The median home in Oxford was built in 1986; there are 5,253 of them. What the code requires when that roof is replaced, and who signs off, is below.
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
Without a permit, Connecticut allows only:
Repairs that are limited to 25 percent of roof covering and building siding within one calendar year.
2022 CSBC, (Amd) R105.2, item 11
Replacing the whole roof crosses that line; Oxford’s building department issues the permit.
Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 38% of Oxford’s homes were built before 1980, ask what is under the newest layer.

Ice barrier
Connecticut answers “yes” to the ice barrier for every town. It runs from the eave to 24 inches inside the exterior wall, more on steep roofs (IRC R905.1.2); check that the quote lists it.

Deck joints
Connecticut adds a 4-inch self-adhering strip over all joints of a plywood or OSB deck ((Amd) R905.1.1). It is not needed under a fully adhered membrane, or on board decks under 3 feet wide.
Wind and snow
Oxford’s code design values are a 120 mph ultimate design wind speed and a 30 psf ground snow load; it is in Connecticut’s hurricane-prone region. At that wind speed the code calls for asphalt shingles labeled ASTM D7158 Class G or H (Table R905.2.4.1).

Of 5,046 occupied homes in Oxford, 4,564 (90%) are owner-occupied. Counting by decade, 9% before 1940, 19% before 1960, 38% before 1980 of the housing was in place, and 32% dates from 2000 on. (ACS 2020–2024.)
The housing is 89% detached houses, 7% attached single-family houses (rowhouses, twins and townhouses).
32% 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 27 New Haven County municipalities on this site, Oxford has the smallest share of homes built before 1980: 38%, against a county range of 38% to 87%.

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.
Since 2006 the National Weather Service has logged hail of 1 inch or larger on 13 separate days within 10 miles of Oxford; the largest was 1.75 in on October 4, 2010. The most recent was August 3, 2024.
That is more hail days than 87% of the places in the state on this site.
At the county level, Oxford shares New Haven County’s record of 12 storm disaster declarations since 2006, the newest DR-4820 (Severe Storm, Flooding, Landslides, and Mudslides, September 2024). (OpenFEMA.)
Storm reports are what observers logged, not a measure of damage to any roof. When wind or hail damage means a new roof.
HUD’s useful-life figures are for planning; a warranty is a separate promise. For Oxford’s houses: 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; 89% of homes here are detached | Class G or H at 120 mph design wind (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; 9% here predate 1940 | Never a base for a new layer (R908.3.1.1); heavy |
| Flat roof: EPDM or TPO | 15 years | Additions and porch roofs | Coating is not a replacement |
