Sealings & Openings – professional repair
Material-appropriate sealing of roof hatches, openings and connections in the caravan workshop.
Sealing overview
Leaking roof hatches, openings and transitions are among the most common causes of moisture damage in caravans. Aging, movement while driving, or improper pre-work can lead to sealing failure.
The repair system enables caravan workshops to seal these areas professionally – without needing to replace entire components or dismantle large sections.
Typical damage in sealing areas
The assessment always takes place in the workshop. Material, structure and damage type determine the suitable sealing method.
Common damage patterns include:
- Leaks at roof hatches and frame transitions
- Moisture ingress at screws and fixing points
- Cracks, shrinkage or detachment of existing sealants
- Damaged transitions between roof, structures and mounted parts
Application limits & requirements
Whether sealing is suitable depends on the damage, roof/wall structure and overall condition of the vehicle.
Requirements include a qualified inspection, assessment of possible pre-damage (e.g. moisture inside the structure) and careful surface preparation according to defined procedures.

Frequently asked questions
Does the roof hatch always need to be removed?
No. Whether removal is necessary depends on structure, condition and damage.
Is re-sealing alone enough?
Not always. Often a complete preparation and renewal of sealing is required for long-term success.
Is documentation recommended?
Yes. Documented work is helpful for customers and for evaluators if required.
