Those black streaks are actually a type of algae, often called Gloeocapsa magma, which thrives in our region's humid climate. It feeds on the limestone filler in asphalt shingles. While it doesn't always cause immediate damage, it can retain moisture and shorten your roof's lifespan. At A Shultz Roofing & Siding, we perform a professional cleaning with specialized, eco-safe solutions to remove the algae without harming your shingles. For a permanent solution, we can also install algae-resistant shingles on your next roof replacement to prevent future growth.

Yes, chimney flashing—the metal seal where the chimney meets the roof—is the most common source of leaks in that area. Over time, weather, expansion, and contraction can cause the flashing to crack, rust, or pull away. Our team at A Shultz Roofing & Siding conducts a thorough inspection to diagnose the exact issue. We then repair or completely replace the flashing using high-quality, durable metals and precise installation techniques, ensuring a watertight seal that protects the vulnerable intersection of your chimney and roof for the long term.

Proactive maintenance is key. We recommend scheduling a professional roof inspection with us at least once every two years, especially after severe weather. For algae, ensuring your gutters are clean and trimming back overhanging tree branches to increase sunlight and airflow can help slow growth. For flashing, regular visual checks from the ground for signs of rust, gaps, or damage are wise. The best prevention is partnering with a local expert. At A Shultz Roofing & Siding, our maintenance checks are designed to catch small issues like worn flashing or early algae spread before they turn into costly leaks or major repairs.
