Min Shed Roof Pitch

I always recommend at least a minimum pitch of 1 in 40.

Min shed roof pitch.

As stated in the video speed squares have useful markings on them from 0 to 12. Standing seam is the metal roof profile that has been gaining more popularity nowadays due to its clean and modern looks. There are some opinions that standing seam metal roof minimum slope is 12 but it increases the possibility of leaking on the few first days of snow arrival. Which is the easiest shed roof pitch to build.

If you are only trying to keep a wood pile dry or storing a few outdoor tools and light machinery out of the weather then you might consider a simple single pitch roof since most everything inside will be stored at ground level and pulled out from the outside of the shed. The minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems. Much depends on what your intended use for the shed actually is. There is no fabrication of roof trusses required.

My reasoning for this is that all that is required is a simple beam. Therefore if your roof rises 4 inches over the course of 12 inches of horizontal run then your roof pitch is 4 12. The pitch is measured in inches of vertical rise per foot of horizontal run and the 5v crimp profile shown above requires a minimum slope of three in twelve or 3 12 3 inches vertically per 12 inches horizontally. Just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of the roof.

The roof joists can be fixed spanning directly between wall plates. The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. Remember that pitch is calculated as the height or rise of a roof pitch over 12 inches of horizontal run. In most occasions a pitch of three in twelve is preferred but this should also take into consideration the manufacturer s recommendations as well the unique condition of the corrugated metal roof.

Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels. However you can only use this pitch with built up roofing or specialized synthetic roofing.
