Maximizing Efficiency with Energy-Smart Commercial Roofing
Most energy costs in a commercial property come from heating and cooling. No customer or employee wants to feel uncomfortable because of poor temperature control inside your business. To prevent this issue, you must balance cost with comfort, while also staying compliant with workplace temperature standards for your commercial building.

What Does “Green” Roofing Mean?
Traditional roofing systems using black tar, asphalt, or gravel often absorb heat, raising indoor temperatures and forcing air conditioners to run continuously. A new trend, however, is changing that: “green” or energy-efficient roofing. This approach promotes environmental stewardship while improving comfort, lowering energy costs, and reducing the Urban Heat Island Effect that traps heat in city environments.
At Harold Hall Commercial Roofing, we install energy-efficient roofing systems designed to reduce utility costs and increase comfort — helping your business save money year after year.
Below is an overview of key energy-efficient roofing concepts to help you understand how a “green” or “cool” roofing system works.

Why Choose Energy-Efficient Roofing?
Businesses everywhere are looking for ways to improve their buildings while reducing energy costs. A proven solution is the cool roof system, which uses reflective underlayments such as Low-E Therma-Sheet installed beneath new or existing tile, metal, or asphalt roofs. This material features a closed-cell polyethylene foam core laminated with 98% brushed aluminum that reflects, rather than absorbs, sunlight. It provides exceptional insulation, reducing attic temperatures by up to 30 degrees and significantly lowering cooling and heating costs.

Expert Insights on Cool Roof Efficiency
Conventional roofs can reach temperatures of 150°F or more on a sunny summer afternoon, while a properly designed reflective roof can stay more than 50°F cooler.
Buildings with cool roofs use less air-conditioning energy, stay more comfortable during hot weather, and can help reduce urban heat islands.

Prefer something other than white? Tan, cream, and light gray are also effective reflective options. Just remember: lighter is cooler, darker is hotter.
Harold Hall Roofing offers a wide variety of attractive, durable roofing systems that can reduce your energy bills by up to 15%. We also provide affordable financing options so you can enjoy the benefits of energy-efficient roofing on nearly any budget.
Why Choose a Cool Roof?
Bright or white roofs are 50–60 degrees cooler than dark roofs. They reduce the cooling load on your building, lowering energy costs and making your space more comfortable. By minimizing UV radiation gain and heat retention, cool roofs help create a more pleasant environment for customers and employees alike.

Dependable Cool Roof Services
Cool roof systems deliver a wide range of benefits, from lower maintenance and energy savings to longer lifespan. Because they resist UV damage, cool roofs last longer and reduce wear on HVAC systems. They also help lower carbon emissions and promote a more sustainable business environment.
Proper ventilation is another key to roof efficiency. Your roof’s attic or cavity should bring in cooler outside air and exhaust hot, humid air. We often recommend solar-powered ventilation fans that work automatically using free solar energy — no wiring or electricity required.
Green Roofs
For flat or low-slope commercial buildings, green roofs are a modern, energy-smart solution. They involve a layer of vegetation that provides natural insulation, improves stormwater management, and enhances aesthetics. While green roofs can have higher upfront costs, they deliver long-term value through lower energy bills, improved air quality, and reduced heat retention.
Green roofs are also known as living roofs or rooftop gardens. They lower surrounding air temperatures, ease cooling loads, and create visually pleasing rooftop spaces. Additionally, they absorb rainwater and extend roof longevity — all while turning unused roof space into a functional, eco-friendly feature.
Harold Hall Roofing helps businesses evaluate the best energy-efficient roofing system for their climate and structure. Our experienced team ensures your roof is designed for optimal performance, long life, and measurable energy savings.
Additional Services
In addition to cool and green roofing systems, we provide:
Skylight & Sun Tunnel Installation
Brighten your workspace with natural sunlight by installing an energy-efficient skylight or sun tunnel. Our team integrates these systems seamlessly into your existing roof structure, enhancing aesthetics while reducing reliance on artificial lighting.
Venting Installation Services
Proper attic ventilation reduces moisture, heat, and humidity — extending roof life and preventing damage. A well-ventilated roof minimizes temperature differences between indoor and outdoor air, protecting structural components and lowering energy use.
Chimney Repair
A watertight chimney is essential to maintaining your roof system. Cracked mortar joints, loose crowns, or deteriorated flashing can lead to leaks and damage. Our experts inspect and repair chimneys to keep your structure safe and dry.

FAQs
Should we add insulation to save energy?
Yes. Insulation plays a crucial role in conserving energy. It prevents heat transfer through your roof, maintaining stable indoor temperatures and improving overall comfort.
Why specify a cool roof?
Cool roofs are ideal for a variety of climates and industries. Harold Hall Roofing performs detailed inspections to recommend materials that deliver the right temperature balance and energy efficiency for your building.
What is the most energy-efficient material?
Efficiency depends on your climate. In hotter regions, reflective materials like white PVC membranes, reflective tiles, or specialized coatings perform best. In cooler regions, we balance reflectivity with insulation to maintain comfort year-round.
Will I save money even if my building is already well-insulated?
Yes. Reflective roofing enhances insulation performance and extends roof life, delivering substantial long-term savings on maintenance and energy bills.
