Finding a roofing company in London is not difficult. Finding the right roofer for your particular problem, property and budget is much harder.
Someone with rainwater coming through a ceiling needs a different service from a homeowner planning to replace an ageing slate roof. A Victorian terrace may require different materials and expertise from a modern extension with an EPDM flat roof. And two roofing quotations that appear similar can become very different once scaffolding, waste disposal, insulation, leadwork and unexpected timber repairs are included.
For this 2026 guide, Companies.London reviewed publicly available company information, business records, roofing services, trade-directory information, London coverage and customer-review patterns rather than simply repeating claims from contractors’ own websites.
Our research also analysed 424 substantive public customer reviews across the shortlisted businesses to identify recurring themes around workmanship, communication, quote accuracy, cleanliness, punctuality and aftercare.
The purpose of this guide is therefore not simply to name roofing companies. It is to help you answer three questions:
What roofing work do I actually need?
What should it reasonably involve and cost?
Which London roofing company appears suitable for that type of job?
Need a Roofer Urgently? Start Here
If your roof is leaking right now, do not begin by comparing ten companies.
First establish whether there is an immediate safety risk.
An active leak becomes more serious when water is close to electrical fittings, the ceiling is visibly sagging, tiles or masonry are falling, or the roof structure itself appears distorted.
Keep people away from visibly unsafe areas and move furniture, electronics and valuables away from water where this can be done safely.
Do not climb onto a wet, storm-damaged or unstable roof yourself.
Where there is smoke, fire, a serious electrical hazard or an immediate structural danger, use the appropriate emergency service rather than waiting for a roofing contractor.
For an ordinary but serious roof leak, an emergency roofer may initially concentrate on making the building safe and weather-resistant. The permanent repair can follow after the roof has been properly inspected.
Before the roofer arrives
If it is safe:
- Photograph the water ingress.
- Photograph damaged ceilings, walls and belongings.
- Take exterior images only from a safe ground-level position.
- Keep receipts for any emergency work.
- Contact your buildings insurer if you expect to make a claim.
The insurer may want to know about the damage before permanent repairs begin.
Which Type of Roofing Company Do You Need?
Different roofing companies specialise in different jobs.
This distinction matters because the company best equipped for a complete £10,000+ re-roof is not necessarily the company you need for a small repair.
Roofing Companies in London We Researched
Our research found meaningful differences between the shortlisted businesses in terms of specialism, geographic coverage and publicly available evidence.
Rather than claiming that one company is automatically the “best roofer in London”, we have identified circumstances in which each company may be worth considering.
Quick Comparison
Our research showed that company specialisms and coverage vary considerably, making a job-specific shortlist more useful than a simple number-one-to-number-ten ranking.
Bernard Andrews Roofing
Bernard Andrews Roofing may be relevant for homeowners with period properties, slate roofs, leadwork or chimney-related roofing problems.
The underlying research identified Bernard Andrews Roofing Limited as an active company incorporated on 13 December 2022. The research also recorded pitched and flat roofing, conservation slating, leadwork, chimney repairs and drone inspections within its published service scope.
Its stated London coverage included areas such as Kensington & Chelsea, Westminster, Camden, Islington, Richmond, Wandsworth and Hammersmith & Fulham.
Consider Bernard Andrews if:
Your property has traditional slate, lead detailing, chimneys or heritage considerations and you want a more detailed planned inspection.
Ask before hiring:
What guarantee applies specifically to your project?
Is any insurance-backed protection included?
Does the proposed material comply with any conservation requirements affecting your property?
Watkins Flat Roofing
Watkins Flat Roofing is different from many general roofers because its public service information focuses strongly on flat-roof construction and waterproofing systems.
The research identified EPDM, single-ply and other flat-roof work among its published services.
That makes it more relevant for a leaking extension, garage or flat-roofed addition than for a homeowner looking for traditional slate or tile restoration.
Consider Watkins if:
You specifically need a flat roof inspected, repaired or replaced.
Ask before hiring:
Which flat-roof system do you recommend?
Why is that system appropriate for this particular roof?
Will the existing deck be inspected?
How will falls and drainage be dealt with?
What workmanship and manufacturer warranties will apply?
London Roofing Ltd
London Roofing Ltd appears better aligned with larger roofing projects, re-roofing, landlords and property-management work.
Its researched service profile included commercial renewals, slate and tile roofing and work associated with managed properties. Its stated coverage included Wandsworth, Lambeth, Southwark, Richmond, Kingston, Ealing, Hillingdon and Hammersmith & Fulham.
The company’s long trading-history statements should be distinguished from the incorporation history of any particular corporate entity. That distinction is part of our evidence-classification methodology.
Consider London Roofing Ltd if:
You are planning a substantial re-roof, managing rental properties or dealing with a larger residential/commercial roofing project.
Ask before hiring:
Is my project large enough to fit your current workload?
Is scaffolding included?
Who manages Building Regulations compliance?
What documentation and guarantees will be provided at completion?
Element Roofing London
Element Roofing London appears particularly relevant to standard domestic repair and residential roofing work.
The research associated it with domestic roof repairs, leak work, residential re-roofing and gutter maintenance. Its stated area coverage included Lewisham, Greenwich, Southwark, Tower Hamlets, Hackney, Newham, Bexley, Bromley and Croydon.
In the customer-review sample analysed during the research, recurring positive themes included quotation consistency, punctuality and clearing up after work, while busy winter periods were associated with longer waits.
Consider Element Roofing if:
You need general residential repair or planned re-roofing, particularly in south or east London.
Ask before hiring:
What is the current lead time?
Is urgent attendance available?
Does the quotation include all access requirements?
Ace Roofing Company Ltd
Ace Roofing appeared in the research as a South London domestic roofing option, with published services covering maintenance, leadwork and flashing repairs.
The dataset associated the business with a South London base and stated coverage in Southwark, Lambeth, Lewisham, Croydon, Hackney and Tower Hamlets.
Consider Ace Roofing if:
You have a relatively conventional domestic roofing, lead or flashing problem in its service area.
Ask before hiring:
Do you currently cover my postcode?
Is an inspection required before quoting?
What written guarantee applies to the repair?
247 Roofing Solutions
247 Roofing Solutions is relevant to a different search intent: emergency roofing.
The research identified publicly advertised 24/7 and same-day services together with temporary make-safe capability.
An emergency claim does not mean a company can necessarily attend every postcode immediately. Availability can depend on workload, weather and travel conditions.
Consider 247 Roofing Solutions if:
Water ingress, storm damage or another urgent roof problem requires a rapid response.
Ask before hiring:
What is the call-out charge?
What does the emergency visit include?
Is the first visit only a temporary repair?
Will a separate fixed quotation be provided for permanent work?
What Did We Learn From 424 Customer Reviews?
Review scores by themselves can be misleading.
A difference between 4.7 and 4.8 stars does not tell you how well a contractor communicates when unexpected timber damage is found halfway through the job.
For this research, 424 substantive public client reviews were aggregated across sources including Google Maps, Checkatrade and Trustpilot.
The reviews were coded around themes such as:
quote accuracy, cleanliness, punctuality, communication, unexpected additional costs and aftercare.
Across the research, two particularly important consumer concerns emerged:
Clear evidence of the actual roofing defect
and
clarity about what the quotation includes.
The research also found complaints around extended project timelines and costs changing after old roofing materials had been removed.
That leads to one simple rule:
If a contractor recommends expensive additional work on a part of your roof you cannot see, ask them to show you the problem.
Photographs and video can be extremely useful.
Repair or Replace Your Roof?
This is one of the biggest decisions homeowners face.
Do not allow roof age alone to make the decision.
An old roof can sometimes remain serviceable with targeted repairs. A newer roof can require major work if it was badly installed or has suffered structural damage.
A Repair May Be Realistic When:
The defect is clearly localised.
Examples might include:
- one or several slipped tiles;
- a local flashing problem;
- an isolated puncture or leak;
- a limited section of damaged covering.
Replacement Becomes More Relevant When:
Damage is widespread.
Leaks repeatedly occur in different places.
Large areas of underlay or roof covering have failed.
Supporting battens or structural timber have deteriorated significantly.
Repeated previous repairs are no longer solving the problem.
Our repair-versus-replacement research emphasised that a physical inspection is necessary, particularly for complex and older London properties.
Before Agreeing to a Complete Roof Replacement, Ask:
Can you show me where the roof has failed?
Can you provide photographs or video?
Are the problems localised or widespread?
Is the supporting structure affected?
Why would a repair not provide a reasonable solution?
What can only be assessed after the existing roof is stripped?
These questions can help protect you against unnecessary work.
How Much Does Roofing Cost in London in 2026?
There is no honest one-price answer.
London roofing costs vary according to:
roof size, pitch, material, building height, access, scaffolding, waste disposal, chimneys, valleys, leadwork, insulation and hidden deterioration.
The research found that the main shortlisted contractors generally required a property-specific quotation instead of publishing universal fixed prices for major projects.
Indicative London roofing costs
Our broader London research found new-roof costs for a standard terraced property commonly appearing between roughly £6,000 and £18,000, depending heavily on material and structural requirements.
Examples from the collected evidence included approximately:
These are research benchmarks, not quotations.
The earlier London cost research showed significant variation between broad market averages and more complex slate or structural projects.
Why Are London Roofing Quotes So Different?
Two houses of the same size can produce very different quotations.
Scaffolding
Safe access can be a major cost.
London terraced streets, narrow pavements, taller properties and difficult rear access can all increase scaffolding complexity.
Ask:
Is scaffolding included in this quote?
Does the price include the full expected hire period?
Who pays if the scaffold remains longer because of contractor delays?
Roofing Material
Natural slate can cost substantially more than standard concrete tiles.
Flat-roof systems also vary.
Comparing an EPDM quotation against GRP or felt without understanding the system is not a like-for-like comparison.
Chimneys and Leadwork
A roof with several chimneys, valleys and complex junctions normally requires more detailing than a simple roof plane.
Waste Removal
Old tiles, membrane, timber and other roofing waste must be removed.
Check whether skips and disposal are included.
Access Restrictions
Parking and material handling can be more difficult in London than on an open suburban site.
Hidden Timber Deterioration
No contractor can always see every batten, joist or section of decking before the old covering is removed.
This is why a professional quote should contain a clear process for additional work.
How Long Does Roofing Work Take?
The working time depends on the scale of the job.
The research identified broad examples such as:
Weather, scaffolding, hidden defects, material availability and local access arrangements can increase the total project period.
Therefore, ask two questions:
How long will the roofing work itself take?
and
How long from scaffolding installation to final removal?
Those are not necessarily the same period.
What Should a Professional Roofing Quote Include?
This is one of the most important sections of this guide.
Do not compare quotations by price alone.
Compare scope.
Our research repeatedly identified scope, material specifications, scaffolding, waste and payment terms as important points to establish before accepting a quotation.
Quote or Estimate?
Ask which one you have been given.
A preliminary estimate may change as more information becomes available.
A detailed quotation for a defined scope is much more useful when comparing contractors.
However, roofing can involve hidden components.
For example, removing tiles might expose deteriorated battens that could not previously be inspected.
A good contract should therefore explain:
how hidden problems will be documented;
how additional work will be priced;
and who must approve it.
Never allow “we found more problems” to become an open-ended permission to increase the bill.
Should You Always Choose the Cheapest Roofing Quote?
No.
You should not automatically choose the most expensive either.
Consider two hypothetical quotations:
Quote A: £7,900
Quote B: £9,100
B initially appears £1,200 more expensive.
But suppose B includes:
full scaffolding;
waste removal;
specified roofing materials;
new lead flashing;
regulatory documentation;
and a clearly defined guarantee.
If Quote A leaves these unclear, you do not yet know which contractor is actually cheaper.
The proper comparison is:
same scope versus same scope
not simply:
total versus total
Roofing Guarantees Explained
Roofing guarantee terminology can confuse homeowners.
Three different protections may be involved.
Workmanship Guarantee
This covers specified problems associated with the contractor’s installation, subject to the written terms.
Ask:
How long does it last?
What is excluded?
Is it transferable?
Who handles a claim?
Manufacturer Warranty
This concerns the roofing product or system.
It may not automatically pay for all labour involved in removing and reinstalling defective material.
Read the conditions.
Insurance-backed Guarantee
An insurance-backed guarantee can provide specified protection if the contractor later ceases trading, subject to the actual insurance terms.
Important: NFRC membership is not automatically an IBG
Do not assume that seeing an NFRC badge means your roof automatically comes with a long insurance-backed guarantee.
Ask for:
- the actual policy
- the insurer
- the duration
- the exclusions
and proof that your individual roofing project has been registered where required.
How to Verify a Roofing Company?
Do not depend only on the contractor’s website.
For larger projects, check information independently.
Companies House
Useful for checking:
- legal entity
- company number
- company status
- incorporation date
- registered office
But remember:
company age and individual experience are not necessarily the same thing.
A contractor may have 20 years of roofing experience while operating through a company incorporated three years ago.
The important point is to describe those facts correctly.
Trade memberships
If the roofer displays NFRC, TrustMark or another trade logo, check the official member directory.
A logo on a website is not independent proof.
Our own research followed this verification approach rather than automatically treating contractor website claims as facts.
Building Regulations: What Should You Ask?
Building Regulations may be relevant to substantial roofing work.
The requirements depend on the exact project, so avoid simplistic statements such as:
“Every roof needs permission.”
or:
“No roof replacement needs Building Control.”
Ask the roofer:
Does my project need Building Regulations notification or certification?
Who is handling it?
Can you self-certify this particular work through an applicable competent-person scheme?
What certificate will I receive after completion?
Keep the certificate with the property documentation.
It may become relevant when you sell or remortgage the property.
Conservation Areas and Listed Buildings
London contains a large amount of historic housing.
That means homeowners need to be particularly careful before changing roof materials or altering the external appearance of a protected property.
Ordinary maintenance and significant alteration are not the same thing.
Changing natural slate to a visibly different material, installing rooflights, changing dormers or modifying other prominent roof features can require further checks depending on the property and local planning controls.
Research across London boroughs found specific controls affecting roofs in locations including Westminster, Richmond, Islington, Camden and Haringey.
If your property is:
listed;
inside a conservation area;
or affected by an Article 4 Direction,
check its exact planning status before approving a significant material or design change.
Common London Roof Types
Victorian Terraces
Traditional London terraces often feature steep pitched roofs and slate.
Potential issues can include:
- slipped slates
- ageing fixings
- leadwork
- chimneys
- valleys
and parapet junctions.
If the property is protected, replacement materials may also need greater planning consideration.
1930s Houses
Tile roofs are common.
During significant refurbishment, the contractor may also need to consider underlay, ventilation, insulation, battens and timber condition rather than replacing only what is visible from outside.
Rear Extensions
Flat roofs are extremely common.
- Possible problems include
- ponding water
- split seams
- failed roof-to-wall junctions
- outlet problems
and deterioration of the underlying deck.
Period mansard roofs
Mansard and dormer-heavy roofs require more complex detailing.
For this type of property, relevant specialist experience can be more important than simply choosing the closest roofer.
10 Roofing Red Flags
Be cautious if a roofing contractor:
- Knocks on your door claiming they happened to notice serious roof damage.
- Says the price is available “today only”.
- Pressures you to approve a full replacement immediately.
- Refuses to provide an itemised written quotation.
- Cannot clearly identify the business you are contracting with.
- Shows expensive damage but refuses to provide photographs.
- Demands substantial additional work without a revised price.
- Displays accreditations you cannot verify.
- Encourages you to ignore legal or regulatory requirements to save money.
- Demands final payment while important agreed work remains incomplete.
The wider research found similar recurring concerns around doorstep approaches, high-pressure sales, unverifiable accreditation and vague pricing.
A warning sign does not automatically establish fraud.
It tells you to verify before signing or paying.
10 Questions to Ask a Roofer
Before accepting a substantial roofing quotation, ask:
1. What Exactly is Wrong With My Roof?
Ask for an explanation rather than a generic statement such as “the whole thing is finished”.
2. Can You Show Me the Damage?
Photographs or video are useful when defects are inaccessible.
3. Why Are You Recommending Repair or Replacement?
The contractor should be able to explain the reasoning.
4. What Exactly is Included?
Confirm materials, scaffolding, waste and finishing work.
5. What Could Increase the Price?
Understand this before stripping begins.
6. How Will Additional Work Be Approved?
Prefer a written variation process.
7. What Guarantee Will I Receive?
Ask for actual terms.
8. Is Insurance-backed Protection Available?
Do not assume.
9. Who Handles Building Regulations Requirements?
Establish responsibility before starting.
10. What is the Payment Schedule?
Know what each payment corresponds to.
Should You Get Three Roofing Quotes?
For a planned full roof replacement, comparing several quotations is usually useful.
It can reveal differences in:
- materials
- scope
- scaffolding
- guarantees
- regulatory arrangements
and the treatment of unexpected work.
But an emergency leak is different.
If your property is actively taking in water, the first priority may be temporary weatherproofing.
You can obtain several comparable quotations for the permanent solution once the immediate problem has been controlled.
How We Researched the London Roofing Market
Transparency matters for a comparison article.
Companies.London therefore used a multi-tiered research methodology rather than treating every online source equally.
1. Source Hierarchy
Level 1 — Government and Regulatory Sources
Highest priority was given to sources such as:
- GOV.UK
- Companies House
- Planning Portal
- London borough information
- Trading Standards
- and other relevant public bodies
These were used particularly for legal/company information and consumer requirements.
Level 2 — National Trade Bodies
We used sources and directories associated with organisations such as:
NFRC;
TrustMark;
and the Federation of Master Builders.
Where a company claimed accreditation, the goal was to distinguish the company’s claim from information identifiable in an independent directory.
Level 3 — Technical and Market Evidence
Technical information was supplemented using sources such as:
professional surveying guidance;
manufacturer specifications;
trade technical guidance;
published market cost sources;
and public procurement information.
No single contractor website was treated as definitive evidence of the whole London roofing market.
How We Separated Facts From Marketing?
Every significant research finding was treated as one of five evidence types.
Verified Fact
Information supported by appropriate official, regulatory, local-authority or independently verifiable records.
Example:
a company’s incorporation date shown by Companies House.
Company-Stated Claim
Information published by the contractor itself but not established independently.
Example:
“50 years of combined roofing experience”.
That claim may be genuine, but it is not the same thing as a Companies House incorporation date.
Our Calculation
A value calculated from underlying public information.
Example:
calculating approximate company age using its incorporation date and the current year.
Our Analysis
A conclusion reached by comparing several sources.
For example:
identifying repeated consumer concerns across a large review sample.
Unverified
Information for which sufficiently transparent or consistent public evidence could not be found.
These claims were not treated as established facts.
How Customer Reviews Were Analysed?
The research included 424 substantive public review records across platforms including Google Maps, Checkatrade and Trustpilot.
Rather than simply calculating star ratings, reviews were organised into themes including:
- workmanship
- quote accuracy
- communication
- cleanliness
- punctuality
- unexpected additional costs
- and aftercare.
Very short ratings without useful project detail were treated as less informative than reviews describing the actual roofing work.
This means the review analysis is best understood as a structured sample of public customer sentiment, not a guarantee of the experience every future customer will receive.
How Conflicting Evidence Was Handled?
Roofing data frequently disagrees.
One national cost guide might suggest a lower average than a specialist London contractor dealing with slate roofs, high scaffolding and difficult access.
We did not assume one source must automatically be wrong.
Instead, differing evidence was examined in context.
Price differences may result from:
- roof size
- roofing material
- property height
- scaffolding
- access
- structural deterioration
- and the precise work included
Where evidence could not reasonably be reconciled, it was treated as conflicting rather than forced into a misleading single number.
Final Verdict: How Should You Choose a London Roofer?
Do not start with:
“Who is the cheapest?”
Start with:
“Who appears most appropriate for this particular problem?”
For an emergency leak, prioritise safe response and temporary protection.
For a flat roof, prioritise experience with the proposed waterproofing system.
For a Victorian or listed property, prioritise traditional materials and relevant period-property experience.
For a complete re-roof, prioritise scope, documentation, access planning, guarantees and regulatory compliance.
And regardless of which company you choose, remember one question:
Can you show me why this work is necessary?
A strong roofing company should be able to explain what is wrong, what it proposes to do, what materials it intends to use, what the quotation includes and what protections you receive afterwards.
That gives you far more useful information than a star rating, a marketing slogan or a “best roofer in London” badge.
Frequently Asked Questions
Who is the Best Roofing Company in London?
There is no company that is objectively best for every roofing job. A flat-roof specialist, emergency roofer and heritage slate contractor solve different problems. Start with your roof type and required work.
How Much Does a New Roof Cost in London?
Our collected evidence suggests a broad range from approximately £6,000 into the high teens for many London residential reroofing scenarios, with material, size, structural work and access being major variables. Obtain a property-specific inspection before budgeting around an online average.
How Much Does a Small Roof Repair Cost?
Our research identified roughly £250–£600 as a broad benchmark for some localised repair work, but actual costs depend heavily on access and the defect.
How Do I Know Whether My Roof Needs Replacing?
Ask for evidence showing why localised repair is not appropriate. Widespread covering failure, repeated leaks and significant underlying deterioration can make replacement more reasonable, but age alone should not determine the decision.
What Should I Do if My Roof is Leaking?
Keep people away from unsafe areas, protect possessions where safe, avoid climbing onto the roof and arrange professional assessment. If water affects electrics or there is an immediate danger of collapse, treat it as a safety issue rather than an ordinary roofing repair.
Should I Choose an NFRC Roofer?
NFRC membership can be one useful verification point, but it should not replace checking the quotation, scope, guarantee and suitability of the company for your particular job.
Does NFRC Membership Automatically Provide an Insurance-backed Guarantee?
No. Trade membership and an insurance-backed guarantee are different things. Ask whether an IBG applies to your particular project and request the actual policy documentation.
Should a Roofer Provide Photos?
There is no need to demand a drone survey for every simple repair, but clear visual evidence is extremely useful when you are being asked to approve expensive work on an inaccessible part of the roof.
Should I Pay a Roofing Deposit?
Some contractors request deposits for larger projects or material commitments. There is no universal deposit percentage that fits every roofing job. Make sure the amount, purpose and later payment stages are documented before paying.
How Long Does a New Roof Take?
A straightforward terraced re-roof may involve several working days, while complex structural or heritage projects can take considerably longer. Weather, scaffolding, access and hidden deterioration can extend the total project period.
