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 West Hartford’s building official.
IRC R908.3.1.1 forbids roofing over two existing layers, over slate or tile, or over a water-soaked roof. 87% of West Hartford’s homes were built before 1980, so count the layers before comparing quotes.
There is no local exception: the state table says “yes.” It runs from the eave to 24 inches inside the exterior wall, more on steep roofs (IRC R905.1.2); check that the quote lists it.
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 28% of homes predate 1940.
West Hartford’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).
