Certain types of roofs require more frequent cleaning due to their material and exposure to environmental elements. Asphalt shingles, which are common in Washington, DC, are particularly prone to algae and moss growth because they retain moisture. Tile and slate roofs, while durable, can also develop mold and mildew in damp conditions, requiring regular maintenance to preserve their appearance and functionality.
Metal roofs tend to require less frequent cleaning because they are resistant to moss and algae, but they can still accumulate dirt and debris. If your home is surrounded by trees, you may need to clean your roof more often to prevent leaves and branches from piling up. Scheduling routine roof cleaning Washington DC services ensures that any roof type remains in top condition, reducing long-term maintenance costs.
