Water leakage from rooftops is a common problem in buildings, with complex and varied causes. Owners are responsible for the maintenance and management of their properties, including addressing leakage issues. If you suspect that the source of leakage is from the unit above or a neighboring unit, you should discuss it with the relevant residents as soon as possible, requesting an investigation into the cause of the leakage and the necessary repair work to resolve the issue. If necessary, hire building professionals or legal advisors to require the responsible parties to stop the leakage according to the provisions of the building's Deed of Mutual Covenant, and even make claims if needed. Common causes include but are not limited to the following points:
The main purpose of waterproofing on rooftops is to prevent rainwater from penetrating the interior of the building, thereby protecting the structure from damage. Without effective waterproofing treatment, long-term water immersion can lead to the following problems:
Structural Damage: Moisture penetration can lead to the corrosion of concrete structures, affecting the stability and safety of the building.
Indoor Humidity: Leaks can cause indoor humidity, affecting the health of the occupants and potentially leading to mold and bacterial growth.
Increased Repair Costs: Once a leak issue arises, the repair costs are often higher than the investments in preventive measures, making it wise to carry out waterproofing work early.
