  Hmm As price is 2.5 time that of competitors, but what competitors? Mind you I fully realize that Titanium is so light yet so strong THAT I was amazed that it would be made as a roof tile.

  titanium for tiles? what a waste of expensive metal, very light. does that mean during a taifuu that we will have light metal projectiles in the air?

  Since when are roof tiles structural? As in, playing a role in holding the building together, as the article implies. This is quite interesting; can someone shed some light?

  Roof tiles aren't structural, but in the traditional Japanese method of architecture, they become a major weakness of the building. They're so heavy that once ground oscillations get the building moving, the momentum of all that moving weight at the top of the structure can bring the whole thing down. Topheavy buildings are not very stable.

  I'm surprised they didn't go with aluminum. Maybe recycled PET or polystyrene to make expanded foam for the bulk of the tile and an aluminum coating just thick enough to stand up to hail. Not as light as titanium, but much less expensive than titanium and much lighter than a clay tile.

  why not the rubber tiles made from recycled tires? They can be shaped and aren't as expensive.
