Those black streaks and green patches aren't just ugly — they're shortening the life of your roof. Our roof soft wash method uses safe, low-pressure techniques to remove algae, moss, and lichen without ever putting damaging pressure on your shingles.
If you've noticed dark streaks running down your roof, you're looking at Gloeocapsa magma — a type of algae that feeds on the limestone filler in your shingles. Left untreated, it spreads and can significantly reduce the lifespan of your roof. Moss and lichen cause even more damage, lifting shingle edges and allowing moisture underneath.
Georgia's warm, humid climate makes roof algae nearly inevitable. A professional roof soft wash treatment kills the growth at the root and leaves your roof looking years newer — all without the high pressure that can void your shingle warranty. Unlike pressure washing, roof soft washing uses a low-pressure application combined with a biodegradable cleaning solution to safely eliminate organic growth without risking shingle damage.
Algae and moss break down shingle materials over time. Regular cleaning can add years to your roof's lifespan and protect one of your home's biggest investments.
A clean roof dramatically improves how your home looks from the street — a key factor for resale value and neighborhood appeal in Lake Oconee and Madison communities.
Most shingle manufacturers recommend low-pressure soft washing. High-pressure cleaning can void your warranty — we always use the right method for the job.
Moss and lichen lift shingle edges, letting rainwater work underneath. Removing them prevents leaks and costly interior water damage before it starts.
We follow the roof soft wash method recommended by the Asphalt Roofing Manufacturers Association (ARMA). No power washing. No pressure damage. Just results that last.
We inspect your roof, identify the type and extent of growth, and protect any landscaping or sensitive areas around your home before we start.
We apply a biodegradable cleaning solution at low pressure that penetrates and kills algae, moss, mold, and lichen down to the root — not just the surface.
The solution dwells to ensure complete treatment, then we rinse thoroughly at low pressure, leaving your roof clean without lifting or damaging a single shingle.
We walk the property with you to make sure you're 100% satisfied before we pack up and leave.
