Oyster Bay Roofing & Sheet Metal Inc. | Roofing Services in Oyster Bay, NY 11771

Our coastal climate subjects roofs to constant wind, salt air, and temperature fluctuations, which can loosen and deteriorate flashing seals over time. Our specialty is in sheet metal fabrication and installation. We don't just patch it; we assess the entire system, remove compromised sections, and custom-fit new, high-quality flashing. We then seal it with durable, weather-resistant materials designed for Long Island conditions to create a long-lasting barrier against water intrusion.

Those dark streaks are typically Gloeocapsa magma algae, which thrives in our humid environment. It's more than just a cosmetic issue. The algae can retain moisture against shingles, accelerating granule loss and shortening your roof's lifespan. We offer professional roof cleaning services that safely and effectively remove the algae without damaging your shingles. We can also apply preventative zinc or copper strip treatments at the ridge to inhibit future growth.

Our local inspection is thorough and focused on our common issues. We start with a visual assessment of the roof plane and valleys, then carefully examine all flashing points—around chimneys, vents, and skylights—for any separation or corrosion. We check for algae growth and assess shingle condition for moisture damage. Finally, we inspect the attic for signs of leaks or inadequate ventilation. You'll receive a clear, detailed report with prioritized recommendations and transparent pricing for any necessary repairs or maintenance.
