Project: New Roof Installation Service

RH Renovation NYC completed a total steep-slope roof replacement and structural envelope upgrade featuring complete legacy roof tear-off, timber subdeck sheathing remediation, rubberized self-adhering ice-and-water shield laydown, high-tensile synthetic underlayment application, and high-wind architectural shingle weaving for a residential property in the Greater New York City area. Steep-slope residential roof assemblies throughout the Northeastern urban corridor are continuously subjected to severe environmental pressures—including wind-driven rain from seasonal nor’easters, extreme summer UV degradation, high wind-shear gusts, and severe winter freeze-thaw cycles that induce destructive ice damming.

When an aging roof assembly suffers from granule depletion, tab seal failure, or underlying deck moisture saturation, water bypasses the outer primary barrier. Trapped moisture rapidly degrades structural roof sheathing, causes rafter decay, ruins attic insulation efficiency, and risks interior ceiling and drywall damage. Executed with a focus on optimizing both technical durability and overall cost-efficiency, this project delivered a complete top-to-bottom roof renewal: stripping away compromised legacy layers, reinforcing the structural substrate, establishing dual-tier leak defense, and precision-installing heavy-gauge architectural shingles engineered for long-term weatherproofing.

Comprehensive Scope of Work & Installation Methodology

To satisfy strict regional building safety codes and national roofing industry standards, our licensed and insured exterior specialists executed a systematic, multi-phase technical installation protocol:

• Complete System Tear-Off & Substrate Audit: Technicians systematically stripped away all layers of deteriorated legacy shingles, failed felt paper underlayments, and corroded flashing components down to the raw timber decking. Exposed plywood panels and rafter tails were thoroughly audited to identify hidden moisture rot or structural deflection.

• Subdeck Remediation & Structural CDX Plywood Replacement: Water-damaged, delaminated, or soft wood decking sections were excised and replaced with structural CDX exterior-grade plywood sheathing. Replacement panels were double-fastened directly to rafter joists to re-establish a rigid, flat, and nail-tight fastening base across the entire roof surface.

• Dual-Tier Waterproofing & Ice-Dam Barrier Application: Heavy-duty rubberized self-adhering ice-and-water shield membranes were installed continuously along high-stress eave margins, rake edges, valley lines, and wall transitions to prevent water intrusion caused by winter ice dams. High-tensile synthetic underlayment was laid across the remaining roof field, providing superior UV resistance and secondary moisture defense compared to traditional felt paper.

• Architectural Shingle Weaving & High-Wind Fastening Schedule: Premium dimensional architectural asphalt shingles were installed across the prepared roof deck using an engineered six-nail fastening schedule per course. Starter strip shingles were locked securely along perimeter eave and rake edges to guarantee maximum resistance against high urban wind-shear uplift.

• Perimeter Flashing Refurbishment & Polyurethane Sealing: Heavy-gauge aluminum drip edge flashings, step flashings at wall intersections, and plumbing vent pipe boots were integrated and sealed using industrial non-sag, UV-resistant exterior polyurethane lap sealants.

• Quality Tightness Audit & Magnetic Clean Sweep: A thorough multi-point inspection was conducted across all hip, ridge, valley, and penetration courses to confirm complete seal integrity, followed by a meticulous magnetic ground sweep to clear all metal fasteners and job site debris.
