The combination of airborne moisture and sunlight in the Brooklyn area means any home can become a victim of unsightly roof “stains” (which are actually an algae growth that thrives in such conditions). But before you even consider costly roof replacement, you should know that we strictly follow roof manufacturer’s cleaning guidelines. We do so using our proven safe and effective Low Pressure Roof Cleaning method. Our low pressure application is the kind of cleaning your Asphalt Shingle, Tile, Cement or Flat Tile Roof needs to look fresh and new again – and stay looking that way for a longer period of time than you would find with standard pressure washing methods.
