Choosing the Best Roofing System for the Job

SIG Design & 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 #PerfectRoof, 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 free to customers.

Between the towers of MediaCityUK and Michael Wilford’s The Lowry in Manchester, sits a small but perfectly formed gold parcel – a new home for The Alchemist cocktail bar and restaurant. The choice of metal cladding suited the precise geometry of the building form, and zinc on all surfaces hit the brief for visual quality for all angles – including the roof. Sister company SIG Zinc & Copper provides a broad portfolio of metals from which an architect can choose by performance, finish and budget. 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.

Make Architects chose hot melt waterproofing for 5 Broadgate, the UBS new City of London headquarters. The system was chosen because it could be installed quickly, was easier to protect, had a longer lifespan and was more cost-effective. UK production also gives it efficient carbon delivery miles. It is produced with zero wrapper waste reducing onsite waste, making a small contribution towards British Land’s ‘Zero Waste to Landfill’ commitment and towards BREEAM Excellent for the project. SIG Design & Technology used their know-how and professional expertise to secure the government’s Condition Improvement Funding (CIF) for roof repairs to a 1740m² project at St John’s School, Bishop Auckland. SIG designed the roof, which was complex in parts, and consisted of a mix of complementary interfacing products comprising the SIGnature bituminous roofing system, Armourplan single ply PVC membrane and Steadman’s composite panels.

SIG Design & Technology has launched a new website specifically for schools called FixMySchoolRoof.com that provides advice and information about school roofs and explains how schools can obtain grant funding for repairs and replacement.
