Top 4 Reasons to Have Your Roof Cleaned
Chances are you’ve noticed dirty roofs in your area. The dark staining will start appearing 3-5 years after the new asphalt shingle roof is installed. The staining is caused by a bacteria called Gloeocapsa Magma, often referred to as “roof algae”. The roof stains will be minimal at first, but then over the next couple years the staining will grow quickly. The roof algae will multiply, often times the worst areas will be the North side of the roof where the shingles get the least amount of sunlight. These dark, damp conditions will help the algae thrive. The algae will feed off of the limestone granules that are added to asphalt shingles as a filler to weigh them down and help protect your roof.
These stains can be safely removed from your asphalt shingle roof by using a no pressure roof cleaning method. This method is recommended by the Asphalt Roofing Manufacturers Association.
There are 4 main reason you should have your roof cleaned.
1. The buildup of roof algae will cause premature roof replacement. A very costly repair!
2. Roofs with black stains from roof algae will drastically lower the property resale value.
3. Insurance companies have been known to cancel policies on your roof if they determine the amount of buildup is deemed negligent.
4. A black stained roof will draw in more heat and therefore will raise your utility bill!
