/ About Flashing

What is Roof Flashing?

Flashing is metal or other material installed around roof penetrations (vents, chimneys, skylights) to direct water away from the opening.

Why Flashing is Critical

Anywhere pipes, vents, or chimneys go through your roof, water can enter if flashing is improper or missing. Flashing is the transition between the roof and the penetration—without it, water leaks directly into your home.

Common Penetrations Requiring Flashing

  • Roof vents and exhaust ducts
  • Chimneys and flue pipes
  • Skylights and roof windows
  • Plumbing vent stacks
  • HVAC vents and intake
  • Roof-mounted equipment
