Concrete Roofing Products Ltd

Concrete Roofing Products Limited (Company No 1142800) was first formed in 1970 as the manufacturing division of a long established family roofing business. The company has traded as Celstone since 2000, when production of roofing stone and slate from a sister company was relocated.

Directors of the company are Max Abraham, Jeremy Abraham and David Poole. Jeremy is also a director of the sister company, Max Abraham Roofing Contractors Limited, who specialise in roofing contracts, the supply of new and reclaimed roofing materials and is a member of the National Federation of Roofing Contractors.

Celstone manufactures a comprehensive range of roofing products from both concrete and GRC.


Our ridge tiles are manufactured from concrete using both modern machinery extrusion processes and by hand. Ridges come in a number of lengths, varying angles, have a through body colour and can have an acrylic coating or granular finish.

Air, gas and tile vents are made using new tiles and ridges or can be manufactured using reclaimed or the customers own roofing materials.
