Ceiling Moisture Problems Using Loose Insulation

Loose fill insulation is commonly blown into attics and crawl spaces to help keep the home's heat from escaping. In a perfect setting, it works quite well. However, if the insulation is installed improperly, or if there are severe roof leaks, loose fill insulation can cause ceiling moisture issues, and these issues can be severe.
  1. Installation Issues

    • Fluffing is unfortunately a common practice in the insulation business. What this means is that a smaller quantity of insulation is used in the space, and then fluffed up to make it look like more is actually there. This practice is not only harmful to consumers in terms of expense, but can cause moisture problems in the future. Densely packed loose insulation that is installed properly is less likely to develop moisture issues.

    Roof Leaks

    • If you have a roof leak, the loose insulation in your attic or crawl space is going to get wet. As it gets wet, it swells and becomes heavier. Even small leaks can pose a problem if you live in an area that gets a lot of rain or snowfall. Over the years, this moisture will build up, causing not only issues with weight but also harmful mold and bacteria. Attics and crawl spaces should be regularly inspected to determine if any leaks are present. If they are, they need to be fixed immediately.

    Ceiling Damage or Collapse

    • Loose insulation that is waterlogged will be much heavier than the original dry material. This can cause issues with ceiling damage and even potentially a collapse. Such a collapse can be deadly if people are in the room when the ceiling goes. Moist insulation is a problem that cannot be ignored. Unfortunately, you may not notice the problem until the ceiling starts displaying water damage and cracks. Regular inspections can help catch these issues before they start.

    Preventing the Problem

    • When you have insulation blown-in to your attic or crawl space, ask the contractor how many bags will be used. Be present for the installation and count the bags. If the number is light, your insulation may have been "fluffed." Repair roof leaks immediately and stay alert to potential problems in your attic and crawl space. If you have an older roof, consider replacing it or at least have the flashing redone to help stop leaks before they occur.
