Exposure to the harsh West Australian climate cause Colorbond roofs to breakdown. They become powdery and have a streaky appearance.
At Rainbow Roof Restorations in Perth we restore the roof by cleaning it with a high pressure water cleaner. The roof is then primed and 2 coats of acrylic roof coating is applied, which is developed to withstand the harsh conditions.
This is an alternative to the costly expense of re-roofing.
