Our Equipment
Our Roof Washing Equipment
Professional Soft-Wash System
Low-pressure nozzles apply our roof-cleaning solution at the right volume to kill algae without the high pressure that can dislodge asphalt granules and shorten roof life.
Eco-Safe Biodegradable Detergents
Our roof-wash chemistry targets Gloeocapsa magma and moss at the cellular level, then breaks down safely — protecting your landscaping when we pre-rinse and post-rinse.
Water-Fed Poles
Telescoping poles let us reach second-story roofs and steep pitches from the ground or gutter line, reducing foot traffic on your shingles.
How It Works
Our Roof Washing Process — Step by Step
Inspect the Property
We walk the property and identify sensitive surfaces, landscaping, and areas that need extra care before a single drop of water touches your home.
Apply Pre-Treatment
We apply the right pre-treatment or detergent to loosen dirt, grime, and mildew at the source so the surface cleans thoroughly and evenly.
Clean at the Right Setting
We clean at the correct pressure or soft-wash setting for that specific surface — never more pressure than the material can safely handle.
Final Walkthrough
We walk the job with you, backed by the Alpha Clean Guarantee — if it is not perfect, we come back and make it right.
Why It Matters
Why Columbus Homeowners Choose Professional Roof Washing
DIY roof cleaning is one of the riskiest projects a Columbus homeowner can take on. Walking on a roof is dangerous, and pressure washing — even at moderate settings — blasts away the protective granules on asphalt shingles, voiding most manufacturer warranties and shortening the roof's lifespan. Bleach-and-water mixes bought at the hardware store often streak the roof, kill landscaping, and leave algae behind to regrow within months.
Professional roof washing protects your home's value by eliminating the organisms that literally eat your shingles. Gloeocapsa magma feeds on the limestone filler in modern asphalt shingles, causing premature granule loss and curling. The right technique — low-pressure soft washing with the correct detergent concentration — kills the algae at the root and restores your roof's original color without damage.
For Central Ohio homeowners, a clean roof also means lower energy bills. Dark algae streaks absorb heat, making your attic and living spaces hotter in summer. Alpha Power Washing LLC delivers the Alpha Clean every time, protecting your roof, your warranty, and your investment.

Questions
Frequently Asked Questions — Roof Washing in Columbus
How much does roof washing cost in Columbus?
Roof washing in the Columbus area typically ranges from $300 to $750 depending on roof size, pitch, and the severity of algae growth. We provide a free, no-obligation quote so you know your exact price upfront.
How long does a roof wash take?
Most residential roof washes take 2 to 4 hours. Steeper roofs or those with heavy moss and algae may take longer, and we'll include an estimated timeframe with your quote.
How often should I have my roof washed?
In Central Ohio, we recommend roof washing every 3 to 5 years. Homes in shaded, wooded lots may need more frequent treatment to prevent algae from returning.
Is soft washing safe for asphalt shingles?
Yes. Soft washing is the only method recommended by roofing manufacturers. It uses low pressure and specialized detergents to kill algae without dislodging the protective granules that high-pressure washing would blast away.
