Special Considerations for Polyurea Foam Roof Coating Application

Polyurea foam roof coatings are the first component of spray polyurethane foam-based (SPF) roofs, a popular commercial roofing system for flat and low slope facilities. The top coat is an elastomeric coating. To learn more about elastomeric coatings, click here. Together, the two-part roofing system insulates, seals and protects your building.

Here are several special considerations that your roofing contractor must keep in mind when it comes to applying foam roof coatings:

Polyurea roof coatings are made of two components: isocyanate and polyol. Using transfer pumps, your roofing contractor will perfectly proportion your foam roof coating at a one to one ratio for the two components. Then the components are mixed in a spray gun and applied to the roof deck.

The foam roof coating must be applied evenly so as to prevent ponding, which can deteriorate the elastomeric top coating and expose your foam to the elements. With proper installation, though, the risk of ponding is alleviated and the roofing system should function properly for years to come.

One reason SPF roofing systems are so popular for commercial applications is because the base coat of the two-part system—polyurea roof coating—is an excellent insulator. In fact, foam roof coatings can have up to three times the r-value of other insulations. This reduces noise, improves temperature control and seals the roof completely.

For green building, this means maximized energy efficiency, minimized energy bills and overall sustainability.

The two main ingredients for polyurea roof coatings are isocyanate and polyol. The first of these—isocyanate—is highly hazardous when inhaled. As such, the Occupational Safety and Health Administration (OSHA) regulates worksites that use foam roof coatings as the insulation component for a roofing system.

Roofing contractors that use polyurea coatings on their worksites need to be aware of OSHA guidelines, which outline three ”employer responsibilities”: fully disclose and communicate all potential hazards to employees, train your employees in how to safely apply polyurea roof coatings and establish an appropriate exposure control system. An experienced roofing contractor will understand the OSHA guidelines inside and out, and be able to establish a safe installation environment in your facility.

What Our Customers Say

Excellent service from the entire Wildwood team. I live out of state and they took care of my property through the entire roofing & siding process. Highly recommend.

Jennie Barker

Wildwood was recommended to me by a neighbor. They were very responsive to my request for an evaluation of storm damage. When the insurance company declined to replace my roof, Wildwood worked with me to repair the damage in a timely and affordable way.

Vickie Cochran

Luke did a fantastic job from start to finish. Easy to work with and did what they said. Also helped when additional damage was found. He did an A+ job as far as I am concerned

Gary Potter

After the hail storm back in April of 2023, we needed to hire a roofing company. Immediately following the storm, there were lots of people knocking daily on our door from various roofing companies I never heard of. I went with my instinct and called a reputable company that I heard of and was referred to, which was Wildwood Roofing & Construction. Doug Lake from their company showed up as promised, assessed everything and prepared a proposal that included the repairs needed and suggestions. He then went over it with me and my wife, was very honest about what he would do and helped us choose the best look, quality and durability. We are SO GLAD we hired them. The roof was installed and the installers took extra precautions to protect our windows, deck and driveway. They also cleaned everything up that day and came back the next to check it again and do a follow up call. Doug also sealed up a light for me that had nothing to do with the roof, but it was concerning me, so he fixed that too. Doug handled everything with the insurance company and kept me informed of the process. Great company, very professional and caring about the customers property. I HIGHLY RECOMMEND THEM to anyone needing their roof replaced.

Robert Barger

Professional and up front about costs and scope of repair. Had a couple of companies provide estimates, and Wildwood Roofing and Michael Burnett was the only service that did not try to sell additional products or try to get me to replace my entire roof.

Jeremy Scott

Wildwood Roofing came through on a VERY tight schedule whileworking around some STL winter temperature swings. Employees were great to work with. Met all my expectations.
