Founded in 1984, Polyroof is a long established and trusted name in the manufacturing of quality liquid applied flat roofing systems. From our high quality trim components to our BBA approved resins manufactured in accordance with ISO 9001 quality standards, our waterproofing systems are the number one choice when it comes to quality. Carrying our trusted insurance-backed guarantees and with certified BBA durability ratings of up to 30 years, Polyroof delivers real long term peace of mind and true value for money – never a cheap, quick fix solution.

Proven Guarantees

You might have seen other companies offering guarantees for 30, 40 or even 50 years. But how long have they been offering these guarantees, and what does their guarantee not cover? Polyroof have been issuing comprehensive, straight-forward and fully transparent labour and material guarantees since 1984, which are supported by independent insurance.

Independent Accreditations

We think our products are the best on the market, but you don’t have to take our word for it. Polyroof systems have been extensively tested and are fully accredited by leading third parties such as the BBA and FM. With proven durability ratings of up to 30 years and the highest rated fire performance, Polyroof systems have the credentials to give you total peace of mind.

Polyroof Approved Installers

Polyroof systems are only supplied to reputable contractors who have been trained and approved to use the systems. Our training and quality control checks are monitored by the British Board of Agrément under our BS EN ISO 9001:2015 quality scheme. All contractors are independent and have the local experience and knowledge to advise you about your roof.

Genuine Value for Money

Polyroof ’s exclusive, seamless and durable roofing systems totally eliminate all the shortcomings and short lifespan of traditional felt and bitumen materials. Unlike cheap GRP alternatives, Polyroof systems have been developed specifically for optimum roof performance, so they are flexible, highly UV resistant and achieve top fire performance ratings. Polyroof delivers real long term peace of mind and true value for money – never a cheap, quick fix solution.

Compliance with Regulations

Did you know that in order to comply with Building Regulations, a fibreglass or GRP roofing system must have BBA or ETA certification? Do you also know about the compulsory thermal insulation upgrades under Part L (England & Wales) regulations? Both your Polyroof approved installer and our Technical Team are on hand to ensure your roof will comply with all relevant legislation – and avoid any headaches in the future if or when you sell your home.

Committed to Our Customers

We operate to ISO 9001 Quality Standards, meaning our customer’s requirements are fully met at all levels. Our technical and customer support services will remain on hand right from the conception of your roof project. The ISO 9001 system also includes the training and monitoring of approved contractors, and is externally monitored every six months by third party companies to ensure compliance.

Polyroof Advanced Liquid Roofing Systems

This video, filmed in conjunction with the Liquid Roofing & Waterproofing Association, demonstrates how a Polyroof system can be installed – in this instance to a new plywood deck – and covers some of the system’s many benefits.

Polyroof roofing systems provide high performance and long-lasting waterproofing offer our clients genuine value. What you get with the Polyroof systems is complete peace of mind. Once it’s installed you never need worry about the roof deteriorating or leaking again. Polyroof Products Limited was incorporated in 1984 and has traded continuously thereafter. Investment over a sustained period has created an exceptionally strong asset base and an impeccable reputation and track record. This gives us the confidence to provide genuine guarantees that are as watertight as our roofing systems – something many of our competitors cannot do.

Your Polyroof will be guaranteed for up to 20 years but its service life will extend beyond that. In fact the Polyroof 185 system has been independently assessed by the BBA and is durability-rated for 30 years and the Protec system for over 25years.
Unfortunately not – unless you would like to apply to become an approved Polyroof contractor. Polyroof systems are only installed by approved, fully trained and accredited Polyroof contractors. This allows us to offer the third party accreditations and market-leading guarantees that make Polyroof different from cheaper, over-the-counter systems.
There’s a contact form on one of the tabs to the left that you can fill in to be provided details of your local Polyroof approved installer. Alternatively you can call us on 0800 58 77 77 5 for more details or email We have a wide network of contractors and there’ll be one covering your area.
Don’t worry, our contractors are not salesmen, they’re tradesmen – so no pushy sales tactics. They’ll simply measure your roof and work out a price. They’ll also show you examples of different colours and finishes so you can choose what best matches the style and character of your home.
Yes. Polyroof systems provide a tough, durable surface that takes normal foot traffic. It makes an attractive, easily cleaned and 100% waterproof finish for balconies, terraces or walkways, and can be given an anti-slip finish.
Polyroof systems were principally developed for flat roofs, but they are often used on pitched roofs. For example porch roofs or the roofs of sheds, summerhouses and outhouses are often given the Polyroof treatment.
Water ‘ponding’ is avoided by building in a slight fall (slope) into your new roof to run off water into the gutters. Your old roof is most likely covered in stone chippings, moss and lichen – which all encourage ponding anyway. There are no stones with Polyroof and it doesn’t attract moss or lichen. Even with your new Polyroof you may see some ponding but don’t worry, Polyroof is totally impervious to water.
If the roof is over a habitable room, for example an extension, then it needs to conform with current Building Regulations in terms of insulation ‘U Values’ and condensation control. Our contractor will advise you on what’s required when he surveys your roof. All of our systems can incorporate new insulation to provide you with a highly cost-effective thermal upgrade.

All Polyroof systems are approved by the British Board of Agrément. BBA Certificates have been providing authoritative and independent information on the performance of building products for over 35 years. Every BBA Certificate contains important data on durability, installation and compliance with Building Regulations throughout the UK. Polyroof systems uses fibreglass reinforced resins that have been specially developed for flat roofing. Don’t be taken in by companies offering cheap fibreglass roofing systems as they won’t be BBA approved and they’ll probably be using ordinary rigid fibreglass resins – which are not designed for use on buildings.

We’d recommend replacing existing guttering and fascia boards with uPVC. We stock high quality, maintenance-free uPVC roofline products that will complement your new Polyroof. Your Polyroof contractor can fit these at the same time as the Polyroof. Ask your contractor for details.
