Black streaks or moss growing on your roof? B&B Exterior Cleaning provides professional roof cleaning in Spokane, WA using a safe, low-pressure soft wash system designed to remove algae, moss, and buildup without damaging shingles.
Protect Your Roof. Protect Your Investment.
Dark streaks are often caused by algae, while moss holds moisture against shingles and can shorten roof life. Improper high-pressure washing can cause serious damage. Our roof cleaning method is specifically designed to gently eliminate organic growth while preserving the integrity of your roofing materials.
Our Roof Cleaning Process
We apply a professional cleaning solution that targets algae and moss at the root. The solution works over time to break down buildup, restoring your roof’s appearance without the risks associated with high-pressure washing.
This method is safe for most asphalt shingle roofs and helps improve curb appeal while supporting long-term roof performance.
