Roof Lantern Installation – Everything You Need to Know

A roof lantern can transform a home. But how? And what are the factors you need to consider before embarking on your roof lantern transformation? This blog aims to find out.

Why Choose a Roof Lantern?

So, why choose a roof lantern?

A roof lantern allows the maximum amount of natural light to enter a room, creating a bright, airy space. The stylish and beautiful design of a roof lantern also adds a stunning focal point.

Most roof lanterns, including those from National Plastics, offer high thermal performance, keeping a room warm in winter and cool in summer for year-round comfort.

Roof lanterns are tailored to each individual home. This made-to-measure approach ensures the roof lantern fits perfectly, increasing energy efficiency and maximising natural light.

Choosing the Right Roof Lantern for Your Home

A roof lantern is an investment, so you need to make sure the one you choose is the most suitable for you and your home. So what are your choices?

There are two main types of roof lantern, aluminium and PVCu, each with their own pros and cons.

PVCu roof lanterns offer a stylish, durable, and cost-effective solution, and are available in a range of colours and designs allowing you to blend your new roof lantern beautifully into your existing home.

Aluminium is exceptionally strong. This strength allows for slimmer frames and more glass, which lets the maximum amount of natural light into your home. Aluminium is also extremely durable and long lasting, and while it is the more expensive option, it will last a lot longer than any alternative. It is also available in more colours than its PVCu counterpart.

Glass Options - Finding the Right Finish

As well as the material, you can also choose the glass you have installed. Here at National Plastics, we offer neutral and blue coloured glass. Each glass finish creates a unique internal aesthetic and ambience so it's important to choose the right one for you.

It is important to remember that the size and style of your new roof lantern may have an impact on its finished appearance. For example, larger roof lanterns may require more supports than a smaller lantern. This will affect the final aesthetic of your new lantern. Smaller roof lanterns, particularly aluminium ones, will require less support, resulting in a more open, airy ceiling.

Planning Your Roof Lantern Installation

As we've mentioned, a roof lantern is an investment. As such you need to ensure you plan correctly to avoid any future issues.

It's imperative the measurements for your new roof lantern are exact. As such, we would always recommend asking a professional for help and guidance to guarantee the most perfect finish for your roof lantern.

In most cases, adding a roof lantern to an existing flat roof falls under permitted development rights. This means you can add a roof lantern without gaining planning permission. However, there are exceptions.

These exceptions include the maximum height of your roof lantern, which should not exceed 4m from the ground, as this is the maximum height permitted for a pitched roof. Also, if you live in a listed building or conservation area, there may be specific guidelines and regulations in place to protect the architectural and aesthetic integrity of the building or area. As such we would always recommend consulting a professional before you start your installation.

Installing Your Roof Lantern - What to Expect

Fitting a roof lantern may seem like a complicated job, but the roof lantern you choose can help make it easier for your chosen installer. For example, roof lanterns from National Plastics have been specifically designed to be easy and safe to install. Unique pre-assembled RidgeLOCK system, clip-on ridge end covers, pre-fitted thermal clips, and easy-fit clip-on capping all combine to make installation a breeze.

Unless you are a professional and have extensive experience of installing roof lanterns, we would always recommend seeking the services of a specialist. This will negate the need for guess work and ensure your installation is finished to the highest quality. Choosing the right installer is also key. Ask to see examples of work and even speak to previous customers who have had a similar installation to you, to ensure you get the right contractor for you.

When your new roof lantern is first installed, it should be fitted with the appropriate insulation and waterproof membrane. This will mean that despite the vastness of glass, your room will remain warm and dry. However, there are ways you can enhance this. For example, specially designed blinds can be fitted to your roof lantern which will not only provide an additional barrier against the cold but also help to keep strong sun light off furniture and fittings.

Maintaining Your Roof Lantern for Long-Term Performance

Keeping your roof lantern clean internally will help to keep it performing and looking it's best. Either using a ladder ensuring your put safety first! or a long-handled brush, clear away cobwebs and dust. This will ensure the maximum amount of light is able to get in. Externally, you should remove any debris which lands on your roof lantern. Cleaning your roof lantern can be tricky. We recommend using a sturdy ladder and having someone at the bottom to hold it steady. Take care not to tread or lean on the lantern. Use warm soapy water and glass cleaner to ensure a perfectly clear finish. On the exterior frame always use a non-abrasive sponge and do not use any harsh or abrasive cleaners.

Common issues faced by owners of a roof lantern are condensation, draughts, and leaks. If your roof lantern has been correctly fitted by a reputable company, you should not experience any draughts or leaks. However, condensation is also caused by internal factors and so can be controlled and prevented by managing moisture levels. You can do this by ensuring your room has proper ventilation, such as extractor fans or opening windows. A dehumidifier can also help to reduce moisture levels.
