Pressure cleaning your home is a must in triple digit heat.

Westchester Power Washing specializes in the “low pressure” roof washing method, ensuring your shingles remain undamaged and your roof stays in good shape.  This is the best and only method approved and suggested by ARMA – American Roofing Manufacturer’s Assocation, as well as the Ownes Corning and Gaf – the leading shingles manufacturers in the world.

We outline the process over on our roof cleaning page, but we thought Westchester NY, Putnam NY, and Dutchess County NY homeowners would find this tidbit from Roof Rescue useful:

Unsightly black stains or streaks on asphalt shingles is caused by a hardy type of algae called Gloeocapsa magma. This type of algae thrives in humid and warm climates and usually appears, first, on the North slope of the roof where shade is prevalent and moisture tends to accumulate. The algae feeds on the crushed limestone that is used in asphalt shingles. Rain then spreads the algae down the roof, causing black streaks. As the algae breaks down the shingles, the granules that protect the shingle are loosened and begin to fall off. This causes the roof to deteriorate and diminishes the roof’s ability to reflect heat rays. If left untreated, the algae will reduce the life of your roof, diminish your home’s curb appeal, and increase your home cooling cost.  This roof algae can be killed and removed to restore your roofs appearance. But the right cleaners and low pressure are a must, so that damage is not done to the roof.

So true.  Many amateur roof cleaners will use a standard power washer and create a costly mess for you to clean up.  Leading shingles manufacturers emphatically state that our low pressure wash method is the best method to clean roofs, and a standard power washer should never be used in a roof cleaning.  Using too much pressure will cause granule loss and reduce the longevity of your roof by by up to 50%.

That’s too costly. Our methods are designed to eliminate black mold while preserving your most valuable asset — your home.
