Light-Weight Seismic Strap Wall Flashing
The profile of specific components, their configuration or sequencing, can vary with the roof system, climatic differences, and regional or area practices. Dimensions as shown are recommended minimums and are intended to be approximate to allow for reasonable tolerances due to field conditions.
Attach all flashing membranes at approximately 6 inches-on-center. WSRCA recommends installing seismic straps below the roof deck where possible.
Optional: installation of taper edge extending 6 inches beyond seismic strap. For example, see inset detail. Continuous cleats are recommended when flashing face dimension exceeds 3 inches and in areas deemed a high-wind zone as categorized by local building code.
For sunny, hot, and/or high altitude projects located in winter-time heating climates, WSRCA suggests that thermoplastic single-ply roof membranes and flashing ply(s) be white, or another light color, to provide a reflective surface minimizing heat gain and thermal aging. Certain components as depicted in these details may not be provided by the roofing contractor.
