Whether you want to add ventilation, boost energy efficiency, or create a standout architectural feature, The Rooflight Co has a solution to suit your needs. By knowing the key types, features, and considerations when choosing the perfect flat roof skylight, you’ll ensure you make the right decision for your space!
Flat roof rooflights are a stylish and effective way to bring more natural light into your home, particularly in spaces where traditional windows aren’t an option. Designed specifically for flat or low-pitch roofs, they are installed directly into the roof surface to create bright, airy interiors.
There are several styles available, including fixed flat rooflights, opening roof windows, and flat roof lanterns. Bespoke options offer even more flexibility, allowing you to choose custom shapes, sizes, and finishes that suit your project.
Whether you’re looking to maximise daylight or add an architectural focal point, flat skylights offer both function and beauty.
Flat rooflights and skylights come in a variety of designs to suit different rooms, architectural styles, and lighting needs.
Here are the most popular types:
Fixed flat rooflights are non-opening units designed purely to let natural light flood into a space.
With clean, minimalist lines and frameless finishes, they’re ideal for modern interiors and rooms where ventilation isn’t a priority. Perfect for living rooms, hallways, or stairwells, fixed rooflights offer simplicity and maximum light transmission.
For those wanting both light and ventilation, opening flat rooflights are the ideal solution.
Available in manual or motorised options, these rooflights are designed to let fresh air in while maintaining energy efficiency.
They work particularly well in kitchens, bathrooms, and south-facing rooms that can benefit from airflow during warmer months.
Roof lanterns and pyramid rooflights add a striking architectural element to your home.
These 3D structures protrude from the roofline and create a sense of height and space, making them ideal for large open-plan areas like kitchens or extensions.
Their elevated design maximises daylight from multiple angles and adds visual drama to any room.
The Rooflight Co. offers a curated selection of flat rooflights, each designed with performance, style, and functionality in mind.
The Conservation Plateau Rooflight combines 21st-century performance with a traditional appearance.
Designed in consultation with conservation officers, it’s ideal for heritage properties and listed buildings.
It preserves period charm while meeting modern building standards, making it a great option for sensitive renovations or conservation areas.
A standout feature for more traditional or commercial spaces, the Conservation Pyramid Rooflight offers a multi-sided design that creates depth and light.
Commonly used in entranceways, communal areas, or hallways, it adds architectural interest while maintaining heritage styling and functionality.
The Conservation Lantern Rooflight is designed to enhance large, communal living spaces.
Its protruding, structured design brings in abundant daylight while echoing Victorian-era architecture.
A top choice for flat roof extensions, especially in kitchens or living rooms, it blends heritage charm with spatial transformation.
For projects with unique specifications or creative vision, The Rooflight Co. offers bespoke and made-to-measure flat rooflights.
From custom sizing to one-off colours and finishes, this service ensures the perfect fit for any non-standard requirement.
Whether you’re enhancing a modern build or restoring a historic property, our team helps bring your ideas to life with precision craftsmanship and premium materials.
When planning a flat rooflight installation – whether for a loft conversion, flat roof extension, or an existing roof-it’s important to consider the orientation of your roof and the direction of sunlight into the room. This will help determine how much light the space receives throughout the day and can affect your overall comfort and energy efficiency.
Larger rooflights can dramatically brighten a room, but be mindful of direct sunlight, which can cause overheating in south-facing rooms during summer.
Structural considerations like supporting beams and electrics may also influence what type of rooflight can be installed.
Start by identifying what you want from your rooflight. Are you looking to maximise natural light, improve ventilation, or add an architectural feature? Clarifying your goals will help guide your selection.
The direction your rooflight faces impacts the type and amount of sunlight your room will receive:
North-facing skylights offer steady, indirect light all day – ideal for larger rooflights or a run of lanterns.
South-facing skylights receive strong sunlight and warmth – great for brightening darker rooms but may require solar control.
East-facing skylights benefit from morning light, ideal for kitchens and breakfast areas.
West-facing skylights bring in evening light, perfect for living spaces or dining areas.
The glazing type affects both comfort and energy efficiency. Options like double glazing or triple-ply laminate glass provide excellent insulation, thermal performance, and durability. Consider self-cleaning or tinted glass if your room gets a lot of direct sunlight.
Look for rooflights constructed from robust materials, such as aluminium frames and high-performance glass, to ensure long-lasting performance and weather resistance.
Ease of installation and ongoing maintenance are key. Some rooflights come with self-cleaning coatings, motorised openings, or manual crank options for added convenience.
If you have non-standard dimensions or a specific aesthetic in mind, bespoke or made-to-measure rooflights offer tailored solutions. These allow you to design a rooflight that meets both the visual and functional needs of your project.
Flat roof window glazing options include double glazing, triple ply laminate glass, as well as conservation style windows that are sensitive heritage requirements without compromising on thermal performance.
Our range of rooflights come as standard with high-performance glazing for maximum insulation and quality finish, with any extra features available upon request.
With bespoke glazing options including clouded glass for privacy and BioClean glass for self-cleaning roof windows with minimal maintenance, you can ensure your rooflight design is suited to your room and your needs.
Depending on the size and style of the rooflight, and your own personal preference, you may prefer a flat rooflight that opens.
Opening flat roof windows allow more ventilation and fresh air into a property and can be a good idea for south-facing rooms that have bright sunlight at midday. Allowing a cool breeze to enter your home and improve airflow, opening flat rooflights can usually open in different ways.
Manually opening rooflight design will include a manual hand winder, as opposed to higher, inaccessible flat rooflights that may require a motorised opening mechanism, usually controlled by remote control or a switch.
This feature offers complete flexibility and an impressive feature that’s incredibly easy to use, with no fuss or manual opening required.
Naturally, the larger the rooflight you install, the more natural light you’ll benefit from.
But it is worth making sure that you have considered the positioning of the rooflight and the direction of the sunlight.
Building regulations for skylights consider the amount of heat that can pass through or be lost through a door or window. This is measured as a U-Value, and the maximum U-Value allowed for a property is stipulated in Part L of the Building Regulations Approval Approved Documents. All of our rooflights offer U-Values in line with modern building regulations, that help to retain heat in the winter and keep the heat out in the summer. Learn more about U-Values and the current requirements.
Our range of flat rooflights and conservation rooflights for flat roofs come in a number of standard sizes. Our bespoke rooflight option offers scope for a one-off, unusual size or design, and our made-to-measure service means we can build a flat roof window with unusual measurements, should you require this.
There may be additional features and operating accessories that you may need for your rooflight, such as ironmongery, extension poles or concealed motors.
Wall-mounted switches are provided for rooflights with a motorised blind feature.
The kerb that the flat rooflight sits upon is made weatherproof using the roof material.
Flat roof window flashing makes it possible to install windows on flat roofs while preventing water damage to the roof and property. The rooflight then sits on the weatherproofed kerb, which also features a silicone bead applied just before the rooflight is gently lowered into place.
This silicone sealant helps prevent any leaks from entering the property, as even though the rooflight is designed to fit snugly in the frame, there will still be a joint between the fixtures.
