Lead roofing repairs involve restoring cracked, split, or displaced lead sheets and flashings to stop leaks and extend the roof’s lifespan. When repaired correctly by a specialist, a lead roof can last more than 60 years, making it one of the most durable and sustainable roofing options available.

At Premier Roofing & Construction, we carry out professional lead roof repairs across London, Essex and Kent, combining traditional craft with modern safety and compliance standards.

Why Lead Roofing Needs Specialist Repairs

Lead is incredibly durable, but over decades of expansion and contraction it can fatigue, crack, or lift from its fixings. Once joints fail, water quickly finds its way underneath, causing leaks and corrosion. Because lead is a soft metal, repairs must be handled by trained installers who understand correct detailing, codes of lead sheet and the guidance of the Lead Sheet Association (LSA). Poor workmanship can cause more harm than the original problem.

Common Lead Roof Problems

Even the best-installed lead roof will eventually need attention. The most frequent issues include cracking caused by temperature changes, corrosion from trapped moisture, and leaks where joints or laps have opened. Loose flashings and poor historic detailing are also common, and in some areas theft or partial loss of lead sheets remains a concern. Spotting these problems early prevents water damage to the structure beneath.

How Lead Roofing Repairs Are Carried Out

Every repair begins with a full roof survey to assess whether existing leadwork can be salvaged or replaced. At Premier Roofing & Construction, our specialists follow a clear process: we inspect for fatigue and splits, determine the correct code of lead sheet, and decide whether sections should be welded, re-dressed or renewed entirely. Damaged areas are cleaned, joints resealed and fixings re-secured to restore full waterproofing. Where necessary, ventilation is improved to reduce the risk of future cracking. Each repair is completed to LSA standards, ensuring long-term performance and a clean, professional finish.

How Much Do Lead Roof Repairs Cost?

Lead repair costs depend on access, roof size and detailing. As a guide, minor flashing reseals or small crack repairs typically cost £300–£700, while partial re-laying or larger replacements usually start around £800–£1,200. Complex heritage detailing or multi-level roofs can cost more. For accurate pricing, arrange a roof survey so we can inspect the condition and provide a detailed report. Book a roof survey here.

Maintaining a Lead Roof

Preventative maintenance dramatically extends a lead roof’s lifespan. Keeping gutters and outlets clear of debris, checking flashings after heavy weather, and avoiding foot traffic on the surface all help preserve its condition. We also recommend professional inspections every two to three years, especially on older roofs. Routine checks can catch small splits before they develop into leaks or structural damage.
