How a New Roof Can Lower Your Energy Bills in Oklahoma

Oklahoma summers are no joke. When the temperature hits 100°F and stays there for weeks, your air conditioning system works overtime — and your energy bills reflect it. What many homeowners don't realize is that their roof plays a massive role in how much energy their home uses. An old, poorly ventilated, or dark-colored roof can add hundreds of dollars to your annual cooling costs. Here's how a new roof can change that.

Your Roof Is Your Home's First Line of Defense Against Heat

On a 100°F Oklahoma summer day, the surface temperature of a dark asphalt shingle roof can reach 150°F to 170°F. That heat radiates down through the decking and into your attic, which can easily hit 140°F or more. From there, it seeps through your ceiling insulation and into your living space, forcing your AC to work harder and longer to maintain a comfortable temperature.

A properly designed roofing system addresses this heat transfer at multiple points: the shingle surface, the ventilation system, and the insulation layer.

Cool Roof Shingles

Modern "cool roof" shingles are engineered with solar-reflective granules that reflect more of the sun's energy instead of absorbing it. While a standard dark shingle might reflect only 5-15% of solar energy, cool roof shingles can reflect 25-40%. That difference translates directly into a cooler attic and lower cooling costs.

Several manufacturers we work with — including Malarkey and CertainTeed — offer Energy Star-rated shingles that qualify as cool roofing products. These shingles come in a range of colors, so you don't have to sacrifice curb appeal for energy efficiency. Even medium-toned shingles with reflective granules can significantly outperform older dark shingles.

Proper Attic Ventilation

Ventilation is arguably the most underappreciated factor in roof energy efficiency. A properly ventilated attic allows hot air to escape through ridge vents or exhaust vents at the top while drawing cooler air in through soffit vents at the bottom. This continuous airflow prevents heat from building up and radiating into your living space.

When we replace a roof at ScottBuilt, we always assess the existing ventilation system. Many older Oklahoma homes have inadequate ventilation — either not enough intake vents, not enough exhaust vents, or both. Adding proper ventilation during a roof replacement is one of the most cost-effective energy upgrades you can make.

Radiant Barriers and Insulation

For homeowners who want maximum energy savings, we can install a radiant barrier on the underside of the roof decking during replacement. A radiant barrier is a reflective material that blocks up to 97% of radiant heat transfer from the roof into the attic. Combined with proper insulation (R-38 to R-60 is recommended for Oklahoma), a radiant barrier can reduce attic temperatures by 20-30°F.

Metal Roofing: The Energy Efficiency Champion

If maximum energy efficiency is your goal, metal roofing is hard to beat. Metal roofs reflect significantly more solar radiation than asphalt shingles, and they re-emit absorbed heat much faster once the sun goes down. Studies have shown that metal roofs can reduce cooling costs by 10-25% compared to dark asphalt shingles.

Metal roofs also last 40-60+ years, which means you'll enjoy those energy savings for decades. The higher upfront cost is offset by lower energy bills, minimal maintenance, and the fact that you'll likely never need another roof replacement.

Real Savings for Oklahoma Homeowners

How much can you actually save? Here are some realistic estimates for a typical Oklahoma City home:

• Upgrading from old dark shingles to cool roof shingles: 7-15% reduction in cooling costs
• Adding proper attic ventilation: 5-10% additional reduction
• Installing a radiant barrier: 5-10% additional reduction
• Switching to a metal roof: 10-25% total reduction in cooling costs

For a homeowner spending $250/month on electricity during peak summer months, even a 15% reduction saves $37.50/month — or $150-$225 over a typical Oklahoma cooling season (May through September).

Tax Credits and Incentives

Energy-efficient roofing materials may qualify for federal tax credits under the Inflation Reduction Act. Metal roofs and asphalt roofs that meet Energy Star requirements can qualify for a tax credit of up to 30% of the cost, up to $150 for the roofing material itself. While this won't cover the full cost, every bit helps — and it's worth discussing with your tax advisor.
