In our local climate, the best prevention is a combination of proper installation and regular maintenance. We ensure your gutters are correctly sized and pitched for your specific roof, and we strongly recommend installing quality gutter guards to minimize clogs from leaves and debris common in the area. An annual inspection and cleaning, especially in late fall, is key to preventing overflow and protecting your home's foundation.

Those dark streaks are likely Gloeocapsa magma, a type of algae that thrives in the humid, shaded conditions common in Maryland. While not immediately damaging to the shingles, it can shorten their lifespan and affect curb appeal. We use professional, low-pressure cleaning techniques with EPA-approved solutions to safely kill the algae and rinse it away without damaging your shingles. We can also apply a zinc or copper strip treatment at the roof's peak to help prevent regrowth.

We recommend a professional inspection at least once every two years, and always after a major storm with high winds or hail. Regular inspections allow us to spot minor issues—like a few lifted shingles or a small gutter leak—before they lead to major water damage or more costly repairs inside your home. Catching problems early is the most effective way to extend your roof's life and maintain your home's value.
