The Materials We Trust
EPDM Rubber
Fitted in a single sheet for standard flat roofs and sheds. Completely cold-applied, fire-safe, and expands naturally with the weather to prevent tearing.
Liquid Polyurethane
Ideal for roofs with skylights, complex HVAC units, or awkward geometry. It cures to form a 100% seamless, impenetrable rubber-like seal.
Frequently Asked Questions
What is the best material for a flat roof in the UK?
EPDM rubber and liquid polyurethane. Unlike traditional felt, they are highly UV stable, seamless, and do not crack under temperature changes.
Can you put a liquid roof over an existing flat roof?
Yes. If the underlying timber is structurally sound, a liquid membrane can often be applied directly over the existing felt, saving removal costs.
