Low Slope Metal Roofing

Low slope metal panel roofing may be a standing seam roof ssr through fastened roof tfr or insulated metal panel imp roof.

Low slope metal roofing.

It is the recommended slope as there is no guarantee if you opt for flatter pitch than this. Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. A lightweight roofing system also places fewer demands on a building s structural support system an important consideration in earthquake prone areas. 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.

Low slope metal roofs require less material which reduces the overall load on the building s structure. Typically low slope metal roof systems vary in weight from 40 to 135 pounds per 100 square feet making them among the lightest roofing products and the easiest to install. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Low slope metal roof systems are tested to astm e2140 standards a water penetration test evaluating the resistance of roof panels vertical seams.

Minimum metal roof slope depends on the roof profile building design climate and site location. 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. Corrugated aluminum panels most buildings with metal roofing system are using corrugated roofing type.
