 What we do
SIG Design & Technology delivers a complete and impartial design and supply service built around its flat roof products (including green roofing systems and bespoke metal solutions) with the aim of enabling the roof to work harder.
We help roofing designers and contractors make their roofs save energy and carbon, generate energy and integrate with other technologies such as solar collection, drainage and heat pumps.
With decades of experience we’re familiar with many of the problems designers and contractors face when looking at getting the most from a roof, and have examples of successful projects you can use to satisfy your clients and insurers.
