Steam cleaning is one of the most effective methods for cleaning a roof. It delivers instant results while offering an eco-friendly alternative to chemical treatments such as biocides. The high water temperature eliminates a wide range of organisms, including algae, moss, lichen, mould, and mildew. Steam cleaning not only kills these organisms but also removes their root systems, preventing regrowth. Just as uprooting a weed is more effective than trimming the surface, steam cleaning fully removes moss for longer-lasting results.
