Question: What is the minimum pitch for a standing seam metal roof?

The minimum slope for standing seam of roof systems shall be one-quarter unit vertical in 12 units horizontal (2-percent slope).

What is the lowest slope for a standing seam metal roof?

For standing-seam metal roof panel systems, a 1/4:12 minimum roof slope is prescribed.

Can you put metal roofing on a 1/12 pitch?

The minimum pitch for a lapped, non-sealed metal roof is 3:12. That ratio equals just over 14 degrees. Lapped metal roofs with sealant between the laps can go as low as ½:12, which equals around 2.5 degrees. Standing seam metal roofs have an angle of just over 1 degree.

Can you put a metal roof on a low slope?

Metal roofing systems, such as a standing seam roof or a corrugated metal roof, are ideal for low-slope applications that aren’t “flat” roofs. These metal panels come in large sheets that cover the length of your roof from your ridge to your gutter.

What slope is required by that metal roofing?

The minimum slope for the application of architectural standing seam metal roofing is 2:12 (1:6). For slopes between 2:12 and 3:12, see standing seam requirements in item 2.8. 5.

What is the minimum pitch for a corrugated metal roof?

Corrugated metal roofing requires a minimum roof slope of 3” in 12”. It is not intended for a low slope roof.

What is the minimum pitch for corrugated iron roof?

Corrugated roofing is a great material on traditional pitched roofs – but it has severe limitations when the pitch gets below 5 degrees. That is why all roofing manufacturers recommend the 5 degree pitch as the minimum slope and they will not provide any guarantees if it is installed flatter than this.

What is the minimum roof pitch?

Smallest Roof Pitch

The smallest pitch of a roof is 1/4:12, which translates to 1/4 inch rise to 12 inches of run. Such a small pitch can only work with built-up roofing or specialized synthetic roofing. Covered porches that are near trees or in areas with heavy rains should not be covered with a low-slope roof.

What is the minimum pitch for a zinc roof?

SIG Zinc and Copper recommend that the minimum pitch for a standing seam zinc roof is five degrees, with an absolute minimum of 3 degrees. We recommend 5 degrees, however, due to site conditions and execution. A 3-degree roof pitch means just over 50mm in every metre, so over 3 metres you only have 150mm to play with.

Can you Shingle a 1/12 pitch roof?

Asphalt shingles are not recommended for a flat roof, as shingles cannot be properly sealed if a roof has a pitch less than 2/12 inches, leading to water leaks.

What type of roofing is best for a low pitch roof?

Metal roofing systems are popular because of their longevity and durability. Rubber roofs are a top choice for flat or low pitched roofing as it adheres to the roofing materials below it and, when installed correctly, provides a watertight seal to the elements.

Chart: Standard Roof Pitch to Degrees Conversion

Roof Pitch to Degrees Conversion
2.5-in-12 11.77°

What does a 2 12 roof pitch look like?

A 2/12 roof slope means your roof has 2 inches of vertical drop for every 12 inches of horizontal distance. Simply put, it’s a shallow roof. That means the roof doesn’t shed water as easily as steeper roofs, which is why choosing the right type of roofing material is so important.
