Low slope roof requirements.

Regardless the international building code ibc chapter 15 includes the following requirements for minimum slopes for metal roof panels. Low slope and steep slope roofing systems have different industry standard testing requirements. The minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot. Lapped nonsoldered seam metal roofs without applied lap sealant must have a minimum roof slope of 3 12 25 slope.

An ssr may be installed on a roof down to 1 4 in. Lapped nonsoldered seam metal roofs with applied lap sealant must have a minimum roof slope of 1 2 12 4 slope. The roofing safety zones. Solar reflectance is a measure of the surface s ability to stay cool in the sun by reflecting solar radiation and emitting ther.

On 12 2 slope. Anything above that will require you to put out higher cost because they are already considered as higher pitch. During this test the roof panel system is completely submerged under six inches of water for. The standard of lower pitch actually ranges between 1 12 to 5 12.

Low slope metal roof systems are tested to astm e2140 standards a water penetration test evaluating the resistance of roof panels vertical seams. Low slope roofs in climate zones 1 3 are required to meet minimum roof reflectance and emittance provisions sometimes referred to as cool roofs.
