We have a flat 12x12 deck off our master bedroom. It sits on top of our garage. We love it and want to keep it, but it continuously leaks water into the garage below. We've tried everything we can think of, from rebuilding the deck with outdoor tile to adding more drains (when snow melts, the gutters can't seem to support all of the water. We make sure they're always free of leaves, but they still overflow). We're getting to the point where we might just give up. We don't have a large budget for repair, but we're thinking about enclosing the deck completely, or covering it in glass and turning it into a sunroom just to put this leak problem behind us. What are your thoughts? Would this affect the value of our home?
