Application Methods & Procedures

EPDM Single-Ply Roof Application

Though durable, EPDM single-ply roofs can develop leaks at the seams and penetrations. These membranes can also develop punctures and tears due to prolonged exposure to foot traffic and careless roof maintenance. The best way to maintain and protect your EPDM roof is to apply the proper elastomeric roof coating.

Inland Coatings EPDM Single-Ply Roofing Application

Inland coatings has developed an elastomeric rubber roof coating to seal and reinforce the existing membrane, protecting it from UV radiation and eliminating leaks. The flexible, synthetic rubber roof membrane is water resistant, and it also resists damage caused by high and low temperature extremes. Our liquid rubber application can be used for mechanically fastened or fully adhered single-ply EPDM roofing systems.

In addition to the improved durability our product offers existing roof systems, the liquid rubber roof coating is also highly reflective, earning an ENERGY STAR label for is efficiency. The white, reflective finish coat keeps the building cooler by minimizing the roof’s surface temperature. By reducing heat-related expansion and contraction, our roof coating minimizes stress at seams and fasteners, keeping them stronger for a longer period of time. Inland Coatings has 12 standard colors and with minimum requirements can provide custom colors to fit your needs.

Liquid Rubber Installation

Please note that the Inland RC-2000 and RC-2200 are solvent-based products. Exercise extreme care when applying them over EPDM membranes to prevent wrinkling on seams and other surface areas. Please follow the application rates and procedures outlined in the step-by-step instructions below. Due to the high reflectance and cooling effect of Inland’s liquid rubber products, make sure to evaluate the building envelope to confirm the insulation and vapor barrier are adequate to prevent condensation on interior surfaces.

EPDM Restoration Process

Be sure to review all guidelines and instructions below before starting the EPDM roof restoration process. In summary, the entire coating application can be broken down into four steps:

  1. Prepare the surface by power washing the roof, making sure it is clean and cleared of all debris.
  2. Cover all the laps, seams, fasteners, and penetrations.
  3. Apply the coating according to product and warranty specifications.
  4. Clean up all spills, tools, and equipment so the jobsite is cleaner than how you found it.

Please contact Inland Coatings for any questions you may have on estimates, product specifications, processes, or warranties for EPDM single-ply roof applications.
