Potential Signs of Attic Condensation

With a few winter storms recently hitting our area, and more in the upcoming forecasts, the chances for roof leaks in the coming weeks continues to be high. Another source of moisture issues is condensation and Fall, Winter and Spring is when we see it the most. Condensation occurs when moisture in warm air is squeezed out by cold air or cold surfaces. Condensation can cause rotting and mold, many times resulting in serious damage over time. Poorly routed bathroom or laundry room vents can cause condensation, or maybe the entire attic itself is not insulated properly. Warm air escaping from the house into the attic in areas like attic stair openings, can lights or tongue and groove ceilings can be culprits as well. Another more recent problem that could be causing attic condensation is whole-house humidifying systems. Oftentimes these can be set to run too high, causing condensation to build in the attic. Regardless of the cause, noticing the signs of a possible roof leak or attic condensation is key for minimizing damage.

Potential Signs of Attic Condensation

• Rusty nail points or water droplets on the nails inside the attic.
• Water marks on your ceiling or walls
• Visible mold or stains inside the attic – usually on the North side of the attic.
• Moisture on glass, metal, or flat surfaces, such as skylight glass, skylight flashing, chimney flashing, pipe collars, etc.
• Wet/damaged sheathing on roof

If you believe you have any of these signs, it is imperative to try to identify the source of what is causing the condensation to happen.

Tips to Stop Condensation

• Improving overall insulation and ventilation in the attic
• Run a dehumidifier to help stave off some of the lighter attic condensation
• Turn off humidifiers
• Find out where your bathroom vents are routed to make sure they are venting to the outside, (sometimes they become loose and disconnected), and make sure to run the bathroom fan during and for 5 to 10 minutes after a shower.
• Add insulation and weather stripping to attic access openings
