How Much Does a Roof Lantern Cost? Prices Explained


A roof lantern is a superb way to add a lot more natural light to your home or business, but how much does a roof lantern cost, really? In this guide, we’ll take a look at how much you can expect to pay for a roof lantern and the factors that affect the cost.

What Affects the Price of a Roof Lantern?

The final cost of a roof lantern depends on a variety of factors. In this section, we’ll look at some of the most common variables that will change how much you’ll pay.


The type of glass that you choose for your roof lantern can have a substantial impact on the final price. For instance, double or triple glazing your roof lantern requires, as you would expect, two to three times as much glass. If you decide to tint the glass on your roof lantern, this will also affect the price.

Other types of glass, such as self-cleaning glass or acoustic glass, will also add to the cost.

The Size of the Roof Lantern

Roof lanterns are available in a wide range of sizes, and the bigger your roof lantern, the higher the price. Bigger lanterns need more materials and take longer for workers to install.

Optional Extras

If you decide to add any optional extras to your roof lantern, this can also increase the price. For example, you may wish to add an electric opener, if your roof lantern has a vent, to save you the hassle of opening and closing it yourself. 

Labour Costs

If you live or work in a hard-to-reach area, it may cost more to send workers to your property. Similarly, if there are any special requirements or complicating factors, these can also add to labour costs.

How Much Should You Expect to Pay for a Roof Lantern?

Now that we’ve covered the various factors that can impact your final price, it’s time to look at the roof lanterns that we offer, as well as their price ranges. Please note that delivery to certain postcodes will add to the price, and this additional price will not be calculated at checkout. Please also note that our roof lanterns are available in bespoke sizes but this may also increase the price. All prices are correct at the time of writing.

Roof Lantern FAQs 

We understand that when considering purchasing a roof lantern, you’ll have more questions than just ‘how much does a roof lantern cost?’. In this section, we’ll take a look at some other common questions that you might have.

Will I Need Planning Permission for a Roof Light?

Planning permission adds further costs to the equation, and while in some specific cases, one may be required to add a roof lantern, it should not be an issue for homeowners.

What Is the Difference Between a Roof Lantern and a Roof Light?

If you’re shopping around and also considering a roof light, it’s important to know the difference between these two types of windows. A roof light fits at the same height as a roof, while a roof lantern will extend from the roof, adding some height.

Will a Roof Lantern Be Noisy in the Rain?

Memories of camping may make you worry that roof lanterns will be too noisy if it rains, but this is not the case. Thanks to modern glazing technology, sounds from the outside world should be far quieter than was previously possible.

Will I Need Someone to Fit My Roof Lantern?

Some of our roof lantern models come with clip-on features for easy glass fitting, but if you are not a glazer or a roofer, we would recommend that you hire a professional to help you fit a roof lantern.

Great service from the team. Easy to order, good buying guidance and clear install instructions for my builder. Rooflights look absolutely great! The team at TGS couldn't have been more helpful in organising a smaller delivery vehicle to help with restricted access. Highly recommend TGS.

The glass balustrade gives us an amazing view onto the lake outside. So happy we ended up going for the frameless glass balcony from Toughened Glass Systems instead of one with posts

My job is to design the interiors for a lot of houses and a lot of times the hardest part was when the client wanted some really inexpensive rooflights that should look like some contemporary ones as well. That until I found Toughened Glass Systems and started working with them more and more. They have a lot of this kind of stuff at a very decent price, a price for anyone I can say. If you’re looking for cheap skylights for flat roofs or any types of roof lights, they probably have something for you.
