Roof & Gutter Cleaning | Moss Removal | Soft Wash Treatment | Gutter Guards | Permanent & Christmas Lights. In the Pacific Northwest, moss is one of the main causes of premature roof wear. It holds moisture, lifts shingles, and gradually damages the structure over time. Many roofs are cleaned incorrectly. Pressure washing or aggressive brushing removes the protective granules from asphalt shingles and can significantly shorten the life of the roof. My approach is based on industry best practices and aligns with the guidelines of the Asphalt Roofing Manufacturers Association (ARMA), which recommends low-pressure chemical treatment as the proper method for cleaning asphalt shingle roofs. The goal is not just to make the roof look clean, but to remove moss safely while preserving the integrity of the shingles. For roofs with heavy moss buildup, I use a two-step process: 1. Careful manual removal Large moss clumps are gently removed by hand to reduce buildup without damaging the shingles. 2. Soft wash treatment The roof is treated with a professional moss-killing solution that eliminates remaining growth at the root level and helps prevent regrowth. After the initial service, the most effective long-term solution is maintenance. Future visits typically require only a soft wash treatment to keep moss under control. This avoids repeated scraping, protects the shingles, and extends the life of the roof — saving money over time. I also provide gutter cleaning and gutter guard installation to ensure proper drainage and help protect your home from water damage. In addition, I install Permanent and Christmas lighting systems with a clean, low-profile finish. Hidden wiring and secure mounting create a seamless roofline, so the lighting looks like a natural part of the home. Permanent systems can be used year-round for holidays, accent lighting, or special occasions. Owner-operated. Careful work, honest pricing, and clear communication.
