Hawaii roofs factor in wind, rain and sun. We have a "sunshine" load on our roofs of about 20# per square foot for live load and about 10# per square foot for dead load. Usta be (back before the eighties) we'd run rafters or trusses at four foot on center, plop two by threes across those at two feet on center and nail on roofing tin. That worked until Hurricane Ewa and Iniki and then they changed the codes. Now the roofs have more Simpson ties, closer rafter/trusses and we still fasten tin over the top in most cases.
One of the most important things for a roof in Hawaii is the three foot eave overhang. That not only keeps the rain away from your house but it keeps the sun off the sides of the house as well. Many times mainland house plans don't have any or anywhere near enough roof overhangs and the resulting structures are miserable to live in.
