This detail illustrates a low roof terminating into a higher wall. The tall interior single-wythe CMU wall transitions into an anchored veneer wall above the roof line. The open web steel joists of the roof structure bear on the tall CMU wall via a steel bearing plate on a CMU bond beam. The roof system terminates with counterflashing that engages with a sheet metal receiver within the masonry wall, providing moisture protection for the wall and roof assemblies while allowing each assembly to be independent of the other. Insulation and air/moisture/vapor barrier are continuous across the masonry and roof systems, providing defense against thermal and moisture transfer. A system of flashing and weeps above the roof line allows moisture to exit the drainage cavity, and an optional cavity drainage insert protects the weep vents from becoming obstructed.
