Metal Roof On Low Pitch Roof

It is the recommended slope as there is no guarantee if you opt for flatter pitch than this.

Metal roof on low pitch roof.

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. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. 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. Low slope metal roofs require less material which reduces the overall load on the building s structure.

Low slope metal roofs provide years of low cost low maintenance performance. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. 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.

A low slope roof is defined in the industry as a roof that has a pitch equal to 3 12 or less. 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. 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. It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too.

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. 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.
