Spray Polyurethane Foam (SPF) roofing, or spray foam roofing, is a solution that can withstand the harshest climate and last for decades. Because it’s also eco-friendly, many commercial structures and even residential buildings are making the shift towards SPF roofing systems. Although the technology has been available for at least 40 years—since the 1960s— it’s recently gaining track because of the recent shift towards more sustainable choices.
If you are wondering whether or not you should make the switch to SPF roofing, read on to know more about this durable and cost-effective roofing solution!
What is Spray Polyurethane Foam?
Spray Polyurethane Foam is a material sprayed as a liquid to a surface, such as a roof. Once sprayed, it expands into a foam, creating a hard layer on top. An interesting fact is that SPF can expand up to 30 times its original liquid volume! SPF roofing uses specialized spraying equipment that makes sure the foam fills every crack and crevice of the roof surface to make it seamless and waterproof. This makes it one of the most reliable and durable roofing systems.
Though SPF is waterproof, it is not UV proof. The sun can cause damage to the material quickly. To mitigate this, a top coating, usually made of silicone materials, is applied. With this, the roof can endure the toughest environmental challenges, such as high winds, rain, snow, hail, corrosion, and even the eventual wear-and-tear.
How Long Will Spray Polyurethane Roofing Last?
When properly installed and regularly maintained, SPF roofing will last for over 50 years. Cleaning and re-coating every 10 to 15 years is important. It is also advisable that SPF roofing systems are inspected at least once a year or after extreme weather, such as intense storms. If repairs are needed, there is no need to tear off the existing roof, as a simple re-coating or re-spraying will be able to do the job.
Is SPF Roofing Environmentally Friendly?
SPF roofing is energy efficient because it provides effective thermal, air, and moisture barriers for better insulation of a building. In the summer, the polyurethane foam reflects the sun’s rays to cool the building. During winter, on the other hand, it traps the heat in to keep the building warmer. This way, building owners can save up to 50% on heating and cooling.
Because there is no need for tearing and stripping during installation and repairs, SPF roofs do not contribute to Earth’s waste problem as well. The materials used in Spray Polyurethane Foams are also certified to be environmentally friendly. It promises 100% green application, meaning there’s no off-gassing that can be harmful to humans and animals.
Is SPF Roofing Expensive?
The initial investment for a Spray Foam roof may cost more than other roofing systems. However, when you factor in its long lifespan and the savings you’ll get from energy, labor, and maintenance costs, you’ll realize that it is actually the more affordable option when compared to other roofing systems.
Durable, environmentally friendly, and economically efficient are some of the benefits of Spray Polyurethane Foam roofing systems. It’s no wonder that they are now becoming the go-to solution for most buildings and houses.
