#3 Application of soft wash solution using low pressure truck mounted system to Instantly kill all moss, algae, and or lichen immediately with a 100% kill rate.  This service comes with a 5 Year “No New Moss Warranty”.   The moss will turn white and or brown immediately after soft wash is applied.  The moss will slowly dissolve and deteriorate over time with wind, rain and the outside elements.  This process usually takes 30-90 days. Our cleaning solution will eliminate all black/green algae stains (Gloeocapsa Magma) at the time of application. Antifungal agent remains on the roof after our treatment to limit re-growth of these organisms. (pictured below)

Five Year No Green Roof Moss Warranty

*Warranty information:  If moss regrows after premium roof care service we will re-spray at no charge.  In order to qualify for a warranty the moss must be green and alive.  Moss that is dead from soft washing will not qualify for warranty respray.  In some cases the dead moss takes more then 90 days to fall off.  If this is the case we can offer you a discounted respray that will help dissolve the anchor of the dead moss to help the process.

#4 To complete the service our technicians will perform a complete ground clean up and final walk through of the project. 

Additional information on our soft wash process:Algae, moss and mold can shorten the lifespan of any roof and detract from your homes curb appeal. A chemical treatment (soft wash) that kills these forms of fungus on contact is the safest way to eradicate these destructive microorganisms.

Our soft wash solution is environmentally safe, biodegradable solution applied at LOW PRESSURE to insure a 100% kill ratio of algae, mold, moss, mildew and lichens. Our Soft Wash treatment is recommended by the ARMA (Asphalt Roofing Manufacturers Association) and GAF, North America’s largest shingle manufacturer. Asphalt Roofing Manufacturers Association Algae and Moss Information Link

Our cleaning solution will eliminate all black/green algae stains (Gloeocapsa Magma) at the time of application. Antifungal agent remains on the roof after our treatment to limit re-growth of these organisms.

Roof Moss Has No Chance With Chinook Services Soft Wash

Moss takes several years to attach and grow, therefore, forcing them to detach will cause damage to the shingles.

Removing moss instantly by brushing, using high volume compressed air, scraping or pressure washing should never be performed and will void manufacturers’ warranties if used.  Roofs that are improperly cleaned can look great when done, but the unseen damage caused will limit the roof’s lifetime rapidly.  Additionally, forcing alive moss from roofs is messy.  Alive moss will fall into your lawn, flower beds, walkways, and other areas where you do not want it to grow and spread.  This is not the case with Chinook Services, we kill 100% of the moss.

Our soft wash solution is very valuable and safe for your roof.  Please call or email our office for more details if needed.
