Skylight Maintenance: A Seasonal Guide for Kiwi Homeowners

In Aotearoa, our four distinct seasons each bring their own challenges for skylight maintenance. From the harsh summer sun to winter’s chill, your skylights need attention year-round to keep them in top shape. This guide will walk you through essential maintenance tasks for each season, ensuring your skylights continue to brighten your home efficiently and effectively.

Spring: The Great Kiwi Clean-Up

As the kowhai blooms and the tui returns, it’s time to shake off winter and get your skylights ready for longer, brighter days.

1. Thorough Cleaning:
   • Use a soft brush to remove any debris from the exterior of the skylight.
   • Clean both inside and outside surfaces with a mixture of warm water and mild dish soap.
   • For stubborn marks, a solution of one part white vinegar to ten parts water works wonders.
2. Seal Inspection:
   • Check the seals around your skylight for any cracks or degradation.
   • Look for any signs of water damage on the ceiling around the skylight.
3. Vegetation Control:
   • Trim any overhanging branches that may have grown during the spring growth spurt.
   • Remove leaves and twigs from gutters to prevent water from backing up around your skylight.

Summer: Beat the Heat

Our Kiwi summers can be scorchers, especially in places like Gisborne or Marlborough. Here’s how to keep your skylights (and home) cool:

1. UV Protection Check:
   • If your skylight has UV-protective coating, check for any signs of wear or peeling.
   • Consider adding heat-reducing film if your skylight doesn’t already have UV protection.
2. Ventilation Optimisation:
   • For vented skylights, ensure the mechanism is working smoothly.
   • Clean any screens to maximise airflow.
3. Shade Solutions:
   • If your skylight lets in too much heat, consider installing blinds or shades.
   • For a DIY option, a shade sail installed below the skylight can reduce heat gain.

Autumn: Preparing for the Change

As the leaves turn and the nights draw in, it’s time to get ready for the cooler months:

1. Leaf Guard:
   • Install leaf guards if you haven’t already, especially if you’re in a leafy area like Wellington’s Karori.
   • Regularly remove fallen leaves from around the skylight to prevent water buildup.
2. Weatherstripping Check:
   • Inspect and replace any worn weatherstripping to prevent drafts and water ingress.
3. Condensation Prevention:
   • Check that your home is well-ventilated to reduce condensation as temperatures drop.
   • Consider using a dehumidifier in rooms with skylights if condensation is a persistent issue.

Winter: Weathering the Storm

From the frosty mornings of Queenstown to the wild Wellington winds, winter can be tough on skylights:

1. Snow Load Management:
   • If you’re in a snowy area like the Central Plateau, use a roof rake with a long handle to gently remove snow buildup from around your skylights.
   • Never use salt or ice-melt products on or around skylights.
2. Leak Detection:
   • After heavy rain (we know there’s plenty in NZ winters), check for any signs of leakage around your skylights.
   • Look for water stains on the ceiling or walls near the skylight.
3. Insulation Inspection:
   • Check that the insulation around your skylight is intact and dry.
   • If you notice any cold drafts, it might be time to re-seal or add extra insulation.

Year-Round Tips

1. Professional Inspection:
   • Have a professional inspect your skylights annually, preferably before winter.
2. Prompt Repairs:
   • Address any issues immediately to prevent more significant problems.
3. Safety First:
   • Always use proper safety equipment when accessing your roof. If in doubt, call a professional.
4. Keep Records:
   • Maintain a log of your maintenance activities and any repairs. This can be helpful for warranty purposes and when selling your home.

Regional Considerations

• Coastal Areas (e.g., Napier, Nelson): Pay extra attention to salt buildup and corrosion.
• High Wind Areas (e.g., Wellington): Check fixings and seals more frequently.
• High Rainfall Areas (e.g., West Coast): Ensure drainage channels are always clear.
• Sunny Regions (e.g., Bay of Plenty): Monitor UV coating wear more closely.

By following this seasonal guide, you’ll keep your skylights in prime condition, ensuring they continue to bring natural light and joy into your home for years to come. Remember, a little regular maintenance goes a long way in extending the life of your skylights and maintaining the comfort of your Kiwi abode.
