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 full replacement in Vernon is past that line; the town building official issues the permit.
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. 66% of Vernon’s homes were built before 1980, so count the layers before comparing quotes.
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.
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.
Vernon’s code design values are a 120 mph ultimate design wind speed and a 30 psf ground snow load. At that wind speed the code calls for asphalt shingles labeled ASTM D7158 Class G or H (Table R905.2.4.1).
