This picture of this roof that we cleaned illustrates what we do. We get your roof clean that day and spray a treatment for prevention of future growth! Dont let anyone just kill it simply by spraying as dead moss still retains water like live moss and it will come back to life in a few months. Get it done right that same day! with pictures taken of every job.
JNR Industries (503-432-9093) is BY FAR your best option for roof cleaning and maintenance.
The power washing method begins by coating the entire moss affected area of the roof with our roof cleaning solution; let the product go to work on the roots of the moss for at least 15-20 minutes before starting to clean the roof, it is ok if the product dries in this method because the water will reactivate the cleaning product when you rinse it with the pressure washer.
