometimes slope is referred to as pitch angle rise incline or grade. Roof pitch is a term describing how steep or flat your roof slope is.

Calculated out this gives an angle of 23 27 degrees. Tap the button to start measuring and lay your device on an angle roof to measure pitch and angle and animate the diagram. The following table shows the roof pitch rise in run equivalents for all roof slopes in degrees from 1 to 72. 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 pitch angle and slope factor charts. The roof pitch angle greatly factors into the replacement cost of the roof. The combination of two numbers are used to display or show the roof pitch. Visit this page on your phone to directly measure pitch and angles.

Roofs having a lower pitch have a greater chance of creating water leaks as well as ice damming and so they require an intensive waterproofing system. A 6 rise in a 12 inch run. Example slope as angle slope as angle for an elevation of 1 m over a distance of 2 m can be calculated as sangle tan 1 1 m 2 m 26 6. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

Rise run rise run slope. A 4 12 is a roof slope that rises by 4 inches for every 12 inches across. Roof pitch refers to the slope which the rafter creates.
