About Flat Roof Products

One advantage of working with SIG Design and Technology is that we can help you choose the best products for each application, independently of any brand loyalty.  Selecting a flat roof  system is always a combination of design criteria, performance requirements and cost, and it is important to find a balance all three.

SIG Design & Technology offer a range of roofing products both for new build and refurbishment projects including single ply, liquid waterproofing, hot melt, zinc, copper and stainless steel roofing and cladding, and green roof systems.

Single Ply – Single ply roofing membranes are increasingly popular in UK construction projects, both for new build and refurbishment. SIG Design & Technology recommends a range of single ply flat roof membranes, different materials and different brands, depending on the application, project size and performance requirements. We supply Armourplan PVC, Spectrplan TPE, Rhenofol PVC and Rhepanol PIB. Find out more about choosing the right single ply membrane for your flat roof here.

Hot Melt – Hot melt is a membrane that is applied as a hot liquid directly to a prepared structural deck to create a completely seamless, monolithic layer. It is suitable for use as the waterproofing layer on most new build flat roof applications, when covered by suitable protection. SIG Design & Technology supply IKO PermaTEC Hot Melt, which was the first hot melt system to be manufactured in the UK.  Our blog post When to use Hot Melt is an introduction to hot melt roofing and structural waterproofing.

Liquid Waterproofing – Liquid waterproofing systems provide one of the most cost effective methods for making a new or existing flat roof waterproof. We have partnered with Hydrostop to supply AH-25, a wet-on-wet, cold applied liquid waterproofing product that is fully reinforced with a polyester fabric.  Find out more about on our blog post Liquid Waterproofing – when to use it on a roof.

Green Roofing – Our Green Roofing system called Verdiroof by Verdico has two things which make it special: the whole system comes in a single delivery, and the growing medium is carbon negative in production. As a result, these new products offer advantages to the specifier the contractor alike.  Find out more about Green Roof systems here.

Metal Roofing – We have assembled a rich portfolio of zinc, copper and stainless steel roofing and cladding from proven suppliers to help you choose the perfect metal roofing and cladding system. Find out more from SIG Zinc & Copper.
