What Sika Liquid Plastics does

Sika Roofing is the UK Roofing Division of Sika Limited, itself a wholly-owned UK subsidiary of Sika Group, a Swiss-listed (SIX: SIKA) specialty chemicals and construction materials multinational. The business designs, manufactures and supplies flat-roofing systems for new build and refurbishment projects across education, healthcare, housing, industrial, retail and data centre end markets in the United Kingdom, with technical support drawn from Sika Group professionals based in over 85 countries.

The portfolio is built around four proprietary technology platforms: liquid-applied membranes (the Sikalastic range, anchored by Sikalastic®-625 BMS), single-ply membranes (Sarnafil® AT, PVC and FPO), bituminous membranes (SikaShield® Pro, Classic, Essential and Hot Melt Structural Waterproofing), and integrated sustainability systems (Green, Blue, Solar and BioSolar roofing). Differentiation rests on rigorously tested formulations, project-specific specifications tailored to building use, environmental exposure (wind, rain, snow, hail), and a regulatory/compliance posture backed by British Board of Agrément certificates and CCPI reassessment. The customer-facing footprint is reinforced by an Approved Contractor Scheme of trained, certified installers who are the practical channel for warranty-bearing project delivery.

Sika Roofing monetizes through one-time product sales (membranes, primers, sealants, accessories) across its four platforms, alongside professional services revenue from bespoke specifications, an Approved Contractor training/certification scheme, and CPD presentations and e-learning. Go-to-market is enterprise specification-led: products are written into tenders by architects, surveyors and consultants, with the Approved Contractor Scheme acting as the delivery channel for a tiered customer mix that ranges from individual consumers (via the Roof Assured by Sika channel) through mid-market projects to large institutional jobs such as the £7.5m Stanley Buildings Blackpool redevelopment and a 70m² Manchester Metropolitan University installation. Pricing is quote-based and not publicly disclosed.
