Is there Black Roof Algae on your Tampa Roof ?
Algae growth on roofs has reached unprecedented levels in many parts of Florida today. It creates a dull and dirty appearance which can reduce the value of your Florida home. Roofing materials like tiles, slates, cement and all become dull and weakened by Algae and Black Mold growth. Even the thinnest layer of Algae and Black Mold is a problem because it acts like a sponge, absorbing water, which increases the weight and stress on your Florida roof, shortening its productive life. Heat damage is another problem when there is Algae and Black Mold on your roof as it can push the tiles up and crack them.
Much of Tampa Florida’s unprecedented spread of roof Algae and Black Mold can be traced to the Clean Air Act which reduced the output of Sulphur (poisonous to moss) into the atmosphere via coal and fossil burning power stations, or domestic fires and unleaded fuel. Roof Algae which would have been previously killed off by this sulphur in the Florida atmosphere now requires direct action through commercial roof repair and maintenance like regular roof cleaning to prevent it from spreading.
Roof cleaning measures such as pressure washing can remove or roughen the surface of the roofing material, reducing the intended productive life of the roof. At best it is a messy, temporary solution which would need to be repeated frequently. This sort of procedure also does nothing to kill the spores that created the Algae and Black Mold.
suggests that no pressure roof cleaning process not only cleans your roof safely, it also kills this Algae, so it doesn’t grow back so fast!
