Roof Slope Pitch Angle

Angle the angle of a roof is the same as the roof s slope except instead of being represented as x 12 it is represented in degrees.

Roof slope pitch angle.

This is very useful information for many purposes especially for roof framing the slope sometimes called pitch is calibrated on speed squares. Roof pitch is a term describing how steep or flat your roof slope is. The combination of two numbers are used to display or show the roof pitch. First convert the pitch to a slope.

Roof pitch angle and slope factor charts. Often you express roof pitch as the ratio between the rise and the run in the form of x 12. To do this simply convert the rise and run as a fraction to a decimal form eg. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

Squaring building lines example 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. 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. Roof pitch refers to the slope which the rafter creates. 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.

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