Should you call a roofing contractor or Westchester Power Washing?

 

Most roof contractors do not want you to know that your dirty roof shingles are dirty and need to be cleaned, not replaced. If you see black streaks on your roof, mold, mildew, lichens, or moss, call Westchester Power Washing at 914-490-8138.

More than likely, your dirty roof needs to be soft-washed. Soft washing removes black streaks, mold, mildew, lichens, moss, and of course, dirt from your roof.

Homeowners think a dirty roof needs to be replaced. If you call a roofing contractor, they will likely tell you to replace your roof. Why? Roof contractors make money replacing roofs. Furthermore, roof replacement can cost as much as ten times the price of having your roof cleaned. If your roof is less than 25 years old, you may just need to have your roof professionally shampooed and cleaned.

Black streaks are caused by roof algae. The technical term for roof algae that cause the black streaks on your roof is Gloeocapsa Magma. Algae feed on the crushed limestone used in asphalt shingles. As rain washes down your roof, it spreads algae down your roof causing the black streaks you see. Black streaks cause shingles to fail prematurely by not preventing the shingles from reflecting heat properly.

Research has shown 50% of dirty roofs in New York are replaced because of black streaks not because they are damaged.

 

Unfortunately, when homeowners see a dirty roof, they think it is time to replace their roof. This is usually not true. Research has shown more than half the roofs replaced in Westchester County, NY were replaced because of how they look and not their condition. Therefore, more than 50% of roofs need to be professionally washed, not replaced. In fact, this means, people who replace their roofs have simply wasted their money.

Roofs in Westchester, Putnam, and Dutchess County, New York experience a lot of humidity, rain, and snow. This moisture promotes algae to grow on the roof. The algae create black streaks and the roof looks dirty, old, and damaged. As stated before, this is just a dirty roof not a roof in need of replacement.

How do I know when my dirty roof needs to be washed or replaced?

 

Just as mold and mildew grow on your vinyl siding, wind-blown algae lands and grows on your slate, cedar, asphalt, and shingle roof. Remember, your home’s exterior just like the interior needs to be washed and cleaned. Therefore, when your house, patio, deck, roof, siding, fence, outdoor furniture gets dirty, pressure washing saves you money being cleaning not replacing.

Most roof contractors do not know the difference between a dirty roof with algae and black streaks versus a roof in need of repair or replacement. Roof contractors sell roofs, not clean roofs. Also, some roof contracting companies do not know the roof is dirty because they are not educated in roof maintenance which includes roof washing.

If you are thinking about replacing your roof because it is dirty, you see black streaks or your roof looks faded, call Westchester Power Washing first at 914-490-8138. We will take a look at your roof and give you a FREE roof cleaning and washing estimate.

What are the signs of a dirty roof that needs to be replaced?

 

To being with, never use a pressure washer on an asphalt, shingle, or slate roof. A pressure washer will damage the granules on your shingles and lessen your roof’s life and longevity.
