What this service involves
Lead flashings and roof junctions
Lead flashing helps protect vulnerable junctions between sloping roof coverings and walls or chimneys. Poorly fitted, loose or damaged flashing may contribute to leaks. We assess what needs repairing or renewing.
Party walls and abutment details
Where roofs meet a party or fire wall, the correct junction treatment is important. The roof covering, wall finish and lead dressing all need to be considered together.
Distinguishing chimney leaks from nearby roof defects
A damp patch beside a chimney does not always mean the chimney itself is at fault. Defective tiles, underlay, roof valleys or flashings nearby can also cause water ingress. We investigate before advising on work.
Frequently asked questions
Can you repair lead flashing around a chimney?
Yes. We carry out leadwork and flashing repairs around chimneys and roof junctions.
Do you repoint chimney stacks?
Yes. Chimney repointing and associated roof repairs are among our services.
Do you work on party-wall roof junctions?
Yes. We can assess roof-to-wall junctions, flashing and lead dressing requirements.
Chimney repointing and lead flashing repairs
Chimney stacks and party-wall junctions interrupt the roof covering, so correct flashing and sound masonry are important. Cracked pointing, loose mortar, weathered lead or a poorly detailed stepped flashing can allow water to move behind tiles or slates. Finding the actual entry point helps avoid unnecessary work on otherwise sound roofing.
Leadwork at chimneys, valleys and adjoining walls
Where roofs meet brickwork, lead should be suitably dressed and secured for the roof design. Valleys and abutments also need water to discharge without backing up beneath coverings. We can discuss chimney cement and repointing work, lead flashing renewal and repairs around fire or party walls, subject to inspecting the existing structure.
Could a chimney leak look like a general roof leak?
Yes. Water may track down from a flashing or masonry joint before appearing indoors. We assess the likely source and can coordinate related tile and slate repairs, or discuss roof replacement where justified.
Chimney and roof junctions that deserve attention
A chimney or party-wall junction contains several weather-exposed details working together. Cracked pointing, loose render, mortar joints and lead flashings can contribute to water entry; a failed slate nearby can create an almost identical interior stain. A reliable inspection should distinguish between them.
- Check chimney pointing, bedding and mortar condition.
- Review lead flashings, steps, soakers and abutment joints where present.
- Examine party-wall and fire-wall lead dressing at roof intersections.
- Look at valleys, gutters and adjacent roof coverings for diverted water.
- Identify cracks or movement affecting the masonry or surrounding detail.
- Review how water discharges off the flashing and over the roof covering.
- Assess whether local repairs or more extensive renewal are warranted.
Questions about lead flashing and repointing
Can lead be repaired instead of completely replaced? That depends on its condition, the type of failure and the available working length. We would need to examine the detail before recommending a solution.
Will fresh pointing cure every chimney leak? No. Lead flashings, chimney pots, masonry and the adjacent tile or slate covering may all need assessment.
What if another roofer guaranteed the roof? It is sensible to contact the existing guarantee provider first when applicable. We can discuss any separate inspection or repair work needed.
