A friend of mine asked me to write an article on the subject of green roof gardens the other day. She writes on gardening as I write on home improvement and sometimes we collaborate. It’s a good thing. It sounded interesting so I started digging into research.
I already knew something about the structural needs; when I worked at the Marriott hotel in the Houston Medical Center, we had a good sized indoor swimming pool on the fourth floor. It was supported by massive aluminum I-beams.
And imagine, it was right over the ballroom (third floor). Yikes! One night the graveyard shift engineer was making his rounds and saw that the jacuzzi was empty. He turned on the water to fill it up. What he didn’t realize was that the jets were removed for maintenance.
Long story short - he continued on his rounds. By the time he came back to check, there were about 200 gallons of water on the ballroom floor and the acoustical drop ceiling was ruined. Ouch!
Green roof gardens have similar structural requirements because of the weight load of the dirt. Traditionally, you had to have a flat roof to put one of these babies in. No longer; entrepreneurs have engineered modular systems that allow installation on sloped roofs.
Am I going to do one on my house? Nah; too much work, and I already have a garden on the ground. But if I was building a new home, you bet!
