Skylights can instantly transform a dark, stuffy room into a bright and airy space. In Malaysia, where natural light is abundant year-round, skylights are becoming increasingly popular in both modern and traditional homes. However, improper installation or poor planning can lead to costly problems such as leaks, heat build-up, and reduced energy efficiency. If you are considering adding a skylight to your property, knowing the common pitfalls can save you time, money, and frustration.
Below are the top mistakes to avoid when installing a skylight in Malaysia’s climate.
1. Choosing the Wrong Skylight Type for Your Space
Not all skylights are created equal. Homeowners sometimes choose a skylight purely based on appearance without considering functionality.
For example:
- Fixed skylights are ideal for areas where ventilation isn’t necessary, such as stairwells or hallways.
- Ventilated skylights work better for kitchens and bathrooms to help reduce humidity and prevent mould growth.
- Tubular skylights are perfect for small spaces like walk-in wardrobes or corridors.
Mistake: Installing a fixed skylight in a high-humidity room can trap moisture, causing condensation and potential damage over time.
Solution: Consult a professional to determine which skylight type best suits your space and lifestyle.
2. Ignoring Malaysia’s Hot and Humid Climate
Malaysia’s tropical climate means intense sunlight, heavy rainfall, and high humidity. A skylight that works well in a cooler country may not be suitable here.
Without proper heat- and UV-resistant glazing, your skylight could make your home uncomfortably warm and cause your furniture or flooring to fade.
Mistake: Using standard glass without Low-E (low emissivity) coating or laminated layers can increase indoor heat gain.
Solution: Choose skylights with double glazing, UV protection, and reflective coatings to reduce heat penetration while allowing natural light.
3. Poor Placement and Orientation
The position of your skylight determines how much light and heat it lets in. In Malaysia, the sun’s path is relatively consistent, but the angle of your roof and the direction your home faces still matter.
Mistake: Placing a skylight where it faces direct midday sun can lead to excessive glare and overheating.
Solution: Work with an installer to position the skylight where it captures soft, diffused light—such as a north- or south-facing slope—while avoiding direct overhead midday exposure.
4. Skipping Professional Installation
DIY skylight installation videos may make the process seem simple, but skylights require precision to prevent water leakage and structural issues. Malaysia’s heavy rainfall makes waterproofing especially important.
Mistake: Attempting to install a skylight without the right flashing, sealing, and waterproofing methods.
Solution: Hire an experienced skylight contractor familiar with local weather conditions and roofing structures. This ensures correct installation and compliance with safety standards.
5. Overlooking Roof Structure Compatibility
Not every roof can accommodate a skylight without modification. In Malaysia, many homes have tile, metal, or concrete roofs, each requiring different installation techniques.
Mistake: Cutting into roof rafters or trusses without proper reinforcement, which can compromise the structural integrity of the roof.
Solution: Have a professional assess your roof structure before installation. In some cases, reinforcing beams or altering the roof framing is necessary to support the skylight.
6. Neglecting Proper Waterproofing
One of the biggest skylight-related complaints in Malaysia is leakage during heavy rain. Poor sealing and flashing installation can cause water to seep in, leading to mould growth and ceiling damage.
Mistake: Using low-quality sealants or relying solely on caulking without proper flashing.
Solution: Invest in high-quality flashing kits specifically designed for your roof type, and ensure they are installed correctly to direct water away from the skylight.
7. Forgetting About Ventilation
In a humid climate, trapped heat and moisture can build up around a skylight, especially in enclosed spaces. Without proper ventilation, this can lead to condensation and even damage the skylight frame.
Mistake: Installing a skylight in a poorly ventilated attic or upper floor without adding vents.
Solution: Use ventilated skylights or incorporate roof vents to improve air circulation and reduce humidity.
8. Not Considering Maintenance Needs
While skylights bring in natural light, they can also accumulate dust, leaves, and water spots, especially during Malaysia’s rainy season.
Mistake: Installing a skylight in a spot that’s difficult to clean or access.
Solution: Choose skylights with easy-clean coatings or tilt-and-clean designs. Consider adding insect screens or rain sensors for automated closing on ventilated models.
9. Underestimating Glare Control
Direct sunlight through a skylight can be beautiful but also harsh, making it difficult to work, read, or watch TV comfortably.
Mistake: Skipping blinds or shades, which can result in excessive glare.
Solution: Install skylight blinds, shades, or tinting to control brightness while still enjoying daylight.
Final Thoughts
A skylight can be a fantastic addition to your Malaysian home, bringing in natural light and creating an open, welcoming atmosphere. However, to truly enjoy its benefits, it’s essential to avoid these common mistakes—such as poor placement, inadequate waterproofing, and ignoring climate factors. With proper planning, professional installation, and the right materials, your skylight can enhance both the beauty and energy efficiency of your home for years to come.
