Project: New Roof Installation in the Bronx

RH Renovation NYC completed a comprehensive residential roof replacement featuring complete tear-off of deteriorated legacy roofing, structural subdeck sheathing remediation, self-adhering waterproofing membrane installation, and high-wind architectural shingle application for a property located in The Bronx, NYC. Multi-family and single-family residences throughout The Bronx face rigorous urban microclimate exposure—including high-velocity wind-shear funneled through dense building corridors, torrential driving rains from seasonal nor’easters, intense thermal expansion cycles, and severe winter freeze-thaw shifts.

When an aging roof assembly suffers widespread granule loss, cracked shingle fields, or compromised underlayment, water breaches the secondary defense layer. Continuous moisture intrusion rots structural roof deck sheathing, degrades attic thermal insulation, and leads to costly interior ceiling damage. This project was engineered to systematically strip away the exhausted roofing structure down to the raw framing, restore the underlying structural subdeck, and install an engineered, weather-resistive architectural shingle roof system designed for multi-decade durability, weather resistance, and thermal efficiency.

Comprehensive Scope of Work & Installation Methodology

To satisfy strict New York City Department of Buildings (DOB) code standards and national roofing guidelines, our licensed and insured Bronx roofing crew executed a rigorous, multi-phase technical installation protocol:

• Complete Tear-Off & Structural Framing Audit: Technicians systematically removed all existing layers of damaged asphalt shingles, waterlogged underlayment, and corroded flashings down to the bare timber roof decking. A structural audit was conducted across the exposed framing to identify and replace water-stained, delaminated, or soft plywood panels with thick, grade-stamped CDX structural sheathing to establish a level, rigid substrate.

• Secondary Waterproofing & Ice Dam Barrier Laydown: Heavy-duty, high-tensile synthetic underlayment was installed across the entire roof deck field. Self-adhering ice-and-water shield membranes were applied along all critical perimeter areas—including eaves, rakes, valleys, sidewalls, and plumbing vent penetrations—to prevent wind-driven rain infiltration and winter ice dam backups.

• High-Wind Architectural Shingle Application: Premium dimensional architectural asphalt shingles were meticulously laid and secured using an engineered six-nail fastening schedule. This specialized installation technique significantly enhances wind-uplift resistance against severe urban storm gales while providing a multi-dimensional shadow line that elevates home curb appeal.

• Perimeter Flashing & Attic Ventilation Optimization: Heavy-gauge corrosion-resistant aluminum drip edges were installed along all perimeter margins to direct water runoff cleanly into gutter systems without saturating fascia boards. All critical transition flashings were replaced, and a continuous ridge ventilation system was integrated along the peak to optimize attic airflow and release trapped thermal moisture.

• Final Quality Control & Site Cleanup: A thorough multi-point quality assurance inspection verified shingle course alignment, fastener depth, and flashing tightness, followed by a full magnetic nail sweep across the property grounds.

Results & Homeowner Value

By removing the compromised old roof structure and installing an advanced architectural shingle system backed by reinforced subdeck waterproofing, RH Renovation NYC permanently eliminated the home’s water intrusion vulnerabilities. The Bronx homeowners now benefit from complete defense against severe seasonal New York weather, improved thermal envelope efficiency, and a beautifully restored exterior that enhances long-term property equity.
