When it comes to home comfort and energy efficiency, roof insulation plays a critical role. While homeowners often focus on walls, windows, and attics, the roof is a major factor in controlling heat gain and loss. Without proper insulation, your roof can become a gateway for energy waste, temperature fluctuations, and even structural damage.
At Koala Insulation of Chicago Western Suburbs, we specialize in helping homeowners protect their homes from top to bottom—starting with high-quality roof insulation. If you’re looking to improve your home’s energy efficiency and comfort year-round, here’s everything you need to know.
Why Roof Insulation Matters
The roof is one of the largest surface areas in your home that’s exposed to the elements. During the summer, sunlight beats down on your roof, radiating heat into your home. In the winter, warm indoor air rises and escapes through the roof if it’s not properly insulated.
Proper roof insulation from Koala Insulation of Chicago Western Suburbs can:
- Reduce heating and cooling costs
- Improve indoor temperature consistency
- Protect against ice dams and moisture issues
- Extend the lifespan of your roof and HVAC system
- Increase overall home value
How Roof Insulation Works
Roof insulation acts as a thermal barrier that slows the transfer of heat between your home and the outdoors. There are two main ways your roof can be insulated:
1. Attic Floor Insulation (Traditional Method)
This is the most common approach for homes with ventilated attics. Insulation is applied to the attic floor to prevent conditioned air from escaping into the attic. This method works well when the attic itself doesn’t need to be temperature-controlled.
2. Roof Deck Insulation (Unvented or Conditioned Attic)
In this setup, insulation is applied directly under the roof deck, making the entire attic part of the conditioned space. This is ideal for homes with HVAC equipment in the attic or for finished attic living spaces.
At Koala Insulation of Chicago Western Suburbs, we’ll evaluate your home and recommend the best approach based on your layout, HVAC system, and energy goals.
Best Types of Roof Insulation
Different insulation materials serve different purposes depending on your roof structure, climate, and budget. Here are the most common types we install:
1. Spray Foam Insulation
Spray foam is one of the most effective insulation types for roof applications. It expands to fill cracks and gaps, providing both insulation and air sealing in one step. Closed-cell spray foam is particularly useful for roof decks, offering a high R-value and moisture resistance.
2. Blown-In Insulation
Blown-in fiberglass or cellulose is a cost-effective option for insulating attic floors. It provides excellent coverage and is easy to top off if your existing insulation is below recommended R-values.
3. Batt Insulation
Pre-cut fiberglass or mineral wool batts are ideal for joist and rafter cavities. They are typically used in attic floors or unfinished attic walls and are known for their affordability and ease of installation.
4. Rigid Foam Board
Rigid foam boards offer high R-values and are often used in combination with other materials. These are ideal for attic access doors or roof retrofit projects.

Signs Your Roof Needs Insulation
Many homeowners don’t realize their roof insulation is lacking until they start experiencing comfort or energy issues. Here are some red flags to watch for:
- High energy bills despite moderate thermostat use
- Uneven indoor temperatures, especially upstairs
- Ice dams forming on the roof during winter
- Drafty upper-level rooms
- Overworked HVAC systems
- Moisture or condensation in the attic
If you notice any of these symptoms, it’s time to schedule an evaluation with Koala Insulation of Chicago Western Suburbs.

How Much Insulation Do You Need?
In Illinois, the recommended R-value for attic and roof insulation is R-49 to R-60, depending on your home’s age and heating system. Many older homes in the Chicago western suburbs have much less, meaning they’re losing significant energy through the roof.
Our team can measure your existing insulation and help you determine how much more is needed to reach optimal performance. We also check for air leaks, moisture intrusion, and proper attic ventilation to ensure your insulation performs at its best.
Don’t Forget About Air Sealing and Ventilation
Insulation alone won’t solve all your roof-related energy issues. Without proper air sealing, heated air can still escape through gaps and cracks. Likewise, without adequate ventilation, moisture can become trapped in the attic and lead to mold, rot, or ice dam formation.
At Koala Insulation of Chicago Western Suburbs, we take a holistic approach by sealing air leaks and ensuring proper attic ventilation before installing insulation. This ensures long-lasting performance and protects your investment.
