Bay Area Roof Cleaning Contractor
A general misconception among the public is the fact that discolored roofs are the result of age and deterioration that soon will require replacement. To the contrary, discoloration is the result of an air-borne fungus known as Gloeocapsa Magma. It can be identified as dark or black staining or streaks and is most noticeable on lighter colored roofs, but can be found on most any roof. Gloeocapsa Magma feeds on humidity, heat and some form of nutrient. The nutrient can come from pollutants, fallen leaves and limestone found in the shingle itself.
WHY IS ROOF FUNGUS A PROBLEM?
According to the Asphalt Roofing Manufactures Association ( ARMA ), roofs that have a substantial amount of this algae can absorb as much as 30% more heat due to the black pigmentation. This heat absorption leads to shingle deterioration and higher electric bills. Moreover, not only are these roofs unsightly, the presence of this fungus in such close proximity to a living environment can pose health concerns for those with allergy problems.
WHAT CAN BE DONE?
Fortunately, this problem can be eliminated. Using low pressure and environmentally safe Bay Area roof cleaning compounds, the fungus along with mildew and lichens can be dislodged and easily rinsed from the roof without damaging the integrity of the shingle. This is a relatively inexpensive procedure that can add years to your Bay Area roof. Once initially cleaned, an annual maintenance coating is recommended to prevent recurring growth.
