I have found the proper roof but the underlayment options and guidance has been scattered.

Metal roof on low pitch roof.

Before you decide on going with a metal roof. 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. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs.

A low sloped roof requires less roofing material which reduces the weight load placed on the structure. My roof at lowest is 75 12. Low slope metal roofs require less material which reduces the overall load on the building s structure. Minimum pitch for corrugated metal roof corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch.

At sheffield metals we also recognize low slope as 3 12 and below. A metal roof mechanically seamed crimped and butyl injected at the seams designed to handle low slopes as low as 5 12. The other side is 2 12. 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 corrugated metal roof minimum slope is 5 degrees. Typically a low slope metal roofing system weighs between 40 to 135 pounds per 100 square feet making them one of the lightest and easiest roofing materials to install. The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. The flatter the roof the more likely that a metal roof will leak at the seams.

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. It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. That s a definite possibility if the roof has a very shallow pitch. Minimum metal roof slope depends on the roof profile building design climate and site location.

Can metal roofing be used on a low slope pitch roof.
