The traditional metal roof types such as 5v crimp shown above and corrugated are rated by the manufacturers for use down to a 3 12 pitch three inches of vertical rise for every foot of horizontal run.

Lowest pitch standing seam metal roof.

The standard of lower pitch actually ranges between 1 12 to 5 12. However there are many mechanically seamed standing seams that are very appropriate for lower pitch roofs usually down to about 1 4 12 most flat seam products will have soldered seams to make them watertight even on a flat roof. 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. Anything above that will require you to put out higher cost because they are already considered as higher 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. In 12 0 25 in 12 1 19 metal.

The panels have been designed for application over a wide variety of substrates on roof slopes as low as 1 2 12 pitch. Sunday august 5 2018.

On low pitches they can be installed manually or otherwise mechanical standing seam can be used to guarantee the connection will not come apart at the seams. Most residential metal roofs require at least a 3 12 roof pitch and have no maximum roof pitch. That means there is at least 3 of vertical rise to the roof slope for every 12 it goes back horizontally. Basically low slope standing seam metal roof is the kind of rooftop used on low slope pitches.

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. Minimum slope requirements depending on the roof profile there are minimum roof slope requirements for each panel which need to be considered. In 12 0 5 in 12 2 39 metal. Manufacturers specify a minimum pitch for each of the profiles they offer and sometimes they can be installed at a lower pitch if special underlayment or installation procedures are followed.
