Chemical Roof Cleaning

Soft-washing involves the use of chemicals to clean roofs. This method is employed to lessen the amount of damage caused by power-washing. Power-washing on average removes 3-4 layers of granules per cleaning . A roof is known by its years of life:

  •  A 20 year roof has 20 layers of granules.
  •  A 50 year roof has 50 layers of granules.

The soft-wash method when used properly is far more beneficial to roofing substrate then power-washing. No granule loss happens when chemicals are sprayed on your  roofing. Additional benefits include:

  • The elimination of all moss spores that cause moss to grow in the first place.
  • A much longer lasting finished product; on average the process lasts 2-3 years

ARMA [Asphalt Roof Manufacturers Association] recommends soft-wash cleaning for proper roof maintenance. ARMA is the association that governs the making of asphalt shingle roofing. They are the leaders in the industry in the production and proper cleaning methods of roofing materials.

The difference in the finished look of the product : power-washing versus chemical cleaning is nearly indistinguishable, when the proper chemicals are used. A soft wash roof cleaning company generally use a few standard chemical products:

  • TSP [trisodium phosphate]. Known for its ability to remove algae and rust stains
  • Sodium Hydrochloride 10% or higher: known for its ability to kill moss and clean shingle.
  • Borax Lo: A soap like product known to aggressively kill weeds, spores and moss residual.
  • Isopropyl Alcohol: used when aggressive moss has been growing for long periods of time.
  • Surfactant:  used to slow the mixtures path down to the gutter line.

When mixed properly these chemicals generate a long lasting safe products to roofing material. These chemicals are not readily available to the average consumer and the mixtures of this chemical call for exact amounts for a strong enough product. The procedure of soft wash roof cleaning in Seattle is best left to a professional roof cleaning company.
