Faulty leadwork around the chimney is behind most roof leaks. We repair and replace lead flashings properly - dressed into the brickwork, not cemented over the top. Fixed price, written guarantee.
We respond within hours - 24/7 including weekends and bank holidays.
The chimney is exposed to more weather than any other part of the roof. When homeowners find stains on a ceiling or wall near the chimney breast, the instinct is to check the tiles. Usually it's not the tiles - it's the lead work around the chimney, or the pointing, or the flaunching.
The seal between chimney and roof covering. When it pulls away from the brickwork or cracks, water runs straight down the stack into the building.
Failed mortar joints make the stack porous. Water absorbed by brickwork freezes in winter and accelerates the damage rapidly.
The mortar bed around chimney pots. It cracks and loosens, letting water into the top of the stack - and then straight down inside the chimney breast.
Cracked or uncapped pots on disused chimneys let water directly into the flue. Capping is a simple fix that stops a lot of water ingress.
Lead work is equally as important as the roof covering itself. We don't cement over the top - we dress it into the brickwork correctly.
Individual lead steps cut and dressed into the mortar joints up the side of the chimney stack where it meets a sloped roof. Each step overlaps the tile below. Done correctly, it moves with the building.
The horizontal lead that overlaps the top of step flashings and is chased into the mortar joints of the chimney. Prevents water from tracking behind the step flashings.
The lead valley behind the chimney where the roof meets the back of the stack. One of the most common areas for water ingress if it fails or blocks with debris.
Lead work to bay window roofs and flat-roofed bay extensions. Correctly detailed to prevent water tracking down the front elevation of the property.
Old mortar raked out to 20mm, then repointed with the correct mix. Matched to the existing colour and profile. We use lime mortar for pre-1930s properties.
Flaunching replacement around chimney pots. Capping or removal of disused pots. Full stack rebuilds where deterioration is beyond repair.
"Our roof started leaking with heavy rain. Got their number through a friend, came out next day, completed the repairs in time. Good job. Very courageous team too."
Common signs: damp patches on a wall or ceiling near the chimney breast, a musty smell in the adjacent room, or visible deterioration of the pointing or flashing from the ground. We'll photograph and report everything we find from the roof.
It's done all the time and fails within 2-5 years. Cement doesn't flex with thermal movement the way lead does. We replace the flashing correctly so it lasts - not patch it so it becomes your problem again.
