What gauge is standing seam metal roofing?

best-metal-roofing-gauge

The vast majority of standing seam metal roofing jobs are 24 gauge steel. It’s a premium roofing system that’s expected to last 40 plus years. The components must be designed to work as a whole. Standing seam roofing panels are the most expensive panels and use the best paint system. It wouldn’t make sense to use a light gauge steel for minimal savings and lesser performance.

What is the difference between standing seam vs corrugated metal roofs?

standing-seam-vs-exposed-fastener-video

The biggest difference between these two classic metal roofing systems is the method of attachment. Standing seam panels are a concealed fastener system which means the fasteners don’t penetrate the face of the panel during installation and they’re not visible. Corrugated panels are an exposed fastener panel, meaning that you need to drill a screw hole through the panel to fasten it to the structure.

What is oil canning on a metal roof?

stiffening-ribs-striations-thumbnail

Have you ever seen a metal roofing material that looked like it was wrinkled? This is known as oil canning and it's common on standing seam metal roofs.

Oil canning on a standing seam metal panel is an aesthetic issue only. Striations, stiffening ribs, and clip relief can disguise the appearance of oil canning on your metal roofing panels.

What Is A Standing Seam Metal Roof?

Standing seam metal roofing has a flat area in the middle and raised vertical seams at both ends. It's a concealed fastener system, meaning that the fasteners are not visible or exposed to the weather. It's water-tight and long lasting, but it's also an expensive panel system.

What Is Snap Lock Standing Seam Metal Roofing?

Snap Lock is a concealed fastener standing seam metal roofing that has a male and female leg that snaps together. It's available as a clip fastened or nail flange fastened panel.
