The Business Benefits of Green Roofing Systems

Portland’s Central Library has a living roof.

As a way to conserve energy and slow climate change, many flat roofs are now becoming green roofs. Traditional black roofing materials absorb a tremendous amount of heat, especially when we get a lot of sunshine. This increases the need for air conditioning, which creates one of the most harmful emissions polluting the air today.

For the past 30 years or so, architects and roofing material manufacturers have been working to find and produce environmentally conscious (and affordable) solutions for flat roofs.

Cool Roofs

One of the most effective ways to improve a building’s energy efficiency is to install a roof membrane that will reflect sunlight (Solar Reflectivity) and release absorbed heat (Infrared Emittance). According to the U.S. Department of Energy (DOE), these two properties could cut a building’s annual energy costs by up to 20 cents per square foot on average, depending on the climate and the quality of the new roof .  Check out their Cool Roof Calculator.

When it comes to cool roofs, Pacific West Roofing works with FiberTite® materials. The Cool Roof Rating Council gave FiberTite® roofing membranes one of the highest ratings in the industry for both Solar Reflectivity and Infrared Emittance, and it’s also ENERGY STAR® compliant.

Living Roofs

Why not take it another step further, and cover your roof with plants that clean the air? People have had rooftop gardens for centuries, but just in the last few decades, they’ve become a popular design feature for eco-conscious commercial buildings and retrofits.

What can a living roof do for you?

  • Filter harmful pollutants and re-oxygenate the air.
  • Naturally reduce heat and help lower localized temperatures (Urban Heat Island Effect).
  • Insulate your building and cut energy costs.
  • Reduce the risk of flooding and wastewater overflow by retaining rainwater.
  • Slow water down so as not to overload the sewer and river systems.
  • Extend the life of your roofing membrane by reducing temperature fluctuations.
  • Provide a noise barrier, making a quieter work environment.
  • Give building occupants a private outdoor area for gardening and relaxation.

A vegetative roof requires a very special infrastructure. Without it, rot, mold, and disaster are inevitable. For a truly watertight roofing system, nothing beats a FiberTite membrane, with molecularly welded seams for unprecedented strength. They are designed to resist the damaging effects of chemicals, plant microbes, and rooting. And, with the combined technology of densely packed polyester fabric and a unique DuPont Elvaloy coating, FiberTite membranes are flexible yet unpuncturable.
