The sandwich roof panel is a construction solution recognized for its longevity and efficiency. However, its direct exposure to the weather requires minimal monitoring to maintain its watertightness and insulation properties. A preventive care plan not only avoids costly repairs, but also ensures that the initial investment retains its value and functionality for decades.
Importance of preventive outdoor care
The durability of the steel and the insulating core can be compromised if external factors that act on the surface on a constant basis are not addressed:
- Ultraviolet radiation: Extreme heat influences the expansion of sheets and the integrity of technical seals.
- Organic residues: The accumulation of leaves or pollution retains humidity, facilitating the appearance of localized corrosion.
- Moisture and leaks: Deterioration of joints is the main cause of loss of thermal efficiency and indoor comfort.
- Accidental loads: Uncontrolled traffic on the deck can cause dents that retain standing water.
Essential technical maintenance tasks
| Technical action | Recommended frequency | Main objective |
| Surface cleaning | Annual | Elimination of sediments and biological debris |
| Anchor inspection | Semiannual | Check fastening and condition of washers |
| Joint overhaul | Annual | Ensure total system watertightness |
| Drains and gutters | Seasonal | Avoiding overflows and water accumulation |
Cleaning and visual inspection protocols
For effective cleaning, moderate pressure water should be used with neutral detergents, always avoiding abrasive products that scratch the pre-painted steel. It is essential to use soft bristle brushes that do not damage the protective anti-corrosion layer. During the inspection, special attention should be paid to the joints and the perforations of the fastening screws.
If signs of oxidation or wear are detected in the sealing gaskets, they must be replaced immediately with compatible materials such as butyl or specific sealants. Likewise, the supporting structure should be checked for movement or corrosion at the points of contact with the panel, ensuring that the stability of the assembly is total.
Critical errors and safety recommendations
Maintenance must be carried out according to strict safety standards and respect for the material. A common mistake is to walk directly on the panel furring; to walk on the deck, the use of walkways or planks that distribute the weight and avoid permanent structural deformations is mandatory. The use of industrial pressure washers at maximum power is contraindicated, as they can lift the seals or damage the surface finish.
Early detection of small cracks or chips allows the application of touch-up paint treatments that slow the advance of rust. Keeping the environment free of nearby vegetation prevents mechanical damage due to friction and constant shading that favors the growth of moss. Performing these actions on an ongoing basis allows the roof to maintain its technical efficiency and original visual appearance.
