After doing a recent shift with the truck this is similar to the majority of our commercial buildings. Small warehouse buildings with metal light weight truss construction. On some of the buildings with membrane roofs you can feel every step you take without a fire load underneath. The truck captain I talked to had a very similar tactic. Get to the skylights; open them up, and get off the roof. Our Home Depot has pull handles next to the skylights to quickly open them in a fire situation.
Here is a good roof vent video that goes along with your roof size up. This vent job is done by by some highly trained firefighters on DCFD that do this regularly. One of the biggest things i noticed from this video is obtaining a true assessment of how long this operation will take, and will your building construction / fire conditions support that much time on the roof. http://www.firevidz.com/wordpress/?p=1339
