Roof Flashing Repairs
Flashing seals the joints where a roof meets something else. When it fails, water finds its way straight in.
About this service
Roof Flashing Repairs from Master Roofing & Flat Roofing
Flashing is used wherever the roof covering meets another surface — a chimney, a side wall, a dormer, a valley or a vent pipe. These junctions are some of the most vulnerable points on any roof.
Lead can split, lift or lose its mortar pointing over time, and some older roofs rely on cement fillets that crack. We repair or renew flashing so the junction sheds water as intended.
Where flashing problems occur
- Around chimney stacks
- Where a lean-to or extension roof meets a wall
- Along valleys between roof slopes
- Around soil pipes, vents and roof windows
- At dormer cheeks and fronts

Benefits and practical considerations
