Composite decking requires a solid foundation, substructure, or subframe to ensure stability. This base is typically composed of posts, beams, joists, and footings. The frame's joists can be built from various materials like composite, plastic, timber, or metal, as long as the base can support the deck's weight without shifting. A professional deck builder might recommend installing the frame on a solid concrete base for added durability. The final design and materials for the substructure will depend on your budget, the type of deck, and environmental conditions.

Yes, deck footings typically require an inspection before laying down concrete. While not all local building codes require footing inspection, proper placement ensures a safe and structurally sound deck. An inspector will verify that the deck can adequately hold what you put on top of it., and that the footings have been dug to the correct dimensions.

You can add a roof to most decks, but you need to have it inspected first. If your deck didn’t come with a roof initially, it may not be able to handle the weight without some structural changes. You can add additional supports to your existing deck to safely add a roof, and tying your deck’s roof to an exterior wall can help add some structural stability, but remember these aren’t DIY projects and need to be left to a pro. 

Expect to spend around $10,000 to $11,000 to replace a 20-by-20-foot deck. Using high-end materials like composite or exotic hardwoods can drive up the cost, as can custom features and design elements. You can also expect to pay more than average if your deck replacement requires a site evaluation or if you need the work done during the busy season.
