Panel Profiles for Commercial Metal Roofs

Our commercial standing seam panels come in 24 or 22-gauge steel with a 70% Kynar 500 PVDF finish, and aluminum in .032 or .040 inch where a building's environment calls for it.

Snap-lock and mechanically seamed panels can be combined on one building when different roof areas call for different performance, such as a mechanically seamed profile on a low-slope section and snap-lock on the steeper planes.

A mechanically seamed profile is best for the lowest slopes and windiest sites we take on, because the folded, locked seam resists wind-driven water far better than a snapped seam.

A taller seam improves water and wind resistance because it holds the lock farther above the water running down the roof, which is why taller seams suit lower slopes and exposed sites.

We roll-form panels on site to the widths a commercial roof needs, generally from 12 to 18 inches, cutting each run to the building's exact dimensions rather than being limited to stock sizes.

A structural standing seam profile uses a taller, load-bearing rib that spans open purlins or bar joists directly, so it carries its own load without a solid deck beneath it.

A screw-down R-panel is the right choice for an economical, utilitarian building where exposed fasteners are acceptable, since it costs less than standing seam but does not float with thermal movement.

We can form panels to specific widths on site, so a profile can be matched to an architect's design or an existing roof instead of being limited to stock sizes.

The panel profile affects oil-canning because wider, flatter panels show waviness more than narrower ones, so we pair wider profiles with heavier gauge and optional striations to keep the surface flat.

The panel profile changes the cost because a screw-down R-panel roof costs less than a concealed-fastener standing seam roof, and a mechanically seamed profile costs more than snap-lock; we price it against the building's slope, exposure, and service-life needs.
