Satisfaction Guarantee

We don’t have a guarantee per se, but we do make sure the moss gets removed. The completed process can take 2-3 months depending on the weather. What I tell customers that are concerned, “If the moss isn’t dead and mostly gone to call in after a 2-3 months.  We will go out the next time we are in the area and make sure you are satisfied.” We service hundreds of roofs a year and we go out and check on maybe 1-5. As for how long the treatment lasts is depended on several things…

  • neighbors spores blowing to your house
  • north and east sides doesn’t get much sun
  • tree shade
  • weather from one year to the next


Most houses get 1-3 years worth of freedom from moss but some may need to do a couple years of treatments to get it back in control and looking nearly new again. Also the maintenance in years to come can be less expensive if the moss is minimal.

*Roof Moss Treatment – We scrap taller than half-inch moss on asphalt composite tiles, then blow loose debris off of the roof, and finish by spreading zinc or alternative powder that moves down the roof with future rain. The remaining moss will dehydrate and become brittle, eroding off the roof. This process can take up to a 8-13 weeks when we are in a rainy season and longer while it is dry, but you will see that the moss is discoloring, dehydrated, and died after about 10 days to a couple weeks of the first rain. * We don’t treat terra-cotta or cedar shake roofs.
