Normal wear and tear, damage from storms or falling trees, and any modifications you make to the building after delivery. If you add electrical, insulation, or shelving on your own and something goes wrong with those additions, that's outside the warranty scope.
The warranty is about how the building was built, not what happens to it afterward. Take care of it, keep it on a good foundation, and the building will hold up its end of the deal for a long time.
