The roof is the uppermost part of any residential building, serving as the first line of defense against whatever the skies throw at its inhabitants. In many New York co-op and condo buildings, the roof is also a social space, complete with decking, planters, awnings, and sometimes even sun chairs or a hot tub. These roofs do double duty—and as such, they're subjected to far more wear-and-tear than their restricted-access counterparts.
Let’s take a closer look at roof decks—how they’re made, and what they mean for your building.
Nuts and Bolts
Decks in New York City are typically made out of concrete or wood. What a building decides to use depends on their current site circumstances as well as budgetary allowances.
“Many condos and co-ops will go with concrete because it is durable and can easily meet any building and fire codes,” says Michael DiMezza, president of Outside Design Build, Inc. in Brooklyn. “It puts up with the sun and cold well and comes in wide array of colors and textures. There are even some newer products that are softer on the foot. When you compare it with wood, it has greater longevity and less maintenance.”
DiMezza says that despite the pros of concrete, many boards still choose to use wood as their primary decking material.
