How We Clean Roofs & Why Oxygen Bleach (Sodium Percarbonate) Works So Well
One of the most common questions we get after cleaning thousands of roofs is:
"What’s your roof cleaning process, and how does oxygen bleach actually work?"
Great question—let’s break it down!

Step 1: The Power of Sodium Percarbonate (Oxygen Bleach)
Sodium percarbonate (Na₂CO₃·1.5H₂O₂) is a solid, eco-friendly bleach that, when mixed with water, releases hydrogen peroxide (H₂O₂) and sodium carbonate (a mild alkali).
✅ Why It’s Perfect for Roof Cleaning:
- Kills Algae, Moss, & Lichen – The hydrogen peroxide oxidizes and destroys organic growth at the cellular level.
- Non-Corrosive & Safe – Unlike chlorine bleach (sodium hypochlorite), it won’t harm plants, metal, or roofing materials.
- No Harmful Residues – Breaks down into oxygen, water, and soda ash, leaving no toxic traces.
📌 Pro Tip: You can even apply the **dry powder** directly to a damp roof, then spray with water to activate it—great for **tankless soft washing!**

Step 2: Our Roof Cleaning Process
We use a low-pressure soft wash system to safely remove stains without damaging shingles. Here’s how it works:
1. Inspection – We assess the roof for moss, algae (black streaks), lichen, or heavy debris.
2. Application – Our sodium percarbonate mix is sprayed evenly across the roof, soaking into the growth.
3. Dwell Time– The solution sits for **15-30 minutes**, allowing the hydrogen peroxide to penetrate and kill organisms.
4. Gentle Rinse (If Needed) – Most roofs don’t require rinsing, but heavy buildup may need a light wash-off.
5. Preventative Treatment (Optional) – We can apply a zinc or copper-based treatment to slow regrowth.
