Microbes could be bugging your roof

Envirowash Hawaii recommends you take a look at your roof. Living in Hawaii — with our humid environment — chances are your roof has black streaks, patches or has completely been darkened. This is not the normal process for roof aging. Your roof is actually being infested by an aggressive form of bacteria called Gloeocapsa magma. This bacteria is colonizing on your roof and feasting on the limestone that roofing manufacturers now use as a filler to replace the asbestos that was used in shingles prior to the late 1970s.

These bacteria escalate the deterioration of you roof by laying extensive filament root systems that burrow down into the roofing materials and eat the limestone, creating fissures and cracking. The waste they excrete after feasting on your roof is acidic and furthers the destruction of your roof system. This process also creates a warm and inviting environment for other aggressive forms of mold, algae, lichens and bacteria to flourish. Not only does this affect the roof, but it also can lead to allergies in people. A problem that effects both the roof and the homeowners is the heat produced by the darkening of the roof. The excess heat dries the roofing materials out and causes premature aging. The homeowner is directly affected by how much extra energy is required to cool off the house, which leads to extra money out of their pockets.

Fortunately there is a cost-effective, environmentally safe treatment that will not damage your roof.

“Because we know these bacteria are a living organism, we know it is not a cleaning issue but a treatment issue,” said Mike Wedge of Envirowash Hawaii. “You cannot simply blast it away with a pressure washer. You will only break the stems at the surface leaving the root system to grow back thicker and fuller than before. You must achieve a 100 percent kill ratio to eradicate the problem.” Envirowash Hawaii is Hawaii’s only certified soft wash cleaner and recommends a roof cleaning every five to seven years to help reach the full duty cycle of your roofing system.
