Aquidneck Island Roof Cleaning, (AIRC) utilizes a safe bio-degradable no-pressure roof and exterior cleaning solution, that kills the algae, moss, fungus, bacteria and/or lichen dead, right down to the root. Many roofs become severely damaged and end up needing to be replaced, in as little as 3 - 6 years. Most of the time, all they need is a good professional cleaning and cleaned again when the black streaks start to reappear. Sun exposure and proper cleaning affects the length of time between the reocurrence of algae, fungus, bacteria and lichen. Most customers are unaware that roof shingle manufacturer's can void the roof shingle warranty, due to pressure washer damage, while still requiring, that a roof be properly cleaned. Soft washing cleaning process is an effective, affordable and acceptable roof and exterior cleaning process.
