Water leakage from roofs and ceilings is one of the most common problems faced by homeowners and building managers in Malaysia. With our tropical climate bringing heavy rainfall and high humidity, roof systems are constantly under pressure, making them vulnerable to damage if not properly maintained.
What Causes Water Leakage from Roof or Ceiling?
Water leakage can occur due to broken roof tiles, corroded metal roof, blocked gutters, poor installation, or a lack of maintenance. On flat roofs, water often seeps through hairline cracks, creating hidden entry points that allow moisture to penetrate ceilings and walls.. Because the causes of roof leakage can vary, choosing an experienced contractor is crucial. Only a professional with years of expertise can accurately inspect, diagnose, and recommend effective solutions to stop the problem from recurring.
How to Find the Source of a Leaking Roof
Finding the source of a roof leak is not always straightforward. On flat roofs, the first visible signs often appear as ugly yellow stains on the ceiling, which indicate that water has been seeping in for some time. In areas such as car porches with concrete ceilings, water may travel along beams before becoming visible, so tracing the trail of dampness is best done during or right after rain.
For homes with plaster ceilings, the challenge is greater because the leak is hidden. While some contractors may suggest cutting open the plaster ceiling, Nano-G waterproofing experts use advanced thermal detection devices to pinpoint leaks without damaging your ceiling.
Other common signs include blistering paint, discoloration, and peeling surfaces. While these indicators can help you identify potential problem areas, the most reliable way to inspect and resolve the issue is to engage a specialist who has both the tools and the experience to conduct a proper inspection.
How to maintain and repair flat roofs?
Flat roofs in particular require more attention and maintenance compared to sloped roofs. Their minimal incline makes them prone to collecting leaves, branches, and other debris that trap moisture and accelerate wear. If not removed, this buildup can strain the structure, block drainage, and create the perfect conditions for leaks and water damage.
Regular cleaning and inspections are essential to preserve the roof’s integrity and extend its lifespan. Beyond routine maintenance, applying a protective coating is one of the best ways to prevent future leakage. Nano-G’s hospital-grade nanotechnology waterproofing coating is specifically designed to strengthen roof surfaces against Malaysia’s harsh weather conditions, including heavy rain, intense sunlight, and fluctuating temperatures.
By forming a durable barrier, the coating seals small cracks, prevents blistering, and significantly improves the roof’s resistance to water seepage. Because it is odourless, non-toxic, and quick to cure, it can be applied efficiently without disrupting daily life in homes, businesses, or even sensitive environments such as hospitals.
