Signs You Need Attic Insulation or an Insulation Upgrade

High Energy Bills

If your energy bills are climbing, your attic insulation might be to blame. Poor or aging insulation can let valuable heat escape in the winter and allow unwanted heat during the summer, forcing your HVAC system to work harder.

Upgrading your attic insulation is one of the most cost-effective ways to reduce energy consumption and lower your monthly utility bills. With better insulation, your home holds in the air you pay to heat or cool, which means less energy is used and more money is saved every month.

Schedule an inspection to see if your attic insulation is up to standard.

Uneven Indoor Temperatures

Does one room feel like a sauna while another feels like a freezer? Attic insulation plays a key role in balancing your home’s overall temperature.

Inconsistent indoor temperatures are a major red flag that your insulation needs to be checked out, especially in the attic.

Ice Dams and Roof Leaks

In winter, heat escaping through your attic can melt snow on the roof, leading to ice dams. These block proper drainage and can cause roof damage or leaks.

If you’ve noticed ice dams on your roof, it’s time to inspect your attic insulation.

Pests and Moisture

Insufficient attic insulation can let moisture seep in and create an inviting environment for pests or mold growth.

Protect your home from moisture and pests — let us help you with insulation that safeguards your home.

The Benefits of Professional Attic Insulation Services

Improved Energy Efficiency

Proper attic insulation reduces energy loss and improves your home’s HVAC performance. That means your home stays reliably cooler in the summer and warmer in the winter, and you reap the benefits of lower heating and cooling costs all year.
