Does your roof have a squatter? Many roofs across Brevard County and beyond are serving as hosts to the Florida roof algae of Gloeocapsa Magma – an algae with minimal nutritional needs and an ability to leave a roof looking streaky and discolored as they colonize. What are the unique characteristics of Gloeocapsa Magma? As a local roof cleaning company, we have seen this unwanted guest take up residence on many homes. Read on to learn more about what it is.
Gloeocapsa Magma has a dark pigment due to a natural dark, protective membrane that shields the organism from UV rays. This dark pigment makes the algae colony appear as dark streaks on the roof of a home. What do these uninvited guests find to eat? It turns out that the algae are able to use photosynthesis to gain carbohydrates, and they also absorb nitrates through atmospheric nitrogen. The remaining trace nutrients necessary for life they gain from dust and dirt that the wind happens to blow their way. An additional source of nutrition for the algae can be found in the calcium carbonate in asphalt shingles.
As the algae grow, they release spores from the colony. These spores hitch a ride on the wind, landing on the next available roof. In this way, the algae can turn the roofs of entire neighborhoods into streaky black structures. In fact, the spread of this algae is growing and it can be found on 80% of homes in the U.S. The most effective means of ousting this invasion is a proven soft wash roof cleaning method. Just what kind of damage can algae do and why should you consider a professional roof cleaning? Stay tuned next week for more on the effects this squatter has on your roofline!
