For most homes, a new roof is a choice among three steep-slope families: asphalt shingle, standing seam metal, and tile in clay or concrete. Each is a genuinely good roof in the right situation, and none is simply the upgrade of the others. The decision is a fit between the covering and your particular house, budget, and how long you plan to be under it.
The service-life figures in this guide are typical industry ranges, the same ones the roof systems library publishes. They vary with climate, installation quality, detailing, and maintenance, which is why every one is written as a range. A range starts the conversation; an inspection of your actual roof finishes it.
One rule outranks taste: tile is a structural decision before it is a color decision. If the framing cannot be verified to carry the weight, tile is off the table, and that answer comes from an inspection, not a preference.
