New Milford has 11,641 homes, and half of them were standing by 1975. Below: what the code asks of a replacement here, the permit, and the town’s own records.
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 whole new roof is more than that, so it goes to New Milford’s building official.
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). 59% of New Milford’s homes were built before 1980; many have been reroofed before.

Ice barrier
The state’s climate table marks the ice barrier “yes” statewide. 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
New Milford’s code design values are a 115 mph ultimate design wind speed and a 35 psf ground snow load. At that wind speed the code calls for asphalt shingles labeled ASTM D7158 Class D, G or H (Table R905.2.4.1).

Useful life is HUD’s planning figure, not a warranty. More in the guides to shingles, metal, slate and flat roofs.

| Slate | 75 years | Older houses; 12% here predate 1940 | Can’t be roofed over; check the framing for the weight |
