What Langley Waterproofing Systems does

Langley Waterproofing Systems is a UK-based specialist in flat and pitched roofing, waterproofing, and environmental roofscape solutions, operating as Langley UK Limited (registered in England and Wales, company number 06650838) from its headquarters in Daventry, Northamptonshire. The company has specialised in flat roofing membranes since the early 1960s and introduced the first SBS modified bituminous membrane system to the UK market in 1972, building more than six decades of category presence. Its core technology portfolio spans three waterproofing system families: torch-applied and self-adhesive SBS elastomeric membranes (TA-20, TA-25, TA-30, SA-20) with 20–30 year guarantees, hot-melt systems (HM-40) for zero-fall and podium applications, and liquid-applied systems (Paracoat polyurethane range and PR-15 PMMA). Supporting offerings include Decra stone-coated steel pitched roof tiles (supplied under an exclusive UK partnership), ParaDome and ParaGlaze rooflights, solar PV systems, biodiverse living roofs, blue roof sustainable drainage, and biophilic well-being solutions.

Langley monetises primarily through project-specific, quote-based sales of waterproofing systems combined with design, specification, and project management services, delivered via a two-tier model: direct engagement with architects, specifiers, developers, and building owners, with installation executed through a vetted Approved Contractor Network of specialist installers. Revenue streams include proprietary system supply, professional services (design, installation oversight, maintenance), training and apprenticeships delivered through subsidiary Langley Training Services Ltd, and solar PV hardware sales. The company differentiates on a unique Insurance Backed Guarantee (IBG) structure — ring-fenced premiums, TrustMark approved, Crystal Mark accredited, and fully transferable — and on a dense stack of third-party certifications (ISO, BBA, NFRC, TrustMark, CHAS, LABC, CITB, ROSPA). It serves education, residential (public and private), commercial, and broader public-sector customers, with no disclosed revenue, no external funding, and operations confined to the United Kingdom.
