Ipe deck tiles are a great solution for covering a flat roof.

I like that design

Second what Colorado Cottage & Deck said. Ipe Deck tiles (or any other Brazilian hardwood) will do great even in cold environments like Colorado. The advantage of these tiles is that they can be floated right on top of your roof without needing to penetrate any membrane. If you must raise them. most deck tiles, including ours, work with pedestal systems. Otherwise, using connectors like the Deck Wise tile connectors will suffice!
