At Superior Seamless Roofing, we have several years of commercial roofing experience; we work with customers every day to decide what kind of roof is best for their facility. While the choice is typically up to the building owner, we want to point out a few pros and cons to Spray Foam Waterproof Roof.

PROS OF SPF ROOFING

Easy Installation

The installation process can save you time and money with your new SPF roof because it is seamless. The application of the foam and coating is really quick and can be applied with usually no interruption to the daily routine of the facility.

 

SPF roofs are installed by spraying a liquid on the existing roof and allowing it to expand into a foam. This process means that the foam forms to all roof shapes and types, even irregularly shaped roofs. After cleaning the existing roof, the SPF roof can be applied directly over asphalt, shingles, concrete, metal, wood and more.

Energy Efficient

SPF roofs deliver thermal, air, and act as moisture barriers to provide the highest R-value per inch, which means the material provides better insulation for the building.

The polyurethane foam keeps heat out in the summer and keeps it inside during the winter, lowering energy costs for facility owners. The silicone  coating resists UV light, protecting the foam and reduces heat absorption.

 

Easy Maintenance

Once an SPF roof is installed, it requires little maintenance. If properly maintained, your SPF roof can last a lifetime.

SPF roofing systems should be inspected in the Spring and again in the Fall. Additional inspections are also suggested following any weather event that might have caused damage to the system.

In the event where a silicone recoating is needed, there’s no tear-off of the existing materials; you apply the new coat on top of the current system.

 

Seamless and Waterproof

 

Seams and penetrations are the primary sources of leaks in roof systems, SPF eliminates this vulnerability.  Since the SPF mixture is applied as a liquid, it fill gaps, seams, and cracks in the existing roof and substrate.

The application of the polyurethane foam or expandothane allows the contractor to level out the roof to decrease the chance of ponding water. The foam material can expand and contract with the building in accordance with outside temperatures, reducing the likelihood of cracks and splitting.

 

Renewable and Sustainable Roofing

SPF roofs create little to no waste during its lifetime. In most cases, there is minimal stripping of the original roof, and the SPF roof is installed on top – eliminating the need for costly roof tear-offs and waste.

 

CONS OF SPF ROOFS

Not All Contractors are Created Equally

 

The application of the spray foam is a process that needs to be done correctly from the beginning. The contractor needs to be precise with the application and have a solid understanding of the chemicals they are using.

It doesn’t take a large crew to install an SPF roofing system, but it requires a high degree of technical knowledge and experience.

Having the roofing system is installed incorrectly, is detrimental to the lifespan of the roof and underlying substrate.

 

Weather Plays A Factor

SPF can only be sprayed during certain weather conditions. Installation of an SPF roofing system cannot be performed when there is ice, frost, surface moisture, or visible dampness on the existing roof.

While the installation does not interrupt the daily functions of the building, the weather requirements can leave only a small window of opportunity.

Overspray Potential

 

Since the SPF roof is installed by a spray application, there is a risk of the wind carrying overspray onto surrounding cars and other surfaces. While this does not pose a health concern, it is a concern for surrounding property.

At Superior Seamless Roofing, we take extra care to prevent overspray. We have a few different techniques that we practice to protect surrounding property.

 

Maintenance

SPF roofing systems should be inspected twice a year whether there is known damage or not. And especially after weather events that could cause damage: such as hail storms, tornados, and hurricanes. Small cracks, gouges, or punctures can be repaired with an elastomeric sealant compatible with the SPF system. So you need to keep your SPF roof in mind at all times.

 

Accurate Repairs Needed

SPF does not have as high of resistance to punctures or damage. If your SPF roof is damaged, you must call an SPF contractor to perform the repair. The repair needs to be made with silicone because typical roofing repair materials do not adhere to the silicone coating.

Spray Polyurethane Foam Roofing Systems are  the go-to roofing solution for commercial, industrial, and manufacturing facilities that are looking for a sustainable, economically efficient option.
