Which garage door components are most likely to wear out first?

Torsion springs, rollers, and cables wear out first since they do the most work every time the door cycles. Torsion springs are typically rated for around 10,000 cycles, roughly 7 to 10 years for an average household, and tend to fail without much warning. Rollers and cables wear more gradually, showing up as noise, sagging, or a door that runs unevenly.
