What Happens When You Skip Roof Cleaning?
Neglecting your roof doesn't just affect curb appeal — it accelerates damage that leads to expensive repairs or early replacement.
Moss Destroys Shingles
Moss roots lift and crack shingles, breaking the protective seal and letting water seep into your roof deck — causing rot and structural damage over time.
Algae Weakens Protection
Those dark black streaks are algae feeding on the limestone in your shingles. Left untreated, it strips the granules that protect against UV rays and weather.
Debris Traps Moisture
Leaves, pine needles, and debris hold water against your roof surface — creating the damp environment mold and rot need to thrive, especially in Seattle's wet climate.
How We Clean Your Roof
A structured, proven 4-step process that protects your roof while delivering lasting results.
Roof Inspection
We assess the full condition of your roof — checking shingle health, identifying problem zones, and determining the safest cleaning method for your materials.
Soft Wash Treatment
We apply an eco-friendly, biodegradable solution at low pressure that kills moss, algae, and lichen at the root — without blasting or damaging your shingles.
Moss & Algae Removal
Manual removal of visible buildup, followed by a treatment coat that slows regrowth — leaving your roof cleaner for longer after every service.
Rinse & Walkthrough
A thorough final rinse, full magnetic nail sweep, and a complete walkthrough with you so you see exactly what was done and can ask any questions.
