NFRC memberFully insuredWritten roofing quotationsChimney flashing repairs and roof leadwork
A sound covering can still leak at a poorly performing junction. Chimney flashings, abutments and valleys are all important parts of the roof’s weather resistance. We assess the surrounding construction as well as the visible defect.
Our roof-related chimney and masonry work includes repointing, flaunching, localised brick repairs and flashing repairs or replacement. Share the relevant pages of an existing survey if chimney defects have already been identified.
A leak near the chimney: flashing or masonry?
Flashings weather the junction between the chimney and the roof covering. Mortar joints, the top of the stack and the surrounding tiles or slates are separate parts of the assessment. Damp appearing near a chimney does not identify which detail has failed.
Tell us when the leak happens, which room is affected and what previous repairs were attempted. Repointing addresses masonry joints; repairing or renewing leadwork addresses the metal weathering details. We explain the proposed scope after assessing the relevant areas, including where further specialist investigation may be needed.
What affects chimney flashing repair costs?
The damaged area, condition of the surrounding roof and safe access determine the work and price. A local flashing repair, renewal around a whole stack and chimney masonry repairs involve different scopes. Scaffolding may form a significant part of the quotation.
We identify the proposed work, access and relevant exclusions in a free written quotation. If you already have a building-survey extract, send the relevant findings so we can discuss the assessment needed. Our roofing quotation checklist helps you compare the scope.
Leadwork and weathering
The proposed detail needs to suit the roof and allow the materials to work as intended. We discuss the surrounding covering and connections when assessing repairs or renewal.
- Chimney and wall-abutment flashings
- Lead valleys and gutter details
- Bay and small lead roof coverings
- Weathering around roof junctions
Chimney repairs
Deteriorated mortar, damaged flaunching and local brick defects may need attention alongside the flashings. We distinguish roof-related repairs from work that requires further structural or specialist assessment, and explain the proposed scope.
Make use of planned scaffolding
If a building survey has identified chimney and roof defects, share it before the quotation. Where practical, coordinating related work can help make effective use of access arrangements and reduce repeat disruption.

Chimney and lead flashing repair questions
If you have a specific concern about your roof, tell us when you enquire.
How much does chimney flashing repair cost?
The damaged leadwork, surrounding roof condition, chimney position and safe access determine the scope and price. A local repair and complete renewal around a stack involve different work. We discuss the assessment needed and provide a free written quotation before you decide.
Will repointing alone stop a chimney leak?
Only if the problem is confined to the masonry joints being repaired. Flashings, adjoining coverings and other chimney details may also need attention. We assess the relevant areas and explain the proposed work rather than treating every chimney leak as a pointing problem.
Can damaged lead flashing be repaired rather than replaced?
That depends on the condition of the lead and the surrounding detail. A local repair may be appropriate in some cases; wider defects or a poor existing arrangement may need renewal. We explain the suitable options after assessment.
Can you review the chimney section of a building survey?
Yes. Email the relevant sections and tell us the property postcode. We can discuss the identified roof-related chimney and masonry work and any inspection needed before quoting.
Do chimney repairs require scaffolding?
Safe access depends on the height, position and proposed work. We assess what is needed for the property rather than assuming the same arrangement for every chimney.
Can the chimney work be done during a roof replacement?
Often it can be considered within the same programme. Share known defects at the outset so the scope and access can be planned together.
