Sorry to see no one has responded to your question. Have you purchased a roof rack for your '16 Edge?
I am searching for a similar solution for my '17 Edge Titanium with Vista Roof. It looks like Etrailer has some recommendations and options from Rhino Rack, Yakima and Inno, including installation videos on a 2015 Edge with Vista Roof, but I will need to continue doing more research before I'm comfortable with buying a roof rack and throwing my two kayaks (39 lbs. each) on top. I also want to get a cargo basket for hauling camping gear (tents, tarps, chairs, etc.) from time to time.
My big concern is the single sentence that seems to govern the load capacity in my Owner's Manual (pg. 226 in my 2017 Edge Owner's Manual - Load Carrying). "The maximum recommended load, evenly distributed on the roof rack, is 100 lb (45 kg)." The manual makes no reference regarding the vista roof though. I have to believe that the max weight capacity would be different between a metal roof and a glass roof. Everyone says "check the owner's manual for the load capacity", but it doesn't seem that clear to me.
I just pulled up the 2017 Escape Owner's Manual and it clearly states:
"The maximum recommended load, evenly distributed on the crossbars, is:
100 pounds (45 kilograms) for vehicles without a moonroof
45 pounds (20 kilograms) for vehicles with a moonroof."
45 lbs.!?! That really scares me.
