Re: Minimum Pitch For Metal Roofing The minimum slope depends on the exact system and profile. 1. There are "low-slope" profiles with hidden fasteners, that can go as low a 1:12 without using solding. Lapped, nonsoldered-seam metal roofs without applied lap sealant must have a minimum roof slope of 3:12 (25% slope).

After that, the miimum pitch for metal panels depending on the methods used to join the panels . The minimum pitch for roll roofing is 2:12, or 2 inches rise to 12 inches run. Profile, in the context of metal roofing, means the shape that the sheet of metal is bent into to form the panels. The minimum pitch for a standing seam metal roof is 1:4, or 3 inches rise to 12 inches run. Most metal roofs will have minimum pitches of three in twelve, but this might sometimes go down depending on whether there are special installation procedures issued by the manufacturer regarding that particular roofing material. Panels joined with an applied lap sealant can go as low as :12. What is the minimum pitch/slope for a metal roof? The pitch is measured in inches of vertical rise per foot of horizontal run, and the “5V-crimp” profile shown above requires a minimum slope of …

The minimum roof slope for metal roof panels depend on 3 different scenarios. The minimum pitch for metal roofing varies depending on the profile of the metal. That is a 14 degree angle. Metal Roof Panels Minimum Roof Slope (Roof Pitch) | R905.10.2. Most residential metal roofs require at least a 3:12 roof pitch and have no maximum roof pitch. According to the 2012 International Building Code (1507.4.2 Deck slope), minimum slopes for roof panels need to comply with the following: The minimum slope for lapped, non-soldered seam metal roofs without applied lap sealant shall be three units vertical in 12 units horizontal (25-percent slope). That means there is at least 3” of vertical rise to the roof slope for every 12” it goes back horizontally. To get the minimum pitch for a metal roof, the vertical rise per foot is divided by the horizontal slope. Functional Pitch The minimum pitch for metal roof shingles and lapped, non-soldered panels is 3:12.
