The median home in Putnam was built in 1961; there are 4,403 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 full replacement in Putnam is past that line; the town building official issues the permit.
Layers
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. With 71% of Putnam’s homes were built before 1980, ask what is under the newest layer.

Ice barrier
The state’s climate table marks the ice barrier “yes” statewide. That is a self-adhering membrane, or two cemented layers of underlayment, from the eave to at least 24 inches inside the wall line (IRC R905.1.2).

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, which matters in a town where 40% of homes predate 1940.
Wind and snow
Putnam’s code design values are a 125 mph ultimate design wind speed and a 40 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).

Rules as read on October 24, 2026. Code edition, permit and contract rules for the whole state: roof replacement in Connecticut.
60% of the occupied homes in Putnam are lived in by their owners: 2,491 households, the people this line is for. By year built, 40% before 1940, 49% before 1960, 71% before 1980; 10% went up in 2000 or later. (ACS 2020–2024.)
By building type: 48% detached houses, 6% attached single-family houses (rowhouses, twins and townhouses), 32% buildings of two to four units.
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 15 Windham County municipalities on this site, Putnam has the 2nd largest share of homes built before 1980: 71%, against a county range of 38% to 81%.

A report says hail fell near Putnam, not that it damaged a roof. When wind or hail damage means a new roof.
HUD’s useful-life figures are for planning; a warranty is a separate promise. For Putnam’s houses: 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; 48% 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; 40% here predate 1940 | Sound slate can be reused (R908.5); broken slate cannot |
