Faced with a tight budget, Cure Roofing Ltd, installed a lower cost and lightweight alternative to zinc with the same visual impact earning it and Polyroof the Small Project Award.
The client wanted a new roof for an extension, which matched the original building’s aesthetics. The roof covering had the same visual impact as zinc but at a lower cost, in keeping within their strict budget. The Polyroof alternative, which was installed by Cure Roofing Ltd, not only brought cost savings, but is lightweight, totally seamless and pigmented with RAL 7016 to provide an anthracite grey colour, faithfully simulating the appearance of contemporary zinc roof sheets.
What Cure Roofing says
Having originally considered a zinc sheeted system, the owners discovered Polyroof and quickly concluded that their simulated metal finish roofs were the best on offer. Cheaper than traditional metals; lightweight; totally seamless; pigmented to any RAL colour; no scrap value—lower risk of theft.
Complexity
After discussions with Cure Roofing, a Polyroof simulated metal finish was proposed as a roofing solution that would meet all the client’s requirements. In addition to bringing important cost savings to the client who was operating to a strict budget, the Polyroof solution was lighter in weight, totally seamless and could be pigmented to any RAL colour. Having no scrap value, the client also had the added peace-of-mind that the roof would not be a target for theft.

Workmanship
Cure Roofing constructed a timber warm roof, which incorporated 120 mm PIR insulation to achieve a U-Value of 0.18 W/m2K in compliance with building regulations. An OSB3 TG4 deck was fitted above the insulation and Polyroof pre-formed GRP standing seam trims were fixed at 600 mm centres into the deck.
Next, the first coat of the waterproofing system was applied over the whole roof area and the standing seam trims. Once dry, the roof was meticulous sanded to create a smooth, totally defect-free surface. The roof was finished with a second coat of Protec pigmented to RAL 7016 providing an anthracite grey colour to the whole roof, faithfully simulating the appearance of zinc roof sheets.
