Half of the 5,454 homes in Avalon were built before 1988. The rules below decide how much of the old roof has to come off and what goes under the new one.
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.
The rules for a reroof in Avalon
Permit
None for a detached one- or two-family house
New Jersey treats a new covering on a detached one- or two-family house as ordinary maintenance: no permit, no notice (N.J.A.C. 5:23-2.7). In Avalon, 67% of homes are detached. An attached house, or work on rafters and beams, is not covered.
New Jersey deletes the IRC’s reroofing definitions (N.J.A.C. 5:23-3.21(c)2.xxii); its layer rule for existing houses is in the Rehabilitation Subcode, which this site has not read yet. 34% of Avalon’s homes were built before 1980: ask how many layers yours has and whether the price is for a tear-off to the deck.
The state code’s ice barrier applies where the average January day is 25 °F or colder: Sussex County, per DCA Bulletin 07-3. Avalon is outside it, so whether to add one is up to you and the installer.
Owners live in 731 of Avalon’s occupied homes, or 93%. By year built, 10% before 1960, 34% before 1980; 37% went up in 2000 or later. (ACS 2020–2024.)
By building type: 67% detached houses, 23% attached single-family houses (rowhouses, twins and townhouses).
81% of the homes in Avalon are seasonal or occasional-use homes (ACS 2020–2024). If yours is one of them and you live elsewhere, the call still has to come from you as the owner.
37% of homes here were built in 2000 or later. HUD’s useful-life table gives an asphalt-shingle roof 20 years, so roofs on houses from the early 2000s are reaching that age.
Of the 13 Cape May County municipalities on this site, Avalon has the 12th largest share of homes built before 1980: 34%, against a county range of 23% to 69%.
Median built: median year the homes were built. Before 1980: share of homes built then. Owners: share of homes that are owner-occupied. Row, twin: share of homes that are rowhouses, twins or townhouses. Census ACS 2020–2024. Hail days: days with hail of 1 inch or larger within 10 miles, 2006–2025, NOAA Storm Prediction Center.
