Benefits of Attic Roof Insulation

Proper attic roof insulation offers measurable improvements in energy usage, comfort levels inside your home, and long-term expenses. We focus on these key areas to ensure our clients in Glendale, CA, gain the most from their investment.

Enhanced Energy Efficiency

Attic roof insulation reduces heat transfer between your attic and living spaces. This means your heating and cooling systems work less to maintain desired temperatures.



We typically recommend insulation levels of R-30 or higher in Glendale’s climate to maximize thermal resistance. This helps cut down on energy waste during hot summers and cooler winters.

Improved Indoor Comfort

Insulation stabilizes indoor temperatures by blocking outside heat in summer and retaining warm air in winter. This creates a more comfortable living space year-round.



It also helps manage moisture and reduces cold spots in rooms underneath the attic. Our installations focus on even coverage and proper ventilation within the attic to avoid condensation and mold risks.

Long-Term Cost Savings

Investing in attic roof insulation yields significant savings on energy costs over time. Reduced demand on HVAC systems decreases wear and tear, extending their lifespan.



We use materials that maintain performance for decades with minimal maintenance. This reduces the need for frequent repairs or replacements.

Frequently Asked Questions

We focus on providing attic roof insulation solutions that improve energy efficiency and comfort. Our services include assessment, installation, and recommendations tailored to each home’s needs.

  • Why is my house so hot/cold despite running AC/heat constantly?

    Poor or insufficient attic insulation is likely the culprit. Without adequate insulation, your conditioned air escapes through the roof while outside temperatures penetrate your home. In Glendale's hot summers, heat radiates down from your roof, forcing your AC to work overtime. During cooler months, warm air rises and escapes through an under-insulated attic. This creates an endless cycle where your HVAC system runs constantly but never maintains comfortable temperatures, resulting in sky-high energy bills.

  • What does attic insulation installation cost in Glendale?

    Attic insulation installation in Glendale typically ranges from $2,500 to $4,500 for an average home, depending on your home's size, current insulation condition, and material choice. Blown-in insulation generally costs less than batt installation, while premium materials like spray foam cost more upfront but offer superior performance. Most homeowners see the investment pay for itself within 2-3 years through reduced energy bills. We provide free estimates to give you an exact quote based on your specific needs.

  • What type of attic insulation is best for Southern California climate?

    Blown-in cellulose or fiberglass insulation performs exceptionally well in Southern California's dry, hot climate. These materials resist settling, provide excellent thermal resistance, and handle temperature fluctuations effectively. Radiant barrier insulation is also highly beneficial in Glendale, as it reflects heat away from your home during intense summer months. 

  • How thick should attic insulation be in Glendale?

    Glendale homes should have attic insulation measuring 13-18 inches thick to achieve the recommended R-38 to R-49 rating for Southern California. Most older homes have insufficient insulation, often only 6-8 inches, which explains poor energy efficiency. The exact thickness depends on your insulation type, with blown-in materials typically requiring more depth than batt insulation to achieve the same R-value. 

  • How long does attic insulation installation take?

    Professional attic insulation installation typically takes 4-8 hours for most Glendale homes. Smaller homes or simple additions may be completed in 3-4 hours, while larger homes with complex layouts or extensive prep work can take a full day. The timeline depends on factors like attic accessibility, whether old insulation needs removal, and the installation method chosen.
