Top Roofing Contractors in London

Roofing work can range from replacing a few slipped tiles to renewing an entire pitched or flat roof, upgrading insulation, rebuilding chimney details or installing a new waterproofing system.

The right contractor should be selected according to the roof type, scope, building age, access and level of technical responsibility rather than a generic claim of being “trusted”. A domestic repair company may be suitable for a leaking terrace roof, while a listed building, green roof or large commercial project may require a contractor with different accreditation, design capability and insurance.

The six contractors below provide distinct coverage across central, east, south-east and west London, including emergency repairs, domestic re-roofing, flat-roof systems and larger commercial work.

What distinguishes a suitable roofing contractor?

A suitable contractor should inspect the roof, explain the proposed repair or replacement method and provide a written quotation before substantial work begins.

Check:

• Full legal business name
• Companies House status
• Trading address
• Public-liability insurance
• Employers’ liability where staff are employed
• Professional-indemnity insurance where design advice is provided
• NFRC or other trade-body membership where claimed
• Relevant manufacturer approvals
• Roof-system specification
• Scaffolding
• Waste removal
• Building Control responsibility
• Planning or listed-building requirements
• Ventilation and insulation
• Workmanship guarantee
• Manufacturer warranty
• Insurance-backed guarantee
• Payment schedule
• Variations
• Complaints procedure
• VAT

NFRC advises homeowners to obtain written quotations and consider an insurance-backed guarantee because a contractor’s own guarantee can become ineffective if the business later stops trading.

At a glance

Trade membership and service claims should be checked again before appointment because status and personnel can change.

How much does roofing cost in London?

Roofing prices vary according to access, area, structure, material, scaffolding and the condition discovered after coverings are removed.

Indicative London ranges include:

• Minor tile or slate repair: £200–£700
• Localised leak investigation and repair: £250–£1,000+
• Gutter repair or replacement: £250–£1,500+
• Chimney flashing or leadwork: £400–£2,000+
• Small flat-roof replacement: £2,000–£6,000+
• Larger flat roof: £5,000–£15,000+
• Pitched roof replacement: £8,000–£25,000+
• Natural slate, complex detailing or heritage work: potentially much higher
• Scaffolding: commonly a significant separate cost

A quotation should distinguish labour, materials, scaffolding, skips, permits, insulation, timber repairs, VAT and any provisional sums.

Website

Golden Roofing Expert Limited provides repair, replacement and maintenance services across London.

Its website covers pitched and flat roofs, leak repairs, gutters, fascias, soffits and new installations. The company is not solely a flat-roof specialist, although flat-roof work remains a prominent part of the service.

Golden Roofing advertises a 20-year guarantee on new roof and flat-roof installations. Customers should ask whether this is a workmanship guarantee, manufacturer warranty, insurance-backed guarantee or combination of these.

A long written guarantee is useful only where the contracting company, covered defects, exclusions, claim procedure and transferability are clear. Materials may carry a separate manufacturer warranty with different conditions.

The business accepts emergency enquiries and offers quotations after inspection. For urgent leaks, customers should establish whether the initial work is a temporary weatherproofing measure or the permanent repair.

Pros

• Repairs, maintenance and complete roof replacements
• Flat and pitched roofing services
• Emergency enquiries accepted
• Long guarantee period advertised for new installations

Best for: London homeowners comparing repair and replacement options across flat and pitched roofs.

What to confirm: Request the legal entity on the contract, guarantee document, insurance details, complete specification and payment schedule.

London Roofing Specialist Solutions

Address: Pavilion, 96 Kensington High Street, London W8 4SG
Phone: 020 7205 4557
Company: London Roofing Specialist Solutions Ltd, company number 14012031
Professional membership: NFRC member since 2025
NFRC-listed disciplines: Slating and tiling, fully supported lead and single-ply roofing
Website

London Roofing Specialist Solutions provides domestic, commercial and new-build roofing work across London and surrounding areas.

The company’s service range includes pitched roofs, flat roofs, repairs, slating, tiling, leadwork and single-ply systems. Its NFRC listing identifies commercial and industrial work, domestic refurbishment and new-build housing among its market sectors.

NFRC membership is useful because members are vetted and must provide evidence of appropriate insurance and technical competence in the listed disciplines. It does not mean that every possible roofing system falls within the scope of the membership.

The company states that it was founded in 1998. Prospective clients should use the active legal company name and number shown on the quotation rather than relying only on trading-history language.

For major re-roofing, the quotation should explain Building Control notification, insulation, ventilation, structural checks and whether the contractor can self-certify through a competent-person scheme.

Pros

• Current NFRC membership
• Domestic, commercial and new-build sectors
• Pitched, lead and single-ply disciplines
• Central and west London contact base

Best for: Clients seeking an NFRC-listed contractor for pitched, lead or single-ply roofing in London.

What to confirm: Check the live NFRC entry, exact legal entity, competent-person status, guarantee type and responsibility for Building Control.

DJM Roofing Ltd

Address: Euro Suite, 16–18 Woodford Road, London E7 0HA
Phone: 020 8502 5080 or 07881 530012
Format: Family-run roofing contractor serving east London and Essex
Published history: Established in 1982
Services: Repairs, pitched roofs, flat roofs, leadwork, chimneys, fascias, soffits and guttering
Website

DJM Roofing is an east London roofing business covering repairs, replacements and roofline work.

Its services include slate and tiled pitched roofing, flat-roof systems, storm-damage repair, leadwork, chimneys, fascias, soffits and guttering. The company also accepts emergency repair enquiries.

DJM states that workmanship is guaranteed. As with any contractor guarantee, customers should ask for the period, scope, exclusions and claim procedure before work begins.

The company’s long operating history is relevant, but customers should still obtain an up-to-date contract, insurance certificate and specification for the particular project.

For leak repairs, the quotation should distinguish visible damage from the possible source of water ingress. Water can travel through roof voids and appear internally away from the original defect.

A repair may also reveal rotten battens, decking or structural timber after coverings are removed. The contract should explain how such variations are approved and priced.

Pros

• Long-established east London business
• Pitched, flat and roofline services
• Leadwork and chimney repairs
• Emergency enquiries and free quotations

Best for: East London and Essex homeowners needing traditional repairs, re-roofing or roofline work.

What to confirm: Ask for insurance, guarantee terms, a photographic specification and the process for approving hidden timber repairs.

L.H Roof Services Ltd

Address: 11 Maud Cashmore Way, London SE18 5QS
Phone: 07481 138265
Company: L.H Roof Services Ltd, company number 15443640
Coverage: Woolwich, Charlton, Plumstead, Greenwich, Abbey Wood, Eltham, Welling, Bexleyheath and north Kent
Services: Repairs, pitched and flat roofs, leadwork, chimneys, maintenance and roofline work
Website

L.H Roof Services is a south-east London contractor serving SE18 and nearby London and Kent areas.

The company handles slate and tiled roofs, flat roofing, leaks, leadwork, chimneys, gutters, fascias, soffits and roof inspections. It also advertises a 24-hour emergency call-out service.

Its clearly defined local coverage can be useful where a contractor needs to revisit a repair or inspect a developing leak. Customers outside the stated area should confirm travel and availability before arranging a survey.

The business advertises domestic and commercial work. A residential homeowner should still ask who will attend, whether employees or subcontractors are used and what insurance applies.

The earlier article described cedar shingles and bee removal as central specialisms, but the current service pages focus more clearly on conventional repairs, flat roofing, slating, tiling and roofline work. The entry therefore reflects the verified current service range.

Pros

• Defined south-east London coverage
• Flat and pitched roof services
• Emergency call-out availability
• Active limited company details can be verified

Best for: Homeowners in Woolwich, Greenwich and surrounding south-east London areas seeking a local repair or replacement contractor.

What to confirm: Request evidence of insurance, the exact guarantee, emergency call-out fee and whether scaffolding or permits are included.

VDM Roofing Ltd

Registered office: 44 Syon Park Gardens, Isleworth TW7 5NB
Company: VDM Roofing Ltd, company number 06714965
Professional membership: NFRC member since 2018
Coverage: London, including west and south-west boroughs
NFRC-listed systems: Slating and tiling, single ply, green roofing, bitumen membranes and liquid waterproofing
Website

VDM Roofing is a family-run contractor based in Isleworth and serving London.

Its service range includes roof repairs, pitched-roof replacement, flat roofs, leadwork, gutters and maintenance. The NFRC listing also identifies green-roof, single-ply, bitumen and liquid-waterproofing disciplines.

This broader flat-roof system range can be useful where a homeowner needs more than a standard felt replacement or where an extension roof requires a particular build-up.

Green roofs require careful assessment of structure, waterproofing, drainage, root resistance and maintenance. A contractor should not add a green-roof build-up without confirming that the supporting structure is suitable.

VDM’s NFRC membership is listed for domestic refurbishment and replacement. Customers should verify whether any larger commercial or design-led element falls within the contractor’s current insurance and competence.

Pros

• NFRC member since 2018
• West London base
• Pitched, flat, liquid and green-roof systems
• Repairs and complete refurbishment work

Best for: West and south-west London homeowners needing a contractor with several flat-roof and waterproofing options.

What to confirm: Ask which system is proposed, who designs the build-up, whether an insurance-backed guarantee is available and how drainage is handled.

Element Roofing Co Ltd

London base: South-east London
Professional membership: NFRC member since 2007
Market sectors: Domestic refurbishment, commercial and industrial roofing
Systems: Slating, tiling, lead, metal, single ply, green roofs, bitumen, liquid coatings, mastic asphalt, GRP and cladding
Published price: Survey and quotation required
NFRC profile

Element Roofing Co provides a wider technical range than most small domestic contractors in this selection.

Its NFRC profile lists pitched roofing, flat and low-pitched systems, metal roofing, green roofing, mastic asphalt, GRP, liquid waterproofing and cladding. The company works across residential, commercial and industrial sectors.

This breadth is useful for mixed roofs, larger blocks, commercial buildings or projects involving several materials. It also makes the written specification particularly important because the contractor may be proposing one of many possible systems.

The NFRC listing states more than 30 years of industry experience and membership since 2007. Customers should still verify the live member status and identify which listed discipline applies to the proposed work.

Where the contractor is asked to design drainage, insulation, falls, waterproofing or interfaces with cladding, professional-indemnity cover may be relevant in addition to public-liability insurance.

Pros

• NFRC member since 2007
• Domestic, commercial and industrial capability
• Broad pitched, flat, metal and cladding systems
• Suitable for technically varied projects

Best for: Larger, mixed-system or commercial projects requiring more than a straightforward domestic tile repair.

What to confirm: Ask for the named system, manufacturer approval, design responsibility, professional-indemnity cover and project-specific guarantee.

NFRC membership and contractor checks

NFRC members are vetted before joining and periodically reassessed. The organisation checks areas including trading history, technical competence, insurance and standards.

Membership should still be checked against:

• Current company name
• Membership status
• Market sector
• Listed roofing discipline
• Complaints scope
• Competent-person status
• Location
• Contact details

A company can be an NFRC member for selected disciplines without being approved for every type of roof.

Contractor guarantee, manufacturer warranty and insurance-backed guarantee

Workmanship guarantee

Provided by the contractor and covers specified installation defects for a stated period.

Manufacturer warranty

Provided under the roofing-system manufacturer’s terms. It may require an approved installer, inspections and specific maintenance.

Insurance-backed guarantee

Independent protection that may respond if the contractor stops trading, subject to policy terms.

Ask for all documents before final payment.

Building Regulations

Replacement roofing often involves Building Regulations.

Approval may be required where:

• A substantial proportion of the roof is replaced
• A thermal element is renovated
• Insulation must be upgraded
• The replacement material changes the structural loading
• Fire performance changes
• A rooflight is installed
• Structure is altered

A contractor registered under an appropriate competent-person scheme may be able to self-certify qualifying work. Otherwise Building Control may need to be notified.

The quotation should identify who is responsible for compliance and certification.

Planning permission and listed buildings

Like-for-like roof repair often does not require planning permission, but restrictions can apply where:

• Roof height changes
• The profile changes
• A dormer or roof extension forms part of the project
• Materials change significantly
• The property is listed
• The building is in a conservation area
• Article 4 directions apply
• Solar panels or rooflights form part of the project
• A flat is involved rather than a house

Listed-building consent can be required even for work that appears visually minor.

Flat-roof systems

Common systems include:

Reinforced bitumen membrane

A multi-layer felt-based system installed with torch, cold-applied or self-adhesive methods.

EPDM

A synthetic rubber membrane commonly used on domestic extensions and garages.

GRP

A fibreglass system formed on a suitable deck.

Single ply

A proprietary sheet membrane commonly used on larger or commercial roofs.

Liquid waterproofing

A seamless coating system used in certain refurbishment and detailing situations.

Mastic asphalt

A traditional robust waterproofing material requiring specialist installation.

The right system depends on deck, falls, upstands, outlets, foot traffic, fire safety and maintenance.

Warm roof and cold roof construction

Warm roof

Insulation sits above the structural deck. This commonly reduces condensation risk and avoids the need for ventilation below the deck when correctly designed.

Cold roof

Insulation sits below the deck, leaving a ventilated void. Detailing and ventilation must be designed carefully.

A contractor should explain the build-up rather than quote only the visible waterproofing layer.

Pitched roofs

Pitched roof work may include:

• Tiles
• Natural slate
• Fibre-cement slate
• Battens
• Underlay
• Flashings
• Valleys
• Ridge and hip systems
• Ventilation
• Insulation
• Chimneys
• Rooflights
• Timber repairs

Changing from slate to a heavier tile can require structural assessment.

Roof surveys and leak diagnosis

A useful survey should identify:

• Roof covering
• Approximate age
• Visible defects
• Flashings
• Chimneys
• Valleys
• Outlets
• Gutters
• Deck or timber condition where visible
• Ventilation
• Insulation
• Access limitations
• Recommended repair
• Alternative options
• Photographs

A visual survey cannot always identify concealed moisture or timber decay without opening the roof.

Emergency repairs

Emergency call-outs commonly provide temporary protection rather than a complete repair.

Ask:

• Call-out fee
• Included labour
• Materials
• Night or weekend premium
• Temporary covering
• Follow-up survey
• Permanent repair quote
• Photographic evidence
• Payment method

Do not authorise a full replacement solely because an emergency contractor says the roof cannot be repaired without a proper written assessment.

Scaffolding and access

Roofing work may require:

• Independent scaffold
• Tower scaffold
• Edge protection
• Mobile access platform
• Pavement licence
• Hoarding
• Neighbour access
• Parking suspension
• Skip permit

The quotation should identify who appoints and pays the access contractor and how long the scaffold remains.

Party walls and neighbour access

Roofing work can affect adjoining owners where:

• Chimneys are shared
• Parapets are repaired
• Flashing enters a party wall
• Scaffolding crosses neighbouring land
• Roof structures are altered
• An extension abuts the boundary

Legal advice or a party-wall surveyor may be needed for some structural work. Do not assume the roofer manages every neighbour issue.

Insurance and liability

Ask for current evidence of:

• Public liability
• Employers’ liability
• Professional indemnity where design is undertaken
• Contract works cover
• Scaffolding insurance
• Subcontractor insurance

Check whether the policy limit is adequate for the property and project.

Quotations and provisional sums

A clear quotation should include:

• Survey findings
• Scope
• Area
• Material and manufacturer
• Number of layers
• Insulation
• Deck replacement
• Timber allowance
• Flashings
• Outlets
• Scaffolding
• Waste
• Building Control
• VAT
• Start and completion assumptions
• Guarantee
• Payment stages

A provisional sum is an allowance, not a fixed final price. Ask how variations will be documented.

Deposits and payment stages

Avoid paying the full price before work begins.

A staged structure may include:

• Small booking deposit
• Payment when scaffold and materials arrive
• Progress payment
• Final balance after inspection and documents

Large material deposits should be supported by a clear contract and payment protection where available.

Hidden defects and variations

Once coverings are removed, contractors may find:

• Rotten decking
• Damaged rafters
• Inadequate falls
• Wet insulation
• Failed outlets
• Unsafe chimney masonry
• Previous non-compliant work
• Asbestos-containing materials

Agree that no significant variation proceeds without photographs, explanation and written price approval.

Asbestos

Older roofs may contain asbestos cement, asbestos insulation board or other asbestos-containing materials.

Suspected material should be assessed before disturbance. Removal and disposal requirements depend on the material and condition.

A roofing quotation should not assume ordinary skip disposal where asbestos may be present.

Chimneys and leadwork

Chimney leaks may arise from:

• Flashing
• Pointing
• Flaunching
• Pots
• Caps
• Masonry
• Condensation
• Internal flues

Leadwork should follow appropriate detailing and sizing. Long sheets can crack if thermal movement is not accommodated.

Gutters, fascias and soffits

Roofline work should consider:

• Gutter fall
• Outlet size
• Downpipe capacity
• Overflow route
• Fascia condition
• Soffit ventilation
• Rafter ends
• Asbestos soffits
• Connection to drainage

Replacing gutters without addressing poor falls or blocked drainage may not solve overflow.

Green roofs

A green roof requires:

• Structural capacity
• Waterproofing
• Root barrier
• Drainage
• Filter layer
• Growing medium
• Planting
• Edge detailing
• Irrigation where needed
• Maintenance

The vegetation layer should not be installed until the waterproofing has been tested.

Solar panels and roofing

Before re-roofing, tell the contractor about existing solar panels.

The work may require:

• Electrical isolation
• Panel removal
• Temporary storage
• Mounting-system review
• New flashings
• Reinstallation
• MCS-certified electrical work
• Warranty checks

Roof work and solar work may involve separate contractors and guarantees.

Questions to ask before appointment

• What is your legal company name?
• Are you an NFRC member?
• Which roofing disciplines are covered?
• Are you insured?
• Who will undertake the work?
• Do you use subcontractors?
• Which roof system do you recommend?
• Why is it suitable?
• Is Building Control required?
• Who handles certification?
• Is scaffolding included?
• What guarantee is provided?
• Is an insurance-backed guarantee available?
• What can change the price?
• How are variations approved?
• What is the payment schedule?
• How will waste be disposed of?
• What is the complaints procedure?

Common warning signs

Be cautious where a contractor:

• Demands full cash payment in advance
• Appears without a verifiable company identity
• Recommends full replacement without inspection
• Provides no written specification
• Cannot explain the roof build-up
• Claims every job has a guarantee but supplies no terms
• Uses another company’s accreditation
• Refuses to show insurance
• Pressures immediate work after an unsolicited visit
• Cannot explain Building Regulations
• Charges variations without written approval
• Leaves waste or scaffold responsibility unclear

Frequently asked questions

How many quotations should I obtain?

Three written quotations are usually enough, provided each contractor inspected the same roof and quoted for a comparable specification.

Is the cheapest quote best?

Not necessarily. It may omit scaffold, insulation, deck replacement, VAT or certification.

Does a new roof need Building Control approval?

Often, particularly where a substantial roof area or thermal element is replaced. Confirm with Building Control or a competent-person contractor.

Is a 20-year guarantee always insurance-backed?

No. A contractor’s workmanship guarantee and an insurance-backed guarantee are different documents.

Can a leak always be repaired?

Many can, but widespread deterioration, failed detailing or unsafe structure may justify replacement. The reason should be explained.

How long should a roof last?

It depends on material, design, exposure, workmanship and maintenance. Avoid universal lifespan guarantees.

Can roofing continue in rain?

Some work can proceed in light conditions, but roofs must be protected from water ingress and many systems require dry application conditions.
