Project: Skylight, Roofing and Chimney Repair Service

RH Renovation NYC completed an integrated multi-point roof envelope repair and masonry restoration project featuring skylight perimeter flashing overhaul, architectural asphalt shingle matrix repair, and chimney brickwork repointing with custom step/counter-flashing encapsulation for a residential property in the Greater New York City area. Rooftop penetrations and masonry projections—specifically skylights and chimneys—represent the most complex and water-vulnerable intersections on a steep-slope roof assembly. In Northeastern coastal and urban environments, these transition points face continuous microclimatic stress, including severe freeze-thaw expansion, wind-driven rain from seasonal nor’easters, thermal shock, and high wind-shear.

When a skylight’s perimeter seal or step flashing degrades, water bypasses the roof deck and causes severe interior ceiling drywall damage, framing decay, and attic insulation saturation. Concurrently, aging chimney masonry joints absorb standing moisture that freezes and fractures brickwork, while failing chimney flashings allow rainwater to run directly down structural rafters. Executing a simultaneous restoration across the skylight, surrounding shingle matrix, and chimney stack eliminates interconnected leak pathways and re-establishes a seamless, watertight building envelope.

Comprehensive Scope of Work & Installation Methodology

To satisfy strict regional building codes, NFPA 211 chimney safety standards, and national roofing manufacturer specifications, our licensed and insured restoration specialists executed a systematic, multi-phase technical protocol:

• Skylight Perimeter Inspection & Flashing Overhaul: Technicians inspected the existing skylight frame and glass seals. Damaged surrounding shingles were carefully removed to expose the mounting curb. High-tack self-adhering rubberized ice-and-water shield membrane was wrapped continuously around the curb-to-deck joint, followed by the installation of custom-formed aluminum head, sill, and interwoven side step flashings.

• Targeted Shingle Matrix Tear-Off & Subdeck Remediation: Weathered, lifted, and cracked asphalt shingles surrounding the skylight and chimney perimeters were systematically removed down to the plywood sheathing. Compromised subdeck boards were reinforced, covered with secondary waterproof underlayment, and woven with new premium dimensional architectural shingles secured using high-wind fastening patterns.

• Chimney Masonry Joint Rake-Out & Tuckpointing: Deteriorated and crumbling mortar joints along the brick chimney stack were raked out using specialized diamond-blade masonry tools. High-flexibility, water-resistant exterior Type N masonry mortar was firmly hand-troweled into the joints and tooled into a water-shedding concave finish to prevent freeze-thaw spalling.

• Custom Step & Counter-Flashing Encapsulation: Heavy-gauge metal step flashings were interwoven course-by-course with the new architectural shingles along the chimney flanks. A continuous horizontal reglet joint was cut into the brickwork to receive custom-bent metal counter-flashing, which was mechanically anchored and sealed with non-sag polyurethane lap sealant.

• High-Pressure Water Leak Audit & Magnetic Clean Sweep: A high-pressure water discharge audit was conducted across the skylight curb, chimney flashing seams, and repaired shingle matrix to verify absolute watertight performance. The work area underwent a full magnetic ground sweep to collect all metal debris and fasteners.

Results & Homeowner Value

By simultaneously overhauling the skylight perimeter, repairing the surrounding shingle matrix, and repointing and re-flashing the brick chimney, RH Renovation NYC permanently eliminated the property’s primary moisture vectors. The homeowners now benefit from a fully restored, aesthetically unified, and weather-tight roof assembly engineered to withstand harsh seasonal climates for years to come.
