Constructing a new shed roof at the desired pitch is as easy as knowing how to use a speed square.
Roof pitch for lean to shed.
Looking at a construction plan it is represented by a triangle shaped drawing which is written in inches.
In other words if there is a 1 1 2 ridge board nailed into the wall and the width of the lean to is 96 then the run will be 94 1 2 96 1 1 2 94 1 2.
Solutions for lean to sheds.
Having a steeper pitched roof allows for more space in a shed loft.
Pitched roofs can also be used to incorporate roof lights angled in a specific direction or dormer windows.
A roof pitch for a shed is the angle or slope on which the roof falls from its ridge to its gutter.
The run for a lean to shed rafter ending into a wall should account for the ridge board nailed into the wall where the tops of the rafters rest into.
Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run.
Regular asphalt shingles that are rated for 4 in 12 roof slopes can be installed on lower slope roofs by simply installing a waterproof membrane under them.
The loft space would be much larger with a roof pitch of 45 degrees.
Some builders even choose to match it directly especially if the shed s roof is attached to the house on the high side and just one simple span pitch.
It is determined by finding the rise amount in each foot run.
Therefore if your roof rises 4 inches over the course of 12 inches of horizontal run then your roof pitch is 4 12.
As stated in the video speed squares have useful markings on them from 0 to 12.
