To effectively clean metal roofs, start by inspecting the surface for dirt, debris, mold, mildew, or algae growth. Remove loose debris using a soft-bristled broom or leaf blower, working from top to bottom. Next, prepare a gentle cleaning solution—mixing warm water with a small amount of mild, non-abrasive detergent. Using a soft sponge or cloth, gently scrub the surface in sections, being mindful not to scratch the protective coating. For stubborn stains or organic growth, a diluted solution of white vinegar or specialized cleaner can be applied, followed by thorough rinsing with a low-pressure garden hose. Avoid using harsh abrasives, wire brushes, or high-pressure washers, as these can damage the metal finish and cause leaks.Tips 1:As a designer, I always consider how proper maintenance supports both the look and structural integrity of a space.
