SEALING AND PAINTING A COLORBOND ROOF AFTER PRESSURE CLEANING ... Is important for a few reasons. Colorbond metal roofing materials have a factory applied coating that protects the metal underneath. Pressure cleaning, especially if the surface is already aged or damaged, may strip this protective layer and if left exposed, the metal underneath can oxidize, leading to rust and corrosion over time, especially in coastal or humid locations. Sealing the roof after cleaning reinstates a protective barrier and painting the colorbond roof with a specialised roof membrane coating adds UV protection, moisture resistance, and helps preserve the structural integrity of the roof. Pressure washing can leave the roof looking patchy or dull, especially if the original paint or coating has faded. By sealing and painting the roof after cleaning, you can refresh the colour and even change the colour to update the look of your home. While pressure washing your colorbond roof cleans the surface and removes dirt, sealing and painting the surface afterwards ensures you are protecting your roof and prolonging its lifespan.
