A Practical Guide to EPDM, PVC and TPO Roofing Technologies
Sponsored by SOPREMA, Inc. | Presented by Evan Letner
Live Webinar Airing on December 3, 2026 at 02:00 PM ET
Explore the technology, history, and benefits of single-ply roof systems, with a core focus on EPDM, PVC, and TPO membranes. This course examines the evolution of these roofing technologies, their material characteristics, and the performance benefits each can provide within modern roof assemblies. Attendees will gain a better understanding of how EPDM, PVC, and TPO systems differ, including key considerations related to durability, energy efficiency, installation, maintenance, and long-term performance. The course will also address factors architects and design professionals should consider when evaluating and specifying single-ply roofing systems for different building types, climates, and project requirements.

Evan Letner began his career with SOPREMA nine years ago on the Information Technology team before transitioning into the Inside Technical Department, where he developed a strong foundation in roofing, weather resistive barriers, and below-grade waterproofing systems. During this time, he worked extensively with third-party testing agencies, helping build and evaluate test assemblies while gaining firsthand knowledge of system performance and industry standards. He also developed expertise in warranty processes through the preparation and review of Notice of Intent to Warrant documentation. For the past two years, Evan has served as an Architectural Sales Representative, supporting architects, consultants, and building owners throughout a five-state territory. His technical background, combined with field and specification experience, allows him to provide practical, system-based solutions for complex building envelope challenges. |
