Why is the mold thriving on my head?
Pressure Cleaning Mold

In 1976, shingle manufacturers changed the composition by adding limestone as filler. Since then, nearly every roof has been reinstalled and strangely an growth has started to occur on the roof tops. This growth is commonly called roof algae or roof mold. Now when the wind carries roof algae, it gets deposited to the surface of your roof and the creatures find a good deposit of limestone to feed on but this is not all. The roof mold needs two more things in order to survive; sunlight and moisture and you know very well that the roof top is the ideal place for these conditions to be satisfied. So the party on your roof has been going on for quite some time.

Roof algae are smaller than a pen tip hence you may not be able to notice them from ground. However, well fed algae start to grow and spread and are easily noticeable. This is not al, these algae invite other friends that live on organic waste products of bacteria. So when you get millions of algae on the roof, the mildew, mold and fungus join the show.

In the past there were less chances of roof infestation unless leaves and other debris accumulated to serve as a fodder for them. But now the limestone serves as an inorganic food on which bacteria feed which creates ‘organic algae waste’ which makes for a feast of fungus food! Besides tarnishing the appearance of the roof, the rood mold brings in many other disadvantages such as:

  • Reduce shingle life
  • Create neighborhood eyesore
  •  Increased air conditioning bills
  •  Reduce Property Values
  • Allow mold to work its way inside
  •  Introduce Risk of Bird born Bacteria
