This large flat pressed metal roof at Mountain Creek was seriously filthy. It was covered in slimy grime, mould and lichen. With the Jetts pressure wand we cleaned it up beautifully. No chemicals were required, just pure water under 2700psi of pressure. The surface of flat metal roofs like this aren’t always visible from the ground, so your flat roof could need a clean without you knowing. A pressure wash will extend the life of your roof, discouraging rust and other damaging effects of weathering.
