Is the roof designed to handle a roof garden??
I had the same thought Frank. In NJ we live near the beach, which means small lot. Mr. AE loves to garden, and our garden area isn't huge. One year my brother was down from Long Island [his garden could feed a small army], and while sitting out on our deck he spied our detatched garage with a flat roof, and told my husband it would be perfect for a roof garden.
Well, it seems a landscaper lives near my brother, and every garbage day he puts out stacks of big black tubs from trees he's planted. So brother fills his car with them brings them down. You had to see the two of them, like little kids with new toys, filling them with dirt, planting tomatoes, and hauling them up to the roof. Mind you, they're using a step ladder to get up and down.
I think the whole town knows 'the house with the tomato plants on the roof', even though it's in the back of the house.
After a couple of years, the weight of the pots, dirt, etc., got to be too much for the roof, especially after a good rain or snow. Major sag and leaks. Two weeks ago we had to tear off the entire roof and replace everything, even the joists, plus they used 1" flooring plywood before putting down a rubber roof. I mean, there was no discussion about not putting the garden back up there.
For what we spent on that new roof, we could have bought crates of tomatoes for 100 years.
