If the hearth ends against a wall, you can use a tile cutter as you normally would. However, if the edge of your hearth ends with no surface pressing against it,you may want to look into rounded tiles. These give a smooth edge to your hearth and make sure cut edges aren’t visible. You can also see if the tile you have has pieces that have been glazed or rounded on one edge. You’d then cut the tile and place it normally, with the cut edge facing inward. 

You can, in theory, tile your fireplace hearth with most tiles. However just because you can, doesn’t mean you should. For example, it’s much better to use unglazed tiles because glazed tiles are more resistant to cracking under extreme heat. Porcelain is more heat-resistant than ceramic, but you can still design the hearth as you like by putting the most heat-resistant tiles directly under the fire and, if it matches your style, add more decorative tiles further from the center of the fire. 

Glass tile can cost as much as or more than other durable tile types. When choosing the right tile for you, knowing the advantages and disadvantages of each can help you make an informed decision. The pros and cons of glass tile include:

Pros

• Light-reflecting to add brightness

• Waterproof and mold-resistant

• Made from recyclable materials 

Cons

• High cost compared to similar and more durable materials

• Usually requires professional installation

• More easily scratched compared to materials like ceramic and porcelain

One major drawback of a concrete tile roof is that the material is heavier than most other roofing materials, so there’s a good chance you’ll need structural reinforcements for your home before you can install the roofing material. Concrete tile roofs are also twice as expensive as asphalt shingle roofs, so even though they last much longer, you’ll see higher up-front costs and lower overall value from concrete roof tiles.
