Description
Counter Flashing
Counter flashing is a key component in roof-to-wall and roof-to-chimney intersections, providing a secondary line of defense against water infiltration. It is installed over step or base flashings and either inserted into a reglet or embedded in masonry joints for a secure, watertight seal. Its main function is to shield the upper edge of primary flashings from weather exposure, ensuring long-term protection of vertical transitions.
Features:
-
Protects base and step flashings from wind-driven rain and water intrusion
-
Typically embedded in masonry or secured into a reglet channel
-
Ensures long-term waterproofing at roof-to-wall connections
-
Clean finish for both residential and commercial applications
Commonly Paired Flashings:
-
Reglet Flashing – Provides a recessed channel for secure counter flashing installation
- Step Flashing – Works underneath counter flashing along sloped roof intersections
-
End Wall Flashing – Complements the system for full moisture control on vertical surfaces
