Sometimes the biggest ideas spring from the smallest booths at trade shows, and that's the case with this modular aluminum-planked roof system, which is rated to withstand wind speeds upward of 300 mph. Invented by retired book distributor Carl Jenny, the patent-pending design revolves around interlocking extruded aluminum panels ⅛
inch thick. The system installs from the inside—Jenny says no sheathing or felt are required—and each plank covers the fasteners from the previous one.
Of course, a roof designed to live up to a 100-year guarantee doesn't come cheap; the price fluctuates with that of raw aluminum and puts it in the slate-roof ballpark: at least $900 per 100 square feet for the material (not including installation).
