I did not see the roof extend over the pool. I did see the roof over the areas on the sides where you can sit in chairs at tables surrounding the pool. I will go look at my pictures and get back to you.
It has a retractable roof on one of the pools. The band plays under the retractable roof. The other pool does not. Each pool is roughly equal size. The retractable roof is one the pool closer to the back. It looks like a set of steps above the band area.
