Metal Roofing — FAQs

Standing seam vs R/PBR — which is best?

Standing seam uses concealed clips for premium weather-tightness and aesthetics; R/PBR is economical with faster installs. We recommend based on budget, slope, exposure, and visibility.

Can you retrofit metal over my existing roof?

Yes—engineered sub-purlins/hat channels with flute fill and ISO allow metal-over-metal or even metal-over-flat-roof retrofits, reducing tear-off and disruption when conditions permit.

PVDF (Kynar®) vs SMP finishes — what’s the difference?

PVDF/Kynar® delivers top-tier fade/chalk resistance for long-term color retention; SMP is cost-effective with solid performance. We’ll spec the right finish for your environment.

Do I need snow guards or expansion joints?

In snowy climates, snow retention protects entrances and gutters. Long runs or complex geometries often require expansion details to manage thermal movement and prevent oil-canning.
