Flashing Failing? Stop Leaks at the Joints.
Flashing is the thin seal that protects the most leak-prone parts of your roof — around chimneys, valleys, and where the roof meets a wall. When it cracks or lifts, water gets straight in. Tell us where the problem is and where your property is so we can help.

Roof Flashing Repairs at Vulnerable Joints
Flashing is the unsung hero of a weather-tight roof. Wherever the roof covering is interrupted — at a chimney, in a valley, against a wall, around a pipe — flashing forms the seal that keeps water out of the join. It's usually lead, sometimes other metals or modern membranes, and it fails over time.
Flashing cracks as it ages, lifts in high winds, and pulls away from mortar as it weathers. Once the seal breaks, water runs down the flashing and straight into the roof. Repairing or renewing the flashing restores the seal at the points where roofs most often leak.
Common Flashing Problems
Cracked, split or lifted lead flashing
Flashing pulled away from chimney mortar or brickwork
Damp patches on walls or ceilings near a chimney
Water running down a valley during heavy rain
Stains where the roof meets an adjoining wall
Mortar crumbling where flashing is bedded in
What's Involved in Flashing Repair?
1. Locate the Leaking Joint
Tell us where you're seeing damp or where the flashing looks damaged, and where your property is.
2. Inspect the Flashing
The flashing is checked at the chimney, valley or wall joint to find where the seal has failed.
3. Repair or Renew
Cracked flashing is repaired or renewed — lead dressed back into place or a new section cut and fixed securely.
4. Reseal the Joint
The join between flashing, mortar and tiles is sealed so water runs off rather than in.
Why Repair Flashing Promptly?
Stop Leaks at the Source
Most roof leaks start at a failed flashing. Repairing it stops water getting in at the most vulnerable joints.
Protect Chimneys and Walls
Flashing keeps water out of chimney stacks and the tops of walls where it can cause serious damage.
A Targeted, Cost-Effective Fix
Renewing a section of flashing is far cheaper than repairing the water damage a leaky joint can cause.
Keep Valleys Clear
Sound valley flashing carries water down the roof instead of letting it pool and seep through.
