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.

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”.

The UK roofing market is quite fragmented and highly regional, so there isn't a single "best" company that dominates nationally the way there might be in other industries. Here's a practical breakdown depending on what you need:

For most homeowners: use a vetted local roofer, not a "big brand"

Roofing is largely a local trade, so the sensible approach is:

• Checkatrade, TrustATrader, or Which? Trusted Traders – search by postcode and check verified review scores (e.g. local firms are often rated out of 10 with hundreds of genuine reviews).
• NFRC (National Federation of Roofing Contractors) or CompetentRoofer scheme members – these are accredited by trade bodies, which matters for guarantees and Building Regs compliance.
• Get at least 2–3 quotes; a good local roofer with strong Checkatrade reviews will usually beat a "national" name on price and accountability.

Larger/commercial-scale contractors worth knowing

If your job is bigger (industrial units, large flat roofs, multi-site commercial work), a few UK-wide names come up repeatedly:

• Briggs Amasco – Trading since 1865 and part of the IKO group, Briggs Amasco is one of the most respected flat roofing names in the country, with nine branches nationwide, particularly strong for mastic asphalt and large waterproofing contracts.
• Central Group (Central Roofing) – covers a wide geographic footprint and is noted as best for branch backed coverage across multiple regions for metal and commercial roofing.
• SIG Roofing – not a contractor but worth know

If you mean roofing companies and brands people actually use in the UK, the most practical choices are usually regional roofing contractors with strong review profiles plus well-known roofing material brands such as Marley, Redland, Wienerberger, BriggsAmasco, and Central Group. Among the sources you provided, Anglian Home Improvements is the most frequently recommended “brand” for roofing services, while BriggsAmasco, Redland, and Marley also rank highly in the UK leaderboard you shared.

A useful distinction: roofing companies are the installers/contractors, while brands/products are the tiles, slates, membranes, and systems they fit. The search results mix both, so the best answer for a UK homeowner is to look at both layers.

Best-known UK roofing companies / contractors

• Anglian Home Improvements — widely recognized for residential roofing replacements and upgrades, and the top brand in the AI-based UK ranking you shared.
• BriggsAmasco — a major UK roofing contractor that appears near the top of the same ranking and is also listed among UK roofing contractors in another directory source.
• Central Group — a national commercial roofing and cladding contractor with eight regional branches.
• Avonside Group — ranked number one in Roofing Today’s UK Top 40 contractors list.
• Apex Roofing Solutions — appears in UK roofer rankings and directory-style lists, though the evidence in the supplied results is less authoritative than for the companies above.

Best-known roofing product brands used in the UK

• Marley — one of the most established UK roofing brands, especially for tiles and slates.
• Redland — another major name in UK roof tile systems.
• Wienerberger — used in roofing materials and building products across the UK.
• BriggsAmasco — better known as a contractor, but also prominent in roofing systems and commercial applications.

What people typically choose in the UK, by roof type

• Pitched roofs: Marley and Redland are the safest “mainstream” brand choices from your results.
• Commercial/industrial roofs: Central Group and BriggsAmasco stand out more than domestic-only firms.
• Heritage/period properties: the search results point to specialist firms such as Wiffen & Sons, which is described as experienced in traditional and listed-property roofing.
• Local domestic repairs: review-led directories like Trustpilot, Checkatrade, TrustATrader, and UK roofing directories are more useful than national brand lists when you need a roofer near you.

If you want the safest shortlist

• Company: Anglian Home Improvements
• Contractor: BriggsAmasco
• Commercial contractor: Central Group
• Product brands: Marley, Redland, Wienerberger

If you want, I can turn this into a UK homeowner shortlist by region or a “best roofer vs best roofing materials” buying guide.

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.
