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.
Shed roof slope angle.
Roof pitch calculator the roof pitch measures the steepness of your shed roof and typically takes values from 1 to 12.
This image shows a shed with a roof pitch of 30 degrees with a covering of cedar shingles.
Visit the shed roofing page.
Constructing a new shed roof at the desired pitch is as easy as knowing how to use a speed square.
A 4 12 pitch being 4 inches of vertical rise over one foot or 12 inches of horizontal run.
In roofing it is expressed in inches of vertical rise over inches of horizontal run.
If your roof pitch is greater than 3 your roof is considered pitched.
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.
How is shed roof pitch measured.
Beyond that you re free to choose whatever slope best fits your plans for your shed.
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.
Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run.
Shed roof a shed roof slopes in one direction only.
So far i have referred to the roof slope in degrees.
Acceptable flat roof coverings include tin roof sheets and pre fabricated plastic sheets.
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.
Often you express roof pitch as the ratio between the rise and the run in the form of x 12.
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.
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.
This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.
Roof pitch refers to the slope which the rafter creates.
