Ice dam season in Twinsburg and the surrounding communities usually runs from late December through early March, with January and February the worst — that's when sustained cold and repeated Lake Effect snow events line up to create ideal ice dam conditions.
The trigger isn't just cold; it's the cycle. You need snow on the roof plus temperatures that swing above and below freezing, so the snow melts during the day and refreezes at the eave at night. Northeast Ohio's freeze-thaw pattern does exactly that for weeks at a time. The smart move is to handle insulation and ventilation in the off-season — fall is the time to fix it, not mid-storm.
