A Guide to Rooflight and Roof Lantern Maintenance
Rooflights and roof lanterns are built to last, but regular maintenance helps them stay clear, efficient, and looking their best. Whether you’ve installed a Stratus Aluminium Roof Lantern, an Infinity Flat Rooflight, or another glazed system from Contech Conservatories, a little care goes a long way.
This guide covers simple maintenance steps to protect your investment and ensure year-round performance.
Cleaning Your Roof Lantern or Rooflight
Keeping glass surfaces clean not only enhances appearance but also improves light transmission.
Tips:
Clean every 3–6 months using a soft sponge, warm water, and a mild glass cleaner.
Avoid abrasive pads or harsh chemicals, which can damage coatings.
Always clean on a cool, cloudy day to prevent streaking.
Rinse thoroughly with clean water and let it air dry.
If you have self-cleaning glass, like the options available on Stratus and Infinity products, you’ll need to clean less often — rainwater naturally helps keep the surface clear.
Checking Seals and Frames
Inspect your rooflight or lantern’s seals, gaskets, and aluminium frames twice a year.
Look for cracks, debris buildup, or signs of wear.
Remove dirt from drainage channels to prevent water pooling.
For aluminium frames, gently wipe with warm soapy water to maintain their protective coating.
This helps prevent leaks and ensures your system remains watertight and energy efficient.
Maintaining Thermal Performance
Over time, dust and debris can affect insulation performance.
Check that vents and trickle slots are free from obstructions.
If you notice condensation, ensure adequate ventilation
Keep blinds and shades clean to reduce trapped heat.
Maintaining these areas ensures your Stratus Lanterns and Infinity Rooflights continue to perform at their best.
Professional Inspections
For trade installers, offering a regular inspection service can build long-term customer trust.Homeowners should have a professional check seals, joints, and glass integrity every few years, particularly after severe weather.
Protecting Finishes
Contech’s aluminium roof systems come with durable powder-coated finishes in white, grey, or custom RAL colours. To keep them pristine:
Avoid pressure washers on seals or joints.
Don’t use acidic or alkaline cleaners.
Gently polish with a microfibre cloth for a long-lasting sheen.
When to Replace
If your rooflight or lantern shows signs of fogging, draughts, or leaks, it may be time for an upgrade. Modern systems like the Stratus Aluminium Lantern or Infinity Flat Rooflight feature advanced glazing and thermal breaks that outperform older units dramatically.
