Roof strength test explained
This site explains exactly how the Institute of Highway Safety tests the strength of truck roofs. The 1999 to 2016 superduties are at the bottom of the barrel. Very weak.
Good” rating requires a strength-to-weight ratio of at least 4.oo. In other words, the roof must withstand a force of at least four times the vehicle’s weight before the plate crushes the roof by five inches. The higher the number – the better. The steeper the graph in the beginning – the stronger the roof structure and the lesser distance the roof is likely to squish during an accident.
1999 to 2016 SD has a 1.1 rating.
The IIHS testing shows that the aluminum cab of the latest Ford F-150 is significantly stronger than the steel counterparts of the previous generation. We will publish an update when more of the current generation of the trucks are tested.
Force Ratio
IIHS Rating 2015 Ford F-150 Crew 5.85
Good 2011 Ford F-150 Crew 4.72
Good 2013 Toyota Tundra Crew 4.48
Good 2011 Nissan Titan Crew 3.56
Acceptable 2011 GMC Sierra Crew 3.13
Marginal 2011 Chevrolet Silverado Crew 3.13
Marginal 2011 Ram 1500 Crew 2.97

The fact that the F150's roof strength was so much higher in 2011, on a model introduced in 2009, is a bad look for Ford who insisted on using two different cab designs for the 1/2 ton versus the 3/4 and up segments up to 2016.

Exactly. Bodes the question, "Why" and the lawyers say "money" and point their finger at FoMoCo.
What disturbs me (beyond the deaths) is that is going to hurt a great brand. We ALL are proud in our SD trucks and their "strength" and then this. I was shocked to discover that these SD roofs are that weak. Look, I ride a motorcycle and have a convertible VW bug as a "fun car" for the beach. I am well aware of what could happen in a VW roll over but the new Beetle has an emergency pop up device to assist in roll over protection. At least thats something.
