Ice Dams and Ventilation in Cicero
The town's own permit rule is what turns this into a decision rather than a default. Cicero states that no building permit is required for installing or replacing roofing provided no more than two layers are to be covered, which makes an overlay the path of least resistance on a town whose median construction year is 1980. An overlay changes nothing at the lower edge, though. Eave protection is an underlayment, laid on the deck before the covering, so putting new shingles over old leaves whatever is down there, or whatever is not, precisely as it was. Choosing to strip the roof instead is the moment that detail becomes available at all, and that choice is usually made on price without anyone explaining the trade.
What to weigh before you book
The second Cicero variable is exposure rather than age. The town runs north to the shore of Oneida Lake and holds the 4,991 acre Cicero Swamp Wildlife Management Area, which the state describes as low, wet terrain, so there is little to slow the wind and snow drifts rather than lying evenly. Drifted snow loads one slope and one valley far more than the rest of the roof, which is why the same two spots dam every year on a house where the rest of the roof clears. On stock of this vintage the attic is usually straightforward to correct: check that blown insulation has not been pushed over the soffit openings, that baffles hold the air path open, and that the bathroom fan actually discharges outside the roof space rather than into it.

Section R905.1.2 of the 2020 Residential Code of New York State requires that, in areas designated in Table R301.2(1) as having a history of ice forming along the eaves and causing a backup of water, an ice barrier be installed for asphalt shingles, metal roof shingles, mineral-surfaced roll roofing, slate, wood shingles and wood shakes. The barrier must be either two layers of underlayment cemented together or a self-adhering polymer-modified bitumen sheet, and it must extend from the lowest edge of the roof to a point not less than 24 inches inside the exterior wall line of the building. Detached accessory structures with no conditioned floor area are excepted.

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
If no permit is needed, is anyone checking what goes under my shingles?
No, and that is the point worth understanding. The exemption covers installing or replacing roofing where no more than two layers are being covered, so the specification is whatever your contract says it is. Write the eave detail into the contract, because there is no inspection standing behind it here.
Only one side of my roof grows ice. Why?
Usually because that side is where the snow ends up. With open ground and lake exposure to the north, wind moves snow onto one aspect and into the valleys rather than leaving it spread evenly, and a loaded slope over a warm attic gives ice more material to work with. It is also worth checking whether that side has less intake ventilation than the other.
