Standing Metal Seam Roof Over Low Slope

Central loc is a 3 high clip standing seam most chosen for low slope commercial applications.

Standing metal seam roof over low slope.

Metal roofing it s a general term that covers a broad scope of roofing options products and choices. Standing seam is the metal roof profile that has been gaining more popularity nowadays due to its clean and modern looks. Structural metal panel roof systems can be used for low slope roofs because of their hydrostatic or water barrier characteristics. And because of their interlocking or active fastening systems metal roof panels are designed to meet the requirements of astm e1592 ul 580 ul1897 and other severe wind and uplift tests.

You can often see such examples of use over metal decks. Central loc is designed for installation over open framing and solid decking and designed for use on slopes as low as 0 25 12. When someone references metal roofing he or she could be talking about shingles or tiles made of metal an exposed fastener roofing system that is common for agriculture buildings or maybe even a standing seam metal roofing system. 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.

A floating design allows for longer panels and end lapping as needed. Standing seam manufactures allow applications of metal coverings on slopes of 12 or even more. Speaking about standing seam metal roof slope it is a general and a self evident knowledge that the steeper it is the faster it is for snow rain or drain to come down the roof. Unlike non metal systems which require an underlying substrate or deck low slope metal roofs can be applied directly over bar joists or purlins.

Low slope metal roofs require less material which reduces the overall load on the building s structure. There is only one category of metal roof systems used in low slope applications structural metal panel. 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. Their fasteners are either concealed or screwed at the top of a ridge which makes them less likely to leak.

When looking at metal roofing panel you will need to consult with the manufacturer to ensure that the metal panel you selected will work for your application. Low slope metal roofs have simple geometries and are easier and less expensive to install that medium to steep slope roofs. 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.

There are several benefits of a low slope roof. It is important to note structural metal panel roof systems can be used for steep slope roof assemblies too.
