Super Simple 3 Step Process
Inspect
Every professional roof cleaning in the Portland area starts with a thorough inspection. At Anderson Exterior Maintenance, we carefully assess the condition of your roof to identify moss growth, algae, lichen, debris buildup, and any potential damage. This crucial first step ensures we tailor our soft wash roof cleaning approach to your specific needs while avoiding harm to your shingles or roofing materials. Our trained technicians understand the unique challenges of Portland’s damp climate, and by inspecting first, we can recommend the safest and most effective treatment. Whether it’s asphalt shingles, tile, or composite roofing, our Portland roof cleaning experts make sure your roof is ready for a deep, damage-free clean.
Clean
Before applying our soft wash treatment, we carefully scrub off large clumps of moss to prepare your roof for a thorough cleaning. In Portland’s damp, moss-prone climate, heavy moss buildup can trap moisture and lead to serious damage if left untreated. Our team uses gentle, roof-safe brushes to remove thick moss without harming your shingles. This crucial step allows our roof cleaning solution to penetrate deeper and kill any remaining spores at the root. By removing the bulk of the moss first, we ensure better long-term results and a cleaner, healthier roof. Trust our Portland moss removal and roof cleaning experts to protect your home and extend the life of your roof.
Treat
After we’ve removed large moss clumps and applied our eco-friendly soft wash solution, we move into Step 3: The waiting period . This crucial step allows the cleaning agents to soak into your roof’s surface and kill moss, algae, and lichen at the root , ensuring long-lasting results. In Portland’s cool and damp environment, the treatment typically takes 24 to 48 hours to begin working, with visible moss decay occurring over the following days to weeks . While it may take up to a month for all debris to naturally fall off, this slow and steady process is what makes soft wash roof cleaning in Portland so effective and safe. No pressure, no damage—just a clean roof that lasts.

How Long Do Roof Cleans Last?
A professional roof cleaning in the Portland area typically lasts 2 to 5 years, depending on factors like your roof’s material, surrounding tree coverage, and local weather conditions. In moss-prone regions like the Pacific Northwest, roofs exposed to shade and moisture may need more frequent cleanings—about every 2 to 3 years—to prevent regrowth.
At Anderson Exterior Maintenance, we use a soft wash roof cleaning method that not only removes moss and algae at the root but also helps slow down future growth. Our treatments continue to work for weeks after application, and results can last for years when paired with proper roof maintenance.

Is Roof Cleaning Safe For My Roof?
Yes—when done properly, roof cleaning is completely safe for your shingles. At Anderson Exterior Maintenance, we use a low-pressure soft wash method specifically designed to clean roofs without causing damage. Unlike pressure washing, which can strip away protective granules and shorten the life of your roof, soft washing gently removes moss, algae, and debris using eco-friendly cleaning solutions and minimal water pressure.
This method is ideal for asphalt shingles, which are the most common roofing material in the Portland, Oregon area. Our team is trained to assess your roof and apply the safest, most effective treatment for long-lasting results.
