When it comes to roof cleaning, you’ve probably heard of pressure washing, zinc powder, and soft washing. But not all methods are safe or effective. Here’s the truth:
Pressure Washing
Pressure washing uses high-force water to blast away moss and debris. While it can make a roof look clean right away, it often:
-
Strips protective granules from shingles
-
Forces water under shingles, risking leaks
-
Shortens the lifespan of your roof
-
Can even void your manufacturer’s warranty
It’s a quick fix that usually causes long-term damage.
Zinc Powder
Zinc powder is sprinkled across the roof so rainwater can spread it to slow moss growth. But it has big drawbacks:
-
Takes months to show results
-
Only works where water runs — leaving dry spots untreated
-
Doesn’t fully kill moss or algae at the root
-
Washes away after heavy rains and needs frequent reapplication
It’s more of a temporary “band-aid” than a true cleaning method.
Soft Washing (The Best Choice)
Soft washing is a low-pressure, manufacturer-approved method that safely cleans and protects your roof. It:
-
Kills moss, algae, and bacteria at the root
-
Protects shingles instead of stripping them
-
Delivers results that last for years, not months
-
Is eco-friendly and safe when applied correctly
Even the Asphalt Roofing Manufacturers Association (ARMA) recommends soft washing as the safest way to clean and maintain asphalt roofing systems.
