Spray Polyurethane Foam Roof

Spray Polyurethane Foam Roof Application

Spray Polyurethane Foam (SPF) roofing systems are greatly affected by wind, sunlight, moisture, humidity, and temperature of the roof’s surface. All of these factors can cause damage to the roof, allowing it to deteriorate quickly and potentially fail before the end of its lifespan. Without a strong, flexible, durable elastomeric roof coating, your SPF roof cannot withstand the harsh weather conditions and will cost thousands of dollars in repairs or replacements.

Inland Coatings SPF Roofing Application

The elastomeric rubber roof application manufactured by Inland Coatings has an elongation of over 500% with tensile strength that can withstand over 1,520 PSI, making it one of the strongest, more flexible roof coatings on the market. The durability of the application extends the SPF roof’s longevity while its flexibility protects it from leaks and degradation associated with frequent expansion and contraction. Lastly, the ENERGY STAR labeled coating provides a white, reflective finish that keeps the roof cool and protects the surface from UV radiation damage. Inland Coatings has 12 standard colors and with minimum requirements can provide custom colors to fit your needs.  Overall, Inland Coatings products applied to Spray Polyurethane Foam roofs protect the system from foam loss, provide excellent durability, and save building owners on energy costs.

How to Install Rubber Roof Coating on an SPF Roof System

Our water- and corrosion-resistant rubber roof coating can be used for new Polyurethane Foam or recoating the existing sprayed-in-place SPF system. The foam and coated surfaces must be in good condition, consist of reasonable smoothness, and be free of ridges, bumps, and depressions to best facilitate drainage. For complete installation instructions and guidelines, please refer to the System Specification for SPF document below.

The simple, four-step installation process includes:

  1. Preparing the surface by power washing the roof.
  2. Covering all laps, seams, and penetrations. (Please see warranty requirements for this prep work.)
  3. Applying the roof coating according to manufacturer specifications..
  4. Cleaning up the roof with mineral spirits.

Please contact Inland Coatings for any questions you may have on estimates, product specifications, processes, or warranties.
