Ceramic tiles only last until a worker goes on the roof and breaks one. In the US, contractors routinely require you to release them from liability of any damage to ceramic tile shingles. Pest fumigation becomes much more of a pain.

That being said, if you want them, you can get them (this is how I know the above), and you can get other options. All of this is orthogonal to stick-frame construction. I've seen copper-roofs on stick-framed buildings even.

In a properly designed house there's almost never any need for a contractor to walk on the roof. Attics are fully insulated and are habitable, etc...
