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.
Googd roof pitch for shed.
In the simplest possible terms shed roof pitch is defined as the amount of rise per foot of run.
This means that for every 12 inches of horizontal distance across the shed the roof will rise 4 inches.
Looking at a construction plan it is represented by a triangle shaped drawing which is written in inches.
This image shows a relatively shallow roof pitch of 15 degrees.
It is determined by finding the rise amount in each foot run.
As stated in the video speed squares have useful markings on them from 0 to 12.
The loft space would be much larger with a roof pitch of 45 degrees.
Constructing a new shed roof at the desired pitch is as easy as knowing how to use a speed square.
Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run.
Having a steeper pitched roof allows for more space in a shed loft.
Basically the steeper the pitch the better it can shed snow and rain.
Therefore if your roof rises 4 inches over the course of 12 inches of horizontal run then your roof pitch is 4 12.
Asphalt shingles typically have a minimum slope rating of 4 in 12.
This slope works well for sheds that are fairly narrow like 4 to 6 feet but for sheds that are 8 or wider the shed roof becomes unsightly high.
