Edison, NJ
Roofing in Edison, NJ: A Big Township With Its Own Code Office
Edison is a township of its own, the largest in Middlesex County with 107,588 people at the 2020 count, and it borders Woodbridge Township along the west side of Colonia and Iselin. Roof paperwork questions go to Edison's own Code Enforcement office on Municipal Boulevard, not to Woodbridge. The Census median build year is 1975, give or take 2, sixteen years newer than Colonia's. That office's page is summarized under Papers to ask for.
Edison's edge along Woodbridge
Edison borders Woodbridge Township, where Colonia and Iselin sit, and Clark in Union County. Oak Tree Road runs about a mile and a half along Route 27 through Edison and Iselin, and the Metropark office park reaches across the line from Iselin. The township hall and the Code Enforcement office are both at 100 Municipal Boulevard, Edison 08817.
The houses
Census Bureau ACS figures for 2020-2024 count 39,225 homes in Edison.
The 1980s are the biggest decade, with 9,544 homes, followed by the 1960s with 6,886 and the 1950s with 6,378. About 10,052 homes, 26 percent, were built before 1960, a much smaller share than in Colonia or Iselin. Renters live in 15,020 of 38,098 occupied homes, about 39 percent. A renter with a roof problem calls the landlord or property manager first.
