A stainless steel chimney roof flashing is a weatherproof metal flashing system installed around chimney penetrations to prevent water leakage between the chimney structure and the roof surface.

A stainless steel chimney roof flashing is:

  • A custom-shaped stainless steel flashing component installed around a chimney where it passes through a roof
  • Designed to create a waterproof transition between roofing materials and chimney structures
  • Available as base flashing, step flashing, counter flashing, and custom chimney flashing assemblies

It is used to:

  • Prevent water intrusion around chimney penetrations
  • Protect roof structures, insulation, and interior spaces from moisture damage
  • Improve chimney system weather resistance
  • Extend the service life of roofing and chimney components
