Low Pitch Low Slope Metal Roof

A low slope roof is defined in the industry as a roof that has a pitch equal to 3 12 or less.

Low pitch low slope metal roof.

Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. 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. 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. Low slope metal roofs require less material which reduces the overall load on the building s structure.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. At sheffield metals we also recognize low slope as 3 12 and below. The metal roof minimum slope doesn t stray far from other building with different material.

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 minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot. 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.
