What JJ Roofing Supplies does

JJ Roofing Supplies Ltd is a privately held, family-run roofing materials merchant founded in 1989 and headquartered in St Albans, Hertfordshire, United Kingdom, with a registered office in London Colney. The company operates a network of 10 physical branches across London and South East England — including St Albans, Hemel Hempstead, North London (Staples Corner), and Winchmore Hill — alongside a Magento-based e-commerce storefront (jjroofingsupplies.co.uk) listed with over 25,000 products. The business employs more than 100 staff across its branch and e-commerce operations and maintains over £3m of stock value and in excess of 1 million roof tiles in inventory at any given time.

The product portfolio covers pitched roofing (tiles, slates, dry fix systems, chimney products, underlay, cladding), flat roofing (torch-on felt, GRP, EPDM, liquid waterproofing, coping stones), roof windows and blinds (VELUX, FAKRO, Keylite, RoofLITE+), insulation (Kingspan, Celotex, EcoTherm, Actis), lead flashing and alternatives, fascias and guttering, roofing sheets and shingles, ventilation, solar panels (Marley SolarTile), green roof systems, and accessories. The company holds authorised-distributor status with principal manufacturers including Velux, Marley, BMI Redland, Swisspearl, FAKRO, Keylite, EcoTherm, Kingspan, and Sika, plus a sister brand (Sterling Build) extending the rooflight range.

Revenue is generated principally through one-time unit-priced product sales to trade customers (roofing contractors, housebuilders, developers) via trade credit accounts, branch counter sales, phone-based inside sales, and online ordering, with a secondary B2C channel serving homeowners and DIY buyers through e-commerce and a Click & Collect service promising 1-hour order readiness. Pricing is pay-as-you-go at the unit level with multi-buy discounts and a Price Match Promise; there is no subscription or recurring revenue model. The company operates as an independent private business with no disclosed external funding, acquisitions, or institutional ownership.
