Low Pitch Standing Seam Metal Roof

But the taller profiles like standing seam and pbr shown below can be installed on roofs with as low as 1 4 or 1 2 in 12 pitch.

Low pitch standing seam metal roof.

The minimum pitch is typically 3 12 meaning the roof should rise 3 inches for every 12 inches of horizontal foot. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. When we say standing seam what is essentially meant is that the structure is made of overlapping interlocked panels that are arranged and secured vertically. Their fasteners are either concealed or screwed at the top of a ridge which makes them less likely to leak.

Lapped nonsoldered seam metal roofs with applied lap sealant must have a minimum roof slope of 1 2 12. A 3 degree roof pitch means just over 50mm in every metre so over 3 metres you only have 150mm to play with. The standard of lower pitch actually ranges between 1 12 to 5 12. Sig zinc and copper recommend that the minimum pitch for a standing seam zinc roof is five degrees with an absolute minimum of 3 degrees.

Having a proper job specific safety plan with 100 percent tie off rule is a good recommendation. Low slope structural roofing generally used on roof pitches ranging from 12 to 3 12 consists of interlocking panels commonly called standing seam roofing that run vertically along the roof surface. Basically low slope standing seam metal roof is the kind of rooftop used on low slope pitches. We recommend 5 degrees however due to site conditions and execution.

Anything above that will require you to put out higher cost because they are already considered as higher pitch. In this situation safety compliance for the crew is critical as the technicians will be working with no decking or sheathing beneath them. Lapped nonsoldered seam metal roofs without applied lap sealant must have a minimum roof slope of 3 12. These panels generally come with a painted mill finish or a clear acrylic finish.
