The Sydney Opera House set comes with many curved white pieces to form the roof. I am concerned about whether buying this set will leave me with useless parts that cannot be easily applied to other builds. Are these roof parts just like the boat hulls in the pirate ships? Or, prior to the Sydney Opera House set, did they serve any common function?

1The curved wedge parts appear in a large number of sets. Even in white. Browse the Bricklink catalog for those parts and you will find a lot of inspiration. If you really like the Opera House you should get it and worry about re-using the parts later. Especially when you are talking about the large 10234 set. It has many very interesting parts.– MetalbeardJun 28, 2017 at 8:10

1Besides, I don't think that there is a common function for 99.8% of all LEGO parts. An umbrella can become a robot foot or a space ship gun within seconds :)– MetalbeardJun 28, 2017 at 8:18

You can see the inventory of the opera house on Brickset.
The majority of the roof pieces you seem to be concerned about are these bow pieces, of which you get 34 pairs and one extra left piece.
These pieces are fairly common and are used typically in cars, boats, planes, spacecraft, and other aerodynamic structures, as well as building roofs, robots, and other objects where you need a curvy shape. For example, the white pieces were used in a Ninjago copter set:
34 matched pairs is a lot of these for a normal person to have, so if you never plan to rebuild the opera house you might not use them all (though you could just consider it a challenge to come up with as many builds as you can that use these). However, the set itself has 2989 parts, so that leaves over 2900 pieces that are not white bows that you can presumably reuse in some other construction.
