A well-installed roof is more than just slates and tiles — it’s a system of components working together to keep your property dry and protected. One of the most crucial, but often overlooked, parts is the lead flashing.
What is Lead Flashing?
Lead flashing is a weatherproofing material used to seal joints between your roof and other parts of your building — like chimneys, dormers, or roof valleys. It prevents water from seeping into the gaps where roof surfaces meet walls or other vertical structures.
Why Use Lead?
- Durability: Lead can last for decades, even centuries, when properly installed.
- Flexibility: It expands and contracts with the weather, reducing the risk of cracks and leaks.
- Malleability: It can be shaped to fit any detail or junction in your roof.
Where Do You Find It?
Most commonly, lead flashing is used around:
- Chimney stacks
- Roof valleys
- Skylights and roof windows
- Junctions between roofs and walls
Signs Your Flashing Needs Replacing
- Cracks or splits in the metal
- Lifting or warping from its original position
- Water stains inside the loft or upper rooms
