New Roof Shingles Installation Project
RH Renovation NYC completed a precision residential steep-slope roof replacement featuring complete tear-off down to the raw timber deck, structural sheathing remediation, synthetic waterproofing underlayment laydown, and high-wind architectural shingle application. Densely populated urban and suburban neighborhoods across the Greater New York City area subject residential roofing systems to severe year-round weather dynamics—including heavy driving rain from seasonal nor’easters, coastal wind-shear, intense summer heat cycles, and severe winter freeze-thaw fluctuations.
Over time, these severe environmental factors erode asphalt shingle protective granules, weaken nail-holding capacity, and degrade legacy felt underlayments. When moisture penetrates the outer shingle layer, it causes structural plywood sheathing to rot, increases attic humidity, and threatens interior ceiling structures. This project was engineered to strip away the failing roof assembly down to the underlying framing, reinforce subdeck structural integrity, and deploy an engineered, weather-resistive architectural shingle system built for multi-decade durability, weather tightness, and high thermal efficiency.
Comprehensive Scope of Work & Installation Methodology
To satisfy strict regional building code standards and national roofing industry guidelines, our licensed and insured roofing specialists executed a systematic, multi-phase technical protocol:
Complete Tear-Off & Subdeck Remediation: All existing layers of aged asphalt shingles, degraded underlayment, and rusted flashings were stripped down to the bare timber roof decking. Technicians performed a comprehensive structural audit, removing warped or water-stained plywood panels and installing thick, grade-stamped CDX structural sheathing to establish a rigid, level base.
Secondary Moisture Barrier & Ice Dam Defense: High-tensile synthetic underlayment was installed across the entire roof deck field. Self-adhering ice-and-water shield membranes were extended along all eaves, rakes, valleys, chimneys, and plumbing penetrations to block wind-driven rain and prevent ice dam backups during freezing winter months.
High-Wind Architectural Shingle Application: Premium dimensional architectural asphalt shingles were meticulously applied using an engineered six-nail fastening schedule. This specialized technique significantly boosts wind-uplift resistance against heavy storm gales while delivering a rich, multi-dimensional shadow line that enhances home curb appeal.
Perimeter Flashing & Drip Edge Refurbishment: Heavy-gauge aluminum drip edges were installed along perimeter margins to direct rainwater directly into gutter channels without wicking back onto fascia boards. All high-risk transition zones—including chimney step flashings, wall aprons, plumbing boots, and continuous ridge vents—were replaced with corrosion-resistant components to ensure balanced attic ventilation.
Final Quality Control & Site Cleanup: A multi-point quality inspection verified complete shingle alignment, proper fastener placement, and flashing tightness, followed by a thorough magnetic nail sweep across the property grounds.
