Final Walkthrough & Cleanup—Satisfaction guaranteed
Soft Wash vs. Power Wash: What’s Right for You?
Soft Washing (Recommended for asphalt shingles, tile, and delicate materials):
Uses low pressure and a biodegradable solution to kill mold, algae, and lichen at the root. It’s gentle on your roof and long-lasting—recommended by roofing manufacturers like GAF.
Low-Pressure Power Washing (Safe for metal and select flat roofs):
Uses carefully controlled pressure to rinse away buildup and debris when surface agitation is necessary. We’ll assess your roof type and condition to recommend the safest and most effective method.
