Is A Cool Roof Coating The Answer To Your Business's Energy Needs?
If you find yourself constantly struggling to keep your commercial or manufacturing building cool during the summer months, you may be wondering whether there are any structural changes you can make to reduce your energy consumption and cut costs during the hottest times of year. With more and more companies seeking alternative ways to reduce their reliance on air conditioning systems, the "cool roof" has made a comeback. Today, many businesses rely on tried-and-true heat reduction methods to cool their buildings from the outside in. Read on to learn more about cool roofs and how this group of innovative roofing materials may be able to cut your business's energy costs for good.
How Can A Cool Roof Help Your Business Conserve Energy?
The term "cool roof" can refer to a wide variety of materials and construction styles, but generally refers to a roof that has been designed to reflect sunlight and repel heat. This can be accomplished through the use of reflective paint, a heat-reducing shield, or reflective tiles, shingles, or metal panels that prevent the sun's rays from penetrating.
By reflecting sunlight, this roof can significantly reduce the heat flow from the outside to the inside of your building, allowing your air conditioners to run more efficiently and reducing wear and tear on your other HVAC components. Even if you generate heat from the inside of your building, through manufacturing processes or just the gathering of many warm bodies, it is much easier to ventilate this heat to the outdoors when you're not also absorbing added heat from the sunshine. And buildings with a large "footprint" may even be able to reduce the ambient temperature around the building by installing a cool roof.
What Type Of Cool Roof Is Right For Your Business?
The ideal cool roof for your building can depend largely upon the functions this building performs, its location, the amount of sunlight to which it's exposed, and even the number of windows. Fortunately, there are many ways to make an existing roof cool, ensuring you won't need to replace your roof unless it's already nearing the end of its lifespan.
If your current roof is metal, one of the easiest ways to make it cool is to paint on a reflective cool roof coating. This is a type of ultra-thick paint that contains UV filters, preventing the sun's rays from penetrating through the paint to the metal below. These UV filtering molecules also prevent the paint from fading or losing effectiveness for decades after installation. Some roof coating paints are designed to be waterproof as well, helping protect your roofing tiles against rust and other byproducts of years of water exposure.
Flat Rubber Roofs
If your business's roof is flat, it may be a perfect candidate for a layer or two of spray polyurethane. This rubbery coating is made by mixing two liquid chemicals; the resulting expansion creates a single solid layer that adheres to the roof and protects it from heat penetration. Spray polyurethane roofs are also water-resistant, perfect for flat roofs that often have unique drainage needs.
Asphalt Roofing Tiles
For homes with asphalt tiles, applying an outer layer of chipped marble or another more reflective substance to each tile can add some reflective dimension to your existing roof. There are also some rubber-based "cool coatings" that can be sprayed onto your roofing tiles to transform them from hot to cool.
Regardless of what you're currently working with, it's likely you'll be able to create a cool roof without replacing your existing roofing tiles or panels. By doing so, you'll not only improve your roof's performance, but extend the life of your HVAC system and reduce your business's overhead expenses for years to come.
