Old-school roof for factory revamp

To preserve the original look of the former signature Lion Match factory’s roof, Global Roofing Solutions supplied about 6 000m² of its 0,8mm 3004 Aluminium, Brownbuilt 406 roofing profile with a polyvinylidene difluoride (PVDF) coating in marble white. Located in Umgeni Road, Durban, the factory was built in 1926, but closed in June 2001. Property developers JT Ross bought the property with the aim of converting it into a commercial precinct with about 20 000m² of office space. The current renovation is the final phase of the Lion Match Office Park conversion.

efforts were put in to restore the original features.

Richard van Heerde from roofing contractor Browndeck Roofing explains that Brownbuilt is an old roofing profile that is not commonly used anymore, but was ideal for the purpose of this project and perfectly suited the aesthetic of this heritage building. While the building is receiving a facelift, efforts were put in to restore the original features. “What you’ve got in that building is the Rolls Royce of roofs – a good solid old product with a PVDF paint finish which is supposed to last 30 to 40 years,” he says.

The Brownbuilt profile is traditionally roll-formed from ISQ 300 Galvanised steel in continuous lengths. For Lion Match, however, it was roll-formed from 3004 Aluminium due to Aluminium’s excellent corrosive properties. It has three standing ribs at 203mm centres, giving a net cover of 406mm. The rib height is 48mm and provides capillary breaks, with each pan incorporating two stiffener ribs.

According to Van Heerde, the Brownbuilt roofing profile handles water very well. “The depth of the profile is one of the major benefits,” he points out, “especially when working with
a low-pitched roof, since it can carry a lot of water.”

With the project nearing completion, one part of the main building’s roof still needs to be replaced. Browndeck Roofing is scheduled to commence work at the end of June this year after the offices in that part of the building have been vacated. According to Van Heerde, the fact that the building was occupied throughout the renovation has probably been the main difficulty since their access to the building was limited. However, despite this challenge, the roof was delivered timeously and is performing as expected.
