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 roofing.
Low slope metal panel roofing may be a standing seam roof ssr through fastened roof tfr or insulated metal panel imp roof.
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.
An ssr has side joints between the roof panels that are arranged in a vertical position above the roof line.
Corrugated aluminum panels most buildings with metal roofing system are using corrugated roofing type.
Low slope metal roofs require less material which reduces the overall load on the building s structure.
During this test the roof panel system is completely submerged under six inches of water for approximately six hours.
Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems.
The corrugated metal roof minimum slope is 5 degrees.
A lightweight roofing system also places fewer demands on a building s structural support system an important consideration in earthquake prone areas.
It is the recommended slope as there is no guarantee if you opt for flatter pitch than this.
