Roof Cleaning
Many folks move to the southeast from other parts of the country, and soon find themselves greatly enjoying our mild winters, easy-going lifestyle and, of course, southern charm. Inevitably, however, the day comes when the unsuspecting homeowner walks outside, looks up, and shouts to anyone within earshot:
“Hey!! What is that black stuff on my roof?”
The black streaking typically found on homes in our area where humidity-driven moisture settles on shingles is not caused by mildew or fungus; it’s roof algae. 3M scientists have identified the most common form as Gloeocapsa Magma. Algae spores are carried by the wind, which is why so many houses in the same neighborhood can end up with this problem. Over the past 20 years or so, this particular algae strain has become hardier, the staining is showing up earlier, is more severe and settles on a greater number of roofs.
