ᐅ Removing a roller shutter box? Should the guide rail be taken off as well?

What exactly is torn? Could you maybe describe a bit better what happened and how it happened.

If you remove the cover on the outside, you can slide the shutter out over the guides.

So, the shutter is torn at the top where it’s attached (with the anti-theft device), and at the bottom I want to replace some slats because the holes are caused by hail damage.
So the top slat and three at the bottom need to be replaced.
The shutter is on the upper floor and it’s for a double door, so it’s a pretty large shutter...

If it works to slide it out from above over the guide, can the attachment then also be fixed from the outside on the roller tube?

You need to remove the cover. Then replace the mounting brackets (which are probably broken). After that, raise the roller blind. Then lower the blind slightly outside the track and replace the damaged slats. Finally, raise the blind all the way up again and insert it back into the track. Close the cover.

You probably can’t manage this on your own, in my opinion. Let a company handle it. Hail damage should be covered by the insurance. The problem is, you won’t be able to raise the roller shutter.

You can’t replace the parts without completely unthreading the roller shutter.

Maybe you can unhook the metal strip at the bottom of the slat. I wasn’t able to do that.

Usually, the small upper hook (the one that fits into the roller tube) breaks off.

The springs with break-in protection often look different; they are plastic parts with hinges. It is quite possible that they are screwed onto the shaft. Either these holders are broken, or the hook strip of the top slat, where the holders were attached, is torn. Either way, I would suspect too few holders unless it was broken by strong pulling on a frozen shutter.

I would take a look through the inspection opening. You can often see if there is a chance to fix it this way. One important factor is whether new springs can be threaded in if necessary.

I have already replaced broken springs and slats in two systems (one very old and one fairly new). It wasn’t pleasant but it was doable. In both cases, the openings were accessible from the inside (through the open window between the window and the shutter, not through the box).
