Sherman has 1,919 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 full replacement in Sherman 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). 66% of Sherman’s homes were built before 1980; many have been reroofed before.

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
Sherman’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).
