Minimum Slope For Metal Roof With Snow

Keep in mind that neither metal shingles not corrugated metal panels are suitable options for low slope or nearly flat roofs.

Asphalt is the most versatile and works well in any roof pitch climate. The following table provides the minimum required allowable roof slope for each type of roofing material mentioned in the code. However if your area is prone to hail avoid installing a metal roof as denting will occur. The most common roofing material is asphalt shingles.

For the most part the minimum pitch for metal roof installations depends on what kind of material you are installing and the method in which the material is being fastened. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. A minimum slope of 1 inch per foot is recommended in snow country. Pitched roofs begin with with slopes greater than 3 in 12.

The minimum roof slope for metal roofs is dependent upon the roof profile. Typically large footprint single story. Roof slope is critical in determining that choice. The minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems.

With regards to metal roofing the profile refers to the shape adopted by the metal sheets when they are bent to form the panels. A minimum pitch of 3 in 12 or even 4 in 12 will normally be required.

The standing seam metal roof on this ice hockey rink leaked like a sieve a few weeks after the first snow arrived. The 1 4 inch per foot slope was not adequate. Minimum metal roof slope depends on the roof profile building design climate and site location. Suitable materials for pitched roofs.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Metal is rising in popularity as recycled options have improved in quality and can be cheaper than purchasing tiles. To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope.
