Sloped Metal Roofing

The corrugated metal roof minimum slope is 5 degrees.

Sloped metal roofing.

Minimum metal roof slope depends on the roof profile building design climate and site location. Metal roof slope is expressed by a ratio indicating the roof pitch which notes the vertical rise of the roof in inches for every 12 inches the roof runs horizontally in other words dividing the vertical rise and its horizontal span. That s why your best bet will be to use some variation of a mechanically seamed metal roof system specifically a double lock profile. Low slope metal roofs require less material which reduces the overall load on the building s structure.

Low slope metal roofs provide years of low cost low maintenance performance. The most common slopes are. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Final thoughts on low slope metal roofing the bottom line is that you want to install a standing seam metal roof profile that will provide the most protection for your low slope project.

Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. Because low slope roofs drain water more slowly than moderate or steep sloped roofs systems such as slate or asphalt shingles that rely on mechanical drainage for successful performance are not used. Corrugated roofing is an amazing choice for conventional pitched roof despite having the severe limitation about the pitch. Low slope metal roofs have been a preferred roof covering for commercial institutional and industrial buildings for years because of their ability to protect against the elements to allow water to drain away from the roof surface and to keep building contents and occupants dry and comfortable.
