Urgent Lead Flashing Repointing Needed in Catford London with 10 Year Warranty

Urgent Lead Flashing Repointing in Catford, London

I need an urgent quote in writing for the following: re-pointing the lead flashing where the lower roof adjoins the main building and where the chimney stack is situated. Needs to be backed with a 10-year warranty. This is very time sensitive, the repair needs doing within the next two weeks.

Understanding Lead Flashing Repointing and Why It’s Necessary

Lead flashing plays a crucial role in preventing water ingress where two surfaces meet, such as a lower roof abutting the main structure or around a chimney stack. Over time, weathering, temperature fluctuations, and general wear can cause the mortar securing the flashing to deteriorate, leading to potential leaks and structural damage.

Common Issues with Lead Flashing in Catford, London

In areas like Catford (SE6), homes often feature traditional pitched roofs with lead flashing installed along roof junctions and chimneys. Due to the variable London climate—frequent rain, occasional frost, and seasonal expansion/contraction—flashing mortar can crack or loosen, necessitating repointing.

Steps Involved in Repointing Lead Flashing

Repointing lead flashing is a precise process that requires expert handling. Here’s what the job typically involves:

  1. Inspection and Assessment: A roofing professional will first inspect the existing flashing and surrounding masonry to assess the extent of deterioration.
  2. Removal of Loose or Damaged Mortar: Any cracked or loose mortar around the lead flashing is carefully removed to create a clean surface for repointing.
  3. Repointing with Weather-Resistant Mortar: A high-quality, lead-compatible mortar (often a lime-based or specialist lead sealant) is applied to secure the flashing firmly.
  4. Sealing and Finishing: The repointed area is smoothed and sealed to ensure long-term protection against water ingress.
  5. Final Inspection and Cleanup: Once cured, the work is inspected for quality, and any debris is removed from the site.

Estimated Costs for Lead Flashing Repointing

Repointing lead flashing costs depend on the extent of the repair, accessibility, and materials used. In Catford, London, typical costs range from:

  • Small Section (1-2 metres): £150 – £300
  • Chimney Flashing Repointing: £250 – £500
  • Extensive Flashing Repointing (Full Roof): £500 – £1000

A 10-year warranty is a reasonable expectation for a well-done repointing job, provided the work is carried out with quality materials and proper adhesion techniques.

Materials Required

  • Weather-resistant mortar or lead-compatible sealant
  • Pointing trowel and jointer
  • Wire brush and chisel for old mortar removal
  • Sealant gun (if using lead-compatible sealant)

How Long Will the Job Take?

Most lead flashing repointing jobs take between half a day to two days, depending on the extent of the damage and accessibility of the work area. Given the urgency, it’s advisable to book a roofer as soon as possible to meet the two-week deadline.

Regulatory Considerations and Planning Permission

For lead flashing repairs, planning permission is generally not required unless the building is listed or in a conservation area. It’s worth checking with Lewisham Council if your property falls under special regulations.

Where to Source Materials Locally

If you need to procure materials yourself or confirm what will be used, local suppliers in and around Catford include:

  • Travis Perkins – Lewisham (for lead-compatible mortars and roofing tools)
  • Selco Builders Warehouse – Catford (roofing supplies and sealants)
  • Jewson – Sydenham (general roofing materials and trade advice)

Preparing for the Work

Since repointing is a relatively non-invasive job, disruption to daily activities should be minimal. However, homeowners can take the following steps:

  • Ensure clear access to the roof for scaffolding or ladders.
  • Remove outdoor furniture or valuables near the work area.
  • Communicate any specific time constraints with the roofer.
