Metal roofing on commercial buildings in Jersey City takes a beating from two directions: summer heat cycling that expands and contracts panels, and winter freeze-thaw that works fasteners loose at the laps. We see the most failures at panel end laps, ridge caps, and around rooftop penetrations where HVAC curbs or conduit runs weren't properly flashed during a prior install. If you're seeing rust streaking below a seam or daylight through a screw hole in the deck, that's usually a fastener backing out, not a hole in the panel itself, which matters because it changes whether we're doing a spot repair or a full section re-fasten.
A lot of buildings around Journal Square and The Heights still run older exposed-fastener panel systems from the 80s and 90s. These need re-fastening or neoprene washer replacement on a cycle, and skipping that maintenance is the single biggest reason we get emergency leak calls after a hard freeze. Standing seam systems, more common on newer builds near Liberty Harbor and Hudson Exchange, don't rely on exposed fasteners and generally hold up longer, but they carry their own risk: if the clips aren't rated for the panel's thermal movement, you get oil-canning and eventually seam separation at the ridge.
On flat or low-slope commercial roofs where metal decking is the structural base but not the finished surface, we're often dealing with metal-and-membrane hybrid systems — a coated metal panel roof, or a membrane laid over standing seam. Coating breakdown at seams and pitch pans is the usual failure point there, and it's easy to misdiagnose as a membrane issue when it's actually the metal substrate corroding underneath. Any repair scope on these needs a magnetic thickness check on the deck before we commit to a patch versus a tear-off, especially on buildings near Liberty State Park where salt air off the water accelerates corrosion on unprotected fastener heads and cut edges.
Replacement decisions come down to panel gauge, coating condition, and how much of the substructure is still sound. We won't sell a full replacement when a section re-fastening and recoating gets you another decade — but we also won't patch a roof where the purlins are rusted through, because that's a structural liability, not a roofing one. Any reputable metal roof scope should include a written note on what we found underneath, not just what's visible from the ground.

Pricing
Metal roof repairs typically cost less than membrane repairs per square foot, but full replacement runs higher than a low-slope reroof — final price depends on panel gauge, access, and how much of the deck needs replacing.
