Natural wood is considered by many the most attractive siding for storage units. But wood exposed over time to water usually rots. Some woods, however, contain natural resins that make them relatively rot-resistant. Cedar is such a wood and very popular as a siding choice for storage units. But even cedar siding is not maintenance-free. Coat cedar with a UV-inhibiting sealer/preservative every other year to protect it from ultraviolet solar radiation. Apply a clear stain, as well, to help preserve its natural beauty.
Sheds are a great investment for any homeowner to have not only to increase the usable square footage of a yard but to add valuable storage space. But this space is only as good as how it is used. By incorporating organization systems and techniques, you can have a shed that works for you.
