How Do I Know If My Insulation Needs Replacing?

Are you experiencing any problems with indoor air quality, temperature regulation, or heat transfer? Start with checking your attic or crawl space insulation. Improper insulation can directly affect your roof, home and quality of living.

A major amount of heat or air conditioning is lost through the roof in an uninsulated home. Insulating your loft, attic or flat roof is a simple and effective way to reduce heat loss and reduce your electric bills.

Annual Inspection

“Most experts, including those at the U.S. Department of Energy, recommend that you have your insulation inspected at least once a year. If your roof has had to be repaired or replaced because of leaks, you should definitely make sure to have an attic inspection. Mildew and mold can affect insulation materials and indicate that excessive moisture has been or is still in the area, which will severely affect the R-value of the insulation”, recommends Terminix.

Why Seal and Insulate?

Energy Star reports that “proper insulation and weather-stripping can reduce your monthly heating and cooling costs by up to 20 percent, and your annual energy bill by up to 10 percent. The EPA’s Energy Star program adds that adequate insulation is one of the most cost-saving home projects a homeowner can undertake. Air that leaks through your home’s envelope − the outer walls, windows, doors, and other openings − wastes a lot of energy and increases your utility costs. A well-sealed envelope, coupled with the right amount of insulation, can make a real difference on your utility bills.

Benefits of Insulation

There are many benefits of making sure you have the proper insulation in your home. Here are some of them:

  • Increased comfort in your home
  • Reduced noise from outside
  • Less pollen, dust and insects (or pests) entering your home
  • Better humidity control
  • Cost savings on electric bills
  • Better productivity from HVAC system
  • Reduce drafts 

Location of Insulation

Insulation is located in most homes in these places:

  • Attic
  • Crawl spaces
  • In-between walls


The International Association of Certified Home Inspectors states that spray foam insulation, wrap tape and house wrap insulation can last for more than 80 years. At the same time, cellulose, loose-fill, foamboard, loose fill and rock wool insulation can last up to 100 years.

Reduced Effectiveness

Several factors can reduce the effectiveness of your insulation:

  • Water Damage – Water damage from roof leaks can degrade the insulation and break it down faster. Normally there is no saving the insulation if it becomes damp or moist. If 
  • Mold – If mold forms on the insulation, it will not remain effective. 
  • Holes – Puncturing the insulation will decrease its effectiveness.
  • Settling – Loose-fill insulation may settle over time, leading to air leaks. When the thickness drops, the material is no longer as strong as it once was.
  • Incorrect R-Value – With the U.S. Department of Energy standards, some older homes do not have the correct R-value in place.
  • Rodents – Animals can set up home in your insulation and you’ll need to get rid of them plus access their damage. You may need to replace the insulation.
