Was your home built in the 1960s or earlier? Do you have a second story room with knee walls or storage access panels down low on the wall? Are you having issues with ice dams at your home's eaves (near the gutters) in the wintertime? If yes, to any of these questions, you may be a candidate for a cold deck on your roof.

A roof cold deck is a layer of foam panel insulation installed above the roof deck or structural deck, creating a space between the insulation and the roof covering. This space is referred to as a "cold deck" because it is exposed to the colder outdoor temperature and is not heated by the building's interior.

In cold deck construction, the roof deck and the insulation are separate layers, with the insulation usually laid over a vapor barrier. Above the insulation, furring strips are installed to create a new air channel serving as your roof ventilation. Intake vents are installed at the home's eaves and a ridge vent is installed at your roof's peak. The roof covering is then installed on top of the insulation layer. This design helps to prevent the buildup of ice on your roof along with eliminating condensation on the underside of the roof deck, which can lead to mold growth, rot, and other moisture-related problems.
