Polyurea foam roof coatings form the initial component of spray polyurethane foam-based (SPF) roofs, a prevalent commercial roofing system designed for flat and low slope facilities. Complementing the system, the top coat consists of an elastomeric coating. To explore more about elastomeric coatings, you can click here. Together, this two-part roofing system effectively insulates, seals, and protects your building.
Proper installation
Polyurea roof coatings consist of a combination of two crucial components: isocyanate and polyol. To achieve the perfect mixture, your roofing contractor will utilize transfer pumps and proportion the foam roof coating at a one-to-one ratio for both components. The mixed components are then skillfully applied to the roof deck using a spray gun.
Even application of the foam roof coating is vital to prevent ponding, which could lead to the deterioration of the elastomeric top coating and expose the foam to the elements. However, with proper installation, the risk of ponding is mitigated, ensuring the roofing system functions effectively for many years to come.
”Green” building benefits of foam polyurea roof coating
SPF roofing systems are highly favored for commercial applications due to the exceptional insulating properties of their base coat—polyurea roof coating. In fact, foam roof coatings can offer up to three times the r-value of other insulation types. This results in reduced noise, improved temperature control, and a completely sealed roof.
For green building initiatives, this translates to maximized energy efficiency, minimized energy bills, and overall sustainability benefits. Embracing SPF roofing systems contributes significantly to a more eco-friendly and cost-effective approach to commercial roofing.
OSHA considerations for polyurea coatings
Polyurea roof coatings comprise two primary ingredients: isocyanate and polyol. The first component, isocyanate, poses significant hazards when inhaled. Due to this, the Occupational Safety and Health Administration (OSHA) regulates worksites that employ foam roof coatings as the insulation component for roofing systems. Safety measures are strictly enforced to protect workers from potential health risks associated with isocyanate exposure during the application process.
Preventative Maintenance
Numerous roofing manufacturers advocate, or even mandate, that building owners implement a preventative maintenance program for their warranted roof. In fact, some manufacturers extend their warranty if a maintenance plan is in place. As roofing systems age and mature, prioritizing preventative maintenance today can result in significant cost savings on major capital expenditures in the future. By proactively investing in maintenance measures now, building owners can ensure the long-term performance and durability of their roofs, avoiding the need for expensive repairs or replacements down the road.

Choosing a Roofing Contractor
Roofing contractors utilizing polyurea coatings on their worksites must be well-informed about OSHA guidelines, which outline three essential “employer responsibilities.” These responsibilities include fully disclosing and communicating all potential hazards to employees, providing comprehensive training on the safe application of polyurea roof coatings, and implementing an appropriate exposure control system. An experienced roofing contractor will have a thorough understanding of the OSHA guidelines and will be capable of establishing a safe installation environment within your facility. Prioritizing adherence to these guidelines ensures the safety and well-being of employees involved in the roofing process.
