Will building inspectors red flag a slot opening in the roof area where nonstop waterproofing underlayment should be placed?
It may be possible that a roofing inspector would red flag a slot opening in the roof deck in an area required to have a waterproofing underlayment from the edge of the roof up to at least 24” inside the exterior wall line (Ref. Section 905.2.7.1 of 2006 IRC). Currently, however, there is no code which addresses a continuous roof penetration in this area of the roof. Air Vent will be working with code and regulatory agencies to address the questions as they arise.
