Our roofdeck in Columbia Heights. It took approximately a week to build, and uses a stairwell from the main floor up to a small loft area for access. Instead of using wood, which must be treated and can stress the roof unevenly, it uses VAST composite permeable pavers and Shoreline vinyl railings, which weigh less and are easier to maintain. Because the roof is nearly flat, we have two in-roof drains installed, which carry water under the decking to downspouts.
