It’s possible to walk on a clay tile roof, but you run the risk of breaking or cracking the tiles if you’re not careful, so it’s best not to walk on it if you can avoid it. If you or a contractor needs roof access, be sure to distribute your weight evenly and step on the portions of tile that are also supported underneath, which depends on your tile design. Walking on any roofing material is inherently dangerous, so wear rubber-soled shoes and use safety equipment if you need to access your roof.

If you’re out of spacers for your tile installation, you can use pennies. Each time you place a tile, stick the pennies around the edges (on the sides and the corners). Like working with spacers, you’ll want the same amount of space around each tile before they set.

On average, tiling a shower costs between $1,800 and $5,000, with most people paying around $2,700. The price of this project depends on multiple factors, including the kind of tile you choose, the size of your shower, and labor rates in your area. If you decide to tile your own shower (instead of hiring a professional), it’ll likely cost $800 to $1,400.

While you shouldn’t use thinset mortar on its own as a floor leveler, it can work alongside other products to help level floors. For instance, you could start with a self-leveling compound, let that dry, then apply backer board with thinset mortar to help fully even out the floors ahead of laying tile.
