Single-ply roofing is popular in modular construction due to its durability, long lifespan, and energy conservation. It is also one of the most preferred materials for flat roof applications, especially when dealing with lightweight, cost-effective fast-track projects. RPW Modular Roofing Solutions is the top provider of modular roofing systems, delivering high-quality, cost-effective, and environmentally friendly solutions to clients. It specializes in supplying single-ply roofing products for modular construction projects.

“We are dedicated to serving the modular construction market by offering top-of-the-line products, proven accessory products, and technical support services,” says Amanda B. Whaley-Gilmore, president of RPW Modular.

Gilmore has over 20 years of experience in the roofing industry and has honed her skills in modular construction, an area revolutionizing the process of designing, constructing, and managing buildings. Under her leadership, RPW Modular offers services that cater to all single-ply roofing membrane options, ensuring that clients’ roofing needs are met regardless of the scale or type of project.

The company offers 13’ wide PVC seamless sheets made with high-quality Evaloy KEE PVC membrane, specially crafted for virtually seamless installation. The white PVC membrane is a proprietary formulation that blends DuPont™ KEE (ketone ethylene ester) and PVC to offer superior UV performance and the highest chemical resistance in a single-ply roofing product. These PVC membranes are designed with testing procedures that include internal and external ratings for volumetric modular. This is the only product line in North America that undergoes testing of this nature.

The company also offers black PVC KEE membranes that have all the key benefits of the standard white C3 PVC-KEE membrane and are the perfect solution for areas where white isn’t appropriate. The matte finish is perfect for airports and other high-traffic areas where glare must be kept at a minimum. RPW Modular supplies thermoplastic polyolefin (TPO) and ethylene propylene diene terpolymer (EPDM) membranes that can be custom fabricated to suit the client’s project and has developed a cost-effective sacrificial roofing product for internal layers.

It designs accessory products compatible with all single-ply membranes, unlike others that are specific to certain product types. The company also offers technical support services for builders who may be unfamiliar with the latest building and roofing codes as testing standards become more prevalent in the modular industry. An illustrative example of its capabilities can be seen in the following example: One of its clients, embarked on a project a few years ago that involved using insulation boards on their exterior roof for the first time. This involved a complex two-layer installation process, for which RPW Modular provided guidance and support to ensure proper execution. In fact, an RPW Modular technical representative was sent to the site to provide hands-on assistance throughout the process.

The company has also received positive feedback from project managers who appreciate its rapid turnaround times. A client, NRB Solutions, contacted RPW Modular for truckloads roof foundation boards within 48 hours, a turnaround time that typically can take several weeks. The company met their request promptly with the help of its colleagues and vendors across Canada and the U.S.

RPW Modular has two major upcoming projects in the pipeline. One of them is reroofing the Canadian Warplane Heritage Museum in Hamilton, Ontario, using the new black C3 PVC membrane. The other project involves assisting Guild Crest in Morewood, Ontario, assisting with all aspects of the roofing construction of these buildings from start to finish.

Its team is readily available to assist clients to alleviate problems before they arise, ensuring a smooth process for builders. It customizes and cuts all panels to eliminate waste and only produces what is needed, reducing materials and time needed for construction. RPW Modular is a prime example of innovation and adaptability that modern construction demands and is transforming the roofing sector for a greater tomorrow.
