www.mrca.org — Midwest Roofer 22 TECHNICAL & RESEARCH balancing the arts and sciences of roof design and installations. Author Michael Hensen is a professional engineer and a registered roof consultant with the International Institute of Building Enclosure Consultants (IIBEC). His technical duties for Rimkus include engineering and leadership of the building enclosure consulting practice. Key Takeaways Roof replacement has shifted from simple waterproofing to complex, building science–driven systems that integrate air, moisture, and thermal control. Modern roofing requires careful design, adherence to building codes, and effective coordination among trades to ensure optimal performance and durability. Early insulated systems revealed issues such as vapor drive and thermal bridging, highlighting the need for improved materials and installation practices. Today, designers must balance practical installation challenges with evolving demands for sustainability, energy efficiency, and the multifunctional use of roofs.
