Low Pitch Low Slope Metal Roof

It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too.

Low pitch low slope metal roof.

The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. 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.

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. The minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot. Low slope metal roofs require less material which reduces the overall load on the building s structure.

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. Minimum metal roof slope depends on the roof profile building design climate and site location. The metal roof minimum slope doesn t stray far from other building with different material. 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.

Available in 12 16 and 18 widths tite loc and tite loc plus panels can be produced in 22 and 24 gauge steel or 032 and 040 aluminum.
