When a home’s bathroom or dryer fan is vented into the attic, instead of outside, it adds to the moisture build-up that can occur on roof decks and attic surfaces. This causes mold which can lead to rotting. The solution is to both re-route the vent ducts outside, and to isolate the house from the attic in order to limit the amount of air escaping up there. Dr. Energy Saver of Connecticut installed our SuperAttic system which maintains roof ventilation without allowing exterior air to enter the attic space. This home now has a dry, healthy attic space and a more energy-efficient living area.
Consequences of Moisture in the Attic
Pictured is a moldy roof deck in a 10-year-old home. When warm, humid air leaks up into the attic and is cooled by the cold attic air, it condenses and causes condensation to accumulate on the bottom of the roof deck. Here you can see the resulting rusted nails which dripped the rusty water onto the attic floor. All of this wet wood can lead to mold and then rot and even mold spores being circulated throughout the house.
