Damaged Roof Flashing
Flashing seals the joins where a roof meets walls, chimneys and windows. When it fails, water gets straight in.
Possible causes
- Lead that has split from thermal movement
- Lead theft
- Mortar pointing that has fallen out of the wall chase
- Cheap substitute materials failing
Warning signs
- Lifted or missing lead
- Gaps where flashing meets brickwork
- Damp at junctions inside
How it's usually fixed
- Renewing leadwork to the correct code and lengths
- Re-dressing and repointing existing lead
- Replacing failed mortar fillets with lead
