Roof Magic Roof Cleaning Service.If the roof on your house is becoming covered with black streaks, particularly on the North side, you are not alone. Nearly every roof more than six years old will develop streaking due to moss, mildew, lichens, and Gloeocapsa Magma blue-green algae. Not only does this detract and devalue the look of your home, but all can actually feed on the shingles themselves. Roots will penetrate the shingles and loosen the protective granules, accelerating wear by exposing the asphalt to the suns rays. Treating early is the key to your roofs longevity.We bring to your home a carefully engineered roof cleaning system that will remove damaging moss, mildew, and fungus with a minimal chance of damage. Roofing manufacturers recommend against power washing their shingles, and against using bleach, both of which can harm and shorten the protective life of your shingles. We've evolved a system that employs neither. Additionally, we back up our work with a two-year guarantee against re-growth, or we will return and re-clean the roof at absolutely no cost to you.
