We just love the results of this roof cleaning in Jackson NJ 08527 . These roof stains are typical of an asphault shingle roof. Most people in this area think because they are near the Air Force base that jet fuel/exhaust has something to do with causing the roof stains. These stains are cause by a hardy breed of mold that feeds on the crushed limestone used to make the shingle. not only do the stains look bad, they actually absorb heat and create higher cooling costs in the Summer. They also weaken the granules of the shingle causing premature failure. We perform many roof cleanings in Monmouth County NJ. This type of staining is contagious and can jump from house to house through wind, birds, and squirrels. When it rains the water pulls the bacteria down to create the streaking pattern. These stains can be treated without the use of a power washer or any other damaging type of high pressure machine.
