Low-slope garage roof deck
I’m looking to add an attached unheated garage with a rooftop deck. Slope will be 3/16″ per foot one direction to a gutter, and thinking sidewall-mounted rails to keep the roof membrane unpunctured.
The struggle is what’s above the membrane. Multiple contractors I’ve spoken with have only done wood decking fastened to treated lumber sleepers laid directly on the EPDM. I’d prefer a more durable solution. My hairbrain idea was 12″sq. composite deck tiles w/ interlocking mat, some landscaping rock around them, all floated on top of a drainage mat w/ filter fabric rolled onto the membrane.
Has anyone installed something similar? Or know of other durable roof deck options? Thanks in advance for any thoughts.
