Rainwater system maintenance

The roof with its accessories is an important and visible façade of the building, protecting the building from the effects of weather and moisture. Pisko products, which improve the operation, use and safety of the building, create a high-quality and functional whole. A properly designed and implemented rainwater system reliably directs rainwater and meltwater to stormwater drains away from the building’s foundations.

Inspections and maintenance

Light and regular maintenance is usually sufficient for Pisko rainwater system. The location of the building and local conditions can significantly affect the amount of maintenance work. Older systems need more regular maintenance. It is recommended that rainwater systems be inspected twice a year.

Regular inspections and maintenance of the rainwater system includes

  • Inspection of the rainwater system
  • Maintenance
    Maintenance measures are carried out based on the observations made in the inspection.

    • Cleaning of gutters, downspouts and rainwater drain
    • Repair of mechanical damages
    • Touch-up painting for minor damages

Light and regular maintenance is usually sufficient for Pisko rainwater system.

Inspection twice a year, in spring and autumn

As a general guideline, rainwater systems should be inspected in spring and autumn, and accumulated leaves and debris should be removed. In addition, after the winter, you should check the fastenings of the products and the tightness of the joints. Any scratches on the paint surface can be repaired with touch-up paint. The position of the gutters should be corrected if necessary and lose fastenings tightened. Regular  maintenance measures ensure the operation of the system and the validity of the warranty.

See maintenance instructions for more detailed guidelines on rainwater system/gutter maintenance.

Don’t forget safety!

Remember to pay attention to safety issues even before starting maintenance work. Wear appropriate protective equipment when climbing on the roof and working at heights. The roof is very slippery when wet. If the roof is steep, high, or in a difficult location, we recommend having the work done by a professional.
