Whether your roof is young or old, when you see black stuff on it, chances are you are looking at algae, namely, Gloeocapsa Magma, a fungus that feeds on the crushed limestone used in the asphalt shingles of your roof. Gloeocapsa Magma is carried onto your roof by the wind, and the rain spreads the algae down the roof causing the all too familiar black streaks. Rain adds to the algae’s growth.

Ugly, yes, but even worse, dangerous and costly. Gleocapsa Magma often referred to as “black stuff on your roof” can prevent your roof from reflecting the sun’s heat. This can have a devastating effect on your cooling cost. As your roof fails to radiate heat, your attic catches the heat storing it at the top of your home. Your AC bill skyrockets as you try to account for the heat in your house.

Unfortunately cleaning your roof cannot repair a broken roof, so how do you know if you should replace it? Cleaning your roof may be a solution and is certainly a method you should explore, however, if the algae continues to return and the heat continues to rise, it may be time to consult a roofing expert.

Indications that it may be time to replace your roof include:

  • Shingle granules in your rain gutters
  • Thin shingles
  • Shingles falling off the roof
  • Deteriorating or crumbling shingles
  • Wavy or warping shingles
  • Shingles curling up in the corners
  • A roof older than 10 years

Are you embarrassed by the way your roof looks? Do you suffer from extreme heat in your home and costly AC bills? Have you attempted to clean the black stuff off your roof but it simply returns? If so, you may have a larger issue at hand then you may think.
