Pitch Range For Metal Roof

The most commonly used roof pitches fall in a range between 4 12 and 9 12.

Pitch range for metal roof.

In the usa the range of standard pitches is anywhere between 4 12 and 9 12. A a roof with a 6 rise for every 12 run has a 6 per foot or 6 in 12 pitch. So you would need to pick the right option as most regular standing seam metal roofs will require a roof pitch of 2 12 or even 3 12 at a minimum. To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope.

With regards to metal roofing the profile refers to the shape adopted by the metal sheets when they are bent to form the panels. Pitches of less than 2 12 are considered flat roofs even though they may be very slightly angled. Examples of extreme slopes range from 1 4 12 almost flat to 12 12 sloping down at a perfect 45 degree angle. This measurement is best done on a bare roof because curled up roofing shingles will impair your measurement.

The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. For every 12 horizontal feet the roof changes 8 feet in vertical height. Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels. In the uk the typical house has a pitch between 40 50 although 45 should be avoided.

There is no standard universal roof pitch. Minimum pitch for metal roof. For most home styles roof pitches fall in a range 4 12 a moderate slope up to 8 12 fairly steep. The picture below shows the pitch of a 7 12 roof slope meaning that for 12 of horizontal measurement roof run the vertical measurement roof rise is 7.

Roof pitch varies depending on culture climate style and available materials. Roof pitch or slope is a measure of vertical rise to horizontal run expressed in inches per foot. 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. There are some standing seam metal roofing options available from atas and other manufacturers that can be installed on a roof with pitch of 1 12.

Pitches above 9 12 are very highly angled and are designated steep slope roofs. Pitch is thus the ratio of the rise in inches to a 12 inch run and is often expressed using a semicolon for example 6 12. Panels joined with an applied lap sealant can go as low as 12. Pitches lower than 4 12 have a slight angle and they are defined as low slope roofs.

The minimum roof slope for metal roofs is dependent upon the roof profile.
