Don't Believe These Three Misconceptions About Foam Roofing
Spray foam roofs have been used on commercial buildings for decades, and they are increasing in popularity for residential homes. Although they are eco-friendly, energy-saving, and long-lasting, many people overlook spray foam roofs as an option for their homes because they believe one of these common misconceptions. Only when you know the real truth are you able to accurately decide whether or not a foam roof is right for you.
Misconception 1: It's hard to care for a spray foam roof because you can't walk on it.
When you picture a spray foam roof, are you picturing a porous, foam structure similar to a mattress? Many people have this mental image of a squishy, unstable roof that cannot be walked on. However, spray foam roofs are actually very hard and sturdy enough to be walked upon. After the foam is applied, the roof is coated in a layer of solid coating, which can be safely walked across when you need to make repairs, mend gutters, or brush off debris.
Misconception 2: Spray foam roofs don't save enough energy to be worth it.
Actually, for most building owners, spray foam roofs lead to energy savings compared to costs with a traditional asphalt roof. When coated in white, reflective substances, spray foam not only saves energy by providing better insulation, but also by reflecting away the hot sunlight rather than absorbing it. This may lower the roof temperature by up to 100 degrees and reduce energy bills by up to 50%.
Misconception 3: Water can pool on spray foam roofs and cause structural problems.
Once again, it's important to remember that cured spray foam is not like the foams you're used to seeing in mattresses and pillows. It is a dense, waterproof foam that will not absorb liquid. In fact, its propensity for deflecting moisture is one of the things that makes it such a good roofing substance. It does not become water-logged and promote rot like some wood-based roofing frames might if asphalt shingles start to fail.
Now, there is some concern regarding pools of water forming if the spray foam is not applied at the correct slope. Water accumulation in "pools" on the roof may cause damage by increasing the roof load. However, this issue can be avoided by working only with experienced roofers who have a good track record. They should be able to properly configure the slope of the spray foam roof so that pooling does not occur.
Spray foam roofs are waterproof, sturdy, and energy-efficient. Now that you know the truth, you can have more confidence in your decision whether or not to have this innovative type of roof installed on your home. When it comes to foam roofing, residential roofers can help you explore your options.
