15) How easy is it to roll?

Very! Usually 2 people would push or pull the system and in seconds the enclosure is open or closed. If it's a bigger system it may take a couple of minutes by moving each section separately until the entire system is opened or closed. The retractable sunroom models often require just one person to open it and close it. It depends on the depth and rear wall height so when your system is being designed please don’t forget to ask on how well your systems going to roll with one person or two. As a design note, the wider the bays the better it rolls, as well, that is one of the reasons that we developed a 7’ wide bay so that you get easier opening process than a narrower bay.
