Have you noticed black streaks and stains on your roof and wondered what is causing it or if it is already time to replace your roof?These streaks and stains are caused by mold, mildew, and Gloeocpsa Magma which is Roof Algae. Roof Algae is carried by wind, birds, squirrles, etc. It thrives in warm, humid climates. As the Algae grows on your roof, they eat away the base of the shingle and expand andcontract with the outside temperature. This growth and movement loosens the granules, creating premature granule loss. The granule loss dramatically shortens the life of your roof, makes your roof absorb more heat, raises your energy bill, and decreases the value of your home. Having your roof cleaned will extend the life of your roof, increase your homes energy efficiency,and increase the value of your home.
