Sport Bar vs Roll Bar
 
Is the factory "sport bar" useless in a roll over? My guess is it works as a roll bar in a slow speed light roll over, and turns to spaghetti in a serious roll over. My '05 has the style that ties the main center bar to the windshield. Is that just to brace the angle of the windshield and mount the plastic seal going around the top of the door? Or does the windshield have enough strength built in it to tie it all together as a roll cage?

I have seen the windshield press up real easy with some loving from a tree. I have a small bit of damage nothing too much, but a mate made his look terrible from a light run in. I would think it is too strong.

I like this set up through, as we have some strong laws on changing your bar in Australia so I like this option for when you go serious wheeling or comps. It is a TBT front section with a removable rear section, with intergrated spare rack.

Because of the strict laws regarding vehicle safety that all vehicles have to go through, I would think that the Windsheild would be strong enough to protect you and your occupants from most (read MOST) rollovers. The vehicle may be a total loss as far as sheetmetal goes, but you should walk away. I personally know 2 people that have walked away (literally) from highway speed rollovers with the stock cage attached to the windshield. If you are going to be dropping the Jeep on its top on a regular basis though (extreme rockcrawling), I would definitely invest in a full replacement cage tied to the frame in at LEAST four places... Hope this gets you thinking in the right direction!

Mine rolled a few years back. Windshield frame was trashed, but did take a good brunt of the roll. The roll bar was badly bowed, but held. You'd never know it was rolled now, except I still have the same roll bar that is now only slightly bowed.

Well to echo some of the sentiments that the other have. DC is subject to NTSB rollover safety regulations for jeeps just like any other vehicles are. So yes all things equal you should survive a traffic rollover.

Now surviving a rollover on a 4.5 or 5.0 trail is a totally different ball game with a stock cage. The tubing used in the factory sport bar is not strong enough to handle those type of pressures that happen when you roll at an angle or on rocks. Setups like the TBT, ORFab and many other bolt in sport cage setups will be safer for you for at least one roll or flop on them, but still have a tendancy to bend/break beyond repair. The best option for your safety is to drop a grand or so and have a fab shop create you a good triangulated frame tied "roll cage".
