Roof Cleaning Myths Busted — Why Roofers Hate Us
In the world of roof maintenance, misinformation spreads faster than moss.
You’ve probably heard people say roof cleaning causes damage, isn’t worth it, or that moss is just “a bit green.” Truth is, a properly cleaned roof not only protects your home, but also adds real long-term value.
At MECS, we specialise in roof steam cleaning and softwash biocide treatments — each tailored to your roof’s specific material and condition. Let’s bust a few myths with facts.
🧠 Common Roof Cleaning Myths (And What You Actually Need to Know)
❌ Myth #1: "Pressure Washing Damages Tiles"
Not in trained hands.
The truth:
Uncontrolled high-pressure washing can damage fragile tiles — that’s true. But at MECS, we use controlled cold pressure and low-pressure steam systems, designed for deep cleans that lift moss and debris without disturbing tile structure or mortar.
Every job starts with a site assessment to choose the right method — no guessing.
❌ Myth #2: "Moss Is Harmless – It's Just Ugly"
Looks matter — but so does function.
The truth:
Moss traps moisture, spreads rapidly, and over time can weaken pointing, block gutters, and reduce the roof’s ability to drain water efficiently. It's more than cosmetic — it's protective maintenance.
❌ Myth #3: "It’ll Just Grow Back"
Not if it's done properly.
The truth:
We finish every clean with a professional biocide treatment — the same standard used by commercial contractors and housing authorities. It continues working for up to two years to prevent moss from coming back.
🏆 What Sets MECS Apart
We don’t believe in one-size-fits-all methods. We assess your roof and choose the most suitable process:
Steam cleaning for delicate surfaces or stained patches
Softwash & biocide for lasting results and safe prevention
This isn’t “just cleaning.” It’s restoration — done to premium standards.
🔐 Final Word
We’re not against roofers — in fact, many refer clients to us when cleaning is the smarter move over replacing. What we are against is misinformation that costs homeowners money, damage, and time.
