Welcome to our definitive guide to roof window types, including popular styles, sizes, costs and how to make the right choice for your home.
Natural light can do a lot to improve the atmosphere and mood of your home. By flooding the interior with natural light, you can significantly brighten up the atmosphere and at the same time add an extra dimension to the aesthetics of your home. In addition, daylight can also help improve energy efficiency, reduce energy costs and regulate the temperature in your home. Without a doubt, one of the best ways to bring natural light into your home is to use skylights.
Below you will find our definitive guide to the different types of dormers and some tips to help you choose the right option for your home.
What is a skylight?
A skylight, also known as a dormer or dormer window, is an opening in the roof that is covered with a translucent or transparent material such as glass and whose main purpose is to allow natural light into the structure.
Basically, installing a dormer window in a house is similar to installing a new window, except that it sits on the roof instead of in the wall.
Although they are primarily designed to transmit light, skylights can also be used to let in heat and cold. Certain types of skylights can also contribute to ventilation. The skylights also work beautifully and offer breathtaking views of the sky and the house. In general, they contribute to improving the energy efficiency of a house while at the same time increasing its aesthetic value.
Floor mounting on deck Vs Skylight
Skylight posts are classified according to the type of installation. The main difference between the two is that the dormers on the deck are flush with the roof, while the dormers on the deck are slightly above the roof surface and held in place by the edge.
Below we take a closer look at these two types of skylights.
Skylightwith side mount
As mentioned earlier, the edge lamps are held above the roof surface by the curb. A skylight is a frame built to support a skylight. This frame is usually made of wood or aluminium and is lifted above the roof to attach the dormer.
Despite the simplicity of the kerbstone design, it is very effective and has many advantages. They are excellent at preventing leaks.
Compared to the dormers of the terrace, the accent dormers offer greater flexibility in terms of size. There are also many curbs on the market, and the best thing is that they are relatively affordable. They work well in any type of room and are easy to install.
Bridge stall
Patio dormers are more relevant than sidewalk dormers. These dormers have frames that dazzle directly on the roof. With this method and style of installation you do not need a bezel to place your skylight; the skylight itself acts as a bezel.
The frame of a skylight is usually made of galvanized steel or extruded aluminium and is closed in the roof. This process is sometimes referred to as a recessed installation.
Patio dormers are more energy efficient than their kerb side counterparts. They can also be more visually attractive because they fit well into the structure and appear smoother. However, patio areas are a little more difficult to install.
They must also be properly sealed to prevent rainwater and moisture from penetrating. Caulking kits are generally used with deck roof windows to protect your home from leaks.
Skylight dimensions
Skylights are not subject to strict standard sizes, as they can be adapted to any size according to the requirements and specifications of the owner. They are available in different widths, lengths and heights, and their dimensions can also vary depending on the type and construction of the dormer.
Standard skylight dimensions
Rectangular and flat tempered glass dormers are generally 14 to 72 inches or 36 to 183 inches wide, while their length varies from 16 to 96 inches or 41 to 244 inches. The inner and outer dimensions of the measurements are defined, and these dimensions are usually a difference of 2 to 3 inches. Tube colonies generally have a diameter of 36 centimetres and are no larger than 55 centimetres. ‘
Typical glass thickness of dormers
The thickness of the glass used in skylights also varies according to the design and size, but in general: The bigger the skylight, the thicker the glass should be. Typical glass thicknesses used in skylights range from ⅛ inch or 3.2 mm to ¼ inch or 6.35 mm.
How to choose the right size dormer for your house
According to industry standards, a skylight should cover about 5% of the surface area of a room with many windows. On the other hand, if your room has few windows, it should make up at least 15% of the room. This guarantees the energy efficiency of your roof window.
To determine the total area of the room, simply measure the length and width of the floor with a tape measure. Multiply the length of the part by the width, and the result is the total area of the part.
If the room is well lit and has many windows, multiply the total area of the room by 0.05, and if the room has few windows and is generally dark, multiply by 0.15. If the room is between two rooms or is not dark or well-lit, simply use an average value of 0.10 and multiply this by the total area of the room. This gives you the estimated number of square meters or the total area of your skylight.
How to measure the replacement skylight
To make sure you choose the right replacement size for your existing skylight, there are several methods to take measurements based on the type.
First try to identify the mark of the old skylight. Skylights are usually provided with labels on the frame on the inside, the sash on the outside or engraved on the glass, which indicate the brand name. If you know the brand, please contact your supplier and they will find the right device. But even with the information on the nameplate it is important to measure your old skylight to make sure your new skylight fits in the opening.
How do you measure a replacement skylight according to the type?
- For cover windows to , measure the length and width of the outer glass surface from the inner edge of the façade. Measure the length and width of the plasterboard opening and the length and width of the external glass in the housing.
- For – investigations, measure the length and width of the outer casing and make sure you bring the investigation and any roofing material with you. Measure the outside glass and its width from the inner edge of the roof window cladding.
Recommended skylight dimensions according to room type

- For breakfast at the bar or in narrow rooms – 600 mm x 800 mm, 500 mm x 900 mm.
- Large rectangular spaces – 600 mm x 1200 mm
Dormer window costs
The average cost of a dormer with installation is about $1600, with typical prices ranging from $900 to $2500 for labor and materials.
The price of the skylight itself varies by type, style, brand and size. Below you will find some typical prices for roof windows based on different factors:

- 24 W x 72 H – $900 to $2,700.
- 48 W x 48 H – 1,100 to 3,500
Skylight installation Costs
Labor costs for installing a skylight generally start at $500, but can be as high as $4,000, depending on the size of the skylight and the complexity of the project. Other factors such as roofing, accessibility and the structure of your home (roof pitch, ceiling height, existing indoor conditions) can also contribute to price increases.
Unless you are a very skilled handyman, it is best to leave the installation to the professionals. All the work involved in installing a skylight is quite tedious and requires precision. The installation of a dormer window consists of cutting a hole in the roof, installing and flushing the dormer window, building a diver from the dormer window to the inner ceiling and painting the entire ceiling under the dormer window. In addition, seals are required.
Ventilated or remotely controlled skylights require electrical operation. These are additional costs that must be taken into account in your total budget. Electricians generally charge between $75 and $300 for this type of work.
Replacement price of skylight
The cost of repairing and replacing skylights varies and largely depends on the extent of the damage. Here are some typical prices for each type of work:
- Dormers Repair Costs – On average, the cost of repairing dormers is about $750, but prices can be as high as $1,150, depending on the extent of the damage. Repairs usually include repairing broken parts, inspecting bores, mechanisms, seals and covers, thoroughly repairing corroded parts and repairing leaks.
- Dormer dormer replacement costs – Replacement of dormers is more expensive and generally between $900 and $2,300. This includes a new skylight as well as waterproofing and installation.
- Glass replacement cost – Glass replacement cost between $300 and $800, including labor. If your skylight has two or three windows, it is at the top of the price range shown.
- Leakage repair costs – Leakage is the most common problem with dormers. Repair usually costs between $300 and $800.
- Roof Motor Replacement Cost – A new solar-powered motor can cost up to $500. Replacing a broken motor on your roof can cost between $100 and $500, but if the damage requires hiring an electrician, expect the cost to increase to between $270 and $1,000.
- Replacement costs for manual mechanisms – Manual roof mechanisms cost less than electrical mechanisms. A new handful would cost about $110, and with the extra labor costs, replacement would cost a total of $200 to $400.
Opening of dormers.
The skylights are available in an operational and a stationary version. Open skylights are usually called ventilation windows because they not only bring light into the room, but also allow air to circulate in the room.
Opening dormers are usually hinged at the top and open a few centimetres. Because they are out of range, manufacturers offer different ways to control them. Here are some types of opening dormers:
- Manually operated skylights–Manually operated skylights are the simplest models available on the market. They open and close manually and do not use a remote control. Manually operated skylights installed in ceilings less than 15 metres high are usually equipped with an extension to make them easily accessible. This type of public skylight is a very economical choice, but requires more effort to open than its motorized and automatic counterparts.
- Motorised skylights – Motorised skylights can be opened and closed by means of a wall switch or a hand-held transmitter. Motorised skylights with additional functions, such as integrated blinds, are usually supplied with a radio remote control and a special wall bracket. They are suitable for high, inaccessible ceilings and skylights that open frequently.
All major skylight manufacturers offer motorized skylights. They are more expensive than the manual options, but they are more convenient and easier to use. The costs of the installation are also slightly higher because some electrical work is required, such as B. laying electrical cables to the dormer.
- Automatic skylights – Automatic skylights are the most expensive. These models are usually equipped with a sensor that automatically closes the skylight if rain or moisture is detected. Advanced models are equipped with heat sensors that automatically open the skylight when the room reaches a certain temperature. You can also program the automatic skylights to work at certain times of the day.

The style of the skylight refers to the shape and placement of the glass used. In general, dormers can be divided into two main groups, (1) the basic or flat roof style and (2) the curved style.
Basic or flat dormers are dormers that do not protrude from the roof. They are flat and follow the slope of the roof. Dormers on flat roofs can be installed on the terrace as well as on the pavement. This type of dormer windows is preferred if you want to maintain the appearance of your house. Compared to curved designs, dormers for flat roofs offer more light.
Curved dormers are the opposite of flat dormers because they protrude above the roof surface. They can be a spectacular architectural feature of a house, but are usually more expensive because more glass needs to be built.
Most popular types of dormers
Dormers can be classified according to material, type of use, type of roof and type of space. Here are some of the most popular types of dormers:
Ventilated skylights or vented skylights
Bedroom with skylights and a bed in front of the window.
In addition to improving the appearance of your home, a ventilated skylight has other practical advantages. Ventilated or ventilated skylights not only provide natural light indoors, but also serve another purpose by providing extra ventilation and allowing air in – hence their name. This type of skylight can be opened and looks essentially like a window, but it is installed on the roof of your house.
They are often installed in rooms most in need of ventilation, such as bathrooms, toilets and kitchens. Ventilation roof windows are functional in these conditions, as they allow excess moisture to escape from the room while ensuring a constant supply of fresh air indoors.
Tubular skylights or solar tunnels
Tube-shaped skylights are a less well known method of bringing light into a room. Also known as tubular skylights orsolar tunnels, tubular skylights are not windows that can be opened. As the name suggests, a light strip consists of a small tubular tube that extends from the top of the roof to the ceiling of the room in which you want to install it.
The tube is generally about 10 to 15 inches in diameter and is covered with a spherical dome at the top. The dome captures the light and then uses optical techniques to send the natural sunlight back to the vessel. The tube is usually made of silver, with a mirror finish, so that the light can be fully transmitted. This highly reflective tube is connected to the internal diffuser.
Due to its compact dimensions, the continuous row is the ideal solution for those who do not have much space on the ceiling for a skylight. You can place it so that it fits in a room where large types of skylights do not fit. Due to its size and shape, it can also be easily integrated into the interior. Despite their small size, dormers are able to bring enough extra natural light into the room. The light strip is suitable for the direct illumination of specific places, spaces and objects such as. B. Living room walls, cupboards, utility room, fireplaces and corridors.
Compared to other types, light tubes are much easier to install. It requires no large opening and is also much quicker to install. Skylight domes, however, have a disadvantage. Unlike its stationary or ventilated counterparts, it offers no visibility. So if you want a skylight for aesthetic reasons or to enjoy the view of the sky, this is not the best option for you.
Dome lights
The dome-shaped skylights are made of durable, flexible plastic that allows sunlight into the room. The skylights’ domes are manufactured in two layers, one for protection and one for thermal insulation. The outer layer is thick and coloured, while the inner layer is thin and made of a transparent material. They are sometimes called dome-shaped acrylic skylights or dome-shaped dormers.
Unlike tubular skylights, which are designed to direct rays to a specific room, the skylights distribute sunlight evenly across the room. Even if it is a small source, it can illuminate an entire room with small amounts of light. Domes are very suitable for building entrances, because they can greatly improve the atmosphere of the space and make it more attractive.
This type of skylight can be used in commercial and residential applications such as homes and lobbies. The domes can also be used as floodlights for objects such as murals, sculptures, plantations, paintings, reflective pools and other objects.
Solar powered skylight or solar powered roof window
Like any other solar-powered object, the solar roof window uses energy directly from the sun’s rays. It works in the same way as a conventional electric skylight. In general, the solar powered skylights are supplied with a small remote control that makes it possible to open and close the skylight. You can even buy a solar powered ventilation lantern.
Solar domes are very popular because they are environmentally friendly and very energy efficient, saving money on bills and avoiding energy consumption problems.
Because they come with a remote control, they are also incredibly easy to use, as you can keep the remote at your fingertips, allowing you to operate the lantern at any time at the touch of a button. It’s also very reliable.
Sun domes cost no more than electric skylights. Given the practical benefits it brings, it is indeed a good choice for investment.
Custom-made skylights
Custom skylights are skylights that are manufactured according to the requirements and specifications of the owner. They are ordered directly from the manufacturer or distributor and are adaptable in different shapes, sizes, designs, styles and dimensions. The final design and specification of the custom skylight design determine the cost of the product and the time needed to complete it. On average it takes about a month to make an adapted skylight.
This type of skylight is ideal if the existing roof of your home does not provide space for an ordinary or standard skylight. Custom roof windows can be pyramidal, triangular, round, square, rectangular – basically anything you want. It can be made of impact-resistant glass and has special functions such as rain and temperature sensors.
The adapted skylights can easily be integrated into the design of a structure to improve its aesthetics and architectural features. They also offer the same advantages as any other type of dormer, such as B. Extra natural light and room ventilation.
Fixed skylights
The most popular type of skylight is the fixed skylight. If you don’t need to improve air circulation in a room, but just want to illuminate it better, a fixed skylight is the ideal choice for you. Unlike ventilated skylights, which provide additional ventilation, fixed skylights only bring natural light into the room. They do not open and are similar to fixed glazing or fixed windows that are fully sealed.
Fixed skylights are usually made of 90% glass and an aluminium frame. Other materials used for the frame are wood and other types of steel. The joints of this type of dormer window are sealed to prevent the ingress of moisture. In some cases a sturdy plastic dome is added to the outside to strengthen it. Fixed skylights are available in many DIY stores and large online retailers.
Fixed skylights are ideal for installation in hard-to-reach places. They are also ideal for dimly lit areas such as stairwells and attics because they provide a considerable amount of light. Fixed skylights are also suitable for high ceilings or cathedrals and can create a spectacular effect in these environments.
Tilt window lighting
The hanging skylight is a kind of ventilated skylight. It differs from conventional ventilated dormers in the way it opens. Hinged windows have an upper hinge that allows them to fold up.
They are also called tiltable skylights.
Pyramid-shaped roof hatch
Pyramidal dormers are, as the name suggests, pyramidal and have four sides. They look a bit like a small roof, made of glass and steel frames, resting on a square hole in the ceiling.
In some designs, pyramid-shaped dormers can have horizontal trusses and purlins. They are available in different heights and slopes, depending on the design and technique of the house, while they can vary in size up to 6 meters wide, depending on needs.
Pyramid-shaped skylights are usually installed at the base of skylights on flat roofs. Theta is generally preferred in large spaces such as lobbies and entrance doors.
Some popular variants of the pyramidal skylights are the multi-sided pyramidal skylight or the polygonal skylight, which generally has 6 or 8 side openings, but also irregular multi-sided openings. Another option is the blackberry lamp, which is very similar to the standard pyramid lamp, but instead of a square opening, it rests on a rectangular opening.
Round skylights
The skylights are round on the inside of the house, but flat on the outside. Round skylights can be installed on the terrace as well as on the pavement.
Multiangular skylights
Polygonal dormers are a kind of flat dormers that have an unusual shape – such as an octagon, hexagon, triangle or special shape. Export domes can have a very dramatic effect on the appearance of a house.
Polygonal arched skylights
Arched polygonal dormers are a kind of polygonal dormer. The base is usually octagonal, hexagonal or another unique shape, while the top is convex.
Roof lanterns or conservatory dormers
Before dormers became popular, they were traditionally used to bring light into a building.
Skylights are generally square in shape and protrude upwards from the roof. All sides are covered with glass.
Barrel box lighting
Standing domed lanterns are a kind of dome-shaped lanterns, but instead of standing up to form a peak, they are crowned with curved glass. The curved glass at each end is supported by a semicircular piece of glass, which in turn forms a kind of barrel.
Arched roofs of block
The quarter circle lanterns are a variant of the barrel-shaped lanterns, but they use quarter circle glass at the end instead of semicircular glass.
This type of dormer is generally preferred for arcades, warehouses, parking lots, shopping centres, medical and educational facilities and industrial complexes.
Bubble light
Bubble-skylights use bubble-shaped glass instead of flat glass. This significantly increases the strength of the flat plastic sheet. Besides increasing strength, it also helps to prevent expansion and contraction. Bubble lamps are also calledPlexiglas bubbles.
Plexiglas skylights are known for their efficiency and cost-effectiveness. They are also very light and therefore very easy to install. This type of skylight is very suitable for installation on a flat roof, because the water can drain off when it rains. Because of their unique shape, they can also capture light from different angles. Make sure every room is well lit. Moreover, their bubble shape also allows more room for manoeuvre.
Bubble skylights have a modern look and are suitable for modern and contemporary homes.
Artificial skylights
Artificial skylights are a new innovation developed by the Italian company Coelux in 2015.
CoeLux® specializes in the production of artificial windows and skylights that simulate the view and feel of natural sunlight and sky light thanks to an optical system based on nanotechnology.
The Coelux artificial lighting technology imitates what happens in real nature by using an energy-efficient LED solar energy source. They mimic natural light from colour to temperature with an artificial light source. In fact, it is the perfect balance between artificial and natural light.
Artificial skylights allow you to enjoy the sun and the sky, even when you are indoors. It helps to improve the atmosphere in the room and make it more pleasant.
Types of dormers

The glaze is the largest part of your skylight. Although you can choose plastic or glass as the material for your skylight, the latter is preferred because of a number of advantages.
The type of glass you choose determines the durability of your roof window. Each type of glass has its own characteristics and can improve the performance of your skylight. Here are some types of glass skylights:
- Plexiglas – , also known as polyglass, Plexiglas is a lightweight material made of acrylic. Roof window glazing is the weakest material and has the highest risk of scratching and damage from debris. The main disadvantage of plexiglass skylights is that they wear out when exposed to UV light. They also discolour and yellow over time, which can disrupt visibility and affect the amount of light passing through your skylight.
- Toughened glass for skylights – Toughened glass is stronger than ordinary glass. It is thermally treated to increase resistance. This also makes it scratch resistant and provides insulation. Once broken, the toughened glass shatters into harmless pieces instead of large shards.
- Laminated glass – Laminated glass is coated with a thin layer of polyvinyl butyral (PVB) or ethylene vinyl acetate (EVA) between two layers of toughened glass. This makes it extremely strong and durable. Most high quality roof windows are fitted with laminated glass, making it the most expensive option on the market.
What you need to know before installing the skylight.

Before installing a dormer in your home, you should assess the existing condition and structure of your home. Here are some important design considerations to help you decide if your house is suitable for a dormer:
- Does the dormer match the style and design of your home? The dormer can be integrated into almost any architectural style, whether traditional, modern or contemporary. You can find many models of dormers that fit into any architectural environment. It can also greatly enhance the aesthetics of an old house, making it a valuable addition.
- What is the type of rafter in your house? Skylights are not suitable for all roofs. As they are installed on the roofline, make sure that the roof structure supports the skylight. You should take into account the type of household in your home to ensure that the skylight matches your home.
The first type of roof construction is the , stud frame roof, which is trussed up with individual trusses four metres apart. This type of roof is more suitable for dormers because they have enough space to cut and place the dormers between the rafters.
Another type of rafter is known as , , which consists of prefabricated rafters or triangular blocks. This solution is less ideal for dormers because the rafters are not designed to be adjusted after installation. Any incision or modification could compromise the structural integrity of the roof.
However, if you want to install a dormer in the rafters, you need to choose the right size. The typical size of a truss is about 24 inches in the middle, which is enough for a small skylight. The skylight must not be wider than 2 feet to take account of the limited space between the trusses. If you want to use a larger roof, you should consult a structural engineer so that he can make the necessary recommendations to adjust the rafters on your roof.
- Is your attic free?Once you have an idea where you want to install a dormer, check your attic for any heating, air conditioning or ventilation equipment, cables or pipes that may be in the way.
- What slope is required for the roof? The slope of the roof is also important when installing dormers on the roof. In general, your skylight should be mounted on a slope of five to fifteen centimetres above your latitude.
Some more Skylight FAQs
- Do I need to install a surround for myskylight? The Chase is by definition a framed tunnel that leads the light from the skylight through the attic to the ceiling under the roof. It’s some kind of drywall tunnel. If your house has a cathedral ceiling, you don’t need a niche to install a skylight.
- What is a set of indicators? The sealing kits are used to ensure that your skylight is watertight. It helps prevent leaks and flooding, which helps prevent the growth of mould in your home. Flasher kits are normally sold separately and
- What is a skylight cover? The cladding of the skylight is a piece of aluminium attached to the outside of the skylight. Their main goal is to add an extra layer of protection, provide weather resistance and provide extra insulation.
- What is low-E coverage? Low E means low emissivity and is a kind of thin coating that is applied to the glass to reflect heat and minimize the infrared and ultraviolet waves that pass through the glass. Because it is microscopically fine, it does not reduce the amount of light passing through the window. Low-E glass can prevent damage caused by exposure to UV rays.
Things to consider when buying skylights.
Dormers come in all kinds, materials and designs. So choosing a skylight can be a real challenge, especially if you have hundreds of options ahead of you. Although aesthetics is one of the most important factors when choosing a skylight, it is not the only thing that counts. There are a number of other aspects that need to be taken into account when making a purchase:
- Function. The first thing to be determined when choosing a skylight is its function. Determine your needs – what do you want from your skylight? Do you need it to let in more natural light? Do you need it for extra ventilation? Do you need it to embellish your home or to increase its aesthetic value?
- Aesthetic value and design – Although skylights are considered a neutral architectural element, their design should complement the overall style of your home. Their design must integrate well with the surrounding architecture to ensure that they add aesthetic value to your home.
- Location and position – The location, position and direction of your skylight is. The main purpose of a skylight is to add light or ventilation to a room, so if you are looking for the location, make sure it is in a dark or light space. Ideally, dormers should be placed in rooms directly under the roof, such as B. a finished attic.
The orientation of your skylight is also an important aspect that needs to be carefully planned. Northern dormers are most ideal because they provide light all year round.
There is also overexposure, and you don’t want that if you choose a higher light position. Find a place that is not too exposed to UV rays.
If one of your main goals when installing a skylight is to add a view of a room, make sure that the space you choose is available. The view from your skylight should be free of talking trees or tall buildings. Tall trees can only be useful if your house is in an area with a very warm climate and needs a little more shade to protect it from the sun.
The location and placement of your skylight also influences various other factors, such as the size of the skylight and the number of skylights needed.
- Size and shape of the room – The size and shape of the room can also influence the choice of skylight. Depending on the recommended and standard dimensions of the dormers, the size of the dormers should be around 5 to 20% of the total area of the room. A larger skylight is needed for a larger space.
The shape of your room, on the other hand, influences the type of skylight you choose and how it is installed. In some areas, additional measures may be required, such as B. extra pipes, etc., for the skylight to function effectively.
- Accessibility – The operation of your skylight affects accessibility and comfort. If you choose a ventilated skylight, you have to decide how you want to operate it – do you need a remote control because it is difficult to reach? Or can you just manage it manually?
- Insulating glass– Traditionally a single insulating glass unit was used in dormers, but thanks to modern innovations it is now possible to choose from different materials with special properties.
Glass is not the only glazing for skylights. In addition to choosing a wooden, vinyl or metal frame, you can also choose glass or plastic for the glazing. The glass glazing is twice as heavy as the plastic glazing and costs five times as much. However, it is a wise investment because it offers many practical advantages, such as impact resistance, less discolouration and high adaptability. You can also apply insulation to prevent UV rays from penetrating through the skylight.
If you want to choose glass for your canopy, be sure to use tempered or laminated glass. This kind of glass doesn’t break in a collision. You can also opt for double glazing, which can be a combination of both. It is the most durable type of skylight glass available on the market.
