Should you call a roof contractor or a roof cleaning company to clean your Katonah slate roof?

Wondering if you call a roofing or roof washing company when your roof is dirty? Or if your roof has black streaks, mold, mildew, lichens or moss. The answer will surprise you. 

Many people call the local roofing company or roof contractor when they notice their roof needs cleaning. But, this is not the best choice. Roof contractors and roofing companies make money installing and replacing roofs. Therefore, slate, shingle and asphalt roof replacement is expensive and profitable for roofers. As a result, some will advise you to replace your roof or sections of your slate, asphalt or shingle roof. 

Furthermore, a dirty roof does not need to be replaced. A dirty roof  needs to be professionally cleaned. Replacing your slate, shingle or asphalt roof can cost thousands of dollars more than a roof shampoo or soft roof wash by Westchester Power Washing.

If you notice your roof is dirty, the best person to call is Peter Salotto with Westchester Power Washing  914-490-8138. The call is free and Peter give you free roof cleaning estimates and quotes.

What is Residential/ House Soft Washing?

Residential soft washing is the safest and best low pressure cleaning method. Soft washing professionally cleans and sanitizes your home using low pressure equipment with our eco-friendly soft washing cleaning product.

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

Soft washing treats root cause of the mold and mildew growths by killing the bacteria and fungus spores without damaging your home, harming people, pets or the environment.

In addition, soft washing is the fastest and most effective home exterior and roof cleaning method available. Also, soft washing keeps your home exterior clean longer. In addition, we guarantee our soft roof washing technique will keep your roof black streak free for up to 5 years.

Westchester Power Washing’s soft-wash process is recommended by all insurance companies. All products we use to clean your roof and home exterior are 100% biodegradable.


To begin with, we use a power washer to soft wash your home and roof. This is the same power washer that is used to high pressure wash driveways, decks, patios and walkways. So, the difference is not the equipment, it is the nozzle.

The nozzle we use regulates the amount of water pressure. To soft wash, we use very low water pressure. This eliminates the potential for your home or roof to be damaged.

With high pressure washing, massive amounts of water pressure is used. High pressure washing can give you immediate results that look good but this may last for a short period of time.

High pressure washing blasts dirt and grime. Unfortunately, this usually causes permanent and irreversible damage to your roof, siding, home, patio, deck and landscape.

High pressure washing is known to spread spores onto other surfaces therefore spreading the mold, mildew, lichens, moss and fungus into air you breathe. Therefore, your roof, home and other surfaces will need to be cleaned sooner and mold will appear worse than before thus making high pressure washing even more expensive than soft washing.

Soft washing advantages versus high pressure washing:

Uses less water
Longer lasting results
Little noise
Safe for all known building materials
More cost effective
Leaves surfaces cleaner(100 % kill of mold and bacteria)
Kills spores and mold on contact
Does not damage the surface
Does not exaggerate weathering effect
Leaves home exterior and roof 100% sterilized
