How to Maintain Your Skylight in Malaysia’s Humid Climate
Skylights are a beautiful addition to any home, offering natural daylight, improved ventilation, and a modern aesthetic. In Malaysia, where bright sunlight is abundant, a skylight can significantly enhance your living space. However, the country’s tropical climate—with its high humidity, heavy rain, and occasional haze—poses unique challenges for skylight maintenance. Without proper care, issues such as leaks, mould growth, and condensation can arise, potentially shortening the lifespan of your skylight.
This guide will walk you through essential maintenance tips to keep your skylight in top condition despite Malaysia’s humid weather.
1. Regular Cleaning to Prevent Dirt Build-Up
Malaysia’s climate means that skylights are often exposed to dust, pollen, bird droppings, and even soot from nearby traffic or industrial areas. Over time, these particles can obscure light, create stains, and damage protective coatings.
- Frequency: Aim to clean the skylight at least twice a year, and more often if you live near construction sites, busy roads, or coastal areas where salt can accelerate wear.
- Method: Use a soft cloth or sponge with mild, non-abrasive soap and lukewarm water. Avoid harsh chemicals that can damage glass or acrylic surfaces.
- Tip: For high or hard-to-reach skylights, use an extendable cleaning pole or hire a professional cleaning service to ensure safety.
2. Inspect Seals and Flashing
The sealant and flashing around your skylight act as the first defence against water infiltration—especially important during Malaysia’s monsoon seasons.
- Check for Cracks: Over time, exposure to heat and humidity can cause sealants to crack or shrink. Inspect the seals every six months and after heavy rainstorms.
- Repair Promptly: If you notice gaps or deterioration, reseal the area using high-quality, weather-resistant sealant. Ignoring small leaks can lead to costly structural damage.
3. Manage Condensation
High humidity levels in Malaysia can lead to condensation forming on skylight glass, particularly in air-conditioned rooms.
- Improve Ventilation: Ensure the room has adequate airflow. Use ceiling fans or open nearby windows when possible to balance humidity levels.
- Install Double-Glazed Skylights: If condensation is a frequent issue, consider upgrading to double-glazed skylights, which reduce temperature differences and minimise moisture build-up.
- Use a Dehumidifier: In particularly humid months, a dehumidifier can help protect both your skylight and surrounding interior finishes.
4. Keep Surrounding Areas Clear
Skylights are often positioned beneath roof features or near overhanging trees. While greenery provides shade, falling leaves, branches, and debris can cause blockages or scratches.
- Trim Overhanging Branches: This reduces the risk of impact damage and prevents leaves from clogging drainage channels.
- Clear Roof Gutters: Blocked gutters can cause water to pool around the skylight, increasing the risk of leaks.
5. Check for Mould and Mildew
In Malaysia’s damp conditions, mould and mildew can develop around skylights, especially if there is poor ventilation.
- Routine Inspection: Look for black spots, musty smells, or discolouration around the skylight frame and ceiling.
- Cleaning Method: Wipe affected areas with a mild vinegar-water solution or a specialist mould remover. Address the root cause by improving airflow and fixing any leaks promptly.
6. Protect Against UV Damage
While skylights allow natural light to flood in, prolonged UV exposure can cause fading of furniture, flooring, and even weaken skylight materials over time.
- Use UV-Resistant Coatings: Modern skylights often come with built-in UV protection, but if yours is older, consider applying a UV-protective film.
- Install Blinds or Shades: For added control, use retractable skylight blinds to block out intense midday sun while still enjoying natural light in the morning or late afternoon.
7. Professional Annual Inspection
Even if you perform regular maintenance, it’s wise to have your skylight checked by a professional once a year.
- What They Check: Professionals can assess structural integrity, ensure flashing and seals are intact, and spot early signs of wear that might not be visible from the inside.
- Peace of Mind: A professional inspection helps prevent small issues from turning into costly repairs, especially in Malaysia’s weather conditions where minor faults can escalate quickly.
8. Prepare for the Monsoon Season
The heavy rainfall during Malaysia’s monsoon periods can test the durability of your skylight.
- Pre-Monsoon Checklist: Ensure seals and flashing are in good condition, gutters are clear, and no debris is blocking drainage.
- Storm-Proofing: If you live in an area prone to strong winds, consider reinforcing your skylight with additional support brackets or covers.
Final Thoughts
A well-maintained skylight can last for decades, bringing natural beauty and light into your home without the worry of leaks or damage. In Malaysia’s humid and rainy climate, proactive care is key. By cleaning regularly, checking seals, managing condensation, and preparing for seasonal weather changes, you can keep your skylight looking and functioning at its best all year round.
Your skylight isn’t just a window to the sky—it’s an investment in your home’s comfort and aesthetics. Treat it with care, and it will reward you with bright, welcoming light for many years to come.
