Project: New Skylight Installation and Aluminum Painting Service

RH Renovation NYC completed a specialized dual-scope low-slope roofing upgrade featuring custom insulated skylight penetration flashing and a comprehensive solar-reflective aluminum roof coating application for a property located in the Bronx, NYC. Low-slope and flat roof assemblies across the Bronx’s dense urban environment endure severe environmental pressures—including intense summer solar thermal gain, ultraviolet (UV) membrane degradation, driving nor’easter rains, and severe winter freeze-thaw cycles that induce heavy expansion and contraction stress on roof penetrations.

Adding new skylight penetrations to a flat roof requires advanced hydrodynamic engineering to ensure that framing openings are completely watertight, thermally broken, and resistant to standing water or ice dams. Furthermore, protecting the surrounding elastomeric or bitumen roof surface with a high-albedo metallic coating reflects harmful solar radiation, substantially lowers upper-floor cooling loads, and extends the operational lifespan of the entire roof assembly.

Comprehensive Scope of Work & Installation Methodology

To ensure absolute leak protection, optimized natural daylighting, and strict compliance with New York City Department of Buildings (DOB) energy and structural codes, our licensed and insured Bronx specialists executed a rigorous, multi-phase technical installation protocol:

• Structural Roof Deck Opening & Skylight Curb Framing: Technicians carefully laid out and framed structural roof deck openings, constructing custom pressure-treated, insulated curb assemblies raised above the primary roof plane to elevate skylight frames well above standing water or winter snowpack lines.

• High-Performance Skylight Unit Mounting: Energy Star-rated, double-paned insulated glass skylight units were mechanically anchored to the timber curbs. The glass assembly features low-emissivity (Low-E) coatings and argon gas fills to minimize solar thermal heat gain while maximizing natural daylight transmission.

• Hydrodynamic Penetration Waterproofing & Flashing Integration: The skylight curb transitions were completely wrapped with self-adhering modified bitumen or elastomeric flashing membranes, fully integrated with the surrounding roof substrate. Custom heavy-gauge counter-flashings and industrial-grade lap sealants were installed to permanently lock out wind-driven rain and melting ice.

• Substrate Preparation & Washing: The entire flat roof surface was thoroughly cleaned of urban soot, debris, and atmospheric contaminants, followed by localized seam inspections and surface repairs to establish an optimal bonding face for the coating system.

• Reflective Aluminum Paint Application: A premium-grade, heavy-bodied reflective aluminum coating was uniformly applied across the entire flat roof field. This metallic-pigmented barrier forms a bright, UV-resistant shield that reflects solar heat away from the building envelope, prevents thermal shock cracking, and cures into an added protective weathering layer.

• Final Quality Assurance & Compliance Audit: A thorough multi-point inspection verified that all skylight seals, curb flashings, glass seals, and coating mil thicknesses met strict manufacturer warranty standards and local building codes, followed by a complete site cleanup.

Results & Property Owner Value

The completed project equips the Bronx property with brilliant, natural interior daylighting while significantly fortifying the flat roof’s thermal envelope. By pairing custom curb-mounted skylight flashings with a high-albedo aluminum coating, RH Renovation NYC successfully eliminated roof penetration leak risks, reduced summer cooling demands, and extended the overall durability and value of the roofing asset.

RH Renovation experts installed new skylights for one of our clients in the Bronx, NYC. After the skylight installation we fully completed the aluminum painting. Check the below images to view our job and contact us if you have any questions.
