Spray Polyurethane Foam (SPF) has many uses. It can be applied by itself or in combination with coatings. Like any other roofing system, spray foam has both positive and negative aspects to consider.
We believe in total transparency at Exceptional Roofing. When considering a spray foam roofing option, the more information the better the decision you can make.
Benefits of Spray Foam Roofing
The benefits of spray foam roofing are numerous. Here are just a few for you to consider:
- Installation: SPF roofing is easy to install, saving you both time and money. The application of foam is quick and usually with no interruptions of the daily routine to the facility. After cleaning the roof, spray foam can be applied directly over any existing material. SPF is installed by spraying a combination of 2 liquids that expands into a foam. This foam expands over the entire structure and conforms to the shape of the roof.
- Energy Efficiency: Providing the highest R-value of the roofing system options SPF delivers thermal, air, and moisture barriers, meaning the material provides better insulation for your commercial building. Polyurethane foam keeps the heat out during the summer and the cold out during the winter. This reduces costs of heating and cooling for your commercial building.
- Seamless & Waterproof: Seams and protrusions, such as a/c units, are a significant source of leaks. Spray foam eliminates seams all together. Since a spray foam is sprayed as a liquid, it penetrates any cracks, seams, or gaps in the existing roof and substrate.
- Renewable & Sustainable: Spray foam creates little to no waste during its lifetime. In most cases there is little stripping to the existing roof, and SPF is applied directly onto the roof surface. This eliminates the cost of tear-off and the waste that comes with it.
The materials that are used in spray foam is environmentally friendly:
- Low in the Emission of Volatile Organic Compounds (VOCS)
- Ultra-Low Global Warming Potential (GWP)
- Free from Chlorofluorocarbons (CFCS)
- Zero Ozone Depleting Potential (ODP)
Cons of Spray Foam
Though a wonderful roofing option, spray foam does have its negative aspects.
- Limited Contractors: Spray foam has to be done precisely, from beginning to end. The contractor has to have a solid understanding of the chemicals being used and needs to be exact when applying the spray foam. Fortunately, Exceptional Roofing specializes in spray foam roofing.
- Installation Window: The installation of SPF cannot be done when there is the presence of ice, frost, moisture, or visible dampness on the roof. Which means SPF can only be applied during specific weather conditions. Though installation does not interrupt that daily workflow of a building, the weather requirements can leave a slim window of opportunity.
- Overspray: Since SPF is sprayed as a liquid it can get blown on to vehicles, and other surfaces in the surrounding areas. Though unwanted, and the most effort given to prevent, there are no health concerns.
- Maintenance: Spray foam roofs need to be inspected twice a year. Especially after severe weather such as hail storms, tornados, and hurricanes, additional inspections are warranted.
