The main types of shed construction are metal sheathing over a metal frame, plastic sheathing and frame, all-wood construction (wood frame, wood siding and wood roof), and vinyl-sided sheds built over a wooden frame. Each type has various advantages and disadvantages that a homeowner has to consider. For example, while metal sheds are fire and termite-resistant, they can rust over time, or be severely damaged by high winds or heavy snow loads.
