Topside Roofing | Roofing Services in Yorktown Heights, NY 10598

This is a very common issue here due to ice dams. Snow on your roof melts from heat escaping your attic, then refreezes at the colder eaves, creating a dam. As more snow melts, water backs up under the shingles, leading to leaks. We perform thorough inspections to identify damage from ice dams and repair compromised areas, often recommending improved attic ventilation to prevent future problems.

Those dark streaks are typically Gloeocapsa magma, a type of algae that thrives in our humid climate. It feeds on the limestone in asphalt shingles. Yes, we can safely remove them! We use professional, low-pressure soft washing techniques with eco-friendly solutions that kill the algae without damaging your shingles, restoring your roof's appearance and preventing the organic growth from shortening its lifespan.

First, contain any active drip with a bucket and try to locate the general area in your attic. Then, call a professional roofer like Topside for an inspection. It's crucial to address the leak's source promptly to prevent mold and structural damage. We'll assess the damage from the ice dam or other issues, provide a temporary mitigation plan if needed, and schedule a permanent repair to ensure your Yorktown Heights home stays dry.
