Code-graded lead flashing being dressed around a chimney in Braintree

Leadwork & lead flashing in Braintree

Lead is where most roofs actually leak. Get the flashings right and the rest of the roof looks after itself; get them wrong — or fill the joint with mortar and hope — and you'll be chasing the same damp patch for years.

Leadwork we carry out

Lead detailing on Braintree roofs

Chimney flashings

Front apron, side soakers and stepped cover flashings chased into the mortar joint and wedged, not smeared over the brick. The single most common leadwork job we do.

Abutment and step flashings

Where an extension roof meets the house wall. Done properly in short bays so the lead can move without splitting.

Lead valleys

Traditional lead-lined valleys on period Braintree and Bocking properties, replaced like-for-like at the correct code and bay length.

Dormer and bay roof leadwork

Cheeks, tops and aprons — often the fiddliest lead on a house and the first place a bodged repair shows.

Parapet and gutter linings

Lead-lined box and parapet gutters on older buildings, with proper drips and expansion joints.

Replacing mortar fillets

Cement fillets always crack. We cut them out and replace with code-graded lead — the fix that stops the call-backs.

Doing it right

What proper leadwork looks like

  • Correct lead code for the location and bay size
  • Bays kept short enough for the lead to expand without splitting
  • Chased a minimum of 25mm into the mortar joint and wedged
  • Pointed with a suitable mortar, not silicone
  • Patination oil applied so the lead doesn't stain the brickwork
  • No mortar fillets used in place of lead, anywhere

Local knowledge

Leadwork across the Braintree area

Older housing means more chimneys, more valleys and more lead.

Bocking and CM7 period property

Multiple chimney stacks and lead-lined valleys, frequently with decades of mortar-fillet repairs to cut out first.

Post-war semis

Single stack, simple flashings — a quick job that stops a persistent chimney-breast damp patch.

Extensions and conservatory abutments

Where new work meets old wall. Done in bays, with the correct upstand height rather than the minimum that fits.

Village and listed buildings

Traditional detailing and materials, matched to what's already there and to any conservation requirements.

Common questions

Leadwork FAQs

Why does my chimney flashing keep leaking?
Nine times out of ten it's a cement fillet rather than lead, and cement always cracks as the stack and roof move at different rates. Replacing it with properly chased lead ends the problem.
How long does lead flashing last?
Correctly installed lead flashing regularly lasts 50 years or more — longer than the roof covering around it. Failures are almost always installation faults, not the material.
Can you repair lead rather than replace it?
Sometimes. Lead-welded patch repairs are legitimate on sound lead. Where it's split along a bay because it was laid too long, replacement is the only lasting answer.
Do you use lead on listed buildings?
Yes, and we match traditional detailing. Tell us at survey stage if the property is listed or in a conservation area.
