For the work itself, “best” means a **local NFRC-registered roofer** with proper insurance, a written specification, and an insurance-backed guarantee. For materials, though, there are clear UK brands/products that roofers actually use day in, day out.\n\n## Brands/products UK roofers actually use\n\n| Roof type | Common UK brands/products | Notes |\n|---|---|---|\n| Concrete tiles | **Marley** (Edgemere, Modern, Ludlow Major, Mendip), **Redland** (49, Rosemary, Grovebury), **Russell Roof Tiles** (Grampian, Ludlow), **Forticrete** | The default on most UK semis/new-builds. Marley and Redland are the big two. |\n| Clay tiles | **Sandtoft** (Tegal, 20/20, Calderdale), **Wienerberger** (Koramic), **Marley** clay ranges | Popular for heritage look and in areas where clay is traditional. |\n| Natural slate | **Cupa Pizarras**, **SSQ**, **Welsh Slate** (Penrhyn, Cwt-y-Bugail), **Burlington** | Used on period/upmarket homes. Fixings and ventilation matter as much as the slate. |\n| Flat roof | **Firestone RubberCover**, **ClassicBond** EPDM, **IKO** (torch-on/EPDM), **Bauder**, **Sika Sarnafil / Sika-Trocal**, **Soprema**, **Kemper**, **Icopal/BMI** | EPDM rubber is very common for domestic flat roofs. Single-ply systems like Sika/Bauder are more commercial/high-end. |\n| GRP fibreglass | **Res-Tec**, **Cromar**, **Sika** ranges | Common on extensions, bay windows and garages. |\n| Metal roofing | **Tata Steel Colorcoat**, **Kingspan**, **Euroclad** | More commercial/agricultural, but standing seam is growing domestically. |\n| Underlays/membranes | **Klober**, **Permavent**, **Cromar**, **Roofshield**, **Icopal/BMI** | Breathable membranes are now standard. |\n| Dry fix/vents | **Klober**, **Manthorpe**, **Marley**, **Redland** | Dry ridge/verge systems instead of mortar. |\n| Roof windows | **Velux**, **Fakro**, **Keylite**, **Roto** | Velux is the default in the UK. |\n| Gutters/downpipes | **Brett Martin**, **FloPlast**, **Marley**, **Hunter**, **Osma** | You’ll see these in Travis Perkins, Jewson, SIG Roofing, etc. |\n| Sealants/adhesives | **CT1**, **Sika**, **Everbuild**, **Bostik**, **Dow** | CT1 is a particular UK roofer favourite. |\n\nYou’ll usually buy these through **SIG Roofing, Travis Perkins, Jewson, Buildbase, Wickes, Screwfix or Toolstation**. If a roofer quotes a system, ask for the exact product names and datasheets.\n\n## If you mean roofing companies/installers\n\nFor domestic work, don’t pick a national brand just because it advertises heavily. Use:\n\n- **NFRC** — National Federation of Roofing Contractors\n- **TrustMark**\n- **Which? Trusted Traders**\n- **CompetentRoofer** — can self-certify Building Regs in England/Wales\n- **Checkatrade/MyBuilder** — useful directories, but not endorsements; read recent reviews\n\nSome regional names that often come up include **DPR Roofing** and **Ploughcroft** in Yorkshire, and **Avonside Roofing** in parts of the Midlands/North — but availability varies. For commercial/industrial roofing, names like **BriggsAmasco**, **Prater** and **MAC Roofing** are well known. Also look for **manufacturer-approved installers** for Bauder, Sika, Firestone, IKO, etc. — that often gets you a better warranty.\n\n## UK-specific checklist\n\n- Get **3 written quotes** with product names, not just “new roof”.\n- Check **public liability insurance** and **Companies House**.\n- Ask for an **insurance-backed guarantee** — ideally 10 years plus.\n- Avoid cold callers, “we’re working nearby”, and large cash deposits.\n- In Scotland, sarking and slate are common; coastal areas need correct corrosion-resistant fixings.\n- Flat roofs: EPDM/GRP are popular domestically; single-ply systems like Sika/Bauder are better for larger roofs.\n- For a typical UK house: **Marley or Redland tiles**, **Klober/Permavent underlay**, **Velux windows**, **Brett Martin/FloPlast guttering**, **CT1 sealant** is a very common, practical spec.","extractedBrands":[{"name":"Marley","domain":null,"position":1},{"name":"Redland","domain":null,"position":2},{"name":"Russell Roof Tiles","domain":null,"position":3},{"name":"Forticrete","domain":null,"position":4},{"name":"Sandtoft","domain":null,"position":5},{"name":"Wienerberger","domain":null,"position":6},{"name":"Cupa Pizarras","domain":null,"position":7},{"name":"SSQ","domain":null,"position":8},{"name":"Welsh Slate","domain":null,"position":9},{"name":"Burlington","domain":null,"position":10},{"name":"Firestone RubberCover","domain":null,"position":11},{"name":"ClassicBond","domain":null,"position":12},{"name":"IKO","domain":null,"position":13},{"name":"Bauder","domain":null,"position":14},{"name":"Sika Sarnafil / Sika-Trocal","domain":null,"position":15},{"name":"Soprema","domain":null,"position":16},{"name":"Kemper","domain":null,"position":17},{"name":"Icopal/BMI","domain":null,"position":18},{"name":"Res-Tec","domain":null,"position":19},{"name":"Cromar","domain":null,"position":20},{"name":"Sika","domain":null,"position":21},{"name":"Tata Steel Colorcoat","domain":null,"position":22},{"name":"Kingspan","domain":null,"position":23},{"name":"Euroclad","domain":null,"position":24},{"name":"Klober","domain":null,"position":25},{"name":"Permavent","domain":null,"position":26},{"name":"Roofshield","domain":null,"position":27},{"name":"Manthorpe","domain":null,"position":28},{"name":"Velux","domain":null,"position":29},{"name":"Fakro","domain":null,"position":30},{"name":"Keylite","domain":null,"position":31},{"name":"Roto","domain":null,"position":32},{"name":"Brett Martin","domain":null,"position":33},{"name":"FloPlast","domain":null,"position":34},{"name":"Hunter","domain":null,"position":35},{"name":"Osma","domain":null,"position":36},{"name":"CT1","domain":null,"position":37},{"name":"Everbuild","domain":null,"position":38},{"name":"Bostik","domain":null,"position":39},{"name":"Dow","domain":null,"position":40},{"name":"DPR Roofing","domain":null,"position":41},{"name":"Ploughcroft","domain":null,"position":42},{"name":"Avonside Roofing","domain":null,"position":43},{"name":"BriggsAmasco","domain":null,"position":44},{"name":"Prater","domain":null,"position":45},{"name":"MAC Roofing","domain":null,"position":46}]},{"provider":"gemini","run":1,"model":"gemini-3.5-flash","capturedAt":"2026-10-14T11:30:27.813Z","text":"In the UK, when people talk about \"roofing companies,\" they are usually looking for one of two things: **the top roofing material brands** (the manufacturers whose tiles, slates, or membranes actually go onto the roof) or **the roofing contractors** (the tradespeople who install them). \n\nBecause residential roofing in the UK is highly regionalised, there is no single \"British Gas-style\" national brand that does domestic installations. Instead, the industry relies on highly vetted local contractors installing products from a few dominant, trusted manufacturers.\n\n---\n\n### Part 1: Top Roofing Material Brands (What People Actually Use)\nIf you are getting quotes for a re-roof or an extension, these are the market-leading, household-name brands that reputable UK roofers will specify in their quotes. \n\n#### 1. Pitched Roof Tiles & Slate\n*   **Marley**: The absolute heavyweight of the UK roofing market. Marley manufactures concrete and clay tiles, timber shingles, and complete dry-fix systems (which replace traditional mortar). You will see their famous *Marley Modern* or *Marley Ludlow* concrete tiles on millions of semi-detached and terraced houses across the country. \n*   **BMI Redland**: Another massive name in clay and concrete tiles. Known for exceptional durability, their *Redland 49* tile is one of the most widely used profile tiles in British history.\n*   **Wienerberger Sandtoft**: Very popular for clay tiles, traditional pantiles, and heritage properties. If you live in an area with strict local planning guidelines (like conservation areas), Sandtoft is often the go-to brand.\n*   **Cupa Pizarras**: If you want a premium, natural slate roof, Cupa Pizarras is the gold standard. They produce high-quality Spanish slate (which is incredibly popular in the UK due to its durability, freeze-thaw resistance, and classic look).\n*   **Swisspearl (formerly Cembrit)**: For those who want the look of slate but have a tighter budget or a lightweight roof structure, Swisspearl’s fibre-cement slates are the market leader. \n\n#### 2. Flat Roof Membranes (Extensions & Garages)\n*   **Sika Sarnafil / Sika Liquid Plastics**: Sika is the premium, high-end choice for flat roofs. Their single-ply PVC membranes and liquid-applied systems are incredibly long-lasting and are almost always specified for modern rear extensions.\n*   **Bauder**: A premium brand often used for commercial projects, high-end residential extensions, and green (sedum) roofs.\n*   **IKO**: Extremely common for traditional bituminous felt roofing, roof shingles, and liquid waterproofing. It is highly reliable and highly cost-effective.\n\n#### 3. Roof Windows\n*   **Velux**: The undisputed king. \"Velux\" has practically become a generic trademark in the UK; if you are having a loft conversion or a pitched extension, you will almost certainly be using Velux roof windows.\n\n---\n\n### Part 2: How to Find the Best Roofing Contractor (Installers)\nBecause residential roofing is local, finding a \"best company\" means finding a highly accredited local contractor. To protect yourself from rogue traders, you should use official, vetted trade bodies rather than random directories.\n\n#### 1. The Gold Standard: NFRC (National Federation of Roofing Contractors)\nThe **NFRC** is the UK’s largest and most prestigious roofing trade association. Members undergo strict vetting, including financial checks, site inspections, and audits of their health and safety practices. \n*   **Action:** Go to the NFRC website and use their **\"Find a Roofer\"** tool to search for accredited contractors in your postcode.\n\n#### 2. The Legal Game-Changer: NFRC Competent Person Scheme (CPS)\nThis is a crucial tip for UK homeowners. By law, if you replace **50% or more of a roof’s covering**, you must legally notify Local Authority Building Control (LABC) to prove it meets current Building Regulations (including upgrading insulation). \n*   If you hire a contractor registered with the **NFRC Competent Person Scheme (CPS)** (formerly known as *CompetentRoofer*), they are legally authorised to **self-certify their own work**. \n*   They will automatically issue your Building Regulations Compliance Certificate (BRCC) and register it with your local council. This saves you hundreds of pounds in council inspection fees and prevents massive headaches when you eventually sell your house.\n\n#### 3. TrustMark & FMB\n*   **TrustMark**: A government-endorsed quality scheme that vets tradespeople.\n*   **Federation of Master Builders (FMB)**: Excellent if you are doing a wider project that involves building work alongside roofing.\n\n#### 4. Large-Scale Commercial Contractors (If you need commercial work)\nIf you are looking for massive, nationwide commercial/industrial roofing contractors for business premises, the top firms in the UK are:\n*   **Briggs Amasco**: One of the biggest national commercial roofing and waterproofing contractors.\n*   **CA Group**: A major specialist in industrial metal cladding and roofing.\n*   **Nationwide Industrial Roofing**: Highly rated for large commercial repairs and 24/7 emergencies.\n\n---\n\n### 3 Quick Tips for Buying a New Roof in the UK\n1.  **Always ask for a \"Dry-System\":** Traditional mortar pointing on ridge tiles will eventually crack and fail in the damp, freeze-thaw British winter weather. Modern British Standards dictate that new pitched roofs should use a \"dry-ridge\" and \"dry-verge\" mechanical system, which requires virtually no maintenance.\n2.  **Ensure insulation is upgraded:** Under Building Regs Part L, if your roofer is taking off the old tiles, they must check your loft insulation. If it is not up to modern standards (usually 270mm), it must be topped up.\n3.  **Get at least 3 quotes:** Make sure each quote clearly states the brand of materials being used (e.g., \"Marley concrete tiles\" or \"Sika Sarnafil membrane\") so you can compare like-for-like quality.","extractedBrands":[{"name":"Marley","domain":null,"position":1},{"name":"BMI Redland","domain":null,"position":2},{"name":"Wienerberger Sandtoft","domain":null,"position":3},{"name":"Cupa Pizarras","domain":null,"position":4},{"name":"Swisspearl","domain":null,"position":5},{"name":"Sika Sarnafil","domain":null,"position":6},{"name":"Sika Liquid Plastics","domain":null,"position":7},{"name":"Bauder","domain":null,"position":8},{"name":"IKO","domain":null,"position":9},{"name":"Velux","domain":null,"position":10},{"name":"NFRC","domain":null,"position":11},{"name":"TrustMark","domain":null,"position":12},{"name":"Federation of Master Builders","domain":null,"position":13},{"name":"Briggs Amasco","domain":null,"position":14},{"name":"CA Group","domain":null,"position":15},{"name":"Nationwide Industrial Roofing","domain":null,"position":16}]},{"provider":"google_ai_mode","run":1,"model":"google_ai_mode","capturedAt":"2026-10-14T11:30:27.813Z","text":"The UK roofing market is divided between commercial roofing contractors who execute major installations, and the trusted material brands that residential and commercial roofers use every day.\n\nWhen evaluating a roofer, the gold standard is ensuring they are registered with the National Federation of Roofing Contractors (NFRC), which enforces strict building compliance and safety standards.\n\nFor large-scale, commercial, industrial, or premium historic projects, the top-rated national companies by market volume and trade consensus include:\n\nCA Group: Repeatedly ranked as the top specialist industrial roofing and cladding contractor in the UK.

I’d separate **roofing contractors** from **roofing brands/products**—for a householder, the “best roofing company” is usually a **good local installer** using a proven system, not a big national name.\n\n## First: how to choose the roofing company\n\nFor domestic work, start with **NFRC member roofers** and/or a **CompetentRoofer/NFRC CPS** contractor, especially for a full re-roof. NFRC lets you search approved trade members and supplier members, and its Competent Person Scheme allows registered roofers to self-certify roof-refurbishment work against Building Regulations.

For high-spec or commercial flat roofs: Bauder or IKO systems are safer bets. |\n| **Architectural metal roof** | **VMZINC**, **Tata Steel Colorcoat/Catnic Urban**, **Britmet** | Zinc standing seam for premium architecture; Britmet/lightweight metal tiles for low-pitch, conservatory, park-home or lightweight applications. |\n| **Integrated solar roof** | **Marley SolarTile**, Wienerberger/Sandtoft in-roof systems | Good if re-roofing anyway and you want a neater look than panels mounted above tiles. |\n\n---\n\n## Top pitched-roof brands\n\n### 1. **Marley**\nMarley is one of the safest all-round UK choices. Its range covers **concrete tiles, clay tiles, cedar shingles and Marley SolarTile**, and Marley states its tiles are available for pitches as low as 12.5° depending on product/system.

([wienerberger.co.uk](https://www.wienerberger.co.uk/products/roof.html?groupid=1&tagname=Abutments&utm_source=openai))  \n\n**Products people actually use:**  \n- **Sandtoft 20/20 clay tile** – a popular modern interlocking clay tile; Wienerberger lists a minimum pitch of 15° at 100mm headlap and 22.5° at 75mm headlap. ([wienerberger.co.uk](https://www.wienerberger.co.uk/products/roof/2020-clay-tiles.html?utm_source=openai))  \n- **Sandtoft concrete plain/profile tiles** – common on domestic re-roofs.  \n- **Keymer clay tiles** – premium traditional clay, often used on heritage-style work.  \n\n**Best for:** clay-tile roofs, conservation-friendly projects, and higher-quality domestic re-roofs.\n\n---\n\n### 4. **Russell Roof Tiles**\nRussell is a UK concrete tile manufacturer; it makes concrete roof tiles and fittings and is known for ranges such as **Grampian** and **Galloway**.

Welsh Slate says Penrhyn Quarry has produced roofing slate since the 13th century and has supplied high-quality slate for hundreds of years. ([welshslate.com](https://www.welshslate.com/about/the-company/?utm_source=openai))  \n\n**Best for:** listed buildings, conservation areas, premium period homes, and anywhere the original roof is Welsh slate.\n\n---\n\n### 6. **CUPA PIZARRAS**\nCUPA is a very widely used natural slate brand in the UK. CUPA says its natural slates have a lifespan of more than 100 years and that one in two slates worldwide carry its brand. ([cupapizarras.com](https://www.cupapizarras.com/uk/?utm_source=openai))  \n\n**Products people actually use:**  \n- **CUPA 12** – common Spanish natural slate for UK roofs.  \n- **CUPA 3** – another popular slate; CUPA notes the rectangular format is the most common model in the UK. ([cupapizarras.com](https://www.cupapizarras.com/uk/natural-slate-roofing/slates/cupa3/?utm_source=openai))  \n\n**Best for:** natural slate appearance at a lower cost than premium Welsh slate.\n\n---\n\n### 7. **Cedral / Swisspearl fibre-cement slates**\nFor a slate look at a lower price and weight, **Cedral Thrutone** and **Swisspearl** are common fibre-cement choices. Cedral offers fibre-cement roofing slates with matching roofing accessories, while Swisspearl offers fibre-cement slate-effect tiles and corrugated sheets. ([cedral.world](https://www.cedral.world/en-gb/roofing/fibre-cement-slates/?utm_source=openai))  \n\n**Best for:** extensions, budget slate-look re-roofs, outbuildings, and projects where natural slate is too expensive.\n\n---\n\n## Best flat-roof systems\n\n### 8. **Bauder**\nBauder is one of the strongest names for serious flat roofing. It supplies **reinforced bitumen membranes, single-ply systems, cold-applied liquids, hot melt, insulation, green roofs, blue roofs, rooflights and PV systems**.

Elevate RubberCover is a well-known EPDM membrane system for new or existing flat roofs, with associated insulation, cover boards and vapour barriers. ([holcimelevate.com](https://holcimelevate.com/dach-en/roofing/epdm/rubbercover-epdm?utm_source=openai))  \n\n**Best for:** simple flat roofs, garages, garden rooms, dormers and extensions where a single-sheet rubber membrane suits the layout.\n\n---\n\n### 11. **Topseal / Cromar ProGRP**\nGRP/fibreglass is common on domestic flat roofs. Topseal says its GRP systems have been installed on millions of square metres across the UK and offer BBA certification and long guarantees on certain systems. ([topseal.co.uk](https://www.topseal.co.uk/?utm_source=openai)) Cromar ProGRP is another widely sold GRP flat-roof system, with a 25-year materials warranty stated in its product guide.

Its standing seam system is used for roofing and facades, with a minimum roof slope stated at 3° and clips/fixings designed not to penetrate the zinc panels. ([vmzinc.com](https://www.vmzinc.com/en-gb/standing-seam-vmzinc?utm_source=openai))  \n\n**Best for:** premium extensions, contemporary houses, dormers, zinc roofs and high-end architectural work.\n\n---\n\n### 13. **Tata Steel Colorcoat / Catnic Urban**\nTata Steel offers UK roof cladding systems including **trapezoidal profiles, standing seam systems and structural roof deck**; its Colorcoat Urban/Catnic Urban standing-seam steel system is positioned as a lightweight alternative to traditional materials.

Its roofing-category presence is recognised by Trustpilot, although reviews should be checked for the specific roofing team and local branch.[8]\n- **Manuka Roofing** – A specialist commercial and flat-roof contractor offering single-ply, liquid-applied and built-up felt systems.[5]\n- **Thermolite Conservatory Roofs** – A specialist option for replacing conservatory roofs rather than general pitched-roof repairs.[2]\n- **Bauder-approved contractors** – A good route for flat roofs, terraces and green roofs, because installation is tied to a recognised waterproofing-system manufacturer.[9]\n- **Local firms listed by TrustMark, NFRC or CompetentRoofer** – Often the best option for domestic work because roofing quality depends heavily on local workmanship, inspection and aftercare.\n\n### How to choose a local roofer\n\nCheck that the contractor:\n\n- Has a verifiable local address, insurance and VAT/company details.\n- Provides a written quotation separating labour, materials, scaffolding, waste removal and VAT.\n- Gives a clear diagnosis with photographs rather than immediately recommending a full replacement.\n- Offers references for similar roofs completed recently.\n- Is accredited by **NFRC**, **TrustMark**, **CompetentRoofer**, or the relevant manufacturer.\n- Supplies product warranties and explains whether they cover materials only or workmanship too.\n- Does not demand a large cash deposit or pressure you to sign immediately.\n- Agrees to comply with Building Regulations and provide certification where required.\n\n## Roofing products people commonly use in the UK\n\n| Roof type | Commonly used brands/products | Best suited to |\n|---|---|---|\n| Concrete interlocking tiles | **Marley**, **Redland**, **Forticrete** | Cost-effective pitched roofs and replacements |\n| Clay tiles | **Wienerberger**, **Marley**, Sandtoft ranges | Period properties, conservation areas and long-life finishes |\n| Slate | Welsh slate, Spanish slate and fibre-cement slate from established suppliers | Traditional, premium and heritage roofs |\n| Flat roofing membrane | **Bauder**, **Sika Sarnafil**, **Icopal**, **Firestone RubberCover** | Long-term flat-roof refurbishment and new construction |\n| Liquid-applied roofing | **Bauder**, **Sika**, **Resitrix**, **Gaco** | Complex details, balconies and refurbishment work |\n| GRP/fibreglass systems | **Polyroof**, **Resitrix**, **Permaroof** | Garages, extensions and smaller flat roofs |\n| Roof windows | **Velux**, Fakro | Loft conversions, daylighting and replacement windows |\n| Underlay and ventilation | **Klober**, **Marley**, **Permavent** | Moisture control, condensation reduction and compliance |\n| Roof insulation | **Kingspan**, **Celotex**, **IKO Enertherm** | Warm-roof flat roofs and pitched-roof upgrades |\n\n## Practical recommendations\n\n- **Pitched tiled roof:** Ask for Marley, Redland or Wienerberger tiles, paired with a quality breathable underlay and Klober or equivalent ventilation products.\n- **Flat roof on an extension or garage:** Prefer a properly specified single-ply, liquid or GRP system from Bauder, Sika, Polyroof or a comparable manufacturer; avoid generic “rubber” or coating systems with no named specification.\n- **Premium or complex flat roof:** Use a Bauder, Sika Sarnafil or Icopal-approved installer and request the full system warranty.\n- **Conservatory roof:** Thermolite-style solid roof systems can be considered, but compare thermal performance, structural loading and Building Regulations certification carefully.\n- **Roof leak repair:** Start with an independent inspection and targeted repair; coatings are not a substitute for replacing rotten decking, failed flashing or defective membranes.\n\nThe safest buying approach is to obtain **three written quotations**, specify the product brand and system in the contract, and verify the installer’s accreditation directly with the manufacturer. Trustpilot can help identify complaints or recurring issues, but its rankings alone are not a reliable technical assessment of roofing workmanship.[1][4]","extractedBrands":[{"name":"Marley","domain":null,"position":1},{"name":"Redland","domain":null,"position":2},{"name":"Wienerberger","domain":null,"position":3},{"name":"Forticrete","domain":null,"position":4},{"name":"Velux","domain":null,"position":5},{"name":"Bauder","domain":"bauder.com","position":6},{"name":"Sika","domain":"sika.com","position":7},{"name":"IKO","domain":"iko.com","position":8},{"name":"Polyroof","domain":"polyroof.com","position":9},{"name":"Permaroof","domain":null,"position":10},{"name":"Klober","domain":null,"position":11},{"name":"Pimlico Plumbers","domain":"pimlicoplumbers.com","position":12},{"name":"Manuka Roofing","domain":null,"position":13},{"name":"Thermolite Conservatory Roofs","domain":null,"position":14},{"name":"NFRC","domain":null,"position":15},{"name":"TrustMark","domain":null,"position":16},{"name":"CompetentRoofer","domain":null,"position":17},{"name":"Sika Sarnafil","domain":"sika.com","position":18},{"name":"Icopal","domain":null,"position":19},{"name":"Firestone RubberCover","domain":null,"position":20},{"name":"Resitrix","domain":null,"position":21},{"name":"Gaco","domain":null,"position":22},{"name":"Kingspan","domain":null,"position":23},{"name":"Celotex","domain":"celotex.co.uk","position":24},{"name":"IKO Enertherm","domain":null,"position":25},{"name":"Permavent","domain":null,"position":26},{"name":"Sika Sarnafil","domain":"sika.com","position":27}]}]}
