If your energy bills seem higher than they should be, your roof might be part of the problem. In many homes across Union and surrounding Missouri communities, outdated roofing systems allow heat to escape in the winter and increase heat buildup in the summer. Investing in a new roof isn’t just about aesthetics or storm protection—it’s a smart way to improve your home’s energy performance. In this article, Emmendorfer Exteriors explains how new roofing enhances roofing energy efficiency, what materials work best in Missouri’s climate, and why now might be the perfect time for an upgrade.
Why Roofing Energy Efficiency Matters
Energy efficiency refers to how well your home maintains its internal temperature without over-relying on heating and cooling systems. While windows, insulation, and HVAC systems play major roles, your roof covers a large surface area and is constantly exposed to the elements. That means it significantly impacts how much heat your home absorbs or loses.
Poor ventilation, damaged shingles, and outdated materials can cause your roof to trap heat in the summer or let it escape in the winter. Improving your roofing energy efficiency can reduce your utility bills, extend the life of your HVAC system, and create a more comfortable indoor environment year-round.
How an Old Roof Can Drain Energy
Older roofing systems often lack the modern features needed to resist heat transfer. In homes across Union, Washington, and Eureka, we’ve seen roofs that are 20 to 30 years old and still made of materials that do little to block UV rays or regulate airflow. This leads to several problems:
- Heat buildup in attics during summer
- Cold drafts and ice damming in winter
- Poor ventilation and trapped moisture
- HVAC systems working overtime to maintain a comfortable temperature
If your home feels like an oven in July and an icebox in January, your roofing energy efficiency may be falling short.
What Makes a Roof Energy-Efficient?
Several elements contribute to roofing energy efficiency, including materials, color, installation methods, ventilation, and insulation. Let’s break them down:
1. Reflective Roofing Materials
Modern roofing options like metal, architectural shingles, and cool roof coatings are designed to reflect more sunlight and absorb less heat. Reflective surfaces reduce the amount of heat that enters your attic, which in turn reduces the load on your air conditioning system.
2. Proper Ventilation
Ventilation is critical to maintaining roofing energy efficiency. Ridge vents, soffit vents, and attic fans help regulate temperature and humidity levels in your attic space. Without proper airflow, heat and moisture become trapped, degrading insulation and roofing materials over time.
3. Insulated Roof Decking
Some new roofing systems include insulated panels that provide an extra barrier against heat transfer. While this option isn’t necessary for every home, it can significantly boost energy performance in homes with little attic insulation.
4. Light-Colored Shingles or Metal Panels
Lighter colors naturally reflect more sunlight, while dark roofing materials tend to absorb heat. If your current roof is dark and exposed to direct sunlight most of the day, switching to a lighter roofing material can instantly improve roofing energy efficiency.
5. Quality Installation
Even the most energy-efficient roofing material won’t perform well if it’s installed incorrectly. At Emmendorfer Exteriors, we ensure every roof is properly sealed, ventilated, and protected from moisture intrusion—key elements that affect long-term performance.
The Best Roofing Materials for Missouri Homes
Missouri weather brings hot, humid summers and cold, snowy winters. That means homeowners in areas like Festus, St. Clair, and Pevely need materials that can adapt to seasonal changes and maintain roofing energy efficiency throughout the year.
Asphalt Shingles (Architectural-Grade)
These remain a popular choice due to affordability and availability in energy-rated versions. Look for shingles with ENERGY STAR® ratings that include reflective granules designed to minimize heat absorption.
Metal Roofing
Metal roofs are highly reflective and incredibly durable. They reflect solar heat better than asphalt and often come with coatings that enhance energy performance. Metal is one of the top choices for homeowners concerned with long-term roofing energy efficiency.
Synthetic or Composite Roofing
Made to mimic slate or wood, these materials offer strong durability and UV resistance. Many are engineered for thermal regulation and offer better insulation than traditional wood shakes or older shingle types.
Cool Roof Systems
These specialized roofs are designed specifically for energy savings. They combine reflective coatings with high-performing materials to offer maximum heat resistance.
How Much Can You Save?
Improving your roofing energy efficiency can lead to serious cost savings over time. According to the U.S. Department of Energy, energy-efficient roofing can reduce cooling costs by 10–15%. In a climate like Missouri’s, where both heating and cooling costs fluctuate seasonally, this can translate to hundreds of dollars saved annually.
Additionally, a more energy-efficient roof can reduce wear and tear on your HVAC system, resulting in fewer repairs and a longer system life span.
Signs Your Roof Is Hurting Your Energy Efficiency
Not sure if your current roof is costing you more than it should? Watch for these warning signs:
- High utility bills despite moderate HVAC use
- Uneven temperatures between floors
- Hot or cold attic spaces
- Ice dams forming during winter
- Curling or blistering shingles
- Stains on ceiling or walls indicating poor insulation
If you’ve noticed any of these, it might be time to explore your roofing energy efficiency options with a trusted local contractor.

Additional Tips to Maximize Roofing Energy Efficiency
Your roof plays a major role in your home’s overall energy performance, but a few extra upgrades can further boost results:
- Install radiant barriers in the attic to reflect heat
- Add insulation to attic floors and walls
- Seal air leaks around vents, ducts, and chimneys
- Use light-colored or reflective roofing materials where possible
- Keep gutters clear to prevent moisture-related damage
A roof replacement is the perfect time to make these improvements. When done together, they provide long-term comfort, savings, and protection.
