Why Lead Flashing Is Still the Best Choice for Weatherproofing in Sevenoaks

When it comes to protecting your roof from water damage, very few materials match the strength, durability, and reliability of lead flashing. Even with modern alternatives on the market, lead continues to be the go-to choice for roofers across the UK — and for good reason.

In a mixed-roofing area like Sevenoaks, where homes range from older period properties to newer builds, lead flashing remains one of the most effective ways to seal vulnerable roof junctions and keep your home watertight.

At S Harris Roofing, we install and repair high-quality leadwork throughout Sevenoaks. Here’s why lead flashing is still the top choice for long-lasting roof weatherproofing.

1. Exceptional Durability

Lead is incredibly long-lasting — often outliving the roof itself. Many Sevenoaks homes feature original leadwork that has lasted decades. When installed correctly, lead flashing can withstand wind, heavy rain, UV exposure, and temperature changes without failing.

2. Flexibility and Movement

Sevenoaks experiences a fair amount of seasonal expansion and contraction, which puts pressure on roof materials. Lead naturally moves with the building, preventing splits, cracks, and gaps that can form with rigid materials.

3. Perfect for Older and Traditional Roofs

With many historic and character homes in Sevenoaks, lead flashing blends perfectly with older roof structures. Its timeless look and ability to adapt to uneven surfaces make it ideal for chimneys, valleys, dormers, and roof junctions.

4. Superior Weather Resistance

Lead offers unbeatable protection against water ingress. Whether your home sits in an exposed part of Sevenoaks or a sheltered area, lead flashing provides a strong, reliable barrier against rain, storms, and damp conditions.

5. Long-Term Value for Money

While lead may cost slightly more upfront than some modern alternatives, its lifespan makes it far more cost-effective over time. Homeowners in Sevenoaks often find that well-installed lead flashing won’t need replacing for decades.

6. Environmentally Friendly

Lead is a fully recyclable material with a low environmental impact compared to many synthetic options. Choosing leadwork means choosing a long-lasting, sustainable roofing solution.

Signs Your Lead Flashing Is Failing in Sevenoaks

Signs Your Lead Flashing Is Failing in Sevenoaks

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.

Do I Need My Lead Flashing Replaced or Just Repaired

Do I Need My Lead Flashing Replaced or Just Repaired

Do I Need My Lead Flashing Replaced or Just Repaired?

Lead flashing is one of the most durable and reliable materials used in roofing, but even the toughest materials eventually need attention. If you’re noticing damp patches, leaks around your chimney, or signs of water entering your home, the flashing may be the culprit. The big question for most homeowners is simple — do you need a full replacement, or will a repair do the job?

At S Harris Roofing, we provide professional inspections and expert leadwork repairs across Sevenoaks. Here’s how to tell whether your flashing needs a repair or a complete replacement.

When a Lead Flashing Repair Is Enough

Not every issue requires new leadwork. In many cases, a targeted repair will restore full protection. A repair is usually suitable when:

  • The flashing has minor splits or cracks caused by movement or age
  • The mortar has come loose and the flashing has lifted slightly from the brickwork
  • Only a small section is damaged while the rest is solid
  • There’s early-stage wear but the lead still has thickness and strength

In these situations, we can replace small sections, re-bed the flashing, seal the chase, and reinforce the surrounding area — restoring full weatherproofing without unnecessary cost.

When Lead Flashing Needs Full Replacement

Sometimes a repair just won’t cut it. A full replacement may be needed when:

  • The lead is heavily corroded or paper-thin from decades of exposure
  • The flashing has slipped significantly and can’t be secured properly
  • The original installation was poor and doesn’t meet modern standards
  • Large sections have cracked beyond safe repair
  • Water has penetrated deeply and ongoing leaks are likely

When replacement is required, we install new code-graded lead using traditional, long-lasting methods — ensuring the flashing can withstand the UK climate for decades to come.

How We Assess Your Leadwork

Our process is simple and transparent:

  1. A full visual inspection of the lead flashing and surrounding roof areas
  2. Moisture checks around chimneys, walls, and junction points
  3. A clear recommendation on repair vs replacement — with photos
  4. No-pressure quotes with clear pricing

Most homeowners are surprised how small the issue is once it’s properly assessed. A quick repair now can prevent far more expensive problems later.

Common Lead Flashing Problems in Sevenoaks

Common Lead Flashing Problems in Sevenoaks

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.

Need Reliable Leadwork Repairs in Sevenoaks?

If you’ve noticed staining, leaks, or cracks near your chimney or roof edges, it’s likely your lead flashing is failing. The sooner you get it fixed, the less chance you’ll have of facing costly structural repairs later.
