Unity Masonry and Roofing | Roofing Services in Yonkers, NY 10704

Overflowing gutters are a common issue in our area, often caused by clogs, improper pitch, or undersized systems. We start with a thorough inspection to diagnose the root cause. For many homes, a professional gutter cleaning resolves the immediate problem. If the system is damaged or incorrectly sized, we recommend repair or a complete replacement with larger, seamless gutters designed for Yonkers' rainfall levels. Proper installation is key to directing water away from your roof and foundation, preventing the water damage and algae-friendly moisture that overflow creates.

Those black streaks are typically Gloeocapsa magma algae, which thrives in our humid climate and feeds on limestone in asphalt shingles. While not immediately damaging, it traps moisture and can shorten roof life. Our solution begins with a safe, professional roof cleaning to remove the existing growth. To prevent quick regrowth, we then apply a specialized sealant or recommend zinc/copper strip installations at the roof ridge. During our inspection, we'll also check for related issues like compromised shingles or poor ventilation that algae can exploit.

A holistic approach is best. It starts at the top: ensuring your roof and gutter system are functioning perfectly to channel water away. From there, we look at the entire envelope. This includes sealing exterior masonry walls, installing proper drainage like French drains or sump pumps in basements, and constructing retaining walls to manage soil erosion and groundwater. Waterproofing isn't just one service; it's a system. We connect your roofing health to your masonry and ground-level defenses, offering integrated solutions like driveway sealing and patio waterproofing to create a complete moisture barrier for your property.
