SIG Design & Technology is a part of SIG Roofing, a leading division of SIG plc, a FTSE 250 listed company and the UK's market leading specialist supplier to professionals in the building and construction industry. We 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.

We 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.

Our 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

These seminars set out a step by step process to help you establish the most appropriate solution in any particular circumstance. They work through how to establish the client’s brief, how to ensure compliance, and how to make the right cost decisions. In addition they detail what support to expect from suppliers and offer further sources of information.
