Build your Rooflight

Roof Maker’s Slimline® Roof Lantern is trademarked for its ultra-slim aluminium frame construction.

Our patented roof lantern system features the slimmest glazing bars on the market blending the profiles into the glass unit seals to give clean and minimalistic lines for maximum light and a frameless effect. Competitor roof lanterns come with bulky and chunky glazing sections that block out light and give a clunky effect, not with Slimline! Our unique and ultra slim rafters enable maximum light to enter the room, with a more contemporary finish; MORE SKY, LESS ROOF we say!

As with all our rooflights the Slimline glass roof lantern sizes are based on internal hole size, so you actually get a larger roof lantern with us, around 20% larger due to competitors using external sizes and not internal hole sizes.

The dynamic architectural feel of a Slimline roof lantern has much more impact than a flat rooflight because the added increase in internal room height gives increased volume to the room interior.

The option of an opening double glazed vent for natural ventilation – makes the Slimline® Roof Lantern for flat roofs a great choice for kitchens, dining areas, living rooms and most flat roof extensions.

Frequently Asked Questions

What sizes do roof lanterns come in?

At Roof Maker, we offer a wide range of sizes for our lantern rooflights, so you can find the perfect fit for your home. Our roof lanterns come in sizes up to 2 metre wide x 4 metre long or 1.6 metre wide x 6 metre long.

Our expert team can help you select the ideal size for your space, taking into account factors such as the size of your room, the amount of natural light you want to let in, and the position of your roof lantern.

What is the difference between a roof lantern and a skylight?

At Roof Maker, we offer both lanterns for flat roofs and skylights, and each has its own unique features and benefits. A roof lantern is a type of glazed roof structure that sits on top of a roof, with a raised frame and multiple sides. A skylight, on the other hand, is a single glazed unit, that is installed directly onto the roof of a building.

Do you need planning permission for roof lanterns?

In most cases, you won’t need planning permission for a roof lantern installation. This means that you can enjoy all the benefits of a stunning, energy-efficient glass roof lantern without having to go through a lengthy planning process.

However, it’s important to keep in mind that planning regulations can vary depending on your location and the specifics of your property.

How long will delivery of your roof lantern take?

Because our roof lanterns are bespoke and made to order, our lead times will vary based on the specification that you choose. However, it may be as quick as 7 – 10 working days. Please talk to our helpful Sales team to discuss lead times for your chosen product.

What's the Ideal Location for Installing a Roof Lantern?

Roof lanterns are best used in areas where maximising natural light and creating a visually open environment are considerations. They’re frequently installed above kitchens or dining rooms, transforming them into bright, pleasant spaces. Our glass roof lanterns for flat roofs are also ideal for extensions, conservatories, or any room that lacks natural light.

What are the key features of Roof Lanterns?

What truly sets our Lantern Rooflights apart is their exceptionally slim glazing bars – the slimmest available on the market. This innovative design artfully blends the profiles into the glass unit seals, creating clean, minimalistic lines.

Can roof lanterns increase the brightness of the room?

Absolutely, glass roof lanterns are specifically designed to significantly enhance the brightness of any room. The large surface area of the lanterns allows for an abundance of daylight to filter through. In addition to their functional benefits, glass roof lanterns add a touch of architectural elegance.
