Shingle Roof Replacement and New Plywood Installation
RH Renovation NYC completed a comprehensive multi-phase roofing overhaul featuring full structural CDX plywood subdeck replacement, synthetic weatherproofing integration, and high-wind architectural shingle installation for a residential property in New York City. Densely built residential structures across the metropolitan area are exposed to intense environmental dynamics—including accelerated wind-shear funneled between closely set multi-story buildings, driving coastal nor’easters, heavy atmospheric pollution, and severe freeze-thaw cycles.
When aging shingles lose their protective granule coating alongside rotting or delaminating subdeck sheathing, water infiltration quickly compromises multiple building envelope barriers. Installing new shingles over soft or compromised wood sheathing guarantees premature fastener failure, sagging rooflines, and active interior water damage. This project was engineered to strip away the failing roof system down to the bare timber rafters, rebuild the structural wood deck with code-compliant plywood, and deploy a synchronized, weather-tight roofing system built for multi-decade durability and energy efficiency.
Comprehensive Scope of Work & Installation Methodology
To satisfy strict local building codes and deliver absolute weather-tight security, our licensed and insured exterior specialists executed a rigorous, multi-phase technical installation protocol:
Complete Tear-Off & Structural Framing Audit: All legacy asphalt shingles, degraded underlayment felt, and waterlogged, rotting plywood sheathing were completely stripped down to the bare structural roof rafters. Technicians conducted a detailed structural audit of the exposed framing, replacing damaged rafter timber and leveling framing connections to establish a plumb substrate.
New Structural CDX Plywood Installation: Grade-stamped, exterior-grade CDX plywood sheathing panels were systematically installed and anchored across the rafter network using code-compliant, corrosion-resistant framing fasteners. This complete deck replacement eliminated structural sagging, re-establishing a rigid, high-load-bearing foundation capable of withstanding heavy snowpacks and high wind uplift forces.
Secondary Waterproofing & Ice Dam Defense: High-tensile, tear-resistant synthetic underlayment was installed across the newly laid plywood deck to serve as a high-durability secondary moisture barrier. Self-adhering ice-and-water shield membranes were applied along all eaves, rakes, valleys, chimneys, and roof penetrations, extending well beyond interior wall lines to permanently neutralize winter ice dam backups and wind-driven water intrusion.
High-Wind Architectural Shingle Application: Premium dimensional asphalt shingles were meticulously fastened using an enhanced six-nail installation pattern. This specialized fastening schedule delivers exceptional wind-uplift resistance against severe coastal storm gales while providing a rich, multi-dimensional shadow-line finish.
Perimeter Flashing & Attic Ventilation Refurbishment: Heavy-gauge aluminum drip edges were installed along all eaves and rakes to protect the roof deck edge and direct water runoff cleanly away from the fascia. All critical transition zones—including chimney step flashings, wall aprons, plumbing pipe boots, and continuous ridge vents—were replaced with corrosion-resistant metals to optimize attic airflow and prevent thermal moisture buildup.
Final Quality Assurance & Compliance Audit: A thorough multi-point inspection verified that all structural fastening, membrane laps, flashing integrations, and ventilation details met strict manufacturer warranty specifications and municipal building codes, followed by a complete magnetic nail sweep and site cleanup.
