At the moment, we have used most of the possible roofing materials including tiles, fiber cement plates and metal sheets. With modern materials it is much of a appreciation since all these materials work perfectly if installed right.
One can save money in short term choosing metal roof. It will last 15-25 years. If one desires a more long-lasting roof, quality tiles can be used. Tile roof requires more from the structure and therefore is more expensive but it also can last for the next 50+ years. There are many kind of tiles, cheapest not really providing much more than a metal roof would but quality ones are nice and long-lasting.
Fiber cement plates are also an option. They are maybe a bit more quiet during rain than metal sheeting and replacing a broken sheet is relatively easy.
I personally see the question of roof being more about heat insulation than the material. In tropical climate shadow and proper insulation in modern housing is a necessity and one can save a fair deal of money insulating the roof properly. In the long run it will save money.
