Sunny View Roofing | Roofing Services in Lewistown, PA 17044

In Lewistown, nail pops are often caused by the expansion and contraction of roof decking due to our seasonal temperature swings. When a nail works loose, it can compromise your roof's seal. We fix this by carefully removing the popped nail, securing the shingle with a new, corrosion-resistant nail, and sealing it with a matching, high-grade roofing cement to prevent future leaks and ensure a watertight repair.

Yes, those black streaks are likely Gloeocapsa magma algae, which is common in our humid Pennsylvania climate. While it starts as a cosmetic issue, the algae colony can retain moisture and slowly degrade the protective granules on your asphalt shingles, shortening their lifespan. Our professional, low-pressure cleaning safely removes the algae and applies a treatment to inhibit its return, protecting your investment.

Regular maintenance is key. We recommend a professional roof inspection at least every two years, especially after severe weather. For prevention, ensure your attic has proper ventilation to reduce thermal stress that causes nail pops. For algae, consider installing zinc or copper strips near the roof peak during your next replacement; these metals release ions that wash over the shingles and naturally inhibit algae growth.
