Reliable, experienced roofing contractors

With our SIG Design and Technology Accredited Contractor scheme (DATAC), we can ensure the roofing systems we design are installed exactly as they should be. Only experienced roofing contractors are invited to join DATAC. To qualify they must:

  • Demonstrate an exceptional knowledge of a particular roofing system
  • Have an on-going, proven record of installing it
  • Have suitable management skills and quality-assurance procedures
  • Be members of a relevant trade association
  • Have up-to-date insurance cover

As an essential part of our service to academies, we will only recommend DATAC contractors, with experience of working in educational environments, to install the systems we have specified. Contractors are selected depending on their ability to successfully manage and deliver the project – with minimal disruption to ongoing school activities – and these are recommended to the client and invited to quote for the work.
