While you can use various materials like sand or even just soil, gravel is widely considered the best option to put under a deck. It provides excellent drainage and is resistant to water, fire, and pests. Gravel also helps anchor the soil to prevent erosion during heavy rain and acts as a built-in weed blocker, reducing regular upkeep. Furthermore, it is simple to spread, available in various textures and tones, and adds a polished look that complements any deck design.

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. 

Yes, Ipe is more expensive than Trex decking—both in terms of materials and installation (plus, Ipe trees are endangered). On average, Ipe decking costs $10 to $25 per square foot, while Trex decking costs $5 to $12 per square foot. Because Ipe is harder to work with, the price of installation is higher, too. For Ipe decking, you’ll pay between $20 and $45 per square foot for labor. However, with Trex decking, the labor costs range from $8 to $22 per square foot.

A random orbital sander is best for sanding a deck because it is easier to handle than other power sanders and is less likely to damage the wood. Most decks are made of types of softwood, so a gentler sanding process is essential to prevent permanent blemishes. For example, belt sanders can gouge softwoods.
