Why Leadwork Matters

Lead flashing is one of the most durable and flexible waterproofing solutions for critical roof junctions. Properly installed lead:

  • Expands and contracts without cracking

  • Offers long-term resistance to corrosion and weathering

  • Provides superior sealing around chimneys, dormers, valleys and parapets

  • Maintains integrity in harsh UK weather conditions

When leadwork fails or is compromised, leaks, damp patches, or structural damage can occur. That’s why expert installation and maintenance are essential.

    Leadwork and Flashing FAQs

    Q1: How long does lead flashing last?
    A1: High-quality lead flashing installed correctly can last 50+ years, if maintained and not exposed to mechanical stress.

    Q2: Can you repair a flashing leak without replacing the whole piece?
    A2: Yes — minor leaks can often be patched, joints re-soldered or sealants replaced. But major corrosion or fatigue may require full replacement.

    Q3: Does leadwork suit modern or heritage homes?
    A3: Absolutely. Lead flashing is ideal for both—modern detail and period restoration alike.

    Q4: What lead thickness is suitable?
    A4: For most domestic flashing work we use Code 4 lead (3 mm) or Code 5/6 depending on design, exposure, and structural needs.

    Q5: Do you offer emergency flashing repair?
    A5: Yes — we provide emergency callouts to stop leaks quickly and stop further water damage until full repairs are made.
