Every time you see long train on the railroad tracks pulling tons and tons of freight down the tracks on the railway cars, transport trailers, auto transport trailers and boxcards...virtually every one of those trailers are made with huck bolted frames. Stronger than welded, simpler to build and much lighter.
Alcoa developed them primarily for use on aluminum Alcoa built chassis and frames, now being used on trucks, busses and general transportion vehicles.
And HuckBolt fasteners meet or exceed the performance of torqued bolts in both shear and tensile strengths. Chances are if your car is 2 or 3 years old it has some huckbolts holding it together!
And membrane roofs are fine, usually having 15 to 20 year warranties...and will likely out last the warranty.
