Fairfield has 22,537 homes, and half of them were standing by 1960. 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
A full replacement in Fairfield is past that line; the town building official issues the permit.
Layers
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). With 74% of Fairfield’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. That is a self-adhering membrane, or two cemented layers of underlayment, from the eave to at least 24 inches inside the wall line (IRC R905.1.2).

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
Fairfield’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).

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 7 separate days within 10 miles of Fairfield; the largest was 1.5 in on October 4, 2010. The most recent was May 15, 2018.

Fairfield County has had 11 federal major-disaster declarations for storms since 2006; the latest was 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.
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 |
|---|---|---|---|

| 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; 19% here predate 1940 | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Additions and porch roofs | Where the roof meets a wall or parapet |
