Living in the Pacific Northwest means getting used to plenty of wet, rainy days. Your roof plays a big part in keeping your home and your family dry and comfortable. With that in mind, you may be wondering about moisture barriers under a metal roof.

If you are considering a roof replacement, a metal roof could be a great option. To avoid condensation buildup with your metal roof, you will need to have a moisture barrier in place.

When the air in the home is warmer than the air outside, condensation will collect. If the roof system is not ventilated properly, condensation can also collect. The metal roof panels on your roof deck can accumulate roof condensation and hold the moisture.

The speed with which metal roofs or metal buildings reach the dew point and condensation occurs can differ. It depends on air temperature, water vapor near the metal panels, the prevalence of warm air in and around your roof assembly, and other conditions.

Because evaporation can take a while, it could cause damage in the form of mold or corrosion. If you do not take care of it, it could even cause damage to the interior of your home. Metal roofing systems, roofing underlayments, vapor retarders, air barriers, and other roofing elements can cost-effectively inhibit moisture. And regardless of the specifics, most are better than fiberglass insulation.

To avoid this moisture under a metal roof, it’s important to talk to our experts at Mountaintop Metal Roofing about installing the right vapor barrier at the time of installation.

At the time of install, our team will focus on properly ventilating your roofing system, paying close attention to attic spaces or gaps between the ceiling and the roof. For ventilation, we will ensure it is designed to allow for maximum airflow. This will allow warm, moist air from the inside of the space to exit outside without condensation buildup. This can be done with ridge or soffit vents.

In addition to reducing the chance for mold or corrosion, ensuring that the right moisture barrier is in place will also help you reduce heating and cooling costs throughout the year. That’s because everything will be sealed properly, and no air will be unnecessarily leaked through cracks in your roof.
