Metal roof is very expensive and not easy to install.
Tin roofs are typically made from metal sheets manufactured from various materials such as steel or aluminum. These sheets are coated or treated to prevent rusting and provide durability against weather elements. Modern "tin" roofs may also be made from other metals like copper or zinc.
Both tin roofs and tile roofs have good qualities. Tile roofs are generally the least expensive and come in a variety of patterns and colors. Tin roofs are much lighter and offer greater protection in high wind areas. They are also more fire resistant which may offset some of the additional costs if you plan to stay in the house for several years.
A metal tin roof has many advantages over an asphalt roof. Metal roofs last longer than other roofs, do not deteriorate as quickly, and can withstand more extreme temperature changes. Tin roofs are also less work to install, and can even lower your insurance costs.
I don't know thy there are triangular roofs in Mexico, but I know that there are flat roofs i Mesopotamia, because it gets hot there sometimes, including night, so they'd sleep on their roof for a breeze.
Valley Tin is used on roofs where two roofs section meet perpendicular forming a valley. This creates a transitional for water to drain from both sides of the valley roofs. Two types of Valley Tin can be used, smooth/rolled metal or metal with an inverted V in the center. The inverted V serves to check the water speed on steep roofs to prevent an overshot of water causing a leak in the adjoining roof. Three metals are common in fabricating valley tins. Aluminum, Galvanized Metal & Copper
A tin roof is typically made of sheets of steel or aluminum that have been coated with a layer of tin to help prevent corrosion and provide durability. Modern tin roofs may also be made of other metals like copper or zinc.
It normaly looks the same but if your spanish living in Mexico they have flat roofs. They have flat roofs because it dont snow there we have trianular roofs so the water and snow will slide off.

Probbably because slanted rooftops are designed to shed rain and snow and there is little of that in their region.
Roofs
The three main types of roofs are flat roofs, pitched roofs, and mansard roofs. Flat roofs have a slight pitch for water drainage, pitched roofs have a steep slope, and mansard roofs have two slopes on all sides with the lower slope being steeper than the upper slope.
