Roof Cleaning — Louisville & La Grange, KY
Gloeocapsa Magma algae — that black streaking — doesn't just look bad. It's eating your shingles from the inside. CleanRidge uses soft wash chemistry to kill it at the root. Results last years, not months.
A hardy algae that feeds on the limestone filler in your asphalt shingles. It doesn't just sit on the surface — it digests the shingle from below. Left untreated, it shortens your roof's lifespan by years.
High-pressure washing blasts granules off your shingles — the same granules that protect against UV and water damage. Once they're gone, they don't come back. Your warranty may be voided too.
Most companies spray the stain and call it done. Within 12-18 months the algae is back — sometimes worse, because the surface is now more hospitable. They didn't kill the root. Only chemistry does that.
We use the same sodium hypochlorite and surfactant blends that ARMA (Asphalt Roofing Manufacturers Association) recommends — applied at the right concentration for your specific roof type.
The core service. We apply a biocide solution that kills algae, moss, and lichen at the root — then let it work. No pressure, no damage, results that last 3-5 years.
Siding, brick, stucco — soft wash works on your entire exterior. We treat mildew, oxidation, and environmental grime with the same low-pressure care we use on roofs.
Clogged gutters trap moisture against your trim and foundation. We flush and clean them while we're on site — paired with roof treatment at a discount.
Churches, apartment complexes, office parks, HOA communities. We handle multi-building properties with volume pricing and scheduled maintenance programs.
We come to your property, inspect the roof type and condition, assess algae coverage and landscaping, and give you a firm price on the spot. No satellite measurement games. No inflated estimates.
We apply a sodium hypochlorite and surfactant solution at low pressure. It soaks into the shingle pores, kills the algae at the root, and begins breaking down the organic buildup. We protect your landscaping first.
We rinse the roof gently once the dwell time is complete. The result: a clean, restored surface that resists regrowth for 3-5 years. We do a final walkthrough with you. Your satisfaction is guaranteed.
Every CleanRidge roof treatment comes with a 5-year spot-free warranty — if algae returns in the treatment zone within 5 years, we come back and retreat it at no charge. That's not marketing fluff. It's a written guarantee backed by real chemistry.
CleanRidge is built for Kentuckiana homeowners who want the job done once, done right, and guaranteed for five years. We're not the cheapest option, and we're not trying to be. We're the one you'll never have to call again.
