- What advice would you give a customer looking to hire a provider in your area of work?
DO NOT PRESSURE WASH YOUR ROOF. Many unqualified roof cleaners will pressure wash since its fast. This will almost certainly cause shingle damage. Look for a roof cleaner that uses brush, forced air, or soft wash for moss removal. Northern Services will use either brush method or forced air as both are easy on shingle granules. We also will apply moss treatment after every roof cleaning and clean the gutters out.
