People are often surprised to learn that the black staining on their roof is almost always algae and mold. More often than not, it appears on the North side of the roof where there is less exposure to the sun and moisture hangs around longer.

It survives by feeding off the limestone fillers in the shingles. As it feeds, it grows and spreads across the roof. Over a period of years, the algae will eat enough of the shingles to begin to loosen up the protective surface granules. As the shingles lose these protective granules, their protective qualities degrade. These granules help protect the shingles and reflect the sun’s rays to keep your home cooler.

Your Stained Roof Can Look New Again, Last Longer, And Save You Energy Cost
There are three major problems associated with biological attack on asphalt roofs-appearance, shortened roof life, and increased energy cost. Algae and fungi growth on roofs may also contribute to allergies.

Is Your Roof An Eyesore?
Roof stains caused by algae attack start out as areas of light discoloration then turn to unsightly black or dark brown streaks. If not stopped, the entire roof will become an even worse eyesore as the algae continues to grow and deteriorate. These ugly roof stains detract from your home's curb appeal, pride of ownership, and may affect its resale value. Realtors almost always recommend removing these unsightly stains from your roof before listing your home for sale.

A Clean Roof Will Last Longer
Biological attack from algae can cause damage to your shingles and shorten the life of your asphalt roof. The algae take root on the surface of your shingles helping to dislodge the protective granules. Surface temperatures are also increased because of the dark stains. Its growth holds water on the roof's surface which also intensifies the sun's ultra violet rays like a magnifying glass. The increased moisture and UV rays work to further dislodge the protective granules and attack the shingle's protective asphalt coating. Moisture, UV rays, and thermal movement from temperature extremes are your roof's greatest enemies. All three are intensified by algae growth. It can suck the life from your asphalt roof leading to earlier than necessary roof replacement.
