Lead Flashing Repairs in Halifax, Calderdale

You might be wondering why lead is still the 'go-to' material in a world of modern plastics. It is simple: nothing handles the expansion and contraction of the British weather quite like it. Properly installed lead can last for over a hundred years, but only if it is fitted correctly. We see a lot of 'botch jobs' where lead has been held down with mastic or silicone, which eventually cracks and peels away. We do things properly, following BS 6915 standards. This means we use the right 'Code' of lead for the job—usually Code 4 or 5 for things like valleys and flashings—to ensure it is thick enough to withstand the elements without being so heavy it causes structural strain. If you have noticed damp patches appearing on the chimney breast, it is a clear sign your leadwork needs a professional eye.

Chimneys are one of the most common spots for leaks because they are exposed to the wind from every angle. We specialise in step flashings, where we cut 'steps' into the masonry of your chimney and tuck the lead deep into the mortar joints—a process known as chasing. We then point it back up securely so water cannot be 'sucked' upwards by capillary action. For areas where the roof meets a flat wall, we install apron flashings and soakers. If your home has a roof valley—that 'V' shape where two roof slopes meet—we can reline it with high-quality lead to ensure the water flows straight into your gutters rather than into your rafters. It is all about creating a seamless, watertight barrier that protects the timber skeleton of your home from rot.

Have you ever seen a new roof with ugly white streaks running down the tiles? That is caused by lead carbonate forming when new lead meets rainwater. It looks messy and can actually degrade the lead over time. To prevent this, our team always applies patination oil as soon as the lead is installed. This gives it that classic, dull grey finish from day one and protects the surface from the weather. It is a small step, but it is one that many cut-price roofers skip. We also offer lead welding, also known as lead burning. This involves using high heat to fuse sheets together, creating a much stronger and more flexible bond than traditional soldering. This is essential for complex shapes or large flat sections where you need a permanent, leak-proof seal.
