Greco Construction | Roofing Services in Holbrook, NY 11741

We see these issues frequently in our area due to weather exposure. Our approach is thorough: we start with a detailed inspection to assess the full extent of the damage, not just the surface problem. For roof deck rot, we carefully remove the affected sheathing and replace it with new, code-compliant materials. For underlayment damage, we ensure the entire roof deck is properly prepared and sealed before installing a new, high-quality underlayment as a critical moisture barrier. Our goal is to fix the root cause to protect your home's structure for the long term.

Our process is collaborative and detail-oriented. We begin by understanding your vision, budget, and timeline. With over 27 years of experience, we then manage all phases—from initial design and permitting to demolition, construction, and final finishes. We specialize in these complex projects and pay close attention to the functional layout, plumbing, electrical, and cabinetry work. Our crew works closely together to ensure minimal disruption and clear communication, keeping the project on track toward a result you'll love for years to come.

Absolutely. Our scope ranges from specific repairs like roof leaks or skylight installation to complete projects like building additions, ADUs, or new single-family homes. As licensed general contractors, we have the expertise and crew to scale our services to your needs. Whether it's a gutter replacement or constructing a modular home, we apply the same standard of quality, attention to detail, and commitment to clear communication that has defined our family business since 1989.
