Do you have black streaks appearing on your roof? Can you see green moss and algae growing there also? If so, your roof is under attack and you must take action!
Many homeowners aren’t aware of the exclusions found in their roof warranty. A typical roof shingle limited warranty doesn’t provide protection against failure, defect or damage caused by situations or events beyond normal exposure conditions, including shading, stains or discoloration arising from outside sources such as mold, mildew, algae, fungus, moss, lichens or other vegetation.
Moss, lichen and algae have firmly-planted root systems that drain vital nutrients from your asphalt shingles. Their roots pull at the shingles, causing them to cup; this cupping causes shingle granules to detach and fall off. Without the protective granules in place, your shingle’s surface is exposed to the merciless sun’s damaging rays; it is at this stage that roof leaks are likely to occur, making an early roof replacement necessary.
Just as a solid foundation supports your house, your roof protects everything and everybody in your home. If your roof is not maintained and properly cleaned, rapid algae growth can cover the entire surface, quickly destroying its structural integrity.
A deteriorating roof also detracts from curb appeal and can dissuade a prospective home-buyer; the cost of replacing a roof can deter the most motivated buyer. In this “buyer’s market,” sellers need to stand out in the crowd, by providing prospective buyers with records showing a well-maintained roof, for example.
Many factors can compromise the integrity of your roof; deteriorating shingles that trap moisture is one of them. Now that winter, and the weight of snow on your roof, is gone, it’s time to perform maintenance before our next harsh winter.
Maximize your roof’s life expectancy and save thousands of dollars by avoiding a premature and costly roof replacement. Have your roof inspected annually and clean it of unwelcome algae, lichen, moss, fungus, dirt and grime. Unsightly black streaks that stain your roof can be safely and effectively removed with a cleaning application, followed by a low-pressure rinse. A preservative is strongly suggested and will slow down the re-birth of rooftop algae and other unwanted growth, doubling the time between cleanings.
