Yes. Pressure washing can be very damaging to almost any kind of roof. Your roofing manufacturer could void your roof warranty if a pressure washer is used to clean it. That's why we designed a very low pressure treatment process that ensures no damage and is 100% backed by the manufacturer!

Our roof cleaning process involves a light sweep of large moss, and a blowoff of loose debris. We then spray a cleaning mixture (pressure of a garden hose) that sanitizes all moss and algae on the roof. The rain and wind will wash/blow the dead remaining moss particles off your roof in a few short weeks after. No Damage = Happy Roof! If you have a metal roof, we will wash it clean with low pressure the same day. If you have a tile roof and want an instant clean, we have the option to pressure wash on specific scoped projects. Feel free to reach out and inquire.

There are a couple of things to consider such as if you live in an area that causes your roof to be more susceptible to discoloring or algae deposits. The price essentially depends on how much SQF of work is needed and what type of roof you have, but rest assured we never carry out any work without you knowing the final price. Give us a call and we will be more than happy to talk with you to give you a detailed and precise quote for your cleaning project!

After your roof treatment process on Asphalt and Tile roofs, you may notice some dead white moss. This is normal as we intentionally do not remove 100% of the moss. This would require pressure washing or using a wire scraper and both of these are very harmful. Instead we use a light broom technique to agitate the loose moss, then we spray our solution that kills off all leftover growth.
