The SIGA Heritage Range of reproduction natural stone roofing products are hand crafted to give an authentic roofscape, offering detailed moulding, a choice of colours and a range of sizes designed as alternatives to Cotswold stone, Collyweston slate and Swithland slate.

The glass fibre cement construction provides a light yet durable roofing material. An easy to lay format and a range of compatible products, including ridges and in-line ventilation systems, create an extremely versatile and cost effective alternative to natural products.

Each individual slate is hand crafted using moulds taken from stone slate originals.
As with natural stone, shades vary, with no two slates being identical. This, combined with the surface detail and hand colouring, ensures a truly authentic roofscape.

SIGA Heritage Reproduction Stone roofing slates have been designed in consultation with professional roofers and architects, to achieve an easy to lay slating format, resulting in a coursed and diminishing stone slate roof.

The roof slates are constructed from Glass Fibre Reinforced Concrete (GRC) producing a strong and durable slate weighing only 65kgm2, 20% lighter than natural stone roofing.
Their construction allows them to be cut easily, without cracking or breaking, and the 100% through colour means that they look like stone when cut.
