Can Your New Roof Help Lower Your Energy Bills?

Florida Heat Starts at the Top: Can Your New Roof Help Lower Your Energy Bills?

Florida summers bring intense sun, high humidity, and months of extreme heat to the First Coast. Homeowners in Jacksonville, St. Augustine, Ponte Vedra Beach, Orange Park, and surrounding communities know how hard air-conditioning systems work to keep homes comfortable—and how quickly energy bills can climb as temperatures rise.

At Heritage Roofing of North Florida, we help homeowners throughout Northeast Florida explore innovative roofing options designed for our climate. Whether you live in Mandarin, Riverside, San Marco, Nocatee, Julington Creek, Fleming Island, Jacksonville Beach, Neptune Beach, Atlantic Beach, or anywhere along the First Coast, a roof replacement is an opportunity to think beyond the shingles and consider how your entire roofing system can work smarter for your home.

One innovative option Heritage offers is ThermaSheet®, an insulated roofing underlayment designed to help reduce heat transfer through the roof assembly. Installed as part of your new roofing system, ThermaSheet adds another layer of performance between Florida’s intense heat and your home.

Why Florida Heat Matters for Your Roof

Your roof takes the first hit from Florida’s intense summer sun. As the roofing system heats up, that heat can transfer through the roof assembly and contribute to higher temperatures below.

This can cause your air-conditioning system to work harder to maintain a comfortable indoor temperature, especially during North Florida’s hottest months.

Factors that can affect heat transfer and home comfort include:

  • Roofing materials
  • Roof color
  • Attic insulation
  • Roof ventilation
  • Underlayment
  • HVAC efficiency
  • Overall home construction

Choosing the right roofing system during a roof replacement can help homeowners address more than protection from rain and storms.

What Is ThermaSheet®?

ThermaSheet® is an insulated roofing underlayment that can be installed as part of a new roofing system. It is designed to help reduce heat transfer through the roof assembly and improve the overall thermal performance of the system.

Potential benefits include:

  • Helping reduce heat transfer through the roof assembly
  • Supporting a more energy-efficient home
  • Helping reduce demand on your cooling system
  • Adding another performance layer beneath your roof
  • Potentially helping lower energy costs

Actual energy savings will vary depending on the home, roof assembly, insulation, HVAC system, energy usage, and other factors.

Could ThermaSheet® Help Lower Your Energy Bills?

By helping reduce heat transfer through the roof assembly, ThermaSheet® may help reduce the amount of work required from your home’s cooling system.

For some homes, improved energy efficiency may help reduce energy costs by up to 20%. Actual results will vary based on the home and installation conditions.

For Florida homeowners facing long cooling seasons and rising summer temperatures, energy efficiency can be an important consideration when choosing a new roofing system.

Why Consider ThermaSheet® During a Roof Replacement?

A roof replacement is one of the best opportunities to evaluate the components beneath your shingles.

Once your existing roofing materials are removed, the roof deck is accessible and your new roofing system can be built from the deck up.

The process includes:

1. Prepare the Roof Deck

The existing roofing system is removed and the roof deck is inspected.

2. Install ThermaSheet®

ThermaSheet® is installed as part of the roofing system according to the selected roof assembly.

3. Install Your New Roof

Your new roofing materials are installed over the properly prepared roofing system.

4. Enjoy the Benefits

Your new roof provides protection, curb appeal, and an additional focus on energy performance.

More Than Shingles: A Complete Roofing System

A roof is more than the material you see from the street.

A complete roofing system may include:

  • Roof decking
  • Underlayment
  • Ice and water protection
  • Flashing
  • Ventilation
  • Starter shingles
  • Field shingles
  • Hip and ridge shingles
  • Energy-efficient upgrades

At Heritage Roofing of North Florida, we help homeowners understand their options and choose a roofing system based on their home, performance needs, and budget.

For some homeowners, that may include premium shingles. For others, it may include upgraded ventilation, enhanced underlayment, or an innovative option like ThermaSheet®.
