High Energy Bills
Unexplained increases in heating or cooling costs may indicate roof problems. Poor insulation, inadequate ventilation, or air leaks through the roof can significantly impact energy efficiency.
While not immediately critical, this should be addressed within a few weeks.
How to Identify This Problem
Look for these warning signs:
- Sudden unexplained increase in electric bills
- HVAC running constantly to maintain temperature
- Hot or cold spots in certain rooms
- Upper floors significantly warmer in summer
- Uneven temperatures throughout the home
- Ice dams forming in winter (in colder periods)
- Attic feels extremely hot in summer
Common Causes
Inadequate Attic Insulation
Thin or compressed insulation allows heat transfer between the attic and living space, increasing HVAC load.
Poor Roof Ventilation
Without proper airflow, attic temperatures can exceed 150°F in summer, radiating heat into living spaces below.
Air Leaks
Gaps around vents, chimneys, and penetrations allow conditioned air to escape and outside air to enter.
Dark Roofing Materials
Dark shingles absorb more solar heat than light colors, increasing cooling costs in hot climates.
Damaged or Missing Shingles
Gaps in roofing allow heat transfer and can indicate underlying damage affecting insulation.
Aging Roof System
Older roofs may have degraded underlayment and insulation that no longer performs efficiently.
Solutions & Repairs
Attic Insulation Upgrade
Professional RequiredAdding or replacing attic insulation to meet current R-value recommendations (R-38 to R-60 for most climates) dramatically improves efficiency.
Ventilation Improvement
Professional RequiredInstalling ridge vents, soffit vents, or powered ventilators creates proper airflow to reduce attic temperatures.
Air Sealing
DIY PossibleSealing gaps around penetrations, ductwork, and access points prevents conditioned air loss.
Cool Roof Installation
Professional RequiredLight-colored or reflective roofing materials can reduce cooling costs by 10-25% in hot climates.
Energy Audit
Professional RequiredA professional energy audit uses thermal imaging and blower door tests to identify specific efficiency problems.
When to Call a Professional
Contact WeatherShield Roofing immediately if you notice:
- Energy bills have increased 20%+ without explanation
- Your attic is extremely hot even with ventilation
- You notice the attic has less than 10 inches of insulation
- Air seems to flow from recessed lights or attic access
- Your roof is over 15 years old
- You want a comprehensive assessment of roof efficiency
Prevention Tips
- Ensure attic has adequate insulation (R-38 minimum in SC)
- Verify soffit vents are not blocked by insulation
- Install a radiant barrier in the attic
- Choose light-colored or cool roof shingles during replacement
- Seal air leaks around attic access and penetrations
- Schedule regular roof and HVAC maintenance
Frequently Asked Questions
What is a cool roof?
A cool roof is designed to reflect more sunlight and absorb less heat than a standard roof. This can be achieved through light-colored shingles, reflective coatings, or specialized materials. In hot climates like Myrtle Beach, cool roofs can significantly reduce cooling costs and improve comfort.
How do I know if my attic has enough insulation?
Check your attic - if you can see the ceiling joists, you likely need more insulation. For Myrtle Beach, the Department of Energy recommends R-38 to R-60 (about 10-15 inches of fiberglass). If insulation is compressed, wet, or unevenly distributed, it may not be performing effectively.
Will fixing my roof really lower my energy bills?
Yes, addressing roof-related efficiency issues can meaningfully reduce energy costs. The impact depends on current conditions and solutions implemented. Proper insulation, ventilation, and cool roofing can each contribute savings of 10-15%, with combined improvements sometimes exceeding 25%.
