Lead flashing repair across Reading
We serve Reading from our base in Thatcham.
What happens on the day
A clear visual check of roof flashings identifies whether leaks stem from metal splits, failed pointing or displaced under-tile details.
- Access and Surface InspectionWorking from secured ladders and roof ladders, the condition of current leadwork is assessed around all stacks, dormers and parapet walls to locate splits, slipped aprons or failing mortar bonds.
- Adjacent Tile and Batten ChecksTiles and slates sitting beneath the apron or step flashings are lifted where necessary to ensure water has not rotted the underlying battens or penetrated through the secondary weather barrier.
- Substrate and Chase PreparationThe depth of existing brick mortar joints is checked to plan the raking out of old mortar, ensuring newly dressed lead can be mechanically held with rolled lead wedges rather than surface paste.

Questions About Lead Flashing Repairs
Can cracked lead flashing simply be sealed with sealant or tape?
Surface tape and mastics degrade rapidly under ultraviolet light and temperature changes. While temporary patches might briefly divert water, cracked or fatigued lead must be renewed with fresh sheet metal to achieve a lasting seal.
Why does flashing split along long rear extensions?
Lead expands when warm and contracts when cold. When flashings on long wall runs or rear additions are fitted in single continuous strips without expansion laps, the metal pulls against its fixings until it tears.
Is a cement fillet an acceptable alternative to lead flashing?
A cement fillet bridges two different materials that move at different rates. The mortar invariably cracks along the joint line, drawing rainwater behind the fillet and down into the brickwork, making lead the superior method.
Why is patination oil applied to new lead flashing?
New lead oxidises when exposed to rainwater, producing a white powder. Patination oil seals the surface while it cures, preventing unsightly white streaks from washing down over slates, tiles and brickwork.
How do I tell if a ceiling leak is coming from chimney flashing?
Damp patches, staining or peeling wallpaper appearing on chimney breasts or high ceilings near exterior abutment walls following heavy rain typically point to failed flashing or loosened brickwork mortar joints.
