Flat Roof Patio
I have a suspended slab flat roof/ patio over the front entryway of the house I just purchased. The roof had leaked and a large part of the framing has rotted. luckily the exterior of the house is block and that the slab is supported by it. As a carpenter, the framing should be relatively straightforward. The concern i have is how to prevent the roof from leaking in the future, but still retain the patio. I read an article in FHB about decking over rubber roofing. I’m considering installing rubber roofing, than covering it with a layer of sand and laying concrete tile. Does anyone see a problem with that?

Pennsylvania. That's why i'm considering doing it that way, we build patios this way all the time. the tiles can heave but settle well in the spring. we use polymeric sand as grout. does a pretty good job
well, my reservations are that this system will retian water and turn to ice which is damaging to roof and flashing systems. Sand is also abrasive on that rubber. There might be a soft sand that is more compatible.Ditra's Manufacturere has a system designed for applications like this that facilitates drainage

Has anyone evewr used liveroof
This summer I renovated a flat carport roof for clients who wanted a no maintenance surface. I used 18" patio stones on small plastic discs (sorry I don't know the product name) that provide a drainage space between the pavers and the membrane. It also allows easy access to the membrane for inspection and repairs. The roof structure did have to be beefed up as each paver weighed about 70 lbs, adding a significant load.
