How to Prevent Roof Stains Caused By Moss and Algae

Your roofing system not only protects your home from weather damage–it also contributes greatly to its curb appeal. For this reason, you’ll want to take proactive measures that can keep your roof lovely and pristine all year round. This means preventing unsightly moss and algae stains from developing on its surface. Sterling Exteriors, the trusted roofing and siding company in the area, shares some handy tips.

  • Trim back encroaching tree branches. Do this regularly for the simple reason that they’ll shed leaves and other loose debris (which then pile up on top of the system) if you leave them unattended. Roof debris retains excess moisture, and this encourages biological growth such as mold and algae. This can leave your roof stained, while fast-tracking its deterioration.
  • Have your roof cleaned regularly. Aside from cutting back the tree branches hanging over your roof, you should also schedule a comprehensive roof cleanup at least once a year. This, too, will prevent debris from building up on your roof. Sterling
  • Invest in a quality roofing system that has algae resistance. Choosing a system that is impervious to algae and moss in the first place is probably the easiest way to prevent stains on your roof. Sterling Exteriors, premier roof repair and replacement expert, offers high-quality asphalt shingle roofing systems from GAF®, North America’s largest roof manufacturer. Our options come with StainGuard® Plus™ Time Release Technology, which discourages pronounced discoloration from blue-green algae. 

StainGuard® Plus™ Time Release Technology makes this possible by using specially engineered capsules infused throughout with copper microsites. The copper remains on hand, ready to be activated to help prevent algae and moss in your roof. This is a definite upgrade to the obsolete method that involves concentrating the copper in a layer. What’s more, GAF shingles with StainGuard Plus Time Release Technology come with a 25-year warranty covering against blue-green algae discoloration.
