Why It Happens
Why White Roofs Turn Dark
Flat Roofs Hold Moisture
Low-slope TPO membranes drain slowly, and standing moisture plus sun-warmed surfaces are exactly what algae, mold and mildew need to take hold and spread.
Growth Costs You Twice
A darkened membrane stops reflecting sunlight — driving cooling costs up — and the growth itself holds moisture against the seams and fasteners, aging the roof prematurely.
The Problem with 'The Other Guys'
Risky
Pressure washing applies over 1,000 psi of pressure, forcing water underneath the welded seams of TPO roofs -- essentially simulating a hurricane on your roof! This results in the weakening of your welds, causing long-term damage, and voiding manufacturer warranties.
Inefficient
Pressure washing lacks staying power, failing to remove organic growth at its roots. Just like watering a plant, pressure washing actually promotes regrowth of stains. In addition, the process is labor-intensive and requires excessive water—taking a team days to complete a job that we can handle in hours.
Harmful
Many competitors rely on sodium hypochlorite (SH), or bleach, to clean roofs. This aggressive chemical degrades the surface of TPO material, weakening seams and corroding metal fasteners. Furthermore, bleach runoff harms plants, damages nearby structures, and poses serious risks to workers and the environment.

Gentle Cleaning with Proven Results
Our proprietary solution underwent years of testing to ensure it's safe for TPO roofs. Unlike pressure washing, our low-pressure application is as gentle as a spring rain. It cleans thoroughly without compromising the welded seams or roof membrane, ensuring your roof remains in top condition and under warranty.
Eco-Friendly & Safe
Stain Erasers is safe for people, pets, plants, your property and THE PLANET. Unlike bleach, it won't harm landscaping, corrode surfaces, or pose risk to employees or nearby pedestrians. Our spray-and-walk-away method guarantees no harmful runoff into the environment.
Cost, Labor & Time Savings
Stain Erasers can clean a 70,000-square-foot roof with a two-person team in just two hours, using only about 350 gallons of water. Compare this to pressure washing, which requires a full week of work, multiple personnel, and nearly 17,000 gallons of water!
Preserve Energy Efficiency
TPO roofs are white to reflect sunlight and keep buildings cool. Organic growth turns the surface dark, potentially raising roof temperatures from 80°F to 170°F and driving up cooling costs. Our cleaning process restores your roof's reflective properties, reduces energy expenses and maintains warranties & compliance with programs who give credit for clean white roofs, like Florida Power & Light.
What To Expect
Results That Build — And Last
Weeks 2–4
You'll typically begin to see results within 2 to 4 weeks as the weather activates the treatment and growth starts breaking down.
Up To 120 Days
Full results develop over up to 120 days as the membrane returns to reflective white — a clean that lasts instead of a blast that regrows.
Guaranteed Up To A Year
Our Clean Guarantee assures your roof stays clean up to a year — and if you're not completely satisfied, we'll make it right or provide a full refund.
Protect your roof's warranty — and its white.
