Minimum Slope For Shed Roof

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.

Minimum slope for shed roof.

Remember metal roofing is more expensive than shingles. Furthermore a roof in a forest should have a slope of at least 2 12 to shed. To shed the snow. Express the slope of a metal roof by a ratio which indicates the pitch of the roof.

An important factor to throw into a discussion about roof pitches is local planning rules and regulations. 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 pitch for a roof is 1 4 12 which translates to 1 4 inch rise to 12 inches of run. The roof joists can be fixed spanning directly between wall plates.

I always recommend at least a minimum pitch of 1 in 40. The shed roof pitch has two slopes and the window above eaves level allows additional light into the shed. 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. Asphalt shingles typically have a minimum slope rating of 4 in 12.

Much depends on what your intended use for the shed actually is. The profile is the shape taken by the sheets when you bend them to form panels.
