Low Slope Standing Seam Metal Roofing Systems

138t 238t these are symmetrical standing seam systems that are ideal for new or retrofit applications.

Low slope standing seam metal roofing systems.

There are some opinions that standing seam metal roof minimum slope is 12 but it increases the possibility of leaking on the few first days of snow arrival. Mcelroy metal offers patented 138t and 238t recover systems that are designed to retrofit over existing metal or shingle roofs. Keep in mind that because a mechanically locked system requires seaming it might not look as clean as a snap lock profile. 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.

The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. Low slope roofs are not totally flat their roof slope generally ranges from 1 4 12 to 3 12. Instaloc offers a snap together standing seam system that can be used with solid decking. 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.

It features a low profile seam that makes instaloc a wonderful choice for light commercial and residential applications. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. In country with heavy snow and tough winter days the metal roof minimum slope is recommended to be 1 12. These panels generally come with a painted mill finish or a clear acrylic finish.

Typically large footprint single story warehouses and pre engineered metal buildings will utilize low slope metal roof systems. However a mechanical profile will perform better which is more important. There is only one category of metal roof systems used in low slope applications structural metal panel. 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. Minimum metal roof slope depends on the roof profile building design climate and site location. If you want a metal roof and it s a low sloping roof you should go with a mechanical lock profile. It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too.
