Why Skylights Waterproofing in Singapore Matters
Singapore’s weather is unforgiving. With intense downpours, high humidity, and year-round heat, skylights are constantly exposed to stress. Without proper waterproofing, you may face:
- Water leaks that damage ceilings, walls, and furniture
- Mold and mildew growth due to trapped moisture
- Structural damage from long-term water seepage
- Energy inefficiency, as leaks compromise insulation
Waterproofing is not just about sealing cracks. It is about protecting your investment and making sure your skylight lasts for many years.
Common Materials Used in Skylight Waterproofing
Different skylight types require different waterproofing solutions. In Singapore, contractors typically use:
- Silicone Sealants 🟢 Flexible, UV-resistant, and ideal for sealing joints around glass and frames.
- Polyurethane (PU) Sealants 🟢 Strong adhesion, durable, and resistant to weathering.
- Waterproof Membranes 🟢 Applied around the skylight base to create a watertight barrier.
- Acrylic Coatings 🟢 Cost-effective, reflective, and suitable for flat roof skylights.
- EPDM Rubber Flashing 🟢 Excellent for long-term durability and flexibility.
Each material has its pros and cons, but the best contractors in Singapore often combine methods for maximum protection.
