The answer to 'how to clean roof' is to regularly clean and maintain your roof to extend its lifespan and prevent damage. This typically involves removing debris like leaves, branches, and moss, as well as washing the roof surface to remove dirt, algae, and other buildup.
For a basic roof cleaning, you can use a soft-bristle brush, a garden hose, and a mild detergent or roof cleaning solution. Be sure to work safely and avoid walking directly on the roof if possible. If your roof has significant moss or staining, you may need to use a roof cleaning solution with bleach or other stronger chemicals. In some cases, professional roof cleaning services may be required for thorough, effective cleaning.
