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.

Low pitch low slope metal roof.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. The minimum pitch for metal roofing varies depending on the profile of the metal. Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels.

The pitch is measured in inches of vertical rise per foot of horizontal run and the 5v crimp profile shown above requires a minimum slope of three in twelve or 3 12 3 inches vertically per 12 inches horizontally. Can metal roofing be used on a low slope pitch roof. 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. Low slope metal roofs have been a preferred roof covering for commercial institutional and industrial buildings for years because of their ability to protect against the elements to allow water to drain away from the roof surface and to keep building contents and occupants dry and comfortable.

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

Minimum metal roof slope depends on the roof profile building design climate and site location. A low slope roof is defined in the industry as a roof that has a pitch equal to 3 12 or less. At sheffield metals we also recognize low slope as 3 12 and below. Tite loc and tite loc plus panels are factory formed to length and field seamed to a 90 lock tite loc or a 180 lock tite loc plus.

Sunday august 5 2018 the traditional metal roof types such as 5v crimp shown above and corrugated are rated by the manufacturers for use down to a 3 12 pitch three inches of vertical rise for every foot of horizontal run. 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.
