Low Slope Metal Roof Detail

Minimum metal roof slope depends on the roof profile building design climate and site location.

Low slope metal roof detail.

Low slope metal roofs require less material which reduces the overall load on the building s structure. That includes soldered metal roofing or synthetic membranes. 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. The roof clips or hold down clips are concealed in the seam of the panel.

Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. If the ssr is attached directly to open framing it is typically designed to expand and contract and must be allowed to float. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. A lightweight roofing system also places fewer demands on a building s structural support system an important consideration in earthquake prone areas.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. By low slope roofing we mean any roof that is pitched at less than 4 inches of rise in 12 inches of run or 4 12 pitch. 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. 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.
