Ice Dam Prevention, Eave Protection and Attic Ventilation in Baldwinsville, NY
Take the 1970s streets that put the village median construction year at 1975. A first asphalt covering, a second one laid over it somewhere in the 1990s, and now a homeowner watching the same two or three places grow ice every February.
Ice Dams and Ventilation in Baldwinsville
Take the 1970s streets that put the village median construction year at 1975. A first asphalt covering, a second one laid over it somewhere in the 1990s, and now a homeowner watching the same two or three places grow ice every February. What that overlay did not do was change anything at the lower edge of the roof, because eave protection is an underlayment that goes on the deck before the covering, so a second layer laid over the first left the original detailing exactly where it was. With two applications already up, section R908.3.1.1 does not permit a third recover in any case, which means the tear-off is both the compliant route and the first real opportunity this roof has had to fix its eaves.
What to weigh before you book
That timing is the whole argument for doing this as one job rather than two. Membrane at the eaves and valleys, metal valley linings and a drip edge and gutter arrangement that assumes ice all cost a fraction installed while the covering is off compared with revisiting them later as their own operation, so if a replacement is already close, the ventilation survey belongs in the same visit. On the older canal-era core, where 20.6 percent of village units were built in 1939 or earlier, the same section bites for a different reason, since a recover is barred where the existing covering is slate, clay, cement or asbestos-cement tile or where the roof is water soaked. On filing, the village straddles the Towns of Lysander and Van Buren with the Seneca River running through the middle of it, but a village address goes to village code enforcement rather than to either town.

Section R908.3.1.1 of the residential code adopted in New York State does not permit a roof recover, that is a new covering laid over the existing one, where the existing roof already has two or more applications of any type of roof covering.

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
Can I just have another layer put on and deal with the ice separately?
Not where two coverings are already in place, because the code does not permit a recover over two or more applications. Count the layers at the eave first. If there are two, the choice is not overlay versus tear-off, it is tear-off, and that is also the point at which the eave detail can finally be built properly.
The village sits in two towns. Where does the paperwork go?
To the village. Baldwinsville straddles Lysander and Van Buren, which confuses plenty of first-time callers, but a village address files with village code enforcement. Ask them directly what they require for a re-roof, since the state neither exempts roofing outright nor requires a permit for it by name.
