About Absolute Waterproofing

Manufacturer knowledge, installer experience

Refurbished built-up roof with new rooflights beside a campus building, Coventry University
Coventry University: ten building roofs refurbished across a live city centre campus

Established in 2019, Absolute Waterproofing Ltd is a specialist commercial flat roofing and waterproofing contractor with a strong technical foundation and extensive industry experience. The company was founded by two directors with backgrounds in flat roofing manufacturing, which means we understand not only how roofing systems are installed, but how they are designed, specified and expected to perform over their service life.

Our aim is simple: to provide clients with reliable, technically appropriate and professionally installed flat roofing solutions, supported by clear communication and a high standard of workmanship. Because we work across every system and manufacturer, the solution is chosen on performance, longevity, budget and the roof itself, not on a single product.

We work predominantly in the commercial sector, from smaller roofing works through to large-scale projects, refurbishment, re-roofing and new build, nationwide from our two offices in Coleshill, West Midlands and Congleton, Cheshire.

Client feedback

What the people who appoint us say

"Absolute have always provided us and our clients with a quality product and service throughout and we have no hesitation in using them again on future works. Most recently at Guardian Angels school in Shard End, Birmingham, Absolute delivered a project over the summer period and the feedback on their performance and professionalism from the school was superb."

Matthew Leetch
Director, Spicer Surveys

"Given the very challenging situation with lockdown, they have been highly responsive and flexible in their approach. All works have been completed within agreed timescales. Worked flexibly over weekends, without additional cost, to ensure programme slippage due to bad weather was made up. No health and safety incidents reported on any site."
