Anytime moisture is trapped in or under your roof there is cause for concern. Condensation typically occurs when warm air from inside the home rises up to the roof. When that warm air meets the cool air outside, condensation forms. If there is nowhere for the water to go it can seep into the wood and other materials in your roof, or even your walls, causing mold growth and potential structural damage. So, if you’re wondering if condensation is a threat to your roof take it from the expert roofers at PJ Fitzpatrick, the answer is “Yes.”
Common Causes of Roof Condensation
When condensation is forming on your roof or in your attic, there are a few potential causes. Ultimately the issue is related to the temperature of the air in your attic or underneath your roof. Making sure your home is properly insulated and that your attic is appropriately ventilated are the first steps to keeping your roof free from condensation.
Like you, your home needs to breathe to function properly. Ridge and soffit vents allow air to circulate under your roof which helps dissipate extreme temperatures. When your roof is ventilated, your home can maintain a more consistent temperature that will improve its energy-efficiency and keep condensation from forming and becoming a threat to your roof.
If your home is uninsulated or under-insulated, heat will escape through your walls and roof. Not only does this loss of heat create the potential for condensation on your roof but it will also cause your HVAC system to work overtime to regulate the temperature, raising your energy bills. When your home is properly insulated, you’ll be comfortable inside and protected from the extreme temperatures outside.
Missing Vapor Barrier
Another often neglected cause of condensation that can be a threat to your roof is a missing vapor barrier under your shingles. A roof that is installed correctly should have a thin underlayment beneath the shingles that serve as a vapor barrier. This keeps moisture from seeping into the roof deck boards.
