What are the Benefits of Spray Foam Roofing

If you haven’t considered spray foam roofing for your commercial building before, it might be time to give it a shot. This option is ideal for restoring or reinforcing an existing roof, giving it a more durable and insulated exterior. To figure out if this renewable roof replacement is the right option for you, here are a few advantages of spray foam roofing to consider. 

First, What is Spray Foam Roofing?

An even layer of foam is sprayed across an existing roof, reinforcing it against leaks and external damage, while adding insulation. Spray foam roofing starts as a liquid, composed of two highly reactive chemicals: polyol/resin and isocyanate. These two chemicals pumped separately, come together through a high-pressure and heated hose. Once sprayed onto a roof, this mixture expands into a foam up to 20x its size, eventually forming a 1-1.5 inch thick layer. Once spray foam insulation installation is complete, it becomes a waterproof and weather-resistant covering that insulates for years.  

Benefits of Spray Foam Roofing

If you’re looking to re-roof, or add insulation to your existing commercial roof, spray foam has quite a few things going for it! Benefits include:

 

  • Renewable – Once you spray your polyurethane foam, you’re able to easily re-coat it. Depending on the amount and type of UV-blocking coating applied at time of initial installation, your roof shouldn’t need to be recoated for up to 20 years. However, in the event that it needs a touch up, it’s easy to do so.  
  • SeamlessSpray foam insulation doesn’t have any seams or laps, where leaks are prone to occur. It’s effective against any sort of penetration, regardless of your commercial roof’s shape.  
  • High R-value. Of all of the roof insulation options, spray polyurethane foam has the highest R-value. R-value denotes how insulating a material is. The higher the number, the better the insulation, the lower your energy cost! 
  • Soundproofing – These added layers on your roof minimize sound coming from overhead, adding an element of peace and quiet to your day-to-day operations.  
  • Quick Installation. A foam roof can be finished quickly, with few workers and without interfering with day-to-day activities in your commercial building.
