Moss Preventative Treatments
Roof Cleaning & Moss Treatment Service in Whatcom County
We most commonly clean composition/asphalt shingles. The recommended cleaning method will depend on the type of debris that is on your roof. We recommend having a moss preventative treatment applied after cleaning. We use Zinc Sulfate which is the most popular moss preventative treatment and is safe on roofs- please see below for more details.
Roof Pressure Washing
Gentle pressure washing makes your roof look new and is the most popular method in the Northwest for removing moss, slime, dirt, and discoloration. 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.
Roof Air-Blow Cleaning
Air blowing 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. Our technicians are professional, highly skilled, and courteous.
Moss Preventative Treatment: Zinc sulfate
Applying moss preventative treatment in Whatcom County once a year 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.
