Got those nasty black streaks slowly taking over your roof?
You do NOT need a new roof because of it! If your asphalt shingle roof is still structurally sound, it can be cleaned safely and properly. It’s the EASIEST way to make your roof look new, without actually buying a new roof!
SO, what is it?
The black roof streaks that are attacking many homes in the Northern Virginia is “Gleocapsa-Magma” . It’s a airborne algae that feeds on the limestone in the asphalt shingle. Many shingles have a protective coating to prevent algae when manufactured, but that coating wears off in 3-7 years.
What does it do?
Gleocapsa-Magma, like other types of organic growth you may have on your roof, feeds on whatever it’s on. Overtime, if not addressed, the algae can eat through the shingle causing premature wear. That’s when the shingles will need to be replaced.
How is it cleaned?
Asphalt shingles are fragile, due to their composition of fine granules, so they require a gentle cleaning. Pressure washing is not gentle on shingles. What we do at Patriot Pro Clean is a very low pressure chemical based cleaning.
Two major advantages of low-pressure roof cleaning
- Low pressure is used to avoid the premature wear of blowing off granules
- Since the cleaning is chemical based, all organic growth on the surface is eliminated. With pressure washing, traces of the organic growth is still alive and well on the shingle.
(Not to mention, our cleaning method is the ONLY method approved by the Asphalt Roofing Manufacturer’s Association – ARMA.)

*Note: In some cases, it is a great time to have your gutters cleaned out as well, allowing proper flow into downspouts.*
