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.
