Let’s dispel some of the myths around lantern roofs that installers won’t always tell you.

Can you have a lantern roof on a pitched roof?

Typically, a lantern roof normally refers to a flat roof with glazed elevated panels in the middle to create a pitched roof shape.

What are the benefits of a lantern roof?

They allow in an abundance of natural light without comprising on your privacy. If you have a flat roof, they are a great way to improve its appearance. Similar to our range of windows, our lantern roofs are energy efficient which will help to keep your heating bills down.

Are lantern roofs cold?

In the past, glazing in conservatory roofs or extensions has had a reputation of being ineffective. They were often abandoned after becoming too hot in the summer and too cold in the winter. However, efficient glazing eradicates this problem meaning that you can use your orangery all year round. With glass that reflects the sun’s rays, you can be sure that it will never become unbearable in the heat.

Thanks to low U-values, modern glass is able to trap heat more efficiently leaving you with a warmer room in the winter and lower heating bills. With the option of a vent and blinds, you can control how much air and light you let in, similar to your windows. Blinds will also allow you to protect furnishings from the sun’s rays.

Can lantern roofs be noisy?

As mentioned before, glazing technology has come on leaps and bounds in the last few years. Effective glazing will decrease noise pollution and allow you to have a comfortable and peaceful living area. This means they are perfect if your garden backs onto a busy road. You can get the same benefits from replacing your windows. 

How much does it cost to fit a lantern roof?

This will really depend on the size you want as well as whether it’s made of aluminium or uPVC. Lantern roofs are generally cheaper than a fully glazed roof and are much quicker and easier to install.

Does a lantern roof need planning permission?

Usually, you do not need planning permission to re-roof your house. This includes adding lantern roofs. Lantern roofs are, in this sense, a permitted development. However, there are certain condition under which a lantern roof project may require planning permission: if the lantern roof projects more than 150mm from the existing roof’s plane; if side-facing windows are not to be obscurely glazed; if an opening is planned to be built under 1.7m from the floor.

Which is the best choice for a lantern roof?

Our lantern roof systems are one of the best around. There is a range of colour options such as pure white (RAL 9010) or anthracite grey (RAL 7016) for a sophisticated finish. Available in both uPVC or aluminium, you can choose one that’s right for your home to match your home’s windows and doors. With unobtrusive sightlines, a lantern roof can be a beautiful addition to your home.

Couldn’t I just get a skylight?

A skylight is a single-window pane installed into a roof. While they still allow in light and air, they aren’t as effective as a lantern roof in filling a room with natural light.

Are lantern roofs a good idea?

Absolutely. With a range of sizes from 1×1.5m to 2 x 4m, there’s one suitable for all homes. As well as filling your new kitchen or living room with light, they can create attractive centerpieces that give your home the wow factor.
