For the finished roof deck surface we are using ceramic tiles set on a pedestal system directly on top of the waterproof Kemper roof membrane.
We used a snow-melting pedestal system to provide continuous access to the hot tub and to minimize flat-roof snow-load through the winter. The system allows for hydronic tubing to be run through insulated trays under the ceramic pavers. The house boilers will, via a heat exchanger, maintain a warm flow of glycol through the tubes to warm the pavers and to keep snow from accumulating on the walking surface.
