Metal Roof Panel Types
Standing Seam (24")
Premium metal roofing with concealed fasteners. Most common in residential. Lifespan 40-70 years.
Corrugated (36")
Exposed-fastener panels. Budget-friendly, common for barns and outbuildings. Lifespan 25-40 years.
R-Panel (26")
Similar to corrugated with a ribbed profile. Good for commercial and industrial. Lifespan 30-50 years.
