Quick Answer

Small roofing mistakes (like poor ventilation, insulation gaps, or low-reflective shingles) can cause Detroit homeowners to lose up to 25% more energy each season. Choosing high-performance materials from Tilcor, GAF, or Owens Corning, and hiring certified installers like Great Lakes Home Remodeling, prevents this waste and saves money long-term.

Why Roofing Affects Your Home’s Energy Efficiency

Your roof isn’t just a shield, it’s your home’s first defense against heat, cold, and moisture. In Detroit’s climate, where summers can be humid and winters brutally cold, a poorly designed or installed roof can cause major energy loss.

According to the U.S. Department of Energy, up to 40% of a home’s heat gain and loss happens through the roof and attic. That means ventilation, insulation, and materials all directly affect your comfort and utility bills.

5 Common Roofing Mistakes That Waste Energy

1. Poor Attic Ventilation

Without proper airflow, attics trap heat in summer and moisture in winter, both of which degrade insulation and increase HVAC load.
Manufacturers like Owens Corning recommend ridge and soffit vents to balance air exchange and reduce condensation that weakens energy efficiency.

2. Inadequate Insulation

If your attic insulation is too thin or poorly installed, heated air escapes in winter and hot air seeps in during summer. Owens Corning PINK® Fiberglas™ Insulation helps stabilize indoor temperatures and lower heating costs by reducing energy transfer through your roof deck.

3. Using Dark or Low-Reflective Roofing Materials

Dark asphalt shingles absorb heat instead of reflecting it, raising attic temperatures by up to 30°F.
Tilcor’s stone-coated metal roofs and GAF’s cool roof shingles use reflective pigments and light stone coatings to reduce solar absorption, helping Detroit homeowners cut air-conditioning costs during long, humid summers.

4. Neglecting Roof Leaks or Gaps

Even small leaks or loose flashing can compromise your insulation and airflow. Water intrusion leads to damp insulation, which loses up to half its effectiveness once wet. Regular inspections can identify and seal leaks before they drive up your energy costs.

5. Improper Installation and Airflow Design

Incorrectly installed underlayment, vents, or flashing can trap heat and moisture. Certified installers follow manufacturer guidelines, ensuring your roof “breathes” efficiently.
That’s why working with a licensed and insured contractor like Great Lakes Home Remodeling is essential for Detroit homeowners.
