Does your home need to withstand substantial amounts of snow for several months of the year? If so, a cold roof system may be the most durable and efficient roofing option. With a “cold roof,” air outside of your home are can freely flow under your roof’s sheathing, preventing unwanted leakage and damage. Here are three of the main reasons to consider a cold roof system:

Prevention of ice dams and leakage

With a typical “warm roof,” snow that hits the roof directly quickly begins to melt, run down the roof and freeze when it reaches the edge of the roof. When this happens repeatedly, ice dams are likely to occur which can add significant pressure to your roof’s core structure. Ice dams, also commonly referred to as icicles, can cause major damage to your shingles, as well as leaks inside your home. With a cold roof, your roof will remain a cool temperature in winter weather, preventing the freezing of snow and formation of ice.


Poor ventilation and insulation can cause severe condensation issues on your ceiling and walls, which can lead to damaged wooden fixtures or furniture, and even potential negative health effects. Excessive moisture can also lead to mold and decay, especially in areas of your home where moisture is most concentrated, including your kitchen and bathrooms. Because of how a cold roof works to prevent melting and refreezing, it can significantly reduce the incidence of humidity and moisture-related problems, reducing the likelihood of permanent damage to the interior of your home.

Easy installation

In many cases, a cold roof can be installed right over your existing roof. By stripping your roof down to its layer of plywood, your roofer will install several layers of new material, as well as an extra layer of insulation if needed. Through the cold roof system, there will be new space added between the first roof deck and the shingled roof layer, allowing air to easily come through in order to keep the top roof sheathing and shingles cold, while keeping your house warm.
