A mill town built on a 70-foot drop in the Mohawk
Cohoes Falls, the second-highest waterfall in New York State, gave the city both its name and its industry -- water rights first went to the 1811 Cohoes Manufacturing Company, then to the Cohoes Company in 1826 after the Champlain and Erie canals arrived, and by 1872 the Harmony Mills complex built on that power was the largest cotton-mill operation in the world. The rowhouses and mill-adjacent housing built through that boom left Cohoes with a dense stock of steep-pitched, closely spaced rooflines.
Ice damming on Cohoes' older, steep-pitched roofs
Roofs framed during the 1830s-1870s mill era were typically cut steep to shed snow fast, but decades of re-roofing over the same original sheathing without matching ventilation upgrades leaves plenty of these houses prone to ice damming once Capital District winters deliver one of their annual double-digit-inch snow events. Chimneys and party-wall flashing from that era are also common trouble spots that a modern subdivision roof simply doesn't have.

What to have ready for a roof estimate
Know roughly how old the current roofing is, whether you've had ice damming or attic leaks in past winters, and whether the deck has been re-covered more than once. Ask for a straight answer on ventilation, not just shingle brand.
