Chicago Partner Geoffrey Waguespack and co-presenters Anthony Neal and Erik Wetzler will present for the NASP 2026 Annual Conference on November 17 in Austin, TX. This presentation will examine a roof collapse that occurred after a newly installed roof drainage system was constructed contrary to the design documents and applicable code requirements. Attendees will explore how liability was evaluated when a contractor delegated drainage work to a subcontractor, the drainage system was effectively redesigned without formal engineering oversight, and the defendants argued that the owner’s observation of the work constituted acceptance of the defects.
