776 homes in Winfield, and the code rules that decide how much of an old roof has to come off.
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 (39% of Winfield’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 98% of Winfield’s homes were built before 1980, ask the contractor to count the layers before quoting.

Ice barrier
The state code’s ice barrier applies where the average January day is 25 °F or colder: Sussex County, per DCA Bulletin 07-3. Winfield is outside it, so whether to add one is up to you and the installer.

Checked against the code text on October 24, 2026. Code edition, permit and contract rules for the whole state: roof replacement in New Jersey.
Of 776 occupied homes in Winfield, 170 (22%) are owner-occupied. Counting by decade, 6% before 1940, 97% before 1960, 98% before 1980 of the housing was in place, and 1% dates from 2000 on. (ACS 2020–2024.)
The housing is 10% detached houses, 39% attached single-family houses (rowhouses, twins and townhouses), 51% buildings of two to four units.
With about two in five of homes attached, many roofs here meet a neighbor’s roof at a party wall. Say so on the call, and ask the contractor how the new roof will be tied in where it meets the house next door. New Jersey’s no-permit rule for reroofing covers detached houses only, so an attached house is outside it.
Of the 21 Union County municipalities on this site, Winfield has the largest share of homes built before 1980: 98%, against a county range of 65% to 98%.

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.
| Material | HUD useful life | Fits a house like | Watch for |
|---|---|---|---|
| Asphalt shingles | 20 years | Most pitched roofs; 10% of homes here are detached | Wind class set by the design wind speed (IRC Table R905.2.4.1) |
| Metal (standing seam, panels) | 50 years | Roofs that will carry solar later | A complete standing-seam system may go over the old roof (R908.3.1) |
| Slate | 75 years | Older houses; 6% here predate 1940 | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Low-slope roofs and rear sections (39% of homes here are attached) | Where the roof meets a wall or parapet |
