What Are The Most Energy-Efficient Flat Roof Coatings?

If you've been considering reroofing your commercial building to save on heating and cooling costs, you're not alone. For many properties, the roof can be one of the biggest sources of energy inefficiency—light-absorbing roofs may make it hard to keep your building cool in the summer, while ultra-reflective roofs can make a cold climate seem even colder. In many cases, simply resealing your current roof with a flat roof coating can provide you with the cost savings you're seeking. Read on to learn more about some of the factors you'll want to consider when deciding on an energy-efficient coating, as well as some of the options available to you.

What Should You Consider When Deciding on a Roof Coating?

There's no one-size-fits-all option when it comes to the best roof coating for your needs. Some of the factors you'll want to keep in mind while browsing your options include the following.

Your roof's exposure to sunlight at all four times of year. For example, if you have very little sun exposure during the summer, when trees are leafed, but maximum sun exposure during winter, you may want a light-absorbing roof that will keep your building warm in the winter and won't receive much sunlight during the warmer months.

The amount of heat generated by your business's operations. If you run a manufacturing facility that is hard to keep cool, even in the winter, you'll want a roof that reflects as much light as possible to assist with climate control.

Your roof's exposure to potential sources of debris like trees, as well as its likely exposure to pollution like soot and smoke. If you're in a heavily-trafficked or industrial area, the residue from car exhaust and factory emissions may settle on your roof, forming a sticky and potentially toxic coating. By choosing a roof material that's treated to repel this pollution, you can reduce the amount of cleaning and maintenance you'll need to do.

What Are Your Roof Coating Options?

There are several types of commercial flat roof coatings available. Some, like synthetic rubber, provide a water-repellent seal that's ideal for properties that need a bit of extra insulation. These roofs are also long-lasting, which means you can take a "set it and forget it" approach.

Another type of roof is often called "liquid granite," and mixes a polymer with crushed rock to create a concrete-like coating. These roofs are especially impervious to pollution, and can be good for industrial areas. 

Finally, you can opt for PVC roof coating. Like the material that makes PVC pipes, this plastic is lightweight and can be treated to reflect heat away from your building.
