Shed Roof Slope Angle

Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run.

Shed roof slope angle. How is shed roof pitch measured. Acceptable flat roof coverings include tin roof sheets and pre fabricated plastic sheets. Roof pitch calculator the roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12. So far i have referred to the roof slope in degrees.

A 4 12 pitch being 4 inches of vertical rise over one foot or 12 inches of horizontal run. 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. If your roof pitch is greater than 3 your roof is considered pitched. Roof pitch refers to the slope which the rafter creates.

There are advantages and disadvantages to having a steep pitch versus a shallow or low pitch the most obvious of which is the roof s ability to shed or withstand heavy snow rain or wind. You can always purchase a handy roof pitch and angle finder device to determine the roof slope. A slope of 6 12 for example means that for every 12 inches 30 cm of length the angle of your roof rises 6 inches 15 cm. Often you express roof pitch as the ratio between the rise and the run in the form of x 12.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. As stated in the video speed squares have useful markings on them from 0 to 12. That is the way that my engineering mind works. Constructing a new shed roof at the desired pitch is as easy as knowing how to use a speed square.

Easy rafters is designed to calculate shed roofs that are framed to a ledger board nailed against a vertical wall not freestanding shed roofs supported by walls at both ends. Shed roof a shed roof slopes in one direction only. In roofing it is expressed in inches of vertical rise over inches of horizontal run. Visit the shed roofing page.

This image shows a shed with a roof pitch of 30 degrees with a covering of cedar shingles. 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.
