New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.
This number connects homeowners who are planning a new roof or a full roof replacement with independent local roofing contractors. It is not for leak repairs or patch jobs. The call must come from the homeowner who decides on the roof. Calls may be recorded.
Permit
Under N.J.A.C. 5:23-2.7 a reroof of a detached one- or two-family house goes ahead without a permit or a notice to the construction office. Attached houses (3% of Ridgefield Park’s homes) and any work that touches the structure fall outside the rule.

Layers
Which layers may stay is a Rehabilitation Subcode question in New Jersey (the IRC definitions are deleted by N.J.A.C. 5:23-3.21), and this site has not read that subcode yet. With 93% of Ridgefield Park’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
Only Sussex County meets New Jersey’s 25 °F January test for a required ice barrier (N.J.A.C. 5:23-3.21; DCA Bulletin 07-3). For Ridgefield Park, ask whether the quote includes one anyway.

Checked against the code text on October 24, 2026. The state’s code edition and the rest of its rules: roof replacement in New Jersey.
60% of the occupied homes in Ridgefield Park are lived in by their owners: 3,072 households, the people this line is for. Counting by decade, 44% before 1940, 69% before 1960, 93% before 1980 of the housing was in place, and 3% dates from 2000 on. (ACS 2020–2024.)
The housing is 41% detached houses, 3% attached single-family houses (rowhouses, twins and townhouses), 26% buildings of two to four units.
Older houses hide their history: ask the contractor to confirm the deck (board or sheet) and every layer above it before pricing, because slate or two layers mean a full tear-off.
Of the 68 Bergen County municipalities on this site, Ridgefield Park has the largest share of homes built before 1980: 93%, against a county range of 30% to 93%.

Storm reports are what observers logged, not a measure of damage to any roof. When wind or hail damage means a new roof.
Lifespans come from HUD’s capital-needs table, not from a brochure. More in the guides to shingles, metal, slate and flat roofs.

|---|---|---|---|

| Metal (standing seam, panels) | 50 years | Low pitches and long runs | A complete standing-seam system may go over the old roof (R908.3.1) |
