Safe & Effective
Roof Moss Treating or Cleaning done properly can be a Safe and effective way to extend the life of your roof while helping keeping your house looking in top shape. We recommend the safest gentlest option to clean-treat your roof.
Because of the fragile nature of the small rocks coating this kind of roof we offer a treatment only option with a light scrape. The scraping is only to pop off moss 1/2 inch or greater in height, the mechanical action needed to remove moss would also removes the roofing granules. For this option w e start with the light scrape, then blow off the roof, clean out the gutters, and lastly apply a Zinc Sulfate treatment to kill moss. We clean the gutters either by hand or blowing, and prefer blowing when possible as it is a little more thorough and can save you money if debris can be blown into beds and bushes- more likely when debris is dry and or you have fascia board behind the gutters. The Zinc treatment is in the form of a powder that washes down over the moss within the next few rains and completely disappears after it treats the moss. Then each year as you clean your gutters another zinc treatment can be applied if needed to keep the growth from coming back, without the need for scraping or blowing the moss. The Zinc treatment we us is the standard treatment for roofs and lasts from 6 months - 5 years, or 2-3 years for the average house. The Average size roof in 2010 was $250 with an average range of $185-300 for this option but can be more if you have a large or very mossy house, with follow ups less and if done with another service like gutters very reasonable.
