SOFT WASH ROOF CLEANING

What Are The Black Streaks On My Roof?

Unsightly black stains or streaks on asphalt shingles are caused by a hardy type of algae called Gloeocapsa Magma. The algae feeds on the crushed limestone that is used in asphalt shingles. Rain spreads the algae down the roof causing the black streaks. You will probally notice that these stains are mainly on your north and east facing roof lines. Algae is a living and growing organism that feeds off moisture. These streaks are not only unsightly but cause the shingles to fail prematurely by not allowing the shingles to reflect heat properly. This type of algae can also be spread from roof to roof by mother nature.

45% Of Roofs Are Replaced Due To The Way They Look...

Not because of their functionality. Many of the roofs that are replaced only needed cleaned. Just as mold and mildew can grow on your vinyl siding, windblown algae can land and grow on your roof. Replacing your roof because of this algae is like replacing something that is not broke; it just doesn't make sense.
Some roofing contractors don't know what these black streaks are, saying it's the asphalt showing through the shingles or that it's water stains. Some contractors may know it's algae but tell you it can't be cleaned without damaging the shingles. In either case, they may tell you that the roof needs replaced. This is not true if your shingles are still in good shape. The algae can be killed and removed properly without damaging the shingles using a low pressure chemical application (recommended by shingle manufactures).
Squeegee Klean uses a low pressure cleaning procedure for roofs that will not damage the shingles and will remove those unsightly black streaks, algae, mold, dirt etc.
