Roof Moss Removal and Treatment Cost

Average 25 - 50¢ per sq ft*


Our Process: 

Step 1: We manually remove the moss using small brushes and tools.

Step 2: We clean out the gutter system and thoroughly clean up all decks and ground where debris will have fallen off the roof.

Step 3: We apply a large amount of spray treatment to ensure a 100% kill of all moss, algae, lichens and mold.

Please note: cleaning out the inside of the gutter system is a necessary step that can't be skipped. We need to ensure they are functioning well so that excess spray is able to flow down the downpipes.

Below is info on why we do not pressure wash Asphalt or Tile Roofs.


Asphalt / Fiberglass -  Water getting under and extra granule loss are two of the reasons why its a bad idea to pressure wash Asphalt. This is a quote from the Asphalt Roofing Manufacturers Association. "Caution ! High pressure washing systems for algae removal should not be used."

Clay and Concrete Tile - Pressure washing tile is actually allowed by some of the tile roof manufacturers. However, they say to a maximum PSI of 1200 and staying at least 1 foot away from the surface. I doubt that any technician washing your roof adheres to these guidelines. Another thing to consider is your neighbours home. If your houses are at all close together, they need to be warned of the monumental mess of wet moss and sandy muck that will be hitting their siding, windows and gardens. Also, in my opinion its impossible to pressure wash a tile roof and not get at least some water under the tiles. Another thing to remember is when you pressure wash a tile roof, you're not actually killing the spores so the moss and algae will grow back quicker than if you kill the root of the problem with chemical.

Cedar Shakes & Shingles

Cedar Roof Restoration - Cedar Roof Restoration is a process that includes having the ridge caps replaced as well as any failed shingles. The entire roof is cleaned with a pressure washer using low pressure and high volume. The roof is then coated with a treatment that is specifically designed for cedar and allows the shakes to breathe. We do not provide this service.
