Min Metal Roof Slope

Corrugated metal roofing has the same minimum pitch.

Min metal roof slope.

With regards to metal roofing the profile refers to the shape adopted by the metal sheets when they are bent to form the panels. The minimum roof slope for metal roof panels depend on 3 different scenarios. The minimum roof slope for metal roofs is dependent upon the roof profile. Low slope metal roofs require less material which reduces the overall load on the building s structure.

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. Minimum metal roof slope depends on the roof profile building design climate and site location. 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 three in twelve or 3 12 3 inches vertically per 12 inches horizontally.

To get the minimum pitch for a metal roof the vertical rise per foot is divided by the horizontal slope. Lapped nonsoldered seam metal roofs with applied lap. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Amongst many decisions one has to make when designing a metal building determining metal roof minimum slope is one of them.

It determines how many inches the roof should rise for every 12 inches expanding on the horizontal side. Minimum pitch for metal roof. Roof pitch is the degree of building s roof slope. Typically large footprint single story.
