Low Slope Roofing Metal

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

Low slope roofing metal.

In country with heavy snow and tough winter days the metal roof minimum slope is recommended to be 1 12. An ssr has side joints between the roof panels that are arranged in a vertical position above the roof line. The post and purlin system adds a continuous base zee which enables it to be installed over steel bar joists that are spanning perpendicular to the new roof slope. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 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. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. 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. At sheffield metals we also recognize low slope as 3 12 and below.

Low slope metal roofs require less material which reduces the overall load on the building s structure. There is only one category of metal roof systems used in low slope applications structural metal panel. Low slope metal roofing materials include perimeter edge flashing soffit panels drainage and es 1 rated edge systems from sheet metal supply.

There are some opinions that standing seam metal roof minimum slope is 12 but it increases the possibility of leaking on the few first days of snow arrival. A lightweight roofing system also places fewer demands on a building s structural support system an important consideration in earthquake prone areas. Rain gutters guards downspouts.

Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems.
