It depends on more than the material
Sun, shade, trees, storms, installation quality and maintenance all affect life. A well-installed, well-kept siding of any type can outlast a poorly installed premium one.
Numbers are typical ranges, not promises.
Vinyl
Quality vinyl commonly lasts several decades. It can fade, crack in cold or from hail and warp if installed too tightly.
Thicker and insulated products tend to last longer.
Fiber cement
Fiber cement often lasts several decades or more, with the finish needing renewal every so often. It resists hail, pests and rot, and it does best with sealed edges and good caulk.
Factory finishes help it hold up.
Wood and engineered wood
Cedar can last many decades with regular finishing and attention to moisture. Engineered wood can also last well when edges are sealed and the boards stay dry.
Neglect shortens both.
Metal and veneer
Steel and aluminum can last decades with little care, though coatings fade and thin panels can dent. Stone and brick veneer can last for generations when backed and flashed correctly.
Their weak point is usually flashing or movement, not the stone itself.
How to extend it
Wash yearly, keep gutters working, trim vegetation, replace failing caulk and repair damage early. A maintenance plan keeps this on track.
Fixing a small problem is almost always cheaper than ignoring it.
Installation quality and maintenance matter as much as the product, so invest in both.
