Drexel Metals

Standing seam metal — inspector's-eye notes on install spec, warranty requirements, and what typically gets skipped on NM installs.

Training attended

Snap-lock and mechanical seam panel systems, DrexTech underlayments — cold-climate + high-UV spec

Southwest regional

Owner-attested attendance. Drexel Metals does not typically issue individual certificates for product-knowledge sessions. Listed as training attended, never as certification.

What we check on a Drexel Metals install

  • Panel gauge (24ga vs 26ga) and coating system (PVDF vs SMP) drive lifespan.
  • Clip spacing and attachment method — snap-lock vs mechanical seam matters for wind.
  • Butyl tape at every panel end lap and hip/ridge closure.
  • Oil-canning is cosmetic on cheap gauges — spec heavier metal on visible planes.
  • Underlayment: high-temp synthetic is mandatory under metal in NM sun.

Questions to ask any contractor bidding Drexel Metals on your roof

  1. Are you a Drexel Metals-authorized installer? Can you register the manufacturer's system warranty on my roof?
  2. Which Drexel Metals product line are you installing? What's the exact spec — nailing pattern, underlayment, accessories?
  3. Will you supply photos of critical details (valleys, penetrations, flashings) before dry-in and after tear-off?
  4. Does the Drexel Metals warranty on this bid cover material only, labor + material, or full system with workmanship?
  5. What's your written policy if a Drexel Metals warranty claim is denied later because install spec wasn't met?
