The past few years have seen major advances and improvements in the materials used in modern roofing technology. A specifier now has renewed confidence to take full advantage of the benefits flat and low-pitched roof designs can offer.
Flat roofs provide opportunities for planning and design flexibility, for example; terracing, roof-top gardens, patios, car parks, delivery areas, building services and ventilation equipment and the ability to add additional storeys at a later date.
Large area roofs or irregular shaped buildings can be completed more quickly, easily and cost effectively than a pitched roof.
Flat roofs also allow easy access to natural light and because of the simple construction, internal partitioning is easy and particularly advantageous for commercial or industrial buildings.
