Nassau County Code Chapter 230 adopts the NY State Energy Conservation Code, which encourages reflective roofing on low-slope commercial roofs to reduce cooling loads and urban heat-island effects countywide.
Chapter 230 of the Nassau Administrative Code references the New York State Stretch Energy Code and base Energy Code. For low-slope commercial reroofs, prescriptive options include high solar reflectance index (SRI) membranes, increased insulation R-values, or cool-roof ratings from the Cool Roof Rating Council. Residential roofs are not generally required to meet cool-roof standards, but voluntary high-reflectance shingles qualify for utility rebates from PSEG Long Island. Permits are issued by local town and village building departments, not the county directly, with state energy code compliance verified at inspection.
Failed energy inspections delay certificates of occupancy; civil penalties for noncompliant roofing systems can reach hundreds per violation under local ordinances.
