The roof and gutters on this house at Peregian Springs needed a clean. Using the Jetts surface cleaner, we cleaned the entire roof, including all the valleys. We also cleaned the solar panels to ensure maximum efficiency. Over time, colorbond roofs like this one gradually get dirty, grimy, mouldy, and covered with lichen. The longer it’s left, the worse it gets. By cleaning the roof and gutters at least once per year, you can ensure a good looking roof for many years to come.
