Quick Answer

Energy efficiency starts at the top. In Mansfield, Ohio, roofing mistakes such as poor ventilation, weak insulation, and improper material installation can increase heating and cooling costs by up to 30%. Using systems from Owens Corning and GAF, designed for proper airflow and insulation, helps homeowners maintain consistent indoor temperatures year-round.

Why Energy Efficiency Matters for Mansfield Homes

Homes in Mansfield experience freezing winters and humid summers, both of which test your roof’s ability to regulate heat. According to the Ohio Department of Development’s Office of Energy, energy loss through the roof and attic is one of the most common causes of high utility bills in northern Ohio homes. Proper roofing and attic systems help reduce energy waste, lower emissions, and keep homes more comfortable.

4 Common Roofing Mistakes That Reduce Energy Efficiency

1. Poor Attic Ventilation

Inadequate ventilation traps heat and moisture, leading to premature roof aging and higher cooling costs. Both Owens Corning and GAF stress the importance of balanced intake and exhaust ventilation. Without airflow, attics can reach over 150°F in summer—forcing your HVAC system to work overtime.

2. Using Low-Quality or Mismatched Materials

Mixing incompatible roofing components—like generic underlayments or poorly sealed shingles—creates energy gaps. Certified systems from GAF and Owens Corning are engineered to work together, forming complete energy-efficient roofing systems that maximize insulation and reduce heat transfer.

3. Ignoring Insulation and Air Leaks

According to the Ohio EPA Energy Efficiency Program, homes without proper attic insulation can lose up to 25% of heating energy through the roof. Owens Corning’s AttiCat® insulation system helps close these gaps, while GAF’s EnergyGuard™ underlayments reduce thermal bridging that drives up energy costs.

4. Skipping Regular Roof Maintenance

Even the best materials fail without maintenance. Loose flashing, missing shingles, and debris buildup reduce reflectivity and airflow, leading to energy inefficiency. The Ohio Department of Commerce recommends annual roof inspections to catch these problems before they escalate.

How Owens Corning and GAF Roofing Systems Improve Efficiency

Both Owens Corning and GAF design complete roofing systems that enhance home energy efficiency. Owens Corning Duration® Cool shingles use reflective granules to reduce heat absorption, while GAF Timberline® Cool Seriesreflects sunlight to maintain cooler attic temperatures. When combined with attic insulation and ridge vents, these systems can cut annual energy costs by hundreds of dollars and extend the life of your roof.
