Gutter cleaning and Christmas light installers in Bellingham

This is one of the most common questions we get as professional roof cleaners! That leftover moss should appear yellow/white in color, that means it is dead. The roots have been released from the shingle. It will turn to dust and blow away naturally in 3-6 months. We ask for you to wait 6 months before calling us for a warranty retreat. That is how long it usually takes to actualize 100% of the results from the treatment. This process is the safest way to clean a roof and protect one of the largest investments on your home.

Soft washing is best compared to cleaning your car. You have to use soap, not pressure to clean or sanitize it. Soft washing applies the same principles. A detergent is used to lift staining which allows for a low pressure rinse. Soft washing is more effective and efficient than conventional pressure washing. It cleans, santizes, and brightens your property without having to use high damaging pressure.

We require a card on file. In the event you are unable to do so we require a check prepared for us to be collected on-site upon completion of your service. Payments are due upon completion of the work.
