Have you noticed that your metal roofing is “sweating” on the inside? Condensation issues plague homeowners from Clarksville to Nashville, causing water damage, rotting wood, and encouraging mold and mildew growth. The fact is, condensation in the attic is simply more noticeable with metal roofing, but any type of roof is susceptible.

Why does condensation occur?

There are two ingredients that cause a roof to sweat: humidity and a temperature difference. Humid Tennessee air can enters your attic through vents. By itself, this isn’t a problem. However, if the air in your attic is kept at a warmer temperature as the air on the outside of your roof cools to below the air’s dew point, condensation will occur at the boundary between the two temperatures.

How can I stop condensation on my attic’s roofing?

Proper ventilation in your attic is a must to ensure that air can freely move in and out of the space. This helps to ensure that air rich in moisture is not trapped there. To address the temperature differences that cannot be avoided, your attic must also be properly insulated. Expanding foam is one option that works well, also serving as a decent moisture barrier. Consult an experienced roofing contractor to ensure that correct quantities, materials, and placement of insulation are being used to properly control your attic’s temperature.
