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 Plainville’s building official.
Layers
A new roof may go over one existing layer; with two or more, or over slate, clay or cement tile, everything comes off to the deck (IRC R908.3.1.1). 66% of Plainville’s homes were built before 1980; many have been reroofed before.

Ice barrier
The state’s climate table marks the ice barrier “yes” statewide. 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
Plainville’s code design values are a 120 mph ultimate design wind speed and a 35 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).
