The bacteria growth on your roof can really shorten its life.
Most homeowners think that the ugly black streaks on their roofs are normal shingle wear and tear and many replace their roofs prematurely. That ugly black streaks are caused by the bacteria called Gloeocapsa Magma (GM), often known as "algae growth on the roof". The GM feeds off of both asphalt and limestone roofing causing early deterioration of the roof.
Other natural elements found on the roofs are mold, moss, and lichen which also cause early deterioration of the roof and wood rot.
Roofs covered with algae, mold, moss, or lichen do not efficiently reflect sunlight which causes shingles to absorb heat. This may increase the heat in your attic, raising cooling costs.
The frequency to have a roof cleaned really depends on the conditions, however a good and safe practice is to have your roof cleaned every 4 or 5 years to add years to its life, to keep it looking new and also to increase the curb appeal of your house.
It is strongly recommended to hire a professional company to clean your roof to avoid any accidents and damages to your roof & vegetation.
