Inefficient heating and cooling of commercial buildings result in high energy costs for businesses and negative environmental impacts. The good news is that there are many methods for saving energy bills, including using the right roofing materials and ensuring proper attic ventilation.

Energy-efficient roofs (cool roofs) reflect sunlight and heat rather than absorb them. These roofs are often made of light-colored materials with special reflective coatings, and they can greatly reduce the cost of air conditioning in warm weather.

Metal Roofs

Metal roofs are highly durable and can protect the interior of a commercial building from harsh weather conditions. This type of commercial roofing in Baton Rouge also offers a variety of sustainability benefits.

For example, they are extremely energy efficient because they reflect sunlight. This reduces the amount of heat that is absorbed into the attic, which in turn lowers utility bills. Furthermore, they can be painted with a high solar reflective index (SRI), such as white, to enhance their energy efficiency further.

Additionally, metal roofs can hold in heat in the winter and keep interior temperatures cooler in the summer, reducing energy consumption. They can also be augmented with insulation to maximize their energy-saving capabilities. Additionally, many states and localities offer tax incentives and rebates to encourage businesses to opt for a more energy-efficient roofing system.

In addition to boosting a building’s energy efficiency, metal roofs are fire-resistant. This makes them an excellent choice for areas prone to wildfires. Additionally, they are easy to maintain and can last twice as long as shingle roofs.

Finally, they can be augmented with additional insulation to minimize sound levels during heavy rain or hailstorms. This can greatly increase the comfort of a building’s occupants. Also, unlike shingles, they do not attract mildew and fungus. This means they do not require regular maintenance, saving businesses time and money.

Cool Roofs

People in tropical warm climates often wear light-colored clothing to keep cool; the same concept applies to roofs. Cool roofing systems are designed to reflect the sun’s rays rather than absorb them like conventional roof materials. This results in lower building temperatures and energy costs, allowing occupants to keep their air conditioning in more comfortably.

Cool roofs are a great solution for commercial buildings, especially those with flat or low-sloped structures. They offer the potential to significantly reduce energy consumption and expenses, increase the life of a roof, and cut maintenance costs. They can also help mitigate the “urban heat island” effect by decreasing urban air temperatures, reducing the production of ground-level ozone and other pollutants, and improving overall air quality.

The initial investment in a cool roof can be higher than traditional asphalt shingle roofs, but the long-term cost savings can be substantial. They can save on air conditioning costs, reduce electricity usage during peak demand times, and save on peak energy charges when using time-of-use meters.

Moreover, since cool roofs do not require the removal of existing material and can be applied directly to existing roofs, they are a much less disruptive option than complete roof tear-off and replacement projects. They also help reduce the amount of roofing waste sent to landfills, lowering environmental impacts.

Green Roofing

Green roofing is much more than what meets the eye. Most people are attracted to the outer vegetation but do not realize the detail beneath. There are two main types of green roofs: intensive and extensive.

A thick soil profile with fewer layers characterizes the intensive roof design. In contrast, the extensive roof has many deep soil layers and various plants. The soil profile of intensive roofs and the plants available are the main differences between them. Plants on intensive green roofs are more diverse, while those on extensive green roofs are fewer.

It is also easier to install and maintain extensive roofs than intensive ones. The homeowner can choose the option that works.

Green roofing refers to any roof covered with vegetation planted over a waterproofing membrane. Its benefits include:

  • Absorbing rainwater.
  • Improving insulation.
  • Creating a habitat for wildlife.
  • Reducing air temperatures in urban environments (which helps mitigate the “heat island effect”).

Aside from their environmental advantages, green roofs also improve energy efficiency by slowing heat transfer from the building to the environment. This helps reduce the amount of energy required for cooling. In addition, the vegetation on a green roof consumes carbon dioxide, which improves indoor air quality and increases occupant comfort.


Finally, the growth medium on a green roof extends the life of the waterproofing membrane underneath. The National Roofing Contractors Association states that green roofs provide an additional layer of protection from UV radiation and significantly reduce the wear of a roofing system, even on hot asphalt or modified bitumen membranes.

The insulative value of green roofs can make them suitable for use on various structures, including commercial buildings, apartment complexes, and retail spaces. In addition, their aesthetics can draw in tenants and boost a company’s reputation for environmentally friendly operations. They can even be a selling point for certain businesses, such as restaurants that want to attract customers who desire healthy food.
