Roofing

Chimneys, Leadwork & Flashing

Chimney repairs, lead flashings, valleys and the junctions where roofs leak most.

Where a roof meets a chimney, a wall or another roof, something has to keep the water out of the joint. On most older houses that something is lead, and when it splits, lifts or its pointing falls out, the leak shows up on the chimney breast or the ceiling beside it.

What this work covers

Chimney flashings

Renewing the lead soakers, step flashings and back gutter around a chimney stack, and repointing the joint where the lead is tucked into the brickwork.

Chimney stacks

Repointing, rebuilding loose brickwork at the top of the stack, refixing or replacing pots, and capping a chimney that is no longer used.

Valleys and abutments

Lead valleys between two roof slopes and flashings where a roof meets a wall, including on extensions.

How we approach it

  1. Find the failure: a split in the lead, a lifted flashing, failed pointing or porous brickwork can all look like the same damp patch.
  2. Access: chimney work usually needs scaffolding or a chimney platform, which we include in the quote.
  3. Neighbours: if new flashing has to be cut into a neighbour's wall, the Party Wall etc. Act 1996 can apply and notice may be needed. We will flag it early.

Common questions

Problems we are asked about

Before you ring

Questions we get asked about chimneys, leadwork & flashing

Why is my chimney breast damp?

Water can be getting in through the flashing, the brickwork, the top of the stack or an uncapped pot, and each needs a different repair. We look at all of them before quoting.

Do I need my neighbour's permission for chimney work?

If the work touches a shared chimney or cuts into their wall to insert a flashing, the Party Wall etc. Act 1996 may apply and you may need to give notice.
