Sealing the junctions the roof covering can't
Tiles and slate are designed to shed water on open slopes, but at junctions — chimneys, walls, valleys — they rely entirely on lead flashing to stay sealed.
Flexibility that rigid materials can't match
Lead can be dressed and shaped to fit complex junctions in a way that rigid roofing materials can't, making it the standard solution for detailing work.
Genuine durability
Properly installed lead flashing can last many decades, often outlasting several generations of the roof covering around it.
Why it's worth getting right
Because leadwork covers the highest-risk junctions on a roof, a failure here causes disproportionate damage compared to its size — a small area of failed flashing can lead to a significant leak.
If you're dealing with a leak near a chimney or valley, our leadwork team can assess whether flashing is the cause.
