Gentle Roof Pressure Washing for Moss, Algae and Black Slime in Whatcom County
Gentle pressure washing makes your roof look new and is the most popular method in the Northwest for removing all contaminants including moss, slime, dirt, and discoloration. This is our standard cleaning method and the method used to clean the roofs on our "photos" page. We always include gutter cleaning for free. This method is safe for your roof and supported by shingle manufacturers. We take great care to ensure the cleanliness and safety of your roof.
Air blowing with a backpack leaf blower is an effective method to remove leaves, pine needles, and branches. Getting your roof blown off will remove debris, allow water to properly flow into your gutters and will make your home look nice. Please specifically mention that you would like this method in your inquiry as it is much less expensive than our standard roof washing.
Moss Preventative Treatment: Zinc sulfate
Applying moss preventative treatment once a year in Whatcom County will keep your roof moss free. Reapply twice a year for shaded areas. After a roof cleaning, we can apply 10-20 pounds of zinc sulfate powder for $60-$100 (This includes us supplying the product). We apply about two times the amount that manufacturers recommend to ensure that your roof is protected until the next treatment. We spread the treatment in 1-2 lines on each section of roofing (see photos for examples). Please note, we cannot guarantee the results of the treatment. We do not advise that you use the treatment as a means to kill or remove existing moss. If your roof has moss and algae currently growing on it, it will need a roof cleaning.
Zinc sulfate is the most popular treatment on the market to prevent moss and will not damage your roofing material. Zinc Sulfate is commonly branded as Corry's Moss B Ware or Lilly Miller's Moss Out and is found in most hardware store.
