Ice Dams and Ventilation in Clay
Clay has the youngest housing in the county, a median construction year of 1978 and just 3.2 percent of units built in 1939 or earlier, which moves the whole investigation off the roof and into the ceiling below it. These are attics with blown insulation lying over drywall, and the heat paths are the ones a builder of that era left behind: an uninsulated hatch, open plumbing and flue chases, recessed fittings punched through the ceiling plane, and a bathroom fan ducted up into the roof space rather than out through it. Each of those warms the deck, and a warm deck melts snow that then runs to an overhang sitting at outdoor temperature. None of it is roofing, and all of it is cheaper to correct than any covering.
What to weigh before you book
The permit position needs a phone call rather than a search. The Town of Clay's published list of projects requiring a building permit names new buildings, all additions and alterations to existing buildings, garages and barns, pools, sheds, decks and porches, fences, signs, fireplaces, stoves and demolition, and roofing and re-roofing are not on that list at all. That is an absence rather than a stated exemption, and it is not the same thing. Call Planning and Development before work is booked, and call without fail if any part of the scope becomes structural repair to the deck or rafters, because the alterations line plainly does reach that. On the building side, decide the order of work: sealing the ceiling plane first, then insulation, then ventilation matched at intake and exhaust. Reversing that order means paying to vent away heat you are still buying.

Section R806 of the Residential Code of New York State requires ventilation of enclosed attics and enclosed rafter spaces, and requires not less than one inch of clear space between the insulation and the roof sheathing where eave or cornice vents are installed.

What Ice Dams and Ventilation involves
An ice dam is a heat problem that shows up as a water problem. Heat escaping into the attic warms the roof deck, snow melts on the upper slope, the meltwater runs down to the cold overhang beyond the heated walls and refreezes, and the ridge of ice that grows there holds standing water back under the covering until it finds a way in. Syracuse averages 123.8 inches of snow a year, an inch or more sits on the ground on around 60 days of a normal winter, and the temperature crosses freezing in both directions roughly 84 days a year. Those three numbers are the whole mechanism. The New York State Department of Health names ice dams and insufficient attic ventilation among the moisture sources that cause mold in homes, which is why this work is a mix of air sealing, ventilation, eave detailing and drainage rather than roofing alone.

Frequently Asked Questions
My house is only from the 1980s. Why does it dam at all?
Age has little to do with it. What matters is how much warm air escapes into the attic and whether the roof space can get rid of it. A leaky hatch, recessed fittings and a bath fan blowing into the roof will warm a modern deck just as effectively as an old one, and blown insulation slumped over the soffits removes the intake that would otherwise carry the heat away.
Does the town need to know I am having this done?
Its published permit list does not mention roofing or re-roofing either way, which is a silence rather than a written exemption, so ask Planning and Development directly. If the job turns into replacing decking or repairing rafters, treat that as an alteration and get the town's answer in writing first.
