The Topseal system can be used on almost any type of roof from large scale commercial projects to common domestic applications such as extensions, garages, dormer roof, 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 bespoke ultra-modern to traditional listed buildings in simulated lead or copper finishes, providing long-lasting performance and style, even in the most extreme weather conditions.

- Simulated lead/ copper:

Topseal is used extensively as a lead replacement or alternative to copper for roofs, gutter linings and complex architectural detail work. For listed buildings Topseal can also be used to simulate rolled rib joints. Colour matching can be achieved by using a topcoat with a lead grey, zinc grey or copper green finish, providing a like-for-like appearance and long-lasting performance, without the need for expensive highly skilled labour. Topseal is free from toxic water run-off associated with lead and copper and deters criminal damage due to its high durability and has no effective scrap value.
