Dirty roof? Should you call a roofing contractor or Westchester Power Washing?

Most roof contractors do not want you to know that your dirty roof shingles need to be cleaned, not replaced. If you see black streaks on your roof, mold, mildew, lichens or moss, more than likely, your dirty roof needs to be soft-washed. Soft washing removes black streaks, mold, mildew, lichens, and moss 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 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 that 50% of dirty roofs are wrongly replaced because of black streaks not because of roof damage.

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 of 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 the 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.
