Proper and timely maintenance of a flat roof is essential to extend the lifespan of the roofing system and to ensure lasting waterproofing performance. Regular roof maintenance also ensures efficient rainwater drainage and helps detect and prevent damage or leaks at an early stage.
The following steps are generally recommended during a standard maintenance check of a flat roof:
- Cleaning the roof surface: Remove leaves, dirt, and other debris that could obstruct proper drainage.
- Inspecting and cleaning rainwater outlets: Ensure all outlets are free of blockages, and apply a corrosion-resistant coating if necessary to prevent rust.
- Inspecting roof waterproofing: Carefully examine all visible waterproofing details and carry out minor repairs to limit damage.
- Checking flashings and profiles: Inspect whether flashings and edge trims are still properly installed and reseal them where needed.
- Checking rainwater drainage capacity: During the first maintenance inspection, it is important to verify whether the existing drainage system complies with current standards. This helps prevent structural overload due to water accumulation.
