Roof Cleaning & Pressure Washing Services in San Jose
Ever wonder what causes those ugly dark streaks on your roof shingles? It’s airborne blue-green algae and organic grime taking root on asphalt shingles and tiles. Our professional roof pressure cleaning system strips away heavy dirt, algae streaks, and moss buildup, restoring your roof’s clean appearance and protecting home value.
Common Roof Algae & Grime Problems We Fix
Bay Area humidity and shaded trees accelerate roof contamination. Here is why professional roof washing is essential:
Black Algae & Grime Streaks
Vertical black streaks spread rapidly across roof slopes, absorbing heat and making your home look aged. Our pressure washing system thoroughly strips away dark algae and dirt.
Thick Moss & Lichen Build Up
Moss growth traps moisture against shingles, causing surface degradation over time. Our controlled pressure washing removes thick moss clusters from tile and shingle surfaces.
Curb Appeal & Value Restoration
A dirty, dark roof drastically lowers home market value. Our expert cleaning techniques instantly restore natural shingle or tile colors for instant curb appeal.
