If your roof has black ugly streaks, or green moss growing from it, it mght be time for a roof cleaning service. Those black streaks are actualy a form of algae that consume the ingredients used to manufacture your roof. Over time, the algae can green moss can cause roof damage, requiring premature replacement.
Our non-pressure method uses a biodegradable solution that kills the algae and moss dead in its tracks, and restores the original appearance of your roof, typically the same day it was performed. Non- Pressure means just that…. No high pressure is EVER used on your roof. The pressure used to apply the soaps is comparable to the water pressure coming from a garden hose. It is nearly impossible to cause damage with that low of a pressure rating. The green moss bunches you see will actually die instantly and turn white and brown. We DO NOT remove them! They literally have a shallow root system that has grown and attached itself into your shingles, and removing them would be comparable to removing a band-aid or a scab on your arm, and could be considered “painful” to your roof. What does happen, is that over the course of the next few days after the roof wash, the root system withers and the moss will simply fall off with the next rainstorm, without causing damage to the roof. This is the safest way to clean a roof at this time, and is also the most effective. As a matter of fact, the ARMA (Asphalt Roofing Manufacturer Association) recommends the cleaning methods that we use, as well as the PWRA (Pressure Washing Resource Association).
