Metal Roof On Low Pitch Roof

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.

Metal roof on low pitch roof.

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. 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. The corrugated metal roof minimum slope is 5 degrees.

It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too. Because of the shallow height of the undulating ridges of the 5v and corrugated profiles and the use of exposed metal fasteners to screw the metal to the roof deck they are limited to a slope that will shed rain quickly. Low slope metal roofs provide years of low cost low maintenance performance. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12.

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. At sheffield metals we also recognize low slope as 3 12 and below. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. Minimum metal roof slope depends on the roof profile building design climate and site location.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. Low slope metal roofs require less material which reduces the overall load on the building s structure.
