Don Parker noticed black stuff growing on his business roof one summer day and was afraid that his building had been infested with black mold. Since Don ran a restaurant business, this development did not make him happy, but actually filled him with dread. After consulting with a commercial roofer, Dan was told that the black stuff growing on his roof was not mold, but a form of algae that could be cleaned. He hired a roofing company to clean his roof on their advice, given that there are several ways algae can be detrimental.

Your commercial roofer in Ft. Mill, SC may, at some point after an inspection, inform you that you have black algae growing on your roof and that it needs to be cleaned. It is important that you have it cleaned as soon as possible. Not only does algae detract from your roof’s appearance, but it can also continue to grow in humid weather or every time it rains and ultimately cause damage to your structure.

One of the primary problems algae causes is that it directly impacts your building’s energy efficiency. When a roof is covered with algae, the roof will not properly reflect the sun’s heat. This has a direct effect on cooling costs in the summer. Instead of reflecting the heat, your roof will begin to absorb it, filling your attic space and causing your air conditioner to kick in overtime.

Parker knew that his energy costs were more than he had estimated, and that it did tend to be hotter more often in his place of business (requiring him to run the air conditioner more often), and now he had an explanation. “I mostly didn’t like it because of how it made my building look,” he said. “But those other factors also played a role in my decision to buy a whole new roof system for my business.”

If a lot of algae has not yet developed on your structure, it may be possible to have it cleaned. But this can become costly over time, as well, if the algae continues to come back and re-infest your roof. If this is the case, you may want to consult with your commercial roofer in Ft. Mill, SC about a full inspection to get to the source of the problem. Algae usually thrives in the limestone that is part of the asphalt in your roofing tiles. A commercial roofer may be able to suggest alternatives, including roof replacement, in order to get rid of the problem.
