Shed Roof Slope Angle

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.

Shed roof slope angle.

This image shows a shed with a roof pitch of 30 degrees with a covering of cedar shingles. Therefore if your roof rises 4 inches over the course of 12 inches of horizontal run then your roof pitch is 4 12. A roof with a slope of 10 degrees 2 12 or less is generally considered a flat roof. Acceptable flat roof coverings include tin roof sheets and pre fabricated plastic sheets.

Beyond that you re free to choose whatever slope best fits your plans for your shed. 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. So far i have referred to the roof slope in degrees.

Roof pitch calculator the roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12. Roof pitch refers to the slope which the rafter creates. In roofing it is expressed in inches of vertical rise over inches of horizontal run. How is shed roof pitch measured.

Constructing a new shed roof at the desired pitch is as easy as knowing how to use a speed square. Shed roof a shed roof slopes in one direction only. A 4 12 pitch being 4 inches of vertical rise over one foot or 12 inches of horizontal run. Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run.

That is the way that my engineering mind works. Visit the shed roofing page. 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 always purchase a handy roof pitch and angle finder device to determine the roof slope.

This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement. 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.
