Why is Cleaning Your Roof Important?

Roof Cleaning

Often mistaken as mold or mildew, the black discoloration and streaks visible on many roofs across the Augusta area are actually algae. The algae forms where moisture tends to dwell on roof surfaces. The climate here in the Augusta area creates the most conducive conditions for algae growth. The most common type, gloeocapsa magma or blue green algae, protects itself from damaging ultraviolet rays by producing a dark pigmented sheath. The algae discoloration typically begins as small spots then quickly transforms into streaks on the roof plane. By the time the algae is visible, it likely has been present for several months or longer.

Algae spores are carried by the wind or by animals and can quickly spread from one rooftop to another. That is why it is common to see algae growth on rooftops throughout an affected neighborhood. The same is true for apartment or condominium complexes, townhouses or row houses. On highly reflective or “cool” roofs, algae will undoubtedly have a negative impact on the long-term effectiveness of these roof systems. That is why it is important to address an algae problem as soon as possible.

Algae and moss growth on roofs, at a minimum, is an unsightly nuisance. Moss build-up can lead to roof damage or shingle blow-off if left unchecked. Keeping branches trimmed back from the roof and removing any debris that begins to accumulate should be part of a regular roof maintenance program.
