In Maryland, asphalt shingles are prone to algae, moss and lichen growth. Black algae is the most common problem and is usually the reason our customers call us out to clean their roof. If left untreated the algae will usually take over the entire roof!

.
Even major roofing manufacturers like GAF/ELK recommend having your shingles professionally cleaned. Professional roof cleaning means using the correct equipment and chemicals to gently scrub the shingles.

When hiring a pressure wash crew to clean your roof, make sure they are experienced, insured and have the proper equipment to do the job. You do not want an attempt to clean the roof using high pressure as this will surely damage the shingles and cause premature failure and shorten the life-span of your roof!

At College Student Cleaning, we use hot water, low pressure and the proper mixture of safe and biodegradable cleaners to do the job right the first time, saving you time and money!
