What is Soft Roof Washing?

Soft roof washing is our safe, effective low pressure cleaning method. It allows us to clean and sanitize your roof from the safety of the ground or a platform using low pressure equipment that effectively cleans and sanitizes your roof (and home exterior) with our eco-friendly soft washing cleaning product.

Our soft roof washing method kills, removes and prevents organic growth and black stains associated with mold, mildew, lichen, pollen, algae, moss and fungi growth.

Soft wash treatments focus on the root cause of the mold and mildew growths while killing the spores without damaging property or harming people or the environment.

Studies have shown, soft roof washing is the fastest and most effective hard surface cleaning method available. Soft roof washing can keep surfaces clean for up to 5 years depending on weather conditions and property location.

Our soft wash roof cleaning process is fully approved by all shingles manufacturers including ARMA (Asphalt Roofing Manufacturers Association).

The soft-wash process is also recommended by all insurance companies. All products we use to clean the roof and exterior of your home are 100% biodegradable. Having your roof cleaned is recognized as general maintenance.

So, how is soft roof washing better and different than high pressure roof washing?

With high pressure roof washing, massive amounts of water pressure is used to remove mold, algae, lichen, moss, and other contaminants. High pressure washing can give you immediate results that look good but this may last for a short period of time. Pressure washing blasts dirt and grime. Unfortunately, this usually causes permanent and irreversible damage. Besides damaging homes and landscapes, high pressure washing is known to spread spores onto other surfaces therefore spreading the mold, mildew, lichens, moss and fungus into air you breathe. This ultimately means your roof, home and other surfaces will need to be cleaned sooner and mold will appear worse than before thus making high pressure roof washing even more expensive than soft roof washing.

We are so sure of our soft roof washing process, we provide our customers with a 5 Year Limited Streak-Free roof washing guarantee.

But first you need to know what you’re dealing with.

Why Wash Your Roof?

Black streaks and stains on the roof are usually more than that. Algae, moss, or lichen feed on limestone in the roof shingles and continue to multiply creating a roof full of unsightly streaks. The algae dislodges the protective granules and when left untreated, this algae can prematurely degrade and cause roof failure. Additionally, it can expose residents to other potential health concerns.


With our proven soft roof washing method, we do not use traditional power washing. Instead, we use a safe and effective cleaner than kills mold instantly. We will gently spray your roof removing years of growth bringing your Westchester home back to its original look.

This is the ONLY roof cleaning method approved by Asphalt Roofing Manufacturing Association and the largest shingle producers.

Our proven process removes roof algae quickly and brings back the curb appeal of a new roof once more. Roof washing is among our specialties, and our experience safeguards you against the damage-prone methods of less experienced competitors. We understand that the soft-wash method protects your roof against unsafe cleaning methods and your wallet against a higher electric bill.

As light-colored asphalt roofs turn dark black with algae, they incubate more heat. This can push your central air conditioner to work harder than it should. (Experts estimate your roof would be 20% hotter with black algae forming on its surface.)

That’s where Westchester Power Washing comes in.
