How to repair a roller shutter

Investing in roller shutters rather than wooden or PVC shutters brings a certain comfort to a house. They are also more energy efficient, as they fit snugly in the window, allowing the outside air to be blocked. But it happens that the shutter presents a failure, hence the importance of taking care of it and managing to repair it.

The small raptor is customary in European cities where it uses ledges and high cavities to make its nest. If all goes well, this lucky one will be able to see five white baby birds emerging from their shells.

The rolling shutters are obviously exposed to bad weather and temperature changes, two factors that can make them more fragile. Their integrated mechanism causes them to be more complex to retype compared to simple shutters in drink or PVC. Nevertheless, the problems encountered are often identical and there are solutions to repair a rolling shutter oneself.

What are the different parts that make up a roller shutter?

To fully understand how to repair a rolling shutter, it is necessary to be able to identify its different parts. So it consists of:

  • a box: block that protects the shutter when it is rolled up;
  • a bearing: system that supports the axles while ensuring the bearing;
  • an axis: tube on which the fasteners of the apron are fixed;
  • cheeks: pieces on either side of the trunk that hold the axis;
  • a slide: part that serves to guide the slats of the shutter when they go up and down;
  • an apron: set of roller shutter slats;
  • a final slat: the last slat which allows the shutter to be stopped, it is fitted with stops which prevent the shutter from rising any higher;
  • a crank or strap: external part which allows the rolling shutter to be operated.

What are the complications usually encountered on a roller shutter?

Whatever the type of roller shutter, with crank or strap, the objective is, first of all, to identify the cause of the breakdown. The main advantage of owning manual roller shutters and electric shutters is that the failure cannot be related to the motor. It will therefore be easier to repair a roller shutter with crank or strap.

The most common problems are:

  • the apron gets stuck halfway;
  • a flap blade is damaged;
  • the crank turns in a vacuum;
  • the strap or the crank is broken.

Some breakdowns may require professional help. It is therefore possible to repair a roller shutter alone.

How to replace the winch when the crank of a roller shutter spins in a vacuum?

If the roller shutter crank spins freely, the connection system may have come loose or the winch (mechanism that drives the winding shaft) may be broken. Also, as a first step, to repair a roller shutter, it is necessary to:

  • disassemble the trunk to check the condition of the winch;
  • unscrew the apron fasteners at the level of the winding shaft if the winch is to be replaced;
  • unscrew the rod that connects the axle to the crank;
  • dismantle the winch and replace it.

How to replace the strap of a roller shutter?

If the strap is broken, it will need to be replaced. To do this, you must:

  • disassemble the trunk;
  • unfasten the strap and remove it;
  • place the new strap on the retractor;
  • lower the apron with the strap to check that the roller shutter operates correctly.

How to replace a damaged slat of a roller shutter?

It happens that a blade of a roller shutter with crank or strap breaks. In this case, changing the blade is identical for both systems, so you must:

  • open the roller shutter box;
  • remove the apron from the slides;
  • remove the faulty blade by sliding it to the side;
  • replace the damaged blade with a new one by sliding it;
  • refit the apron in the slides;
  • close the trunk.

How to unlock a roller shutter that no longer goes up?

The failure can have multiple causes:

  • the apron is misaligned: the fasteners must be checked and possibly changed;
  • the blades are offset: they can be put back in the axis without forcing, then cleaned and oiled;
  • a blade is broken: it must be replaced as indicated above.
