Roof Moss Removal and Treatment

Additional Information

Our Roof Moss Removal and Treatment Process includes:

For several years we have used a Zinc alternative for treating moss. (It's no extra charge and is a fish friendly alternative that is just as effective as the environmentally toxic zinc)

  1. We first remove the large clumps of moss with a gentle scrape of the 3 tab, composite, asphalt, fiberglass, or laminated shingles. (removing the moss that stands around a centimeter or taller)
  2. Then we blow the loose debris off the roof and eaves.
  3. We then apply the moss treatment to the roof’s surface (valleys, eaves, hips and ridges). The remaining moss will dehydrate and become brittle, eroding off the roof, making the shingles look nice again. This terminates, eliminates, and inhibits the future growth of moss and the spores for approximately 12 months to even a few years. Averaging 1.5 to 2 years depending on the tree shade, exposure to the sun, and harshness of the winter weather.
  4. We then clean the gutters and tidy up the yard. (Gutters cleaning has a separate line item in the quote)
  5. This treatment will not hurt the plants or pets around the house or the fish in nearby lakes and streams.
  6. Once it rains you will see discoloring after about 10-14 days and then the process is on it's way to start the treating.
  7. Allow about 8-13 weeks from the first rain to notice that all the moss and treatment is gone and your roof shingles looks great. (In the Summer months it works just as well but can take longer because of less rain.)


*Moss removal and treatment can be done anytime of the year and in most cases should be done annually or every other year. Gutter cleaning is needed along with the moss removal and the treatment process. Late fall (November on) is a great time to schedule moss removal and the treatment since your gutters need cleaning at that time of year from the last of the leaves falling.

  5. We will e-mail you a detailed and clear proposal with estimated pricing.
