Union City is, by some measures, the most densely populated city in the United States — about 68,000 residents packed into 1.3 square miles on the Hudson Palisades. The housing is overwhelmingly multi-family and rental, built largely in the mid-20th century, and it's almost entirely flat and low-slope. This is membrane-roofing country, not shingle country.
Housing in Union City
Wall-to-wall multi-family: brick and frame three- and four-families, mid-century apartment buildings, and mixed-use, nearly all with flat or low-slope roofs. Parapet walls, shared walls, roof drains, and very tight access between attached buildings define every job here.
What we most commonly find on Union City roofs
- Failed flat-roof seams on multi-family and mixed-use buildings
- End-of-life built-up tar-and-gravel roofs
- Parapet wall, coping, and roof-drain flashing failures
- Ponding water on under-sloped roofs
- Coordination across multi-unit ownership
Why we work in Union City
Union City is pure flat-roof work — welded TPO and EPDM seams, parapet flashing, and real drainage — which is exactly the membrane roofing we specialize in across Hudson County.
