Roof algae, commonly known as Gloeocapsa Magma, is a type of algae that thrives in humid and warm climates and usually appears first on the North slope of the roof where shade is prevalent and moisture tends to accumulate. The result is usually a black streaked roof.
Roof algae, once attached to a shingled roof, feeds on the dead organic matter used in the manufacturing process of the shingle. As the fungus breaks down the asphalt shingle, the ceramic granules protecting the surface of the shingle are loosened and begin to fall off. This causes the roof to deteriorate prematurely and diminishes the roof's abilities to reflect heat rays. If not treated, the roof algae will reduce the life of your roof, diminish your home’s curb appeal and increase your home cooling expenses.
Unfortunately, traditional roof cleaning methods have used high pressure washing and/or hazardous chemical ingredients such as bleach, sodium hydroxide (Lye), copper, zinc, or acid. These techniques can damage the integrity of the roof, your landscaping and even cause harm to siding, brick, windows, gutters or even pets. Our products are biodegradable, non-corrosive and in most cases, do not require any rinsing, thus virtually eliminating the need for damaging pressure washing.
The initial removal of roof algae and moss is always more difficult then the prevention of roof algae or moss once the roof is cleaned. A standard practice should be to clean your roof and then apply a preventative treatment every 12-24 months to keep the stains from returning. Roof cleaning and prevention has never been easier.
