Chimney and roof junction repaired together
Mortar condition checked
We identify failed joints rather than covering sound and loose areas alike.
Leadwork included
We assess the flashing that seals the base of the chimney.
Nearby covering made good
We check adjoining slate or tiles after the chimney work is complete.
Keep water out around exposed chimney masonry
A chimney stands above the roof and takes the full force of rain, frost and wind. When mortar joints wear away, water can enter the masonry. If the leadwork at its base has lifted or failed, moisture can also pass into the roof space. We assess the mortar, bricks or stone, flashing and nearby slate or tiles before defining the work. This avoids repairing one part while leaving another route open. Confirmed maintenance includes chimney repointing and relaying leadwork, with related roofing repairs considered where the surrounding covering has also been affected.
Remove failed material and make good carefully
Safe roof access comes first. We remove loose or failed mortar where repointing is needed, then apply compatible new material without smearing it across the masonry face. Leadwork can be lifted, correctly relaid or renewed according to its condition and the chimney detail. Where appropriate, we can carry out roofing-related chimney repairs, necessary removal work and making good around the opening. We finish by checking the adjoining roof covering so disturbed slates or tiles don't leave a fresh weakness beside the repaired chimney.
Frequently asked questions
How can failed chimney pointing cause damp?
Open mortar joints allow rain into the masonry, while frost can worsen loose areas. Moisture may then reach the roof space or internal surfaces. Flashing defects can produce similar signs, so we inspect both the stack and its base.
Will chimney repointing include the lead flashing?
We assess both details and provide repointing with leadwork relaying where required. The quote sets out the agreed scope, as sound flashing doesn't need disturbing without reason. Failed material is treated according to its actual condition.
Can unused chimney parts be removed?
Appropriate roofing-related removal work is available, with the surrounding roof made good as part of the agreed scope. We first assess how the chimney connects to the roof and explain the practical work needed to close and weather the area.
