New Shingle Roof and Plywood Replacement in Bronx NY
RH Renovation NYC completed a comprehensive residential roof overhaul featuring full structural CDX plywood deck replacement, advanced ice dam mitigation, and high-wind architectural shingle installation for a property located in the Bronx, NYC. Densely populated urban residential neighborhoods throughout the Bronx subject steep-slope roofing assemblies to severe environmental demands—including high-velocity wind-shear funneled between closely spaced buildings, driving coastal rain from severe nor’easters, abrasive atmospheric pollution, and aggressive winter freeze-thaw cycles.
Over time, unseen water infiltration through aged shingle layers compromises the underlying timber deck, causing plywood delamination, soft spots, and structural sag. Installing new shingles over a compromised or rotted wood deck guarantees premature fastener pull-out and roof failure. This project was engineered to completely strip away the failing roof structure down to the bare rafters, install brand-new structural CDX plywood sheathing to re-establish frame rigidity, and deploy a synchronized, weather-tight roofing system built for multi-decade durability.
Comprehensive Scope of Work & Installation Methodology
To satisfy strict New York City Department of Buildings (DOB) codes and ensure absolute structural safety and weatherproofing, our licensed and insured Bronx exterior specialists executed a rigorous, multi-phase technical installation protocol:
Complete Tear-Off & Rafter System Audit: All legacy asphalt shingles, degraded underlayment, and waterlogged, rotting plywood panels were completely stripped down to the bare timber roof rafters. Technicians conducted a meticulous structural audit of the exposed framing, replacing damaged rafter sections and leveling the frame to ensure a plumb substrate.
New CDX Structural Plywood Installation: Grade-stamped, exterior-grade CDX plywood sheathing panels were systematically installed and anchored to the rafter network using code-compliant, corrosion-resistant mechanical fasteners. This complete deck replacement eliminated structural sagging, establishing a rigid, high-load-bearing foundation capable of withstanding heavy snowpacks and wind pressures.
Secondary Water Barrier & Ice Dam Defense: High-tensile, tear-resistant synthetic underlayment was installed across the field of the newly laid deck. Heavy-duty, 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 architectural asphalt shingles were meticulously fastened using an enhanced six-nail installation pattern. This specialized fastening schedule provides superior wind-uplift resistance against urban storm gales while delivering a rich, multi-dimensional shadow-line aesthetic.
Perimeter Flashing & Attic Ventilation Refurbishment: Heavy-gauge aluminum drip edges were installed along all perimeter edges to direct 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, and ventilation details complied with strict manufacturer warranty specifications and NYC building codes, followed by a complete magnetic nail sweep and site cleanup.
