VELUX

Short answer — the UK roofing brands people actually use

If you mean domestic roof replacements/repairs, don’t start with a national “roofing company” brand. Start with a good local NFRC/CompetentRoofer contractor and specify proven UK products. NFRC says its contractor members are vetted, inspected, and must meet its Code of Practice; for re-roofing, CompetentRoofer/NFRC CPS contractors can self-certify replacement roof coverings for Building Regulations purposes. (nfrc.co.uk)

Best “roofing companies” in the UK — depending on what you mean

1. For homeowners: use a vetted local roofer, not a national giant

For a house roof, the “best company” is usually a local specialist with the right trade registration, local references, scaffolding plan, insurance, and experience with your roof type. Ask for:

• NFRC membership or CompetentRoofer/NFRC CPS registration.
• Written quote with scaffold, waste, breathable membrane, battens, ventilation, dry ridge/verge, leadwork, insulation/building control all itemised.
• Product names, not vague “concrete tiles” or “felt”.
• Photos of recent jobs in your area.
• A clear guarantee: workmanship + manufacturer product/system warranty.
• Building Control certificate where required. GOV.UK lists replacement of roof coverings on pitched and flat roofs under work that can be handled via authorised competent person schemes such as CompetentRoofer or NAPIT. (gov.uk)

2. For big commercial projects: the UK’s major roofing/envelope contractors

If you mean large commercial roofing/cladding contractors, Roofing Today’s 2025 Top 40 ranked the biggest by turnover. The top names included CA Group, A&E Elkins, Lindner Prater, Hugh LS McConnell, FK Facades, Hathaway Roofing, MAC Roofing & Contracting, NRA Roofing & Flooring Services, Deane Roofing & Cladding, Cavello Group/Langley, and BriggsAmasco. CA Group was ranked number one for the third consecutive year. (roofingtoday.co.uk)

NFRC’s 2025 UK Roofing Awards also highlight high-quality specialists by trade: Lindner Prater won Project of the Year and sheeting/cladding, M. Camilleri & Sons Roofing won roof slating, Complete Waterproofing Services won roof tiling, Mariner Projects won single ply, Central Group won cold-applied liquid waterproofing, Claude N Smith won heritage, and EWN Leadwork Specialists won leadwork. (nfrc.co.uk)

Product recommendations by roof type

A) Most UK houses: concrete interlocking tiles

Best practical choices:

• Marley Modern — very common flat concrete interlocking tile.
• Marley Mendip — common profiled/double-roll type.
• Marley Edgemere / Edgemere 2.0 — good slate-effect concrete option; Marley describes Edgemere as one of the UK’s most popular concrete roof tiles, and Edgemere 2.0 uses carbon-capture cement technology. (marley.co.uk)
• BMI Redland Regent / 49 / Grovebury / Cambrian — widely specified mainstream alternatives. BMI’s UK portfolio covers Redland pitched roofing, Icopal flat roofing and Klober accessories. (bmigroup.com)
• Sandtoft/Wienerberger Calderdale, Double Roman, 20/20 — strong mainstream housebuilder/refurbishment options; Sandtoft 20/20 is an interlocking clay tile with a low minimum pitch option. (wienerberger.co.uk)
• Russell Roof Tiles Highland / Lothian / Grampian — widely used concrete tile options, especially for housing developments and regional projects. Russell states it manufactures concrete roof tiles and fittings. (russellrooftiles.com)

My pick for a normal UK re-roof: Marley Modern/Mendip or BMI Redland/Sandtoft equivalent, chosen to match the existing roof, pitch, planning context and neighbouring properties.

---

B) Period, conservation or premium roofs: natural slate

Best premium choice: Welsh Slate Penrhyn or Cwt-y-Bugail. Welsh Slate owns and operates Penrhyn, Ffestiniog and Cwt-y-Bugail quarries in North Wales and positions these as premium roofing slates. (welshslate.com)

Best commonly specified imported slate: CUPA PIZARRAS, especially CUPA 12 and CUPA 9. CUPA says one in two natural slates worldwide carries its brand, and CUPA 9 notes that rectangular format is the most common model in the UK. (cupapizarras.com)

My pick:

• Listed/conservation/high-end: Welsh Slate if budget allows.
• Good-quality everyday natural slate: CUPA 12 or CUPA 9 via a reputable merchant.

---

C) Slate look without slate cost: fibre cement slates

Look at Cedral/Etex and Swisspearl. Cedral promotes fibre-cement slates as uniform, strong and suited to volatile weather; Swisspearl’s UK range includes Jutland, Moorland and Westerland slates. (etexfibrecement.com)

My pick: Cedral or Swisspearl for extensions, garages, new-builds and budget-conscious projects where natural slate is too expensive.

---

D) Flat roofs: felt, single-ply, liquid or hot-melt

For UK flat roofs, the better brands are generally system manufacturers, not loose rolls bought cheaply online.

Strong choices:

• Bauder — very strong for commercial/specification flat roofs, green roofs and solar; product range includes reinforced bitumen membranes, single-ply, insulation, green/blue roof components and solar PV. (bauder.co.uk)
• IKO — major UK flat roofing name; IKO says it offers a full range of flat roof systems and pitched roofing products. (ikogroup.co.uk)
• BMI Icopal — long-established bituminous waterproofing and roofing systems under BMI. (bmigroup.com)
• Sika — especially Sarnafil single-ply, SikaShield bituminous membranes and Decothane liquid systems. (gbr.sika.com)
• Soprema, Alumasc, Langley, Radmat, Polyroof — common specification-grade options, particularly on commercial and public-sector roofs; these appear among key flat roof membrane suppliers in Barbour ABI’s UK market report. (store.barbour-abi.com)

My pick for a domestic extension flat roof: IKO/Bauder/Sika system installed by an approved contractor. For a cheap garage roof, EPDM can be fine, but on a warm roof over living space I’d favour a properly specified felt, single-ply or liquid system with insulation and detailing done by a specialist.

---

E) Roof windows and skylights

VELUX is the default brand most UK homeowners recognise. VELUX offers flashing kits for different roof coverings, including profiled tiles, slates, plain tiles, standing seam metal and conservation windows. (velux.co.uk)

Keylite and FAKRO are credible alternatives. Keylite sells roof windows, flashings, light tubes and loft ladders with product guarantees; FAKRO says it is one of the world’s leading roof window manufacturers and has operated in the UK market for 25 years. (keyliteroofwindows.com)

My pick: VELUX unless your builder/roofer has a strong reason to use Keylite or FAKRO.

---

F) Solar integrated into the roof

If you’re already re-roofing, integrated solar can look cleaner than on-roof rails and can save some roof covering area.

Best-known UK choices:

• Marley SolarTile — roof-integrated solar panel system that acts as roof covering and PV generation; Marley’s current range includes a 445Wp panel and a 335Wp panel, with BBA certification for the 445Wp range. (marley.co.uk)
• Viridian Clearline Fusion — UK-based roof-integrated solar system; Viridian describes itself as a UK-based manufacturer and launched Clearline Fusion in 2015. (viridian.solar)

My pick: Marley SolarTile/Viridian Clearline Fusion when doing a full roof replacement or new-build roof. For a simple retrofit on a sound existing roof, conventional on-roof panels may be cheaper.

---

Where UK roofers actually buy materials

For availability and matching old tiles, check specialist roofing merchants. SIG Roofing and Burton Roofing Merchants are two of the big names. Barbour ABI identifies SIG as the largest roofing merchant in UK roofing distribution, while Burton says it works with major brands including CUPA Pizarras, Marley, VELUX and Sandtoft. (amaresearch.co.uk)

---

My practical top 10 shortlist

If I were specifying a normal UK roof today, I’d shortlist:

1. Marley — best all-rounder for UK pitched roofs.
2. BMI Redland / BMI Icopal — strong pitched + flat roof coverage.
3. Wienerberger / Sandtoft — excellent clay and concrete tile range.
4. Russell Roof Tiles — solid concrete tile manufacturer.
5. Welsh Slate — premium natural slate.
6. CUPA PIZARRAS — widely used natural slate.
7. Cedral/Etex or Swisspearl — fibre-cement slate alternatives.
8. Bauder / IKO / Sika — top-tier flat roof systems.
9. VELUX — roof windows.
10. Marley SolarTile / Viridian Clearline Fusion — integrated solar roofing.

Final advice: choose the roofer first, but make them quote named products. A good quote should say something like: “Marley Modern smooth grey tiles, treated BS 5534 battens, breathable membrane, dry ridge, dry verge, Klober/BMI/Marley ventilation system, new leadwork, scaffold, waste, Building Control/CompetentRoofer certificate.” That’s far better than “new roof — £X”.

In the UK, when you are looking for the "best roofing companies," the answer depends on whether you are looking for high-quality roofing products and materials (the brands that architects, specifiers, and roofers actually trust), national commercial contractors, or vetted residential installers to work on your home.

The UK roofing market is highly localized for domestic properties, but it relies on a handful of massive, highly respected manufacturers and suppliers.

1. Top Roofing Material Brands (The Products People Actually Use)

If you are planning a roof replacement (re-roof) or extension, these are the market-leading brands that builders and professional roofers rely on:

For Pitched Roofs (Tiles & Slates)

• Marley: Historically one of the biggest names in UK roofing. They make everything from concrete tiles (the popular Modern and Ludlow Plus ranges) to clay tiles, timber shingles, and fibre-cement slates. They also offer Marley SolarTile, an increasingly popular integrated solar roof system used to meet Part L building regulations.
• Redland (BMI Group): Redland is a titan of the UK market, now part of the global BMI Group. Known for concrete interlocking tiles (like Double Roman and Regent) and traditional Rosemary clay plain tiles.
• Sandtoft (Wienerberger): Sandtoft is Wienerberger’s primary UK roof tile brand. They are highly regarded for clay tiles (like the Tempest and Olympus ranges) as well as cost-effective concrete tiles.
• Cupa Pizarras: If you are opting for a traditional slate roof, Cupa Pizarras is the premier brand for natural Spanish slate, which is heavily used across UK heritage and high-end residential projects.
• Dreadnought Tiles: Renowned for manufacturing beautiful, traditional Staffordshire blue clay tiles, widely specified for conservation areas and traditional UK homes.

For Flat Roofs & Membranes

• Sika (Sarnafil & Liquid Plastics): The gold standard for single-ply flat roofing in the UK. If you have an extension or garage, a Sika Sarnafil PVC membrane is highly durable, premium, and must be installed by a Sika-certified contractor.
• Bauder: The leading manufacturer of high-performance flat roof systems for commercial and premium residential properties. They specialize in bituminous membranes, single-ply, green roofs, and solar flat roofs.
• IKO (formerly Ruberoid): A household name in the UK trade for flat roof felt, high-performance bituminous membranes, and roof underlayment/breathable membranes.
• Elevate (formerly Firestone) EPDM: The go-to single-ply rubber roofing membrane for DIYers and residential roofers alike. It's incredibly long-lasting, seamless, and ideal for residential extensions.

Roof Windows

• Velux: The undisputed market leader for roof windows and skylights in loft conversions and extensions across the UK.

2. How to Find the Best Residential Roofing Contractors

Because the residential roofing sector is highly localized, there is no single "national" domestic roofing company that services every home in the UK. Instead, you should choose a local contractor who is registered with the industry's official bodies to avoid "cowboy builders".

To find a reputable local roofing company, look for these credentials:

• NFRC (National Federation of Roofing Contractors): The NFRC is the UK’s largest and most influential roofing trade association. Members undergo strict vetting, site inspections, and must hold correct insurance and technical standards. Hiring an NFRC member gives you access to a robust dispute resolution service if anything goes wrong.
• NFRC Competent Person Scheme (formerly CompetentRoofer): In England and Wales, if you are replacing 50% or more of your roof, it is a legal requirement to notify Local Authority Building Control (LABC) and upgrade insulation to meet building regulations. A contractor registered with the NFRC CPS can self-certify their own work, meaning you don't have to pay for a local council building inspector to sign it off.
• TrustMark: A Government-endorsed quality scheme that vets tradespeople for customer service, technical competence, and trading practices.
• Federation of Master Builders (FMB): While not roofing-specific, many of the best roofing companies are also FMB members.

---

3. Top National Commercial & Industrial Roofing Contractors

If you are looking for a company to handle a massive commercial, industrial, or multi-property project (such as warehouses, retail parks, or large-scale housing developments), the major national players are:

• Briggs Amasco: One of the UK's longest-established and most respected commercial roofing contractors, operating out of a national network of branches.
• Nationwide Industrial Roofing: Widely ranked as the top specialist industrial contractor for large-scale roof replacements, over-roofing, and cladding on warehouses, factories, and logistics hubs.
• Central Group (Central Roofing): A major B2B contractor with a nationwide branch network specializing in refurbishment and commercial maintenance.
• Note on Avonside Group: Formerly the UK's largest residential new-build roofing contractor, Avonside went into administration in late 2022. While some localized branches were bought out and still operate, they no longer exist as the singular nationwide giant they once were.

---

4. Where the Trade Buys (The Top Roofing Merchants)

If you are managing a project yourself or buying materials directly, you will want to skip general DIY stores (like B&Q or Wickes) and buy from specialist roofing merchants, where you can get trade-quality products:

• SIG Roofing: The UK's largest specialist distributor of roofing materials, with over 100 branches nationwide. They stock everything from Marley tiles to flat roof systems and lead.
• Burton Roofing Merchants: The UK's leading independent specialist merchant, known for excellent stock levels of slate, clay, concrete tiles, and flat roofing products.
• Roofbase: A rapidly growing specialist roofing merchant with excellent technical support for both the trade and self-builders.
• Travis Perkins / Jewson: While these are general builders' merchants, they both have dedicated national roofing divisions and can source almost any manufacturer's product.

The "best" roofing companies and products in the UK depend on your location, whether you need pitched or flat roofing, the scale of the job (domestic repairs vs. larger projects), budget, and priorities like longevity or aesthetics. Always get multiple quotes from NFRC (National Federation of Roofing Contractors) members or TrustMark-accredited firms, check recent Checkatrade or Google reviews, and ensure insurance-backed guarantees (often 10+ years). Local specialists often deliver the best value for homeowners, while larger contractors handle bigger or commercial work.

Top Large-Scale Roofing Contractors

These rank highly by turnover and industry recognition (e.g., Roofing Today Top 40 lists):

• CA Group — Frequently tops the charts (No. 1 for multiple years running) for building envelope and cladding work.
• A & E Elkins — Strong performer, climbing rankings with significant growth; London and South East focus.
• Hugh LS McConnell (Ayrshire-headquartered) — Rapidly rising (e.g., to 4th place); known for strong order books and contracts.
• Other notables from industry awards (NFRC UK Roofing Awards): MAC Roofing & Contracting, Inspire Contract Services (often with Bauder), Alpha Specialist Roofing, Fenland Flat Roofing, and Central Group.

These suit larger or specialist projects; for everyday domestic work, they're less common.

Highly Rated Local/Consumer Roofers

Checkatrade and similar platforms highlight excellent customer-rated firms (many with 9.8–10/10 scores from hundreds of reviews):

• Examples include Roberts Roofing (North Cheam/London area, exceptional feedback on quality and communication), All Roofing (Swindon, strong on repairs and flat roofs), Walker Roofing Ltd (Worthing/Sussex), and others like Toproofers Ltd or regional specialists.
• Search Checkatrade by postcode for current top-rated options near you—many offer free quotes and guarantees.

NFRC award winners (e.g., for specific techniques like liquid waterproofing or heritage work) also indicate skilled installers.

Popular Roofing Materials and Brands People Actually Use

UK homeowners and contractors commonly choose based on durability, cost, and climate suitability (wet, windy conditions).

Pitched roofs (most common for homes):

• Natural slate (Welsh or Spanish) — Longevity champion (80–150+ years); premium traditional look. Popular for period properties.
• Clay tiles (e.g., Marley, Redland, Sandtoft ranges) — 60–80+ years; excellent colour retention and aesthetics.
• Concrete tiles (e.g., Marley Modern, Redland Cambrian) — Best value for many (40–60 years); affordable, robust, and widely used.

Flat roofs (extensions, garages, etc.):

• EPDM rubber — Most reliable all-rounder for domestic use (30–50 years); flexible, low maintenance, and forgiving.
• GRP fibreglass — Seamless, rigid finish popular for visible smaller areas.
• Systems from brands like Bauder, Sika, Radmat, or IKO are frequently specified in award-winning projects.

Roof windows/skylights:

• Velux — The dominant, most trusted brand (widely installed, reliable range); alternatives like Fakro or Keylite for value.

Other mentions: SIG Roofing for distribution/supply, and insulation like Kingspan or Celotex for energy efficiency compliance.

Quick tips for UK homeowners:

• Prioritise pitched slate or clay for heritage/value retention; concrete or EPDM for budgets.
• Factor in scaffolding, stripping old materials, and Building Regulations (e.g., insulation standards).
• Get 3+ quotes, verify accreditations, and ask about warranties.
• For solar integration or green roofs, specialists in those areas (sometimes overlapping with the above) are worth seeking.

If you share your location, roof type, or specific needs (e.g., repair vs. full replacement), I can help refine suggestions further!

The best options for a roofing project in the United Kingdom depend entirely on whether you are looking for trusted product manufacturers or major national commercial contractors.

The top brands, products, and national contractors that dominate the UK roofing industry include the following options:

Domestic Roofing Note

For residential domestic roofing (replacing a standard house roof), homeowners do not hire massive national commercial entities like BriggsAmasco or CA Group. Instead, you should source trusted regional independent contractors who are fully accredited members of the National Federation of Roofing Contractors (NFRC) or verified via the CompetentRoofer scheme. This guarantees they can self-certify their work for local Building Regulations compliance.

If you are looking to source materials or hire someone for a specific project, let me know:

Is your project residential or commercial? Are you dealing with a pitched roof (tiles/slate) or a flat roof (extension/garage)? Do you need product supply recommendations or are you looking to find an installer?
