The SPRI Wind Design Seminar provided an invaluable opportunity for members of the roofing industry to deepen their understanding of roofing assemblies, wind-related standards, and critical design principles. With engaging presentations led by industry experts, this seminar shed light on essential topics while fostering collaboration among attendees. Below, we’ve summarized the key highlights from the event.
Pre-Seminar Video – Laying the Foundation of Knowledge
Hosted by Brian Chamberlain, the pre-seminar video offered a comprehensive primer to attendees, ensuring they were equipped with relevant terminology and background information. Topics included the importance of ASCE 7, the role of FM Property Loss Prevention Data Sheets (1-28 & 1-29), and an overview of ANSI/SPRI standards, both adopted and non-adopted. The video proved to be instrumental, with nearly 90% of attendees confirming it enhanced their overall seminar experience.
Key Highlights from the Seminar
- Introduction to ASCE 7
Presenter: Brian Chamberlain, Carlisle Construction Materials
Attendees were introduced to ASCE 7, the standard that serves as a critical component in the certification of roofing assemblies in accordance with building codes. The session covered why ASCE 7 matters, how it operates, and its role in ensuring accurate and reliable results for wind design calculations.
- Understanding SPRI’s Mission
Presenter: Chadwick Collins, SPRI Technical Director
Chadwick provided insights into SPRI’s mission and membership, emphasizing its efforts to create a platform for addressing critical roofing industry challenges. SPRI’s collective knowledge enables members to operate more effectively in the marketplace while staying ahead in the industry.
- ASCE 7 Adjustments and Accuracy
Presenter: Brian Chamberlain, Carlisle Construction Materials
A deeper dive into ASCE 7 explored its evolution over various versions, focusing on adjustments made to refine wind design accuracy. The session highlighted key considerations for designers to avoid confusion and errors when applying these adjustments to projects.
- FM Property Loss Prevention Data Sheets (1-28 & 1-29)
Presenter: Brian Chamberlain, Carlisle Construction Materials
This session clarified the role of FM standards in the roofing industry. While not part of building codes, these standards are widely used by design professionals, especially for FM-insured buildings. Attendees learned how the FM standards differ from adopted ANSI/SPRI standards and how best to use them effectively.
- Edge Metal Standards – ES-1 & GT-1
Presenter: Bob LeClare, ATAS International
Bob highlighted the significance of ES-1 and GT-1 standards in enhancing the wind performance of edge metal systems. Understanding these standards allows professionals to certify their edge metal assemblies to meet building codes while ensuring long-term wind resistance.
- Ballasted and Vegetative Roofing Systems
Presenter: Brian Chamberlain, Carlisle Construction Materials
Brian reviewed the RP-4 and RP-14 standards, offering guidance on designing wind-resistant ballasted roofing assemblies. The session also introduced vegetative roofing systems, providing strategies for creating occupiable and resilient rooftop spaces, such as gardens and amenity areas.
- Wind Design Practices – WD-1
Presenter: Sean Koren, Holcim Building Envelope
Sean walked attendees through the WD-1 standard, which explains Rational Analysis Methods and securement techniques to address challenges in rooftop areas like corners and perimeters. This standard enables professionals to design roofing assemblies that meet or exceed the required pressures for enhanced wind resistance.
- Field Testing & Substrate Verification
Presenter: Colin Griswold, OMG Inc.
Colin discussed FX-1 and IA-1, two standards that assist in field testing procedures for reroofing and recovery projects. These tests ensure the suitability of roof substrates and adhesives, offering a thorough evaluation of existing materials before the design process begins.
- White Papers – Rooftop Equipment and Internal Pressure
Presenter: Brian Chamberlain, Carlisle Construction Materials
Although not official standards, these white papers address critical design considerations often overlooked in building codes. Brian emphasized the importance of secure rooftop equipment attachment and strategies to mitigate internal pressure effects, which can significantly impact the overall performance of a roof.
