About this detail

This parapet detail shows a roof deck assembly with a vertical guardrail mounted against the exterior wall. The roof features pavers on pedestals over a protected roofing membrane, R20 minimum rigid insulation, a roof vapor barrier, and R20 minimum spray foam insulation below. The parapet wall is topped with a twenty-two gauge metal coping with standing seams, installed over self-adhering membrane high temperature underlayment and a four-inch minimum fastener spacing with a neoprene washer and shim. The exterior face includes furring, a primary water-resistive barrier, self-adhering weather-resistive barrier liner, liquid-applied flashing, rod and sealant, and siding per elevation. A slope to drain of three-quarters of an inch per twelve inches minimum is provided at the top of the parapet, and one-quarter of an inch per twelve inches across the roof deck.
