For nearly maintenance-free storage units, vinyl is the preferred siding. Vinyl lacks the visual appeal of wood, but if you own a house with vinyl siding, why not select a storage unit that is also sided with vinyl? However, vinyl will get dirty over time, making it even less attractive. Mold is often the culprit. Take into account the maintenance required to clean the vinyl periodically.
Price vs. Quality in Outdoor Storage Sheds - Don't let the price of outdoor storage sheds be the determining factor for you. Some shoppers, once drawn to the cheapest price, immediately thereafter put blinders on and ignore alternatives. Outdoor storage sheds sided with cedar and vinyl (the highest quality sidings) are only a few hundred dollars more than outbuildings sided with lower-quality materials. Consider how much those few hundred dollars are buying before rejecting the cedar or vinyl.
