#Perfect Roof - Hot Melt Waterproofing - BREEAM - Rainscreen - Hydrostop - NedZink

Choosing the Best Roofing System for the Job

SIG Design and Technology has put together an 8-step guide to identify the challenges and ensure that a roof’s design meets your building’s requirements. Called #Perfect Roof, the eight steps follow the process from product selection and design expertise through to full guarantees and planned maintenance. Its know-how is just part of the service that is provided absolutely free to customers.

Make Architects chose hot melt waterproofing for 5 Broadgate, the UBS new City of London headquarters. Just 12 storeys of offices yield over 65,000m² of high-spec office space, including four football pitch-size trading floors and 7,500m² of concrete-decked roof and terraces. The system was chosen because it could be installed much more quickly, was easier to protect, had a longer lifespan and was more cost-effective. UK production gives it efficient carbon delivery miles. It is produced with zero wrapper waste which reduces on-site waste, making a small contribution towards British Land’s ‘Zero Waste to Landfill’ commitment and towards BREEAM Excellent for the project at design stage.

The waveform roof finish to this Peak District bottling plant in bottle green (close to RAL 6007) reflects the rolling hillside nearby. The architects, Fletcher-Rae chose locally manufactured IKO Armourplan Premium PVC on its BREEAM excellent credentials. The 12000m² single ply roof provides the waterproofing over foil-faced insulation on a metal deck. This curved roof, even in a bespoke colour, was competitive against panel roofing systems.

There is nothing like a real metal roof. Its spectacular looks and crisp lines really do bring out the qualities of a building’s design, and today there are a range of pre-patinated and painted finishes available to meet most budgets. Metals can be used on the whole building envelope, providing scope for aesthetic applications. Performing well at pitches between 5 and 90 degrees, zinc, copper, stainless steel and aluminium sheet can follow curves and angles, making it the perfect cladding material for more unusual forms.

Sister company SIG Zinc and Copper provide a broad portfolio of metals from which an architect can choose by performance, finish and budget; from high quality off the shelf or bespoke shingles, to double lock standing seam and rainscreen panel systems. Choose from well-known pre-patinated and Verdigris copper or more unusual mirror finish and rainbow coloured products. Make use of our full design and specification service, accredited contractors, inspection and maintenance advice backed up with reliable guarantees.
