We offer a variety of roof cleaning methods, but most customers with composition roofs are looking for a roof soft-washing which removes unsightly contaminates like moss, black staining and debris (gutters are always included for free). This typically costs $350-$650. It will cost less if you are only looking for a roof blow-off or gutter cleaning. Larger, steeper or differing material roofs will likely cost more.
Roof cleaning is important for the aesthetics of your home, but more importantly it prevents problems like moss rooting, roof leaking from improper water shedding, and moisture build up. We clean all roof types including asphalt/composition, metal, cedar shake, slate and tile.

Our staple roof cleaning method for moss and algae removal is referred to as "soft washing". This is the industry standard roof cleaning method which is recommended by the Asphalt Roofing Manufacturers Association (ARMA). This is a no-pressure process in which we lightly broom off large clumps of moss before spraying a biodegradable solution onto the roof that instantly kills all organic growth. Remaining moss turns whitish-yellow and will disintegrate off of the roof within 2-5 months or sooner, leaving the roof looking like-new. Results are completely guaranteed.
Pairing a roof blow-off with a gutter cleaning is a much less expensive option if you are not in need of moss, algae, lichen, or slime removal. This method will remove 95% or more of loose debris from the roof, but will not remove moss. Please specify this method in your inquiry.
We offer moss preventative treatments as an inexpensive way to prevent moss from growing on your roof in the first place. This will not kill or remove existing moss and algae (a soft wash roof cleaning is necessary for that). Moss prevention typically cost $60-$140 to have this powder applied to the ridges of the roof. It will wash down the roof during the following rains and can be applied rain or shine. We recommend applying this once per year to kill micro-organisms before you start noticing any moss.
