Minimum Slope Corrugated Metal Roof

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12.

Minimum slope corrugated metal roof.

Minimum pitch for corrugated metal roof just like other metal roofs the minimum pitch for a corrugated metal roof largely depends on the profile of the roof. In most occasions a pitch of three in twelve is preferred but this should also take into consideration the manufacturer s recommendations as well the unique condition of the corrugated metal roof. The minimum slope for lapped non soldered seam metal roofs without applied lap sealant shall be three units vertical in 12 units horizontal 25 percent slope. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems.

The corrugated metal roof minimum slope is 5 degrees. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. Lapped nonsoldered seam metal roofs with applied lap sealant must have a minimum roof slope of 1 2 12 4 slope. Lap sealants shall be applied in accordance with the approved manufacturer s installation instructions.

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. Minimum metal roof slope depends on the roof profile building design climate and site location. Lapped nonsoldered seam metal roofs without applied lap sealant must have a minimum roof slope of 3 12 25 slope. Low slope metal roofs require less material which reduces the overall load on the building s structure.

The minimum slope for lapped non soldered seam metal roofs with applied lap sealant shall be one half unit vertical in 12 units horizontal 4 percent slope. Corrugated metal roofing has the same minimum pitch.
