Topseal fibreglass roofing system is used extensively as lead substitute roofing and copper substitute roofing 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 long lasting performance with a guarantee of up to 40 years.

Topseal is also free from toxic water runoff associated with lead and copper and deters criminal damage due to its high durability and low effective scrap value.
