Changing to a new type
There are a variety of different styles of garage doors, each bringing its own benefits. After learning about these, you may find that you would prefer having a different style of garage door. For example, if you want more headspace in your garage, a sectional garage door might suit you better. This can be especially useful if you have recently bought a new car that's considerably bigger than your previous one. Another example would be upgrading from a manual garage door to an electric garage door, or from an electric garage door to an automatic garage door.

Your garage door is getting old
Over time, your garage door will accumulate wear and tear. Whether it's worn down parts, chipped paint or rusted metal, the looks and functionality of your garage door will inevitably degrade. This can be mitigated significantly with proper maintenance, part replacements and repairs; however, it will eventually get to the point where your garage door starts to show its age.
At what point your garage door is too old will largely depend on personal preference; some people are content so long as their garage door 'works'. For many people, however, a garage door looking old is a completely valid reason to replace it with a new one. An old garage door can have a negative impact on how your home looks. Not only is this unenjoyable, but it can also reduce the value of your home. Between this and the costs associated with maintaining an old garage door, buying a new garage door may even end up saving you money.
Making your house look better
A garage door takes up a significant portion of the facade of your home, making it a key stylistic feature. What's more, with the diversity of styles, materials and colours that garage doors have, there are endless ways that a garage door can look. Because of this, when properly utilised, a new garage door can completely change the look of your home.
If you place a lot of value on the aesthetics of your home, it is seriously worth considering how your current garage door contributes to or takes away from that. This is especially true if you're already making changes to improve how your home looks.
Damage
One more reason that you may want to replace your garage door is if it sustains significant damage. If you're in this situation, look into the price difference between repairing and replacing your garage door. If you are going to have to spend money on the repairs anyway, you might want to take the opportunity to replace your garage door for one of the above reasons. In some cases, repairs may not even be an option; in this case, you should make sure that your replacement garage door is the right one for you.
