🏢 Commercial Flat Roof Cleaning:
What’s Growing Up There Could Cost You Thousands
Out of sight. Out of mind.
That’s how most commercial flat roofs end up — until the leaks start… or the drainage fails… or mold shows up in tenant units.
At Prestige Pressure Washing, we’ve seen it all:
🌿 Algae colonies the size of a garden
🌧️ Water ponding that eats into roofing seams
🚫 Clogged rooftop drains that lead to structural damage
If your building has a flat roof — especially TPO, EPDM, or built-up roofing — now is the time to clean it, inspect it, and protect it before fall rain and winter weather make small problems worse.
🚨 Here’s What Could Be Growing on Your Roof Right Now:
Black algae that feed on limestone and accelerate membrane decay
Moss and lichen that retain moisture and lift seams
Mildew and grime that reduce reflectivity and increase heat absorption
Organic debris clogging roof drains and scuppers
One heavy rain + a clogged drain = interior water damage and emergency calls.
🧼 What Is a Flat Roof Soft Wash?
A soft wash is a low-pressure cleaning method using biodegradable, roofing-safe detergents to:
✅ Break down organic buildup
✅ Remove grime and discoloration
✅ Restore reflectivity
✅ Preserve your manufacturer warranty
✅ Extend the lifespan of your roof
Unlike pressure washing, soft washing won’t damage the membrane or void your roof system coverage.
