What Is Roof Soft Washing?
Soft washing is a low-pressure cleaning method that uses specialized cleaning solutions to eliminate mold, algae, lichen, and moss from your roof without causing damage to shingles or tiles.
Unlike traditional pressure washing, which uses high PSI that can damage roofing materials, soft washing:
Uses low-pressure nozzles
Applies eco-friendly cleaning detergents
Kills contaminants at the root rather than just rinsing them off
Is gentle, safe, and effective
Think of it as a deep clean and disinfection for your roof, rather than a simple rinse.

Top 7 Benefits of Roof Soft Washing for Georgia Homes
1. Extends Roof Life
Soft washing removes contaminants that degrade your shingles and trap moisture.
2. Prevents Costly Repairs
Avoid rot, leaks, and structural damage by eliminating harmful growth early.
3. Boosts Curb Appeal
A clean roof drastically improves the look of your home—great for selling or appraisals.
4. Improves Energy Efficiency
Dark algae absorbs heat. Removing it helps your home stay cooler.
5. Kills Organic Growth at the Root
Pressure washing only rinses the surface. Soft washing kills algae, moss, and mold completely.
6. Safe for All Roofing Materials
Asphalt, tile, metal—soft washing works on them all without causing damage.
7. Complies with Manufacturer Warranties
Most roofing manufacturers specifically recommend soft washing to keep warranties valid.

Not sure if it’s time to clean your roof? Look for these common signs:
Black streaks or staining
Patches of green moss or lichen
Roof looks older than it is
Increased indoor humidity or attic smell
Water stains on ceiling (can indicate roof leaks)
You can’t remember the last time it was cleaned (more than 2 years)
How Often Should You Soft Wash Your Roof in Georgia?
In Georgia’s climate, the sweet spot is every 2–3 years—but it can depend on several factors:
Shade: Heavily shaded roofs need cleaning more often
Surrounding trees: More trees = more debris and organic growth
Roof color: Dark roofs show staining sooner
Humidity levels: High humidity = faster algae growth
Some homeowners opt for annual inspections to stay ahead of any buildup.
