SIG Design & Technology is a part of SIG Roofing, a leading division of SIG plc, a FTSE 250 listed company and one of the UK's market leading specialist suppliers to professionals in the building and construction industry. They design and supply flat roofing solutions including green roofing, zinc, copper and stainless steel roofing and cladding and pitched roof coverings including natural slate and clay tiles.

They have put together an 8-step guide to identify the challenges and ensure that a roof's design meets a building's requirements.

Called #PerfectRoof, the eight steps follow the process from product selection and design expertise through to full guarantees and planned maintenance.

Their know-how is just part of the service that is provided absolutely free to customers.

SIG Design Technology have developed two RIBA Core Curriculum approved CPDs:
•A structured approach to roof specification and design
•Specifying hard metals: choosing the right product for the project
•Roof refurbishment: choosing the best solution

Subscribe to their Roof Design Technical Blog at http://www.singleply.co.uk/blog/ to receive useful, technical advice and information on designing flat roofs, green roofs, single ply and zinc roofs.
