3 common questions about Solatube skylights answered

We get asked a lot of questions about our Solatube skylights every day, and some of the more common questions we get asked over and over again! So we thought we’d put them together in a blog post for you, so if you’ve had questions you’ve been wanting to ask, see if they are answered below.

1. Can you fit a Solatube skylight through a flat roof?

Absolutely! Solatube skylights don’t require a minimum length to work, so no matter the thickness of your roof it can be easily installed, even if you have a flat roof. We have even installed Solatube skylights in garages and garden sheds to give some examples!

The type of roof you have also isn’t an issue. Regardless of whether it is corrugated, concrete tile, terracotta tile or something else, our range of over 60 roof flashings can be fitted onto almost any roof covering. We ensure that each Solatube is customised to your roof requirements and fitted properly by a Certified Solatube Installer so that we can provide our No Leak and Highest Performance Guarantee.

2. What’s the longest Solatube tube you offer?

If you’re looking to install a Solatube skylight in your home, even the smallest Solatube - the size of a dinner plate, will deliver plenty of sunlight down a 6 metre tube. That’s almost the height of a 2 storey building!

The most common tube length for a Solatube skylight in a residential home is around 1.5m, and it is very rare for residential homes to require more than 4m of tubing. But for peace of mind, even if you needed over 10m that would be doable, even if you start noticing some difference in performance at that length.

3. Can I change from a round to a square diffuser?

Solatube skylights come in both round and square, and each shape has several different diffusers to choose from to suit your home and interiors. These can easily be changed to a different diffuser of the same shape and size if you want to try something new (see the full range here).

Changing between the shapes however is a bit like a toddler’s shape sorter – you simply can’t fit the square diffuser to the round tube and hole, so make sure you have a think about which option you want before installation, and discuss what you would like with your licensee.


To conclude...


If you’re looking for a cost-effective way to brighten up your room, Solatube skylights will deliver sunlight to almost any room in your house, no matter if your roof is flat or if you need short or long tubing. Make sure you choose the Solatube shape that you want, book an installation and enjoy a lighter and brighter room, so that you’re not left in the dark!
