When should an existing skylight be replaced?

A skylight may need replacement if it has cracked glazing, persistent condensation between panes, recurring leaks, deteriorated framing, or worn components that cannot be reliably repaired.

Can replacing a skylight help prevent roof leaks?

Replacing a damaged or outdated skylight and correctly installing its flashing and waterproofing can help reduce leak risks. However, the source of a leak should be inspected first because the problem may be in the surrounding roof rather than the skylight itself.

Skylight Replacement Project Completed Bronx NY

Existing Skylight Replacement Service in the Bronx

RH Renovation NYC completed a precision skylight replacement and roof-penetration weatherproofing project featuring removal of an aged, leaking skylight unit, structural timber rough-opening reframing, high-performance insulated skylight installation, and multi-tier perimeter step flashing integration for a residential home located in The Bronx, NYC. Roof penetrations on steep-slope and low-slope residential properties across The Bronx face severe environmental stress—including driving rains from seasonal nor’easters, extreme wind-shear uplift funneled through urban corridors, heavy winter snow accumulation, and intense summer thermal radiation.

When legacy skylight frame seals degrade, glazing units lose thermal seal integrity, or step flashings corrode, water migrates past the roof plane directly into interior ceiling framing. Uncontrolled leaks at skylight perimeters saturate attic insulation, rot structural header rafters, cause interior drywall staining, and lead to mold growth. This project was engineered to execute a complete structural and weatherproofing upgrade: removing the compromised skylight, reframing the rough opening with heavy-duty dimensional lumber, and installing an energy-efficient, weather-tight replacement unit with continuous ice-and-water shield flashing defense.

Comprehensive Scope of Work & Installation Methodology

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

Legacy Unit Demolition & Structural Substrate Audit: Technicians carefully dismantled the damaged skylight unit and removed surrounding shingle courses and flashings down to the bare roof deck. A structural audit revealed water-damaged perimeter framing, requiring targeted removal of decayed wood.
Structural Rough-Opening Reframing: Using high-grade structural dimensional lumber, technicians rebuilt and squared the skylight curb rough opening. Doubled header rafters and sistered framing members were installed to guarantee rigid support capable of carrying heavy snow loads and resisting wind-shear forces.
High-Efficiency Insulated Skylight Unit Mounting: A commercial-grade, energy-efficient replacement skylight—featuring low-E, argon-gas filled double-pane safety glass and an insulated aluminum frame—was set, leveled, and double-fastened to the newly engineered curb assembly.
Multi-Tier Waterproofing & Step Flashing Integration: Self-adhering ice-and-water shield membrane was wrapped continuously around the reframed curb and extending out onto the surrounding roof deck. Heavy-gauge aluminum step flashings were woven into the surrounding shingle courses, topped with a custom-formed head sill flashing to shed water cleanly away from upper frame joints.
Perimeter Interior Sealing & Exterior QA Audit: Polyurethane thermal foam insulation was injected into the perimeter rough-opening gap to stop air infiltration and eliminate thermal bridging. All flashing interlocks and sealant joints were verified, followed by a meticulous magnetic site cleanup.
