Expert Lead Work and Flashing — The Key to a Watertight Roof
Lead has been used in roofing for centuries, and it remains the gold standard material for creating watertight seals at the most vulnerable points of your roof. Wherever your roof meets a wall, chimney stack, skylight, dormer window, or another roof section, lead flashing provides the critical weatherproof junction that prevents water from penetrating the structure. When lead work fails — due to age, corrosion, thermal movement, poor original installation, or physical damage — the result is almost always a leak. These leaks can be persistent and difficult to trace, as water can travel along timbers and rafters before appearing as a damp patch on a ceiling or wall some distance from the actual point of entry. Thermoshield Ltd has over 20 years of experience diagnosing and repairing lead work failures across Hampshire, Surrey, and Berkshire, and we understand how to trace these problems back to their source and fix them properly.
We carry out all types of lead work and flashing repairs and replacements — from chimney flashings and step flashings to lead valleys, apron flashings, back gutters, and skylight surrounds. Whether you need a cracked chimney flashing re-sealed on a terraced house in Farnborough, a full lead valley replacement on a detached property in Ascot, or new lead work around a dormer window in Fleet, our skilled team delivers precise, durable results using code-appropriate lead sheet and traditional dressing techniques. We never use quick-fix sealants or flashing tape as a permanent solution — only properly installed lead that will protect your home for decades.

Frequently Asked Questions About Lead Work & Flashing
Lead work and flashing can seem technical, but the problems it causes are straightforward — leaks. Here are the answers to the most common questions homeowners across Hampshire, Surrey, and Berkshire ask about lead work. Call 07505 262511 if you need further advice.
Lead flashing is a strip of lead sheet used to create a watertight seal wherever your roof meets a wall, chimney, skylight, or another roof section. These junctions are the most vulnerable points on any roof, and without properly fitted flashing, rainwater would penetrate the join and cause damp, rot, and interior damage. Lead is the preferred material because it is extremely durable, malleable, and resistant to corrosion.
Common signs include damp patches or water stains on ceilings and walls near chimneys, skylights, or where an extension meets the main house. You may also notice gaps where lead has lifted away from the brickwork, visible cracks in the lead itself, or daylight showing through flashings when viewed from inside the loft. If you spot any of these signs, it’s worth getting a professional inspection before the damage spreads.
Properly installed lead flashing using the correct code of lead typically lasts 50 to 100 years or more. However, lead that was poorly installed, too thin for the application, or subjected to excessive thermal movement may fail much sooner. We always use the appropriate code of lead for each application to ensure maximum longevity.
It depends on the extent of the damage. Small cracks or localised failures can often be repaired effectively, but if the lead is extensively corroded, has thinned over a large area, or was poorly installed to begin with, a full replacement is usually the better long-term investment. We’ll always give you an honest assessment and explain both options during your free inspection.
Flashing tape and sealant products can provide a temporary fix in an emergency, but they are not a long-term substitute for properly installed lead. Self-adhesive tapes degrade in UV light, lose adhesion over time, and rarely last more than a few years. We always recommend proper lead flashing for any permanent repair, as it is significantly more durable and reliable.
The cost depends on the type and size of the flashing, the accessibility of the roof, and whether a repair or full replacement is needed. A simple re-seal on a small chimney flashing will cost considerably less than a full valley lining replacement. We provide free, no-obligation quotes for all lead work.
