Minimum Slope For Metal Roof With Snow

Roof slope is critical in determining that choice.

Minimum slope for metal roof with snow.

A minimum pitch of 3 in 12 or even 4 in 12 will normally be required. Minimum pitch for metal roof. In country with heavy snow and tough winter days the metal roof minimum slope is recommended to be 1 12. The minimum roof slope for metal roofs is dependent upon the roof profile.

To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope. The 1 4 inch per foot slope was not adequate. With regards to metal roofing the profile refers to the shape adopted by the metal sheets when they are bent to form the panels. The following table provides the minimum required allowable roof slope for each type of roofing material mentioned in the code.

The standing seam metal roof on this ice hockey rink leaked like a sieve a few weeks after the first snow arrived. Metal is rising in popularity as recycled options have improved in quality and can be cheaper than purchasing tiles. Let s take a look at some of the main things to consider when choosing a metal roof panel with regard to roof slope including building codes minimum slope requirements and typical applications. 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.

The most common roofing material is asphalt shingles. Minimum metal roof slope depends on the roof profile building design climate and site location. Low slope metal roofs require less material which reduces the overall load on the building s structure. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12.

Typically large footprint single story. Keep in mind that neither metal shingles not corrugated metal panels are suitable options for low slope or nearly flat roofs. Suitable materials for pitched roofs. A minimum slope of 1 inch per foot is recommended in snow country.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Pitched roofs begin with with slopes greater than 3 in 12. The minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems.
