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

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

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.

Professional Lead Flashing Installations in Sevenoaks

If you want a durable, weatherproof solution for your roof, lead flashing is still the best material available. Whether you need repairs or a full replacement, our team at S Harris Roofing provides expert leadwork services across Sevenoaks.

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.

Need Expert Lead Flashing Repairs in Sevenoaks?

If you’re noticing any of the signs above, it’s best to get your leadwork checked sooner rather than later. A quick repair today can prevent serious damage in the future.

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.

Need Lead Flashing Repairs in Sevenoaks?

If you’re unsure whether your lead flashing needs a repair or full replacement, we’re here to help. We offer fast inspections, honest advice, and high-quality workmanship on every job.

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.

Chimney Removal in Dartford – Safe, Professional, and Fully Guaranteed

Got a chimney that’s cracked, unused, or leaking beyond repair? S Harris Roofing provides safe and professional chimney removal services across Dartford. Whether you need a full-stack removal or just the section above the roofline gone, we’ll handle everything from scaffolding to sealing your roof – neatly and safely.

Why Consider Chimney Removal?

Not all chimneys are worth repairing. If your flue is redundant, unsafe, or causing persistent leaks, removal can be the most cost-effective long-term option. We carry out full or partial chimney removals, ensuring your roof remains weatherproof and structurally sound.

  • Leaking or cracked stack: Beyond economical repair? Removal may be best.
  • Unused flues: No longer needed after heating system upgrades.
  • Roofline leaks: Persistent flashing or mortar failures.
  • Modernisation: Streamline your roof and improve aesthetics.

Types of Chimney Removals We Offer

  • Partial removal: Taking down the stack to below roof level and sealing over the opening – ideal for inactive flues.
  • Full removal: Complete stack and breast removal through loft or entire property (in coordination with builders).
  • Stack reduction: Lowering unsafe or leaning chimneys for safety while retaining part of the structure.

How Much Does Chimney Removal Cost in Dartford?

Prices vary depending on height, access, and how much of the structure is being removed. Typical Dartford pricing guide:

Chimney Removal Type Typical Cost Details
Partial chimney removal (above roofline) £1,200 – £1,800 Includes removal, re-roofing, and weatherproof sealing
Full external stack removal £1,800 – £2,800 Includes scaffold, brick removal, and leadwork reinstatement
Full internal & external chimney removal £2,500 – £4,500+ Done in coordination with building team and structural supports

Free inspection available: Request a quote and we’ll assess your chimney’s condition, access, and best removal option.

Chimney Removal FAQs

Do I need planning permission to remove a chimney?

Usually not for partial removals above the roofline, but full removals may require building regulation approval. We’ll guide you through it.

Can you remove just the top part of my chimney?

Yes, partial removals are common and cost-effective for redundant flues that still support internal walls.

Will removing a chimney cause leaks?

No — we fully re-tile, felt, and seal the roof to make sure it’s watertight and neat.

What happens to the debris?

All bricks and rubble are cleared from site responsibly and recycled where possible.

Can you remove a shared chimney between two houses?

Yes, but it must be done carefully and agreed with the neighbour. We handle party-wall arrangements if needed.

How long does chimney removal take?

Typically 1–2 days for a small stack, up to a week for full internal and external removal jobs.

Will chimney removal lower my insurance premiums?

It can — insurers often see it as a reduced fire and leak risk, but you should check with your provider.

Chimney Cowl & Cap Installation in Dartford

Chimney Cowl & Cap Installation in Dartford

Chimney Cowl & Cap Installation in Dartford – Protect Your Chimney from Rain and Pests

If your chimney is letting in rainwater, draughts, or nesting birds, it’s time to fit a proper cowl or cap. S Harris Roofing supplies and installs quality chimney cowls and caps across Dartford to stop leaks, improve safety, and extend the life of your chimney stack.

Why Fit a Chimney Cowl or Cap?

A chimney cowl or cap sits at the top of your chimney pot to keep out rain, birds, and debris while allowing proper ventilation. Without one, you’re exposed to water ingress, downdraughts, and blockages that can cause smoke blowback or damp issues indoors.

  • Prevents rain and moisture entering your flue
  • Stops birds, squirrels, and debris from nesting
  • Improves ventilation and prevents smoke blowback
  • Reduces heating loss from open flues
  • Helps prolong chimney lifespan

Types of Chimney Cowls & Caps We Fit

  • Rain cowls: Prevent rain entry and downdraughts while maintaining airflow.
  • Bird guards: Stop birds and small animals from nesting inside the flue.
  • Anti-downdraught cowls: Ideal for windy or exposed properties in Dartford.
  • Solid caps: Seal off unused chimneys to prevent heat loss and moisture.
  • Custom stainless steel cowls: Durable, long-life options for coastal or high-exposure homes.

How Much Does Chimney Cowl Installation Cost in Dartford?

Prices depend on the number of pots, access height, and cowl type. Here’s a quick guide:

Service Typical Cost Notes
Standard rain cowl supply & fit £120 – £180 Galvanised or aluminium cowl installed securely
Stainless steel anti-downdraught cowl £180 – £260 Ideal for windy areas or coastal exposure
Solid cap for unused flue £100 – £160 Includes vent holes for moisture control
Multiple pot installation (2–4 pots) £200 – £400 Includes safety access and fitting per pot

Free quotes available: Book your survey for a fixed written price with photos of the finished work.

Our Chimney Cowl Fitting Process

  1. Inspection: Check pot condition and ensure correct cowl type for your flue.
  2. Recommendation: Advise on the best model for ventilation and weather exposure.
  3. Safe fitting: Secure ladder or scaffold access for safe installation.
  4. Installation: Fit cowl or cap using stainless steel fixings or strap banding.
  5. Final check: Test for stability and airflow, take before/after photos.

If your chimney also needs repointing or flashing repairs, we can carry out all works in one visit for cost efficiency.

Why Choose S Harris Roofing in Dartford

  • Experienced installers: Hundreds of cowls fitted on homes across Dartford and Kent.
  • Quality materials: Stainless steel and weather-resistant designs only — no cheap imports.
  • Fully insured: Work at height carried out safely and responsibly.
  • Fair prices: Up-front written quotes, no hidden extras.
  • Guaranteed work: Every installation comes with a workmanship guarantee.

Chimney Cowl & Cap FAQs

Can a cowl stop rain from getting in?

Yes. A properly fitted rain cowl stops most water ingress while still allowing your chimney to breathe.

Do you fit cowls on tall or difficult-to-access chimneys?

Yes. We have the equipment and experience to work safely on all property types, including tall or steep roofs.

Will a cowl stop birds from nesting?

Absolutely. Bird-guard cowls are designed specifically to keep out pigeons, jackdaws, and other nuisance birds.

How long do chimney cowls last?

Galvanised models typically last 8–10 years; stainless steel versions can exceed 20 years with no maintenance.

Do I need planning permission?

No — chimney cowls and caps are classed as minor alterations. We just ensure they comply with ventilation and flue type requirements.

Can you remove or replace old cowls?

Yes. We safely remove old rusted or damaged cowls and replace them with modern, secure versions.

What’s the best type of cowl for solid-fuel fires?

Anti-downdraught or rotating cowls work best, as they improve draw and prevent smoke blowback in windy conditions.

Common Lead Flashing Problems in Sevenoaks

Chimney Lead Flashing Repairs in Dartford

Chimney Lead Flashing Repairs in Dartford – Stop Roof Leaks at the Source

Noticing water marks near your chimney breast or in the loft? Nine times out of ten, it’s failed lead flashing. S Harris Roofing provides professional chimney lead flashing repairs across Dartford to seal out the weather and protect your home.

What Is Lead Flashing & Why It Fails

Lead flashing is the protective sheet that bridges the gap where your chimney meets the roof. Over time, flashing can split, lift, or pull away if it was poorly detailed, fixed with the wrong sealant, or stressed by movement and weather.

  • Common failures: split lead, loose step flashing, missing soakers, dried/cracked mortar chases, failed sealants.
  • Typical symptoms: damp patches on ceilings/walls, musty loft insulation, staining around the chimney breast.

Chimney Lead Flashing Repair Costs in Dartford

Exact pricing depends on access, stack height, and the extent of damage. Here are straightforward ballparks:

Lead Flashing Task Typical Price Range Notes
Re-seal mortar chase & minor re-dress £180 – £350 For small lifts/splits with good base lead
Replace apron or step flashing (single face) £300 – £550 Includes cutting chases and fixing correctly
Full chimney re-flash (apron, steps & soakers) £650 – £1,100 Best for recurring leaks / worn-out lead
Re-flash + repointing to chimney faces £800 – £1,400 Bundle to solve both causes of ingress

Next step: Book a free inspection and fixed quote. Request a visit and we’ll confirm the exact price after a safe survey.

How We Repair Chimney Lead Flashing (Properly)

  1. Survey & photos: Identify split/loose lead, check soakers and mortar chases.
  2. Preparation: Lift tiles as required, remove failed sealants, rake out chases cleanly.
  3. New leadwork: Fit correctly sized code 4/5 lead (as appropriate), with stepped flashing and individual soakers.
  4. Fixing & sealing: Secure with appropriate fixings and chase seal (lead-compatible), then neatly dress for water runoff.
  5. Finishing: Re-bed tiles, tidy the work area, provide before/after photos.

If the brick joints are also failing, we’ll recommend repointing to stop the problem returning.

Why Choose S Harris Roofing in Dartford

  • Leadwork specialists: Proper step flashing, soakers and apron detailing — no shortcuts.
  • Local & reliable: We know Dartford’s property styles and typical weak points.
  • Transparent pricing: Clear written quotes, no hidden extras.
  • Quality materials: Correct lead codes and compatible sealants for long-term performance.
  • Guaranteed repairs: Workmanship backed by our guarantee and photo evidence.

Lead Flashing Repair FAQs

Can you repair flashing without scaffolding?

For low, accessible stacks, yes — we can often work safely from ladders/towers. Taller stacks or complex roofs may require scaffold for a proper job.

Do you use lead or alternatives?

We primarily use lead due to its longevity and malleability. Where specified, we can fit lead-alternative systems — we’ll advise what’s best for your roof.

Will new flashing stop my leak completely?

If flashing is the cause, yes. If mortar joints or chimney caps are also failing, we’ll address those in the same visit to guarantee a watertight result.

How long does a re-flash take?

Minor re-dress/re-seal: a few hours. Full re-flash with soakers: typically 1 day, depending on access and weather.

What lead code should be used?

Usually code 4 or 5 depending on span and exposure. We follow best practice so your flashing lasts.

Do you provide photos and a guarantee?

Yes — you’ll get before/after photos and a written guarantee on our workmanship.

Chimney Repointing in Dartford

Chimney Re-pointing in Dartford

Chimney Repointing in Dartford – Stop Leaks Before They Worsen

If your chimney mortar is cracking or crumbling, it’s time to act. Weather and age can wear down the joints that hold your chimney together, letting water in and weakening the structure. S Harris Roofing offers professional chimney repointing in Dartford to restore strength, prevent leaks, and extend the life of your roofline.

Why Chimney Repointing Matters

Mortar joints protect the brickwork from water penetration. When they fail, moisture seeps in, leading to internal damp, frost damage, and even chimney instability. Repointing replaces the old, damaged mortar with fresh, properly mixed material to keep your chimney weatherproof and structurally sound.

How Much Does Chimney Repointing Cost in Dartford?

Most chimney repointing jobs in Dartford fall between £350 and £1,100, depending on size, height, and condition. Small patch repairs are cheaper, while full four-face repointing on a tall stack can reach the upper end of that range.

  • Minor repointing (1–2 faces): £350 – £500
  • Full stack repointing: £600 – £1,100
  • Repointing with new lead flashing: £800 – £1,400

All quotes are confirmed after a free roof inspection — no guesswork, no hidden extras. Request your free quote today.

Benefits of Professional Chimney Repointing

  • Stops leaks before they cause costly damage
  • Prevents loose or spalling bricks
  • Improves chimney stability and lifespan
  • Restores your home’s external appearance
  • Maintains property value and safety

Our Chimney Repointing Process

  1. Inspection: Assess the condition of joints, bricks, and leadwork.
  2. Preparation: Rake out loose mortar to the correct depth without damaging bricks.
  3. Repointing: Apply a matching mortar mix suited to the brick and age of the property.
  4. Finishing: Brush and clean joints for a neat, weather-sealed finish.
  5. Final check: Ensure all flashing, pots, and cowls are secure.

Why Choose S Harris Roofing in Dartford

  • Experienced roofers: Specialists in repointing brick and stone chimney stacks.
  • Local to Dartford: We know the typical property types and what mortar mix works best.
  • Quality materials: Proper sand/cement or lime-based mortars as appropriate.
  • Safety first: Scaffold or access towers used for clean, safe work at height.
  • Guaranteed workmanship: All repairs are backed by our satisfaction guarantee.

Visit Chimney Repairs or book a free survey to get started.

Chimney Repointing FAQs

How do I know if my chimney needs repointing?

Look for crumbling mortar, visible gaps between bricks, or vegetation growing out of joints. These are signs the mortar has failed and needs replacing.

Can you repoint just one side of a chimney?

Yes. We can target only the weathered faces if the rest is still sound. It’s a cost-effective solution when damage is localised.

How long does chimney repointing take?

Most repointing jobs are completed in one to two days, depending on the size and height of the stack.

Does repointing stop chimney leaks?

It often does, but if lead flashing or haunching is also failing, we’ll repair those at the same time to guarantee a watertight result.

What type of mortar do you use?

We match the original mortar as closely as possible — using lime mortar for older properties and modern mixes where appropriate.

Do you provide a warranty on chimney repointing?

Yes, all repointing and associated repairs come with a written workmanship guarantee for your peace of mind.

Can you repoint during winter?

Yes, as long as the temperature stays above freezing and conditions are dry. We plan around weather for proper curing.

Chimney Repair FAQs

How quickly can you attend a chimney leak in Dartford?

For active leaks, we aim to survey within a few working days. If water ingress is severe, we can arrange temporary weatherproofing while we book the repair.

Do I always need scaffolding for chimney repairs?

Not always. Minor lead or pointing work can sometimes be completed from ladders with proper safety measures. Taller stacks or full rebuilds usually require scaffold.

Will repointing stop my leak?

If the leak is caused by failed mortar, repointing helps. If the issue is split lead flashing or a missing cowl, we’ll address those specifically. We fix the cause, not just the symptom.

What mortar do you use for repointing?

We match the correct mortar type to your brick and age of property, avoiding overly hard mixes that can damage old brickwork.

Can you replace damaged chimney pots and add a cowl?

Yes. We can replace pots, re-bed them securely, and fit the correct cowl or cap to prevent rain ingress and bird nesting.

How long do chimney repairs take?

Small lead or pointing jobs can often be completed in half a day to a day. Rebuilds and removals take longer depending on scope and access.

Do you provide photos of the work?

Yes. We supply before and after photos so you can see exactly what was done.
