Tile Cutting 

You want to know if your tiles are strong enough in the installer can cut through them without any risk of cracking, some products will let you install mounting points through the tile.

However, you should know that the installation is the more complicated installation for many reasons. First of all, the installation crew needs to work on your roof while breaking your tiles. The other reason is that many steps have to be taken to ensure that the installation stays waterproofed as removing the tile for the mount, applying the sealant to the mount, covering the mount’s flashing with tar paper, covering the flashing with sealant, putting on a layer of mesh fabric on top of the flashing, and then putting on another layer of sealant on top of that.

After that, the installer has to cut the hole through the tile, then place it over the mount, and then install a collar with flashing on the top of the mount. Lastly, more sealant should be applied to the collar. Note that the installer must repeat this several times for distinctive rooftop installation.

Tile Hooks

Instead of cutting through tiles, some installation companies make hooks that go around the tiles to avoid the need to cut through them.
