Low Pitch Standing Seam Metal Roof

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.

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. In this situation safety compliance for the crew is critical as the technicians will be working with no decking or sheathing beneath them. The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. We recommend 5 degrees however due to site conditions and execution.

A 3 degree roof pitch means just over 50mm in every metre so over 3 metres you only have 150mm to play with. Low slope metal roofs are often installed as structural standing seam panels over open framing. Coal tar built up roofs can be installed on a roof pitch of 1 8 12 or greater. Available in 12 16 and 18 widths tite loc and tite loc plus panels can be produced in 22 and 24 gauge steel or 032 and 040 aluminum.

The standard of lower pitch actually ranges between 1 12 to 5 12. Anything above that will require you to put out higher cost because they are already considered as higher pitch. Their fasteners are either concealed or screwed at the top of a ridge which makes them less likely to leak. 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.

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 with applied lap sealant must have a minimum roof slope of 1 2 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. These panels generally come with a painted mill finish or a clear acrylic finish.
