Average Prices for Roof Cleaning 

Over 10,000 roofs in Western Washington are replaced per year due to neglect. The majority of these roofs are replaced at 40-50% of their life expectancy,according to roofcleaners.org. It’s quite common to see 20 year roofs replaced and needing repairs at 5 years in the Seattle area. All these issues can  be avoided with maintenance.

Roof Cleaning

When you purchased your roof you were given a warranty. In order for it to be valid, your roofing needs maintenance. The American Roofing Manufacturers’ Association gives a step by step guideline on what maintenance is and how it should and should not be done.

ARMA lists [2] cleaning methods that void a warranty for most roofing manufacturers. They cite granule loss as the primary reason these methods should be avoided. These methods are:

  • Power washing  any asphalt shingle roof
  • Using any form of rough agitation when removing moss.

ARMA recommends chemical treatment as their approved method for cleaning asphalt shingle roofing. They have gone as far as to list the chemical blend and ingredients to use. Seattle Roof Cleaners follows the method and instructions for roof cleaning provided by ARMA to the letter.
