A roof light can completely transform a room. It brings in natural light from above, opens up darker spaces, and creates a sense of height and openness that standard windows simply cannot achieve. Whether you are planning a new extension, refreshing an older property, or looking to brighten a room that feels closed in, a roof light is one of the most effective upgrades you can make.
Before you choose a style and commit to an installation, it helps to understand the basics. Here is what you need to know if you are thinking about adding a roof light to your home.
Roof lights bring natural light exactly where you need it
Wall space is often limited, especially in kitchens, loft conversions, and single storey extensions. A roof light solves this problem by drawing daylight from above, where nothing can block it. This makes a noticeable difference in spaces that feel dim or enclosed.
Homeowners across Surrey, Hampshire and Berkshire often tell us that a roof light changes the way they use their room. By bringing in brighter, more even light, it creates a more inviting atmosphere and reduces the need for artificial lighting during the day. It is one of the simplest ways to make a home feel more spacious and modern.
There are different types of roof lights to choose from
Knowing the difference between the main styles will help you pick the right one.
Designed for modern homes and extensions with flat roofs. They sit neatly within the roof structure for a sleek, unobtrusive look. Many people choose them for kitchens, living spaces, or garden rooms where clean lines and minimalism work well.
Roof lanterns add height, architectural interest, and a dramatic splash of natural light. The raised structure brings light in from multiple angles, making the room feel brighter and more open. They are popular in open plan kitchen diners and large extensions.
Each style has its own benefits and suit different types of properties. What matters most is choosing the one that complements your roof design, your home, and the look you want to achieve.
Roof lights are also designed to keep your home warm and comfortable
A common question from homeowners is whether a roof light will cause heat loss. The answer is no, not when you choose a high quality unit.
Modern roof lights are built with energy efficient glazing, insulated frames, and advanced seals that protect your home from the elements. They help keep heat inside during the winter and prevent overheating during the summer. Many roof lights also include solar control glazing, which reduces heat from direct sunlight while still allowing plenty of natural light through.
This means you get all the benefits of brighter, more inviting rooms without compromising comfort.
Ventilation is an option too
If you want a roof light that opens, choose a vented design. These can be manual or electric, depending on your preference. Opening roof lights are especially useful in kitchens, bathrooms, and loft conversions where fresh air helps control humidity and keep the room comfortable.
Electric options often include rain sensors, remote controls, and smart home compatibility for ease of use.
Planning permission is usually straightforward
Most roof lights fall under permitted development, which means you can add them without applying for planning permission as long as you meet certain guidelines. These typically relate to how far the unit projects above the roof surface and whether your home is listed or in a conservation area.
If you are unsure, we are always happy to check this for you. It is one of the most common questions we help homeowners with when they first start exploring roof light options.
Installation should always be done by professionals
Installing a roof light is a precise job that must be done correctly to ensure weather resistance, insulation, and structural stability. A poorly fitted unit can lead to leaks, condensation, or draughts, so choosing a trusted installer is key.
At Sheerwater Glass, our team has years of experience fitting roof lights in homes of all ages and styles. We take care of everything from the initial design and measurements to the final installation, ensuring your home stays protected and the finish looks seamless.
Safety glass is essential
All roof lights must be fitted with toughened or laminated safety glass. This ensures they can withstand impact, changing temperatures, and regular exposure to the weather. It also provides protection for anyone inside the home.
If you are choosing a walk on roof light for a terrace or balcony, laminated glass is required to support weight safely. We guide you through the right specifications so you have complete confidence in your choice.
Maintenance is simple
Roof lights are designed to be low maintenance. A simple clean with warm soapy water keeps the frames looking fresh, while the glass can be cleaned in the same way you would clean modern windows. If access is difficult, many homeowners choose to use a professional cleaning service once or twice a year for convenience and safety. Our sister brand, Sheerwater Clean can help you with this.
Keeping seals clear and making sure drainage channels remain unobstructed will also help keep your roof light performing at its best.
A roof light can transform your home
Adding a roof light is one of the most effective ways to elevate the look and feel of your living space. It creates brighter rooms, enhances your interior design, and boosts the overall value of your home.
If you are thinking about adding one to your property, our team at Sheerwater Glass can guide you through the options, help you choose the right style, and ensure it is installed with care and precision.
