How To Stop Condensation In Your Attic

Attic Condensation Is A Serious Warning Sign

Condensation in the attic is a huge red flag, indicating problems with the home’s thermal envelope. It occurs when heated air comes into contact with cooler air or surfaces, resulting in moisture droplets on the hard surfaces. 

When moisture-rich humid air comes into contact with cooler surfaces, the water vapor condenses and becomes a liquid. This can happen when you exhale into a cool mirror or window, or when you put cold sunglasses from your automobile on your warm face.

    Primary Sources Of Attic Condensation

    Outdated insulation, drafts, inadequate ventilation, and leaking roofing are the most common causes of condensation in attic areas. Upgrading insulation can immediately improve attic and overall home conditions, whereas air sealing reduces condensation by removing deteriorated weather stripping and tightening seals around outside penetrations.

    Moisture In The Attic Can Be Identified By:

    • • Visible signs of moisture or damage in the attic.
    •  
    • • Drops on the underside of the roof or evidence of watermarks on the roof.
    •  
    • • Condensation on interior windows or dripping from ceiling vents.
    •  
    • • Evidence of mold or mildew in interior walls and ceiling surfaces (unrelated to any plumbing leaks).
    •  
    • • A wet or moldy smell coming from the house or attic.
    •  
    • • Fluctuating temperatures throughout the home.

    Replace Old Inefficient Insulation

    Your insulation may be letting conditioned air into unconditioned spaces if it is old, damaged, or poorly installed. This eventually results in moisture and uneven heating throughout the residence. 

    You can determine whether or not insulation is adequate by making an appointment for a FREE INSPECTION with a licensed insulation technician from Comfort 1st Insulation. Overall home conditions are immediately improved by replacing the insulation.

    Thoroughly Air Seal

    Depending on the season, warm or cold air collides in the attic when there are air leaks. Warm air that is heavy with moisture condenses on hard surfaces throughout the summer. More condensation occurs in the winter months when hot air contacts a chilly roof or metal parts.

    Attic condensation can be reduced by replacing deteriorated weather stripping and strengthening seals around external penetrations. Contact the certified technicians at Comfort 1st Insulation in order to properly air seal your home, establishing comfort and savings.

    Install Proper Ventilation

    An attic space can only be healthy if the proper amounts of ventilation, air sealing, and insulation are used. There are several ventilation methods that operate in order to balance humidity and airflow through and around your roof and attic, depending on your home’s orientation on the lot, location, and roof design.

    If you need to replace insulation or upgrade your roof, installing proper ventilation is advised. It also is necessary to have an expert evaluate your attic and determine whether your current ventilation sources are functioning properly.

    Repair Roof Leaks

    If your deck has deteriorated over time or if your roof leaks, condensation is more likely to occur. Most roofs need to be replaced around every twenty years, or sooner if they aren’t properly maintained, unless they are made of metal.

    Attic condensation can lead to several problems, including compromising whole-home energy efficiency, increasing energy spending on heating and cooling, leading to more expensive HVAC maintenance and repairs, and compromising indoor air quality. Moisture control issues create unnecessary temperature and humidity fluctuations, causing HVAC systems to work harder and more frequently to regulate interior comfort. 

    This results in higher energy spending, as heating and cooling account for nearly 50% of utility costs. Additionally, condensation can cause mold and mildew infestations, releasing spores that can cause respiratory issues for residents. Therefore, it is crucial for homeowners to maintain moisture-free attics to maintain optimal indoor air quality.
