The inspection and maintenance of expansion joints in roof covering plates should be conducted according to specific conditions. Below are some common inspection and maintenance methods:

Regular Inspections: Conduct regular checks on the roof covering expansion joints for any deformations or issues. Promptly address any problems found. During inspections, verify the sealing integrity of the expansion joints, the condition of the expansion rubber strips, and whether the joints are deformed.

Regular Cleaning: Schedule regular cleaning of expansion joints to maintain cleanliness and prevent debris from entering, affecting their performance.

Replace the expanding rubber strips: The expanding rubber strips are a vulnerable part in the roof covering expansion joints, where they are prone to damage. If signs of aging or damage are detected, they should be replaced promptly.

Leak Repair: If inadequate sealing of expansion joints is detected, it can lead to water leakage. It is essential to address leak repairs promptly to prevent water erosion and damage.
