About Topseal Systems Ltd

Topseal offers a range of advanced GRP roofing systems including the innovative new Topseal Direct Lay system. Fitted through a national network of highly-trained and approved installers throughout the UK.

With full BBA certification and up to 40 years' materials and workmanship guarantee (with Topseal DoubleTop), Topseal is the ultimate, stylish roofing system.

The Topseal roofing system is installed nationwide and has proven pedigree as a waterproofing material with an expected lifespan of 100 plus years.

A Topseal roof consists of specially formulated Topseal roofing resin and topcoat cold-applied on site with our heavyweight GRP edge trims to create a bespoke, seamless roof to suit the application.

Domestic Roofing
Topseal offers a range of roofing solutions for common domestic applications such as extensions, garages, dormer roofs, parapet walls, gulleys, gutters, conservatories, orangeries and many more.
The versatility of Topseal will ensure that it will fit in with almost any style from ultra-modern to traditional listed buildings, providing long-lasting performance and style through the most extreme weather conditions.

Commercial/Industrial Roofing
Topseal is widely used for a variety of commercial and industrial applications. Our system is cold applied without the need for heat or flames, and cures within an hour of installation, making it much quicker than many other liquid-applied systems and coatings.

Refurbishment Roofing
The Topseal Direct Lay system can be installed directly onto the existing substrate, including felt, ashphalt, GRP and concrete.

Simulated Lead/Copper
Topseal is used extensively as a lead/copper replacement or alternative for roofs, gutter linings and complex architectural detail work. For listed buildings, Topseal can also be used to simulate rolled joints without seams. Colour matching can be achieved by using a topcoat with a lead grey or copper-green finish, providing like-for-like appearance and longlasting performance with a guarantee of up to 40 years.
Topseal is also free from the toxic-water runoff associated with lead and copper, and deters criminal damage due to its high durability and low effective scrap value.

Balconies, walkways and stairs
For heavy-duty applications, such as balconies, walkways, terraces, roof gardens and steps, Topseal HD provides an extra level of performance and waterproof protection, with a 25 year guarantee on areas subject to frequent foot traffic.
The system is fitted with a choice of our coated aggregate finish which is available in any of our standard colour options or matched to most RAL, or BS4800 colours or our anti-slip finish for extra grip in wet conditions.

Green Roofs
Topseal GreenTop can be used to create a totally bespoke green roof with a low maintenance sedum green roof, or prepared to suit third party supply of the green roof.
As well as creating a naturally beautiful area, Topseal GreenTop adds sound insulation to your property and delivers energy savings, as it protects your property from internal temperature fluctuations in the summer and winter months. The system is provided with Topseal’s class-leading 25 year watertight guarantee for peace of mind.

Water containment
When you demand the ultimate in style, versatility and performance for critical water containment, Topseal DoubleTop is the perfect answer. Topseal DoubleTop can deliver guaranteed performance under water for at least 25 years, enabling you to create a versatile and stylish pond, pool, wet room or practically any environment where you need guaranteed protection.

New Direct Lay roofing system!


The Topseal Direct Lay System is a ground-breaking liquid-applied GRP roofing system for new build and refurbishment flat roofing projects. The seamless system can be specified for almost any project regardless of size or complexity, without the inconvenience of removing the existing roof when used for refurbishment or directly onto tissue-backed insulation for a warm-roof configuration.

Topseal Direct Lay, can be applied directly to a range of materials including felt, asphalt, concrete and tissue-backed insulation and all components are completely cold-applied, which eliminates the risks associated with the use of heat or flames used during installation. As with all Topseal systems, Topseal Direct Lay is only installed by Topseal trained and approved installers and the system comes with a 20-year guarantee of workmanship and material performance.

Topseal offers a range of advanced GRP roofing systems fitted through a national network of highly trained and approved Installers. Since the company’s GRP system was first introduced back in 1992 it has been installed on millions of square metres of roofs all over the UK. Topseal is the ultimate fibreglass flat roofing system suitable for both domestic and commercial works. The Direct Lay system is suitable for new build and refurbishment flat roofing projects with an optional guarantee protection certificate. It ensures minimal disruption on site and no landfill as no removal of the pre-existing roof is necessary.
