Roller Shutter issue

[sid1968]

I hope this is the correct place to post

I have a external electric roller shutter. it was working fin until last week my son accidentally gently reversed in to the shutter whilst it was opening. no visible damage ie bent slats etc

Now it does not fully open stops 2 ft from fully opened. iv tried forced pushing it whilst opening still stops 2ft from fully open.

What i have noticed when fully closed the slats looking at the roller box the slats are at a angle not level to the roller box if that makes sense. one end is higher that the other i dont know if that is the problem causing not to opening fully.

I have took the roller box off drilled the rivets. the bar of the shutter are going into side runners with a bolt. I was thinking of undoing the bolt from one side and manually rolling the shutter until the slats are parallel level with the shutter bar rather than being angled

any advice please will be much appreciated

i'd be inclined to call in a door specialist. get it wrong and you could end up with an expensive dent in your car roof.

As above, these things can be dangerous to tamper with, and are a lot heavier than they look.
