Have you looked at your roof recently and wondered, what is going on, our roof isn’t that old but it just looks aweful. Many people just think it is dirty or the nearby trees have stained it. While that might be part of the problem, most of the time it is Gloeocapsa Magma (, an airborne bacteria that is feeding on your roof. Fiberglass shingles (the most commonly seen amongst today’s residential homes) are made with limestone as a filler (in the asphalt). These shingles hold moisture and organic “bacteria food” material longer (especially on the North-side of the home where it gets less exposure to the UV Rays from the sun) than the paper/asphalt/ceramic shingles of 20+ years ago. Additionally, these particular bacteria enjoy the limestone as a food source.

Once the bacteria have become noticeable, the stains will continue to worsen year to year. There is debate over the actual harmfulness of this particular bacteria to roofs, as there is little supportive scientific research. However, most “experts” within the subject area conclude the bacteria to be harmful, if left untreated, as the growth holds moisture.

Additionally, the continued spread and darkening caused by the bacteria can cause UV attraction that will build higher temperatures in the attic. This will cause your power bills to rise especially in the summer months and can cause the roofing material to “bake” from both sides which will lead to premature failure.
