Well there are a number of things that are really important:
1. Quality of the product is absolutely paramount. Some sellers do not take care to accurately carry out measurements and so the door may not even fit your garage! There is also the need to have a garage door made from quality materials. Any sort of poor quality or brittle material is likely to become a weak spot for any prospective burglar. Make sure you get a garage door that is quality assured and not a cheap knock-off. After all, one of your most expensive assets - your car, is worth the security checks.
2. ALARM!
Always remember an alarm. If your garage is worth protecting, which it usually is - fitting an alarm to your garage roller door is absolutely key. In most cases the garage is separate or at least distant from the main household and so it is a prime target for burglars. Be sure to fit an alarm to your garage roller door to maximise household security.
