The Pros and Cons of Spray Polyurethane Foam

Spray Polyurethane Foam or SPF is one of the most common options offered by commercial roofing services. It is a type of roofing material that is sprayed onto the existing roof surface as a liquid and gradually expands into a solid foam layer that covers the entire roof. Even though its application in residential roofing is not that widespread SPF roofing has been popular in industrial and commercial sectors for quite some time. It can be used in any type of weather and can last for more than 50 years with proper maintenance. Below is a quick look at some of the pros and cons of SPF roofing.

Advantages and Disadvantages of Spray Polyurethane Foam

SPF roofing is known for its great energy efficiency capabilities. It can act as a good barrier against heat, air, and moisture, and can deliver the best R-value per inch by providing a supreme insulation solution. The durability of SPF roofs is also much better than other traditional roofing options. As the material expands and contracts along with the changes in the temperature it significantly reduces the likelihood of cracking and splitting.

Applying SPF as a liquid to the existing roof makes sure that the gaps and cracks underneath are properly filled. The roofing system that you get from SPF does not involve any joints or seams which in turn ensures that the roof’s surface is flawless and well protected from leakages. Moreover, professionally installed SPF roofs can easily withstand the weight of a person and they would not become damaged even if someone walked on it.

Another great advantage of SPF roofing is that they are totally eco-friendly and do not produce any kind of excess waste or cause harm to the environment. In fact, there are many different kinds of SPF roofing products that are environmentally friendly such as those with ultra-low global warming potential, solvent-free silicone, and zero ozone depletion potential coating.

The main drawback of SPF roofing is that it cannot be installed in the winter season or during windy or rainy weather. SPF roofing is also prone to punctures and mechanical damages. Aside from that, the existing roof should be properly dried as well before spraying the SPF material onto it. This means that you must hire an expert commercial roofing service provider to get the job done correctly. Remember that if your SPF roof is not installed properly it won’t last for nearly as long and can incur even more maintenance costs.
