Many homeowners in Indiana are all too familiar with black roof streaks. These unsightly black streaks diminish the asphalt shingles, raise your home heating and cooling costs, and can lower the value of your home. These black roof stains are caused by an airborne algae. These algae land on the shingles and begin to feed on them. They normally first start appearing on the north facing slopes of the roof where shade and moisture are most common. With nutrients and moisture the algae are able to survive. Each time it rains the algae is pulled down the roof creating unsightly black streaks. If not taken care of the black algae streaks will eventually turn the entire roof black and will lessen the longevity of the shingles costing the homeowner money. Half of the roof’s replaced in Indiana are replaced due to the roof’s appearance not because of it’s functionality. This means homeowners are not aware what these black streaks are and that there is a solution. Unfortunately, most roofing contractors are also not aware of roof algae therefore insisting that roofs need to be replaced. Don’t be fooled into replacing a roof that can be cleaned for a tenth of the cost. There is no reason a thirty or forty year shingle should be replaced any sooner. Call a roof cleaning company and get a free evaluation before you decide to have the roof replaced.
