Benefits of Skylight Installation
Why Skylights Installation Is a Best Idea (and How to Do It Right)
Modern homes and offices love the natural light that a skylight brings—but only if it’s working properly. A cracked pane, leaky seal, or mis‑aligned vent can turn a bright, airy space into a drafty, damp, or even dangerous one. Below you’ll find the why’s and how’s of skylight maintenance and repair, plus a quick guide to roofs in Singapore, roof‑leak symptoms, and how to choose a certified roofing contractor.
1. The Benefits of Fixing Skylights
| Benefit | Why It Matters |
|---|---|
| Energy Efficiency | A well‑sealed skylight lets in daylight without the extra heat of the sun, reducing reliance on artificial lighting and cooling systems. |
| Comfort & Well‑Being | Natural light raises mood, improves circadian rhythm, and can even boost productivity. |
| Protect Interior Surfaces | Leaks can stain walls, ceilings, and furnishings. Prompt repair prevents costly remediation. |
| Maintain Property Value | A pristine skylight is a selling point; a damaged one can lower resale value. |
| Prevent Structural Damage | Continuous moisture penetration can weaken framing, leading to rot or mold. |
2. Skylight Repair Ideas (Quick Fixes & DIY Tips)
| Problem | Quick Fix | When to Call a Pro |
|---|---|---|
| Cracked or Broken Glass | Replace the pane with a tempered or laminated replacement (always use proper size). | If the frame is damaged or you’re unsure of the correct glass type. |
| Sealing Issues | Re‑apply roofing‑grade silicone sealant around the perimeter. | Old sealant has lost elasticity or you notice persistent dripping. |
| Shower‑Head‑Style Leakage | Adjust the “screws” that hold the vent valve; sometimes they just need tightening. | The vent is corroded or the seal around the vent is blown away. |
| Excessive Heat or Cold | Install a low‑E (low emissivity) film or upgrade to a double‑pane unit. | Your existing skylight is thin‑pane or has been in service for 10+ years. |
| Water Ingress at the Hatch | Replace the hatch seal or consider a sealed, fixed‑hatch design. | The hatch itself is damaged or missing. |
Pro Tip: Even if you can handle a small repair, schedule a yearly professional inspection. That way you’ll catch hidden cracks, roof‑integrity issues, or aging seals before they become full‑blown leaks.
3. Skylight Types Popular in Singapore
Singapore’s tropical climate (hot, humid, and prone to heavy rain) requires skylights that are highly water‑tight and resistant to UV. Here are the most common options:
| Type | Key Features | Typical Use |
|---|---|---|
| Fixed Skylights | No moving parts, minimal seal points; often 1‑2 m². | Living rooms, roofs with low slant, or areas where ventilation isn’t critical. |
| Ventilated Skylights | Equipped with a vent or a 360° rotating shutter. | Kitchens, bathrooms, or spaces that could benefit from passive airflow. |
| Double‑Pane (Thermal‑Double) Skylights | Two layers of glass with an insulating air gap. | Whole‑home daylighting, energy‑efficient offices. |
| Turbine‑Style Skylights | A rotating, turbine-like vent that automatically opens with wind. | Commercial rooftops, where passive ventilation is a plus. |
| Solar‑Powered Skylights | Integrated photovoltaic cells for self‑charging lights or fans. | Smart homes, eco‑buildings, or corporate sustainability projects. |
Key Takeaway: In Singapore, always opt for low‑E coated, double‑pane skylights for optimal energy performance and moisture control.
4. Dealing With Roof‑Top Leaks
Even with solid skylights, a roof can still be vulnerable. Here’s how to spot and tackle leaks:
| Symptom | Likely Cause | Quick Remedy |
|---|---|---|
| Water stains on ceiling | Roof membrane breach, vent seal failure, cracked flashing. | Inspect roof mem‑brane; replace or patch damaged sections. |
| Mold around skylight | Prolonged moisture penetration. | Clean mold, replace damaged sealant, ensure proper drainage. |
| Standing water in the attic | Poor slope, clogged gutters, or damaged slope drains. | Clear gutters, re‑grade roof slope, install/repair slope drains. |
| Pulsating drafts | Vent seal loosened or broken. | Tighten vent fittings; replace corroded components. |
5. Certified Roofing Contractors in Singapore
If you’re tackling larger projects—roof replacement, extensive skylight upgrades, or structural repairs—work with a certified professional. Here’s what to look for:
| Credential | What It Means |
|---|---|
| BSI (British Standards Institution) “Roofing Contractor” Certificate | Demonstrates competency in roofing products, installation, and safety. |
| Singapore Professional Engineers Board (PEB) Accreditation | Indicates the contractor’s engineers meet national standards. |
| ISO 9001:2015 Quality Management System | Shows a commitment to consistent, high‑quality work. |
| Local Green Building Council (GBI) Membership | Experience with eco‑friendly roofing solutions (ideal for double‑pane or solar skylights). |
| Good Standing with the Building and Construction Authority (BCA) | Verified adherence to regulatory codes. |
Tip: Before hiring, ask for a portfolio of recent projects, verify references, and request a detailed written estimate with a timeline.
6. Roof Water Leakage Fixing – Step‑by‑Step
Locate the Source
- Walk the roof; inspect roof‑deck, flashing, and skylight seams.
- Use a ladder safely and wear proper PPE (gloves, harness).
Assess the Damage
- Is it a cracked membrane, a missing sealant bead, or a warped flashing?
- Note how long the leak has been present; older leaks may have caused internal damage.
Prepare the Area
- Clean the seam or panel area; remove debris, old sealant, or damaged material.
- Allow the surface to dry (especially important in humid climates).
Repair or Replace
- Small Cracks: Use a roof‑grade sealant or patch kit.
- Wider Gaps: Replace the flashing or, if necessary, replace the entire skylight frame.
- Severe Degradation: Replace the roofing membrane or consider a new roof system (e.g., EPDM or TPO).
Seal & Protect
- Re‑apply silicone or polyurethane sealant.
- Use a cold‑curing, waterproof sealant that withstands Singapore’s humidity.
Test
- Simulate rain with a garden hose or wait for actual rain; check for leaks.
- Inspect the interior for any dripping or damp patches.
Document & Monitor
- Keep a repair log (date, material used, notes).
- Schedule a follow‑up inspection in 6–12 months.
Pro Tip: After any major repair, install a small rain gauge or moisture meter under the skylight to detect early re‑leaks.
Quick FAQ
| Question | Answer |
|---|---|
| Can I replace a skylight myself? | For simple glass replacement, yes. For structural or vented units, it’s safest to hire a professional. |
| How often should a skylight be inspected? | Every 2–3 years, or after major storms or significant roof work. |
| What’s the cost of a skylight repair? | Minor sealant fixes can be $200–$400; full replacement might range from $1,000–$5,000 depending on size & type. |
| Do I need a roof‑decker license? | In Singapore, roofing work is regulated. Licensed contractors (BSI‑certified) are required for certain roof sizes. |
Final Thought
