Ice Dams and Ventilation in Manlius
The ice barrier requirement is not a statewide switch, which is why the answer to it has an address attached. Section R301.2 leaves the ground snow load, wind speed, frost line depth, air freezing index and the ice barrier requirement to be established by the local jurisdiction and set out in Table R301.2(1), and the state technical bulletin adds that where an authority having jurisdiction spans several cities, towns or villages, the data has to be filled out for each municipality individually. In Manlius that sentence has teeth, because the Town of Manlius and the Village of Manlius are separate governments running separate offices, the town counter at 301 Brooklea Drive in Fayetteville and the village office on Arkie Albanese Avenue.
What to weigh before you book
So the first call is not to a roofer, it is to whichever of those two offices covers the property, with one specific question: has YES been entered in the ice barrier underlayment column for this municipality. The state instructs each authority to enter it where there is a history of local damage from ice damming, and that entry is what makes the requirement bite. The same boundary predicts the building itself. Across the Town of Manlius only 11.2 percent of housing units were built in 1939 or earlier, half the county share of 22.6 percent, so the town side is mainly post-war stock where the attic is accessible and the fix is sealing and balanced venting. The older pre-war housing sits in the village core, where narrow eaves, plank decking and knee-wall spaces make both the ventilation and the eave detail a bigger piece of work than the same job two miles away.

New York State Department of State Technical Bulletin TB-1009-RCNYS instructs each authority having jurisdiction to fill the ice barrier underlayment required column of Table R301.2(1) with YES where there is a history of local damage from the effects of ice damming, per footnote h to that table, which then triggers section R905.1.2.

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
Which office do I ask, the town or the village?
Whichever one your address sits in, and they are genuinely separate governments. A village address files with the village office on Arkie Albanese Avenue and never with the town, whose counter is at 301 Brooklea Drive in Fayetteville. Getting this wrong costs days at the exact point in the year when crews are already booked.
Can two houses this close together really have different requirements?
On this particular item, yes. The local criteria table is filled in municipality by municipality, and the state bulletin is explicit that an authority covering several places has to complete the data for each one separately. That is why the honest answer to whether an ice barrier is required is always ask your own code office.
