Half of the 937 homes in Norfolk were built before 1938. 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
The 25 percent line
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 Norfolk’s building official.
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). 79% of Norfolk’s homes were built before 1980, so count the layers before comparing quotes.
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.
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, which matters in a town where 52% of homes predate 1940.
Norfolk’s code design values are a 115 mph ultimate design wind speed and a 40 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).
Owners live in 579 of Norfolk’s occupied homes, or 81%. By year built, 52% before 1940, 61% before 1960, 79% before 1980; 8% went up in 2000 or later. (ACS 2020–2024.)
By building type: 88% detached houses, 6% buildings of two to four units.
19% of the homes in Norfolk are seasonal or occasional-use homes (ACS 2020–2024). If yours is one of them and you live elsewhere, the call still has to come from you as the owner.
On a house built before 1940, ask what the deck is (boards or plywood) and whether slate sits under the later layers: slate can’t be roofed over, and Connecticut’s joint-tape rule does not apply to narrow board decks.
Of the 26 Litchfield County municipalities on this site, Norfolk has the largest share of homes built before 1980: 79%, against a county range of 35% to 79%.
