A comprehensive report on Sydney Fish Markets
The system entailed repairing all roof sheeting fixtures and fittings, modifying the inadequate box gutters to cope with severe storm conditions, covering the roof with a thick urethane acrylic UV stable trafficable membrane (AcryFlex) and finally, applying a top coat of a Solarcoat heat re-radiating membrane to stop nearly all heat from entering the roof / facility.
The roof was over 40 years old, it has been previously patched and membrane coated. All previous repairs had not led to a long-term leak-free roof with the absence of rusting and severe sheeting degradation. The previous membrane extensively bubbled and was peeling off.
The low roof pitch and extremely shallow box gutters have been incapable of removing the water from the roof quickly enough during heavy rain periods and this aspect caused additional damage and leaks.
