Leadwork is a bespoke trade that has been around for centuries, dating back to antiquity. Lead flashing is one of the most common types of leadwork used in construction and building maintenance. Lead flashing is a strip of lead metal used to seal joints between two different materials. Lead flashing prevents water from entering the joint, which can cause damage to the structure or material if left unchecked.
The lead must be installed correctly by a qualified company due to its malleability, meaning it needs regular checking and maintenance to ensure it’s doing its job perfectly. The longevity and durability of lead make it an ideal choice for many applications, but only when expertly applied by a professional craftsman, such as our team here at Leicester Roofing Services.
Lead flashing is available in various thicknesses, allowing it to be used for different purposes, such as forming weathering details or gutter linings. Lead flashing can also be coloured or patterned to help blend into the existing architecture. The British standard for lead as a material is BS EN 12588. This standard relates to its thickness consistency and the formation of a knitted grain
What is Leadwork on a roof?
Leadwork on a roof involves installing lead sheeting or lead flashing to waterproof and protect the top. Lead sheeting can be used on flat roofs and pitched roofs, providing an effective barrier against water and weather damage. Leadwork is also aesthetically pleasing, making it popular for historic buildings or homes looking for a traditional style. Lead work is carried out by experienced tradespeople who use specialist tools and techniques to ensure a professional finish. Lead expands and contracts during different weather conditions and temperatures, so detailing must be allowed to prevent stresses from forming in the lead sheet.
Leadwork can help extend your roof’s life, saving you money in the long term as repairs are less likely to be needed. Leadwork has many advantages over other roof coverings. If you want protection from the elements, consider investing in this versatile material.

Do Roofers still use lead ?
Lead flashing is still used on roofs. However, it is being slowly replaced by more modern materials such as aluminium and plastic. Lead flashing is a traditional material used for hundreds of years and is still commonly used in heritage properties or listed buildings where the style needs to remain the same. Lead flashing can be extremely durable if installed correctly, but due to its toxicity, it should only be handled by experienced roofers trained to do so safely. Lead is also susceptible to corrosion, so it must be regularly inspected and maintained over time. Ultimately, while lead flashing is still an option for some projects, modern materials such as aluminum or plastic have primarily taken their place due to their durability to withstand harsh weather conditions better than lead. Lead flashing is still preferred and recommended for large residential, commercial, or industrial buildings and churches.
What is the life expectancy lead flashing?
Lead flashing is one of the oldest and most durable forms of waterproofing, with a long lifespan. Lead flashing typically lasts between 25 and 50 years, depending on how it is cared for and maintained. In some cases, the flashing has a life expectancy of 100 years if fitted correctly and allowed to expand and contract freely.
Lead can withstand extreme weather conditions such as heavy snow, hail, rain, high winds, and even UV radiation from sunlight. Lead should be inspected regularly to check for any signs of damage or wear to ensure proper functioning over time. Proper maintenance is essential to maximize the life expectancy of lead flashing. If left unchecked, lead can eventually corrode and fail, which could lead to water leakage issues in your building. Regular inspection and maintenance are imperative when preserving the longevity of lead flashing so it can protect your building from the elements for years to come. Lead flashing is a reliable and cost-effective waterproofing option that will last you for many years with proper care. Investing in quality lead flashing could save money, time, and headaches. Lead flashing is an excellent choice for the long-term protection of your building. Contact a professional if you have questions about the installation or maintenance of lead flashing.
