Flashing Repairs

Flashing seals the joints where your roof meets walls, chimneys, dormers and rooflights, and is traditionally lead. When flashing cracks, lifts or comes away, water gets into these junctions and can cause damp inside. A roofer can re-dress, repair or replace lead flashing, or use an alternative flashing material where that suits the roof.

Why Choose Flashing Repairs?

  • Stops water getting in at chimneys, walls and roof junctions
  • Helps prevent damp patches on chimney breasts and upstairs walls
  • Often cheaper than repairing the internal damage a leak causes
  • A chance to check other flashing points at the same time

Frequently Asked Questions

How do I know if my flashing needs replacing?

Signs include damp patches on walls near the roofline, water stains on chimney breasts, visible gaps or lifted edges on the flashing, and crumbling mortar where flashing meets brickwork. If you notice any of these, it is worth having a roofer take a look before the damp spreads.
