What Are Roof Stains?

Roof stains…not only are they ugly and impact your property’s curb appeal, but they also can cause severe damage to your shingles! If you’ve ever wondered where the stains come from, the simple answer is from a living “plant” called Gloeocapsa magma. This algae is feeding on the limestone filler used to add weight to asphalt shingles. The reason it is more prominent on the north side and shaded areas of your roof is that these areas get the least amount of sunlight which causes that area of the roof to stay wetter longer. Lack of sunlight means moisture from morning dew, and rain remains in these areas longer, creating the perfect environment for maximum growth.

As previously mentioned, the “simple” answer is a living plant causes discoloration. To get a bit more technical, that “plant” is a Cyanobacteria. Once the colony gets established, it creates a petri-dish effect on your roof, allowing dozens of different hazards to thrive, such as lichen, mold, mildew, moss, and even ferns! Over time this can cause damage to your roof and shorten its lifespan.
