2025 Convention Session: Key Considerations for Roof Drainage Design (Zamarripa, Patel)

Course Overview
This session was originally presented at the 2025 IIBEC International Convention & Trade Show in Orlando, Florida.  This course includes the following components:

• recording of the live session
• a summative assessment consisting of 10 multiple-choice questions
• two surveys required to claim continuing education credit

Description

An effective roof drainage system is an essential part of every building’s performance. Ineffective roof drainage can result in premature failure of the roofing assembly, including water leakage and damage, and, in some cases, may compromise the structural integrity of the roof. Successful roofing performance requires designers and installers to understand drainage design requirements, appropriate rainfall criteria for sizing drainage components, and recognize installation challenges and common failure mechanisms. This presentation will review recent changes to building code drainage design requirements and present key considerations that roofing designers, specifiers, and installers should be aware of for successful roofing drainage systems. The authors will demonstrate key concepts and requirements using lessons learned from evaluating new construction drainage design challenges, investigating roofing failures, and designing roof drainage repairs.
