A critical and often overlooked design detail is at the termination of a parapet coping at a wall.
Terminating brick veneer on low roofing.
Veneer ties shall be corrosion resistant metal capable of resisting in tension or compression a force equal to two times the weight of the attached veneer.
Roof wall interface detail anchored brick veneer cmu backing.
The open web steel joists of the roof structure bear on the tall cmu wall via a steel bearing plate.
With solid masonry walls it s enough to secure the roofing membrane with a termination bar and counterflash with metal let into a mortar joint above the membrane.
This detail illustrates a low roof terminating into a higher wall.
Below is a sketch of what the flashing at roof to wall intersections should look like.
If made of sheet metal veneer ties shall be not smaller in area than 0 0336 by 1 inch 0 853 by 25 mm or if made of wire not smaller in diameter than 0 1483 inch 3 76 mm wire.
This detail illustrates a sloped roof terminating into a higher masonry veneer wall.
The exterior wall covering material is then kept off the surface of the roof.
The tall interior single wythe cmu wall transitions into an anchored veneer wall above the roof line.
Above the roof a series of short masonry flashing components4 are mechanically fastened to the backup wall using a termination bar with continuous sealant5 along the top.
This way each time in the future when the roofing material is replaced the stucco brick or stone veneer will not need to be cut out and replaced.
Outside face of the veneer through the thickness of the brick veneer across the air space to the backing and then up behind the water resistant barrier or attached over the water resistant barrier with a termination bar.
Where more than one piece of flashing is required flashing pieces should be overlapped and sealed with a compatible mastic.
