Energy-Efficient Roofs: Allaying Four Concerns About Polyurethane Foam

Beverley Hall

According to the U.S. Department of Energy, heating and cooling costs make up more than half of the total energy costs for the average home in the United States. So in order to keep your bills low, it's important to be able to heat and cool your home as efficiently as possible. The type of roof on a home can have a big impact on energy efficiency.

If you have a home with a no- or low-slope roof, then one of the most efficient types of roof you can get is a foam roof. Although it might sound funny – people think of foam as being soft, better for mattresses than construction work – foam roofs have been around for decades. There's a fair bit of misinformation out there about foam roofs, unfortunately, but hopefully the following facts will help clear things up.

Concern 1: Can Foam Really Be That Sturdy?

Foam roofs, with proper maintenance, will last for many decades. After all, polyurethane is used for such high-wear products as shoe soles and ship hulls. In fact, since so many older foam roofs are still in good condition today, it's difficult to say just how many decades they are capable of lasting!

Concern 2: Aren't The Materials Toxic?

Polyurethane foam is a form of plastic. While you certainly wouldn't want to eat it, it's no more toxic than sleeping on a foam mattress. However, it is important to have any polyurethane foam installed correctly. Mistakes during installation can lead to the materials in the foam not mixing properly, which means leftover chemicals. This means proper and professional installation of polyurethane foam is key.

Concern 3: Won't Foam Soak Up Water?

Some people think of foam as being like a sponge, full of open holes. But the foam in a foam roof is something called "closed cell" foam. This means that the millions of little cells of air within the foam, which give it such excellent insulating properties, are completely sealed off from each other; no water can penetrate them.

Concern 4: Can't You Just Use Foam Boards?

The difference between a foam board roof and a true spray foam roof is in the seams. A spray foam roof is made on-site, conforming to the size of roof you need with no joining pieces or seams. Foam boards, on the other hand, need to be pieced together. So while they are both made of good insulating materials, those seams lower the overall insulating ability of the roof – and are also areas for potential leaks, while spray polyurethane foam is waterproof.

This information can help you understand why foam roofing is a good a option. For more information about roofing options, contact local contractors at a company like Dodge Foam & Coatings Inc.

Learning All About Roofing Materials

Hi, I'm Dwight Eberstark. I am crazy about all of the different types of roofing materials available today. While upgrading the roof on my home, I looked into the material options in great detail. I studied all of the different metal materials used to create modern shingles. I also looked into switching to asphalt, wood or tile shingles. I eventually settled on bronze shingles designed to last for decades. Instead of aging, the bronze finish just continues to improve. I also switched to metal gutters that make a beautiful sound when the rain falls onto the surface. I would like to share my passion for roofing materials through this site. Thank you for coming by.
