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.

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.
