How Long Do Tubular Skylights Last?
When you invest in a skylight, you want to know it will last. Tubular skylights like
Solatube have a strong reputation for longevity. Their design is simple, their materials are built to handle outdoor conditions, and they require very little ongoing attention. Here's what you can expect.
Built to Handle Australian Conditions
The rooftop dome on a tubular skylight sits exposed to the elements all year round. In Australia, that means strong UV, summer heat, heavy rain, and in some regions, hail. Solatube domes are made from impact-resistant polycarbonate, which holds up well under these conditions. They don't yellow or crack the way older plastic materials used to — a common complaint with earlier skylight products.
The Tube Itself Is Low Maintenance
Inside the roof cavity, the reflective tube is sealed from
dust, moisture, and insects. Because it's enclosed, it doesn't collect grime the way a traditional glass skylight might. The Spectralight® Infinity lining, which gives the tube its high reflectivity, is also designed to retain its performance over many years without needing to be cleaned or replaced.
The Ceiling Diffuser
The diffuser, which is the fitting you see on your ceiling, is the part most likely to need occasional attention. Dust can settle on it over time. A gentle wipe now and then is usually all that's required. Some diffusers can be removed for cleaning, making the task quite straightforward.
How Long Can You Expect It to Last?
Solatube skylights generally last many years with very little maintenance. The exact lifespan depends on factors like
local weather, the quality of the original installation, and how well the unit is cared for. When installed correctly by a certified professional, these systems are designed to perform reliably for the long term.
The Role of Good Installation
A skylight that is properly installed from the start will always outlast one that isn't. Correct waterproofing around the roof penetration is critical. If moisture finds its way into the roof cavity, it can cause damage over time, not just to the skylight, but to the surrounding structure. This is why professional installation for your
skylight needs matters so much.
What to Watch For Over Time
In general, tubular skylights need very little attention. If you notice a reduction in light output, it may be worth checking whether the diffuser needs a clean or whether anything on the roof has shifted. Most issues, if they occur at all, are minor and straightforward to fix.
