Signs Your Lead Flashing Is Failing in Sevenoaks
Lead flashing plays a crucial role in keeping your roof watertight, especially around chimneys, roof junctions, and walls. In a town like Sevenoaks, where many homes feature older roofs and traditional construction, worn or damaged flashing is one of the most common causes of leaks.
Spotting the early signs of failing leadwork can save you thousands in repair costs. At S Harris Roofing, we carry out expert lead flashing repairs throughout Sevenoaks and the surrounding areas. Here’s what to look out for.
1. Damp Patches Inside Your Home
If you’re noticing damp marks on ceilings or walls — especially near your chimney breast — it’s often a sign that the lead flashing has pulled away or cracked. Sevenoaks properties with older brickwork are particularly prone to this issue.
2. Water Stains Around the Chimney
Watermarks around the chimney area usually indicate that water is getting past the flashing. Homes in Sevenoaks often experience this after heavy rain or strong winds.
3. Visible Cracks or Splits in the Lead
Over time, lead naturally expands and contracts. This movement can create cracks. If you live in an exposed part of Sevenoaks, such as higher ground or open areas, temperature changes can accelerate this wear.
4. Flashing That Has Lifted From the Brickwork
If the mortar has deteriorated, the flashing can slip or lift away from the brickwork. This creates a direct pathway for water to enter. Many older Sevenoaks roofs show this exact problem due to ageing mortar lines.
5. Moss or Algae Buildup Around Junctions
Moss doesn’t just look unsightly — it holds moisture against the leadwork, which speeds up deterioration. Several homes we inspect in Sevenoaks show moss buildup where flashing has already begun to fail.
6. Corrosion or Thinning Lead
Although lead typically lasts decades, older Sevenoaks roofs can suffer from corrosion or thinning after long-term exposure. Once the material becomes too thin, replacement is usually required.
Why Sevenoaks Homes Experience Leadwork Issues
Many properties in Sevenoaks are exposed to heavy rainfall, older brickwork, and varying roof styles. This combination means flashing naturally takes a beating over the years. Regular inspections can prevent small issues from becoming costly structural problems.
