History of Sika Roofing

Research and Development Centre

It was more than 60 years ago that Sika launched into the UK roofing business. This began with the acquisition of Sika Sarnafil - already established as the UK market leader of single-ply systems. We continue to innovate the proven performance of our membranes and have established the first UK Silver Certified single ply membrane in Cradle to Cradle, Sarnafil Advanced Technology

Continuing to innovate and grow within the UK flat roofing market, Sika acquired UK manufacturer, Sika Liquid Plastics, the market leader in cold-applied liquid waterproofing technology. Through this, Sika acquired the manufacturing plant in Preston, Lancashire where the research and the development of our innovative cold-applied waterproofing systems for roofs, walkways, balconies and terraces progresses for our Global roofing customers.

Roofing Solutions

In 2020, Sika understood the requirement for a bituminous solution for our customers to be able to provide solutions for all roof types and project requirements. To ensure the same premium products alongside our single ply and liquid applied systems, Sika acquired the largest bituminous manufacturer in Europe and created a new product range, SikaBit, for the UK market. As our bituminous offering in different countries continued to grow, SikaBit was rebranded in 2022 to SikaShield for all bituminous products by Sika.

Today Sika can offer all flat roof waterproofing solutions for both new-build and refurbishment projects, depending on the projects and clients requirements and following the latest building regulations.
