A roof leak around a vent or wall transition may require more than new sealant. The contractor should inspect the flashing sequence, fasteners, surrounding shingles, and interior evidence.

Why flashing failures are difficult to see
Water can enter above the visible stain and travel along decking or framing. The inspection should follow the likely water path and document the affected transition.
A durable repair scope
The repair should name the flashing or vent component, surrounding materials, and any underlayment or decking work. Surface sealant alone is not a universal solution.
- Trace the water path
- Inspect vent and wall details
- Replace failed flashing where needed
- Verify the repair after weather
