What affects the cost of minor roof soft washing?
Roof area and pitch
Square footage plus how steep the roof is determine the time and safety setup required.
Soft-wash method
Shingles are cleaned with low pressure and a cleaning solution — pressure washing a roof damages the granules.
Growth type and runoff protection
Heavy black algae or moss needs longer dwell time, and landscaping below has to be rinsed and protected.
