Signs your Attic Insulation is Inadequate

  • High costs for heating and cooling
  • Roof is leaking
  • Ice build-up on a rooftop
  • Icicles on the fascia or eaves-troughs
  • Cold areas in the home
  • The roof is aging prematurely

Before you go ahead and install insulation, you need to have roof leaks repaired, direct exhaust fans and vents to the home’s exterior, box out light fixtures, and make sure you take all necessary safety measures.

Whether the building of the unvented attic takes place in a warm or cold climate zone location, there are some design considerations that are consistent throughout, while other considerations require a greater understanding of the materials that could be used based on the climatic environment.

Do I Need Attic Insulation?

If you think you’re among the 90% of US homes that are under-insulated, performing a simple insulation inspection will help you determine your insulation needs. Having the correct amount of attic insulation can help you maintain a comfortable temperature throughout your home and help save money on your energy bills—plus, prevent major issues like ice dams in the winter.

Inspecting your attic insulation

First things first, you need to go up into your attic, inspect the condition of the insulation, and calculate the current level of insulation. Your attic should have a certain amount of insulation in it, and the recommended level of insulation for your attic is dependent on where you live.

If your insulation doesn’t measure up and you need more, installation can be done as a weekend DIY project or you can call a professional installer to handle the job.
