Common Lead Flashing Problems in Sevenoaks Homes
Lead flashing is one of the most important barriers protecting your home from water ingress, especially around chimneys, roof junctions, and walls. In a historic area like Sevenoaks, where many properties feature older roofing systems, leadwork issues can appear without warning. Left untreated, even a small gap or crack in your flashing can quickly develop into a serious leak.
At S Harris Roofing, we specialise in professional leadwork repairs across Sevenoaks, helping homeowners keep their roofs watertight, secure, and built to last. Here are the most common problems we see and how we fix them.
1. Cracked or Split Lead Flashing
Over time, exposure to the elements causes lead to expand and contract. This natural movement can lead to cracks and splits, especially on older roofs. Once the flashing fails, water begins to seep into vulnerable areas of the roof.
Our fix: We replace damaged sections with new code-graded lead and secure it correctly to prevent future movement issues.
2. Lead Flashing Pulling Away from the Brickwork
If your lead flashing wasn’t installed correctly or has been affected by strong winds, it can pull away from the mortar joints. This leaves gaps where water can flow directly into the property.
Our fix: We re-bed the flashing properly, add new fixings, and seal the chase with high-quality mortar for long-lasting protection.
3. Corroded or Weathered Lead
Although lead is extremely durable, decades of exposure can eventually cause corrosion or surface wear. Weathered lead becomes thinner and far less effective at diverting water.
Our fix: We replace severely worn leadwork and treat the surrounding roof area to improve longevity.
4. Poorly Installed Flashings
We often come across flashing that has been installed incorrectly by previous contractors or during rushed repairs. If the lead is too thin, not chased into the brickwork, or laid incorrectly, leaks are inevitable.
Our fix: We remove faulty flashing and install new code-appropriate lead using industry-standard techniques.
5. Blocked Gutters Causing Water Overflow
When gutters become blocked, water can overflow and put pressure on the leadwork around roof junctions. Over time, this weakens the flashing and leads to internal damp patches.
Our fix: We clear the guttering, assess the damage, and repair or reinforce the leadwork accordingly.
