Metal Roof For Low Pitch

Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics.

Metal roof for low pitch.

Low slope metal roofs require less material which reduces the overall load on the building s structure. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Low slope metal roofs provide years of low cost low maintenance performance. For low slope metal roofs under 12 that are nearly flat modified bitumen roofing thermoset and thermoplastic single ply are approved and recommended.

A low slope roof is defined in the industry as a roof that has a pitch equal to 3 12 or less. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. There are several benefits of a low slope roof. 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.

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. A low slope roof is one whose slope is less than 3 12. Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this.

Minimum metal roof slope depends on the roof profile building design climate and site location. After that the miimum pitch for metal panels depending on the methods used to join the panels. There is only one category of metal roof systems used in low slope applications structural metal panel. 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.

When looking at metal roofing panel you will need to consult with the manufacturer to ensure that the metal panel you selected will work for your application. Panels joined with an applied lap sealant can go as low as 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. The corrugated metal roof minimum slope is 5 degrees.

At sheffield metals we also recognize low slope as 3 12 and below.
