Common flashing locations
- Chimneys
- Sidewalls and headwalls
- Roof valleys
- Plumbing vents and other penetrations
- Skylights and similar roof openings
Reuse or replace?
The appropriate treatment depends on condition, compatibility, installation details, and the project scope. Ask the provider to state what flashing will be replaced, reused, or modified.
Details matter
Roofing material alone does not determine performance. Transitions and penetrations must be integrated with the roofing system.
Put it in writing
If flashing work is important to the project, make sure the proposal describes it rather than relying only on a verbal explanation.
