Roof moss removal is needed in locations in which there is a lot of moisture in the air—and so certainly people need it here in the Northwest. All of the dampness causes fungus, mold, moss, and algae to grow quickly. Not only are fungus, mold, moss and algae an eyesore, but they reduce the life of your roof. It is more economical to prevent the fungi than to let them grow and then kill them.

Our roof moss removal method – washing – allows us to kill mold, spores, and fungus not only at the surface but also at the roots, while preserving the integrity of your tiles or shingles at the same time. Our thorough cleaning service includes:

  • Professional pressure washing. We use high water volume and low water pressure to gently clean cedar shake, tile, and metal. Our system is safe for use around your children, pets, swimming pools and plants.
  • Thorough cleaning. We will get rid of all the mold, algae, fungus, and debris.
  • Complete service. We will also clean gutters, downspouts, decks, and concrete.
  • Air blowing. We maintain and clean all surfaces and gutters with annual air blowing to get rid of fallen tree debris.

While anyone can spray water on your house, our professional roof cleaning is more complicated. Not all materials need to be pressure-washed, and some should not be washed over and over. In many cases, we can simply air-blow the debris off.

We use low pressure roof moss removal methods. Since total replacement is a very expensive alternative, this prevents damage to your tiles, shake or shingles. This method effectively eliminates the mildew and fungus growth and also kills the spores these plants grow from. By applying our chemical treatment, your house top will stay clean longer, and there will be no damage to your tiles or shingles from the use of high pressure cleaning methods.

Composition surfaces are cleaned by brushing or scraping the moss by hand, and then air blown clean. This method is used to reduce the amount of granules lost on the composition during the cleaning process.

Fungus holds moisture on top of your house. It lifts shingles and draws moisture up underneath it. This causes water to back up, producing leaks. It clogs gutters and downspouts, and produces airborne spores. When it is knocked off, it takes shingle particles with it. Plus, its appearance alone brings down property values.

Once we clean your house top with our roof moss removal system, it can be maintained by annual air blowing. There is no need to have to rewash when it has been treated properly.

The best time for roof moss removal is after the growth has been dead for a few weeks. It can damage shingles if you try to remove it while it is still alive. It will fall in your yard and may start growing there.

Dead moss that is being eliminated from the shingles will break up into a powder and not harm the shingles. How soon you can eliminate it depends on how long it has been dead, the current weather, how big a hurry you are in, and how much rain and sun have hit the roof.
