Metal roofing

Metal Roof Replacement Guide

Metal roofing can be a long-term option, but “metal roof” describes several different systems. The panel type, coating, substrate, fastening method, trim details, and installer experience all matter.

Common residential metal systems

Standing seam and exposed-fastener systems have different details, appearance, maintenance considerations, and costs. Ask exactly which system is being proposed.

Questions for a metal-roof proposal

  • Panel profile and metal thickness or gauge where relevant
  • Paint or protective coating system
  • Fastening method
  • Underlayment and ventilation
  • Trim, valleys, transitions, and penetrations
  • Warranty coverage for material and workmanship

Roof geometry affects complexity

Dormers, valleys, chimneys, skylights, and numerous penetrations can add considerable detailing to a metal roof installation.

Compare total installed systems

A metal roof estimate should be evaluated as a complete installed system, not simply by the cost of the metal panels.
