Panel profile
The shape of the ribs or seams. Exposed-fastener and concealed-fastener systems have different attachment and maintenance requirements.
HOMEOWNER GUIDE / METAL ROOFING
Understand metal roofing.
What the parts do, what the terms mean and what to ask before work begins.
Gauge & substrate
Gauge describes metal thickness; the metal and protective coating also matter. Ask for the exact panel specification.
Finish & color
Compare the actual coating, finish and sample, not only a color name. Confirm which written finish warranty applies.
Closures
Profile-shaped components used at specified details to help close panel openings. Placement depends on the panel system.
Fasteners & clips
The components securing panels to the supporting structure. Ask how movement, attachment and maintenance are addressed.
Ridge, valley & wall trim
Formed metal details at roof transitions. Ask the estimate to include each transition and penetration, not just the panels.
