The median home in Franklin was built in 1973; there are 734 of them. 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 whole new roof is more than that, so it goes to Franklin’s building official.
Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 62% of Franklin’s homes were built before 1980, ask what is under the newest layer.

Ice barrier
There is no local exception: the state table says “yes.” 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
Franklin’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).
