Metal Roof On Low Pitch Roof

The corrugated metal roof minimum slope is 5 degrees.

Metal roof on low pitch roof.

Low slope metal roofs provide years of low cost low maintenance performance. Low slope metal roofs require less material which reduces the overall load on the building s structure. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. At sheffield metals we also recognize low slope as 3 12 and below.

Determining which panel is the right choice for the slope on your project will depend on the manufacturer s minimum slope factor for that specific panel profile. It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this.

Most structural metal panel roof systems are designed to resist the passage of water at laps and other joints as sealant or anti capillary designs can be used in the seams. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. Minimum metal roof slope depends on the roof profile building design climate and site location. But the taller profiles like standing seam and pbr shown below can be installed on roofs with as low as 1 4 or 1 2 in 12 pitch.

Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. A low slope roof is defined in the industry as a roof that has a pitch equal to 3 12 or less. Minimum pitch for metal roof 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.
