To effectively clean moss off your roof, start by prioritizing safety: use a sturdy ladder, wear slip-resistant shoes, and avoid working alone. First, gently remove loose moss with a soft-bristle broom or brush, sweeping downward to protect shingles. Next, apply a moss-killing solution—commercial moss removers, diluted bleach (one part bleach to three parts water), or vinegar are popular choices. Allow the solution to sit for 15-20 minutes, but don’t let it dry completely. Afterward, carefully rinse the roof using a low-pressure garden hose, never a pressure washer, as high pressure can damage the roofing material. To prevent regrowth, keep your roof free of debris, trim overhanging branches for better sunlight exposure, and consider installing zinc or copper strips along the roof ridge; these metals naturally deter moss.Tips 1:As a designer, I always recommend visualizing your exterior as part of your home’s overall aesthetic and function.
