The minimum roof slope allowed by code for any type of roof is in 12 applicable only to coal tar pitch roof systems.

Minimumee slope steel roof.

The minimum pitch for metal roof shingles and lapped non soldered panels is 3 12. Minimum metal roof slope depends on the roof profile building design climate and site location. The minimum pitch for roll roofing is 2 12 or 2 inches rise to 12 inches run. To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope.

Low slope metal roofs require less material which reduces the overall load on the building s structure. The minimum pitch for metal roofing varies depending on the profile of the metal. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. The short simple answer is 2 12 has traditionally been considered the absolute minimum acceptable roof slope suitable for asphalt shingles.

The minimum roof slope for metal roof panels depend on 3 different scenarios. Minimum pitch for metal roof. For low slope metal roofs under 12 that are nearly flat modified bitumen roofing thermoset and. Roof pitch is the degree of building s roof slope.

The minimum roof slope for metal roofs is dependent upon the roof profile. Lapped nonsoldered seam metal roofs with applied lap. Amongst many decisions one has to make when designing a metal building determining metal roof minimum slope is one of them. Profile in the context of metal roofing means the shape that the sheet of metal is bent into to form the panels.

With regards to metal roofing the profile refers to the shape adopted by the metal sheets when they are bent to form the panels. They provide excellent weather resistance great value and now more than ever a tremendous range of beautiful designs and color blends. 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. Lapped nonsoldered seam metal roofs without applied lap sealant must have a minimum roof slope of 3 12 25 slope.

The minimum pitch for a standing seam metal roof is 1 4 or 3 inches rise to 12 inches run. Panels joined with an applied lap sealant can go as low as 12. After that the miimum pitch for metal panels depending on the methods used to join the panels. Typically large footprint single story.

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. Minimum roof pitch for metal building. According to the 2012 international building code 1507 4 2 deck slope minimum slopes for roof panels need to comply with the following. The following table provides the minimum required allowable roof slope for each type of roofing material mentioned in the code.
