Do you have enough insulation in your attic?
Has the insulation in your attic settled and lost its R-value?
Are you losing heat through the roof because your attic insulation is not performing as it should?
If you answered yes to any of these questions, or you are not sure of the answer, you should call us for an evaluation to have your attic re-insulated or just have more insulation added.

Once you increase your attic R-value to the recommended level for your climate, you will save money month-to-month, and you will increase the overall comfort in your home.

The best way to determine if you need more insulation is to get access to the attic and inspect it for yourself. When you inspect your attic insulation, you should have approximately 8" – 15" of blown or loose insulation if your attic insulation is specified at R-30 or R-38.

There is a wide range mentioned because the actual number of inches required will depend on the R-value specification and the particular product or insulation material used. The table below will give you a general guideline for loose or blown-in insulation. Please note there may be difference to your attic insulation depending on when the insulation was installed, the type of product used and the quality of the installer.
Product type R-30 R-38 Color
Blown cellulose 8" 10" Gray or cardboard color
Blown fiberglass 12" 15" White, Yellow or Pink
