Deep River has 2,121 homes, and half of them were standing by 1974. 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.
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 Deep River 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). 57% of Deep River’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier
Connecticut answers “yes” to the ice barrier for every town. Membrane or doubled underlayment, eave to 24 inches inside the wall line (IRC R905.1.2), is a line on every quote here.

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
Deep River’s code design values are a 125 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).

A report says hail fell near Deep River, not that it damaged a roof. When wind or hail damage means a new roof.
Useful life is HUD’s planning figure, not a warranty. 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; 70% of homes here are detached | Class G or H at 125 mph design wind (IRC Table R905.2.4.1) |
| Metal (standing seam, panels) | 50 years | Low pitches and long runs | Standing seam that carries its own loads can skip the tear-off (R908.3.1) |
| Slate | 75 years | Older houses; 23% here predate 1940 | Can’t be roofed over; check the framing for the weight |
| Flat roof: EPDM or TPO | 15 years | Porches, additions, low-slope rears | Where the roof meets a wall or parapet |
