Moisture is possibly the biggest enemy of your shed’s floor system. Think of all those spring rain showers, the early morning dew, the summer humidity and melting winter snow. It’s clear that moisture is difficult to avoid, but prolonged exposure could be detrimental to your shed’s durability.
Some shed buyers quickly discover their shed's flooring may not be as durable as they thought when they made the purchase. They ask "Why is my shed floor rotting?!" The simple answer is that their shed wasn't built to withstand the moisture that is unavoidable in any backyard.
This is why it's essential to know how your shed floor is constructed. Your belongings are valuable and need a secure, durable floor that will protect your things.
