Design Services

SIG Design & Technology’s design team can provide much of the information needed to ensure the roof’s design and the performance it is expected to deliver.

Drawing on the expertise of our partners throughout the roofing industry, we are uniquely positioned to consider the widest range of roofing solutions from which to recommend an optimum design.

Our design service gathers the components needed to provide detailed specification options including:

  • Statutory requirements, planning regulations and product standards
  • Surveys of existing roofs
  • Access, usage and the financial and environmental benefits of roof top living and green roofs
  • Exposure ratings and wind uplift calculations
  • Design ideas along with structural implications and requirements
  • Drainage and water run-off calculations
  • Thermal and acoustic insulation performance calculations
  • Condensation risk analysis
  • Safety at height considerations
