Polyroof systems have been specified by leading developers and house builders for over 30 years. With their extra-tough, impact-resistant and hardwearing finishes that resist damage from other trades, our systems provide peace of mind that they will remain waterproof for decades to come from the moment they are installed. Polyroof systems are available in a range of colours and finishes to complement a development’s aesthetics and are suitable for all roof designs.

Achieve A+ Ratings with Polyroof Systems

The Green Guide to Specification by BRE Global forms the basis of construction material ratings for BREEAM assessments. Cold-applied liquid roofing membranes, such as those manufactured by Polyroof Products Ltd, have been recognised by BRE to help roofing elements achieve up to an A+ rating (depending on the roof construction).

This is a reflection of the sustainability and low environmental impact of cold-liquid applied roofing membranes. For more information on BREEAM please visit www.bre.co.uk/greenguide or call the Polyroof Technical Team on 0800 801 890.

Let Polyroof Take Responsibility for Your Roof

Polyroof’s reputation has been built on the high level of technical support provided to clients before, during and after every contract. We like to work closely with our clients from the very beginning of a flat roofing project right through to completion and throughout the lifespan of the roof. From our experience, this is the best way to guarantee that all aspects of the roof are finished to the superior standards that our clients expect.

Importantly, we understand that our clients are often tasked with many responsibilities during a construction or refurbishment project. Flat roofs mean a great deal to us, but we know our clients have plenty of other aspects of a project to focus on.

This is why we strive to take on board as many of the challenges and issues associated with the flat roof that we can, freeing up our clients’ time so they can focus their efforts where they are needed most.
