Hey guys, Our master bedroom has a sliding door that walks out to a flat section of roofing. It was obviously planned on being used for a deck but was never finished/built. The roof is covered with rubberized panels. I saw a recent video about using plywood for flooring, and I'm wondering if I could use this as a cheap deck floor. My idea would be to purchase enough external plywood to cover the surface, then cut the boards into 8inch slabs. I'd sand the boards and then stagger them to use as the deck flooring. Looking for feedback on this process. I'm also wondering if I could simply drill these boards directly to the roof, without using an underlying frame. Framing would add a lot of weight to the roof, and it also would also make it so that you'd need to step up from the sliding door - the roof is pretty much flush with the base of the door jam now. Just looking for the cheapest, easiest way to put something down so that we can use the space as a deck. If cutting the plywood into planks doesn't make sense, could we just lay full boards down instead? Most of the area will probably be covered by a large outdoor carpet, and we'd stain/paint the plywood. My only other concern is in regards to the rubber matting - would drilling into this cause any issues with moisture potentially seeping into the roof? Thanks in advance for any suggestions.
