This means that for every 12 inches of horizontal distance across the shed the roof will rise 4 inches.
Minimum slope for shed roof.
You need to consider the slope requirements of each panel to determine this minimum slope.
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.
Express the slope of a metal roof by a ratio which indicates the pitch of the roof.
To shed the snow.
The minimum pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run.
The shed roof pitch has two slopes and the window above eaves level allows additional light into the shed.
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.
Much depends on what your intended use for the shed actually is.
A quarter inch slope is the lowest you would go with a metal roof experts recommend at least a half inch minimum to ensure a weatherproof interior for your shed.
I always recommend at least a minimum pitch of 1 in 40.
Furthermore a roof in a forest should have a slope of at least 2 12 to shed.
Asphalt shingles typically have a minimum slope rating of 4 in 12.
The minimum slope of a roof depends on the roof s profile.
An important factor to throw into a discussion about roof pitches is local planning rules and regulations.
