HOW LONG DO WOOD DECKS, SHINGLES AND FENCES LAST?
When wood is exposed to the elements, its life span depends on the wood species, the degree of decay hazard, the maintenance activities, and the nature of the preservative treatment, if any. Shingles made of naturally durable western red cedar typically last 15-25 years. A well-designed and ventilated cedar deck will have a similar life, as will fence boards. A fence post made of untreated wood and put into direct contact with the ground is one example of a high hazard situation that will lead to a shorter life span. Properly treated wood can last at least 40 years – please see our page Performance Data for field test results on treated wood.
