Tile roofs are usually more difficult to clean than metal roofs. Because they are porous, the grime gets right in to the tile, making it harder, and more time consuming, to remove. Using the Jetts pressure wand and pure water, we blasted the grime off each tile on this large two storey house in Noosaville. The tiles came up looking great. As part of this job, we also cleaned the gutters, external walls, fences and driveway.
