Installing a skylight window typically takes 6 to 12 hours when a team of two people is working on it. If you’re adding a balcony, the process can take 1 to 2 days.
There are a few factors that can affect the overall timeline for the job. These include preparation (e.g., moving furniture or difficulties accessing the area), the need for reinforcements if the roof isn’t strong enough, any additional work required, adding more than one window, and the size of the window (larger windows may be more difficult to install and take longer).
Types of Roof Skylights
Roof Terrace
This type of skylight is similar to a Velux balcony, but it follows the shape of the room and opens up like a hinged doorway leading to the balcony.
Pros: floods the room with natural light, and provides easy access to the balcony.
Cons: light can be blinding without adequate blinds, lack of privacy, requires a lot of space, and high costs.
Electric Top Hung
These windows are operated by a fixed switch or remote control. They are similar to a top-hung window, but they have electrical controls instead of being controlled with a pole.
Pros: convenient, windows open fully, provides unobstructed views, provides an additional fire escape route.
Cons: could be a safety issue for children, weight of the window is placed on one pivot, light can be blinding without adequate blinds, hard to clean, won’t work during a power cut, vulnerable to strong winds when open.
Balcony
A balcony installation can be complex and takes longer than most other skylight installations. It’s typically made up of fixed frames and pivoted frames and provides a unique, elegant aesthetic.
Pros: allows a lot of light to enter, provides additional space, and beautiful aesthetic.
Cons: space is temporary, very expensive, and requires a lot of space and a secure structure.

Pros: window opens fully, provides an additional escape route, unobstructed views.
Cons: difficult to clean, vulnerable to strong winds when fully open, maybe a safety issue for children, light can be blinding without adequate blinds, weight of the window is placed on one pivot, manual operation.
Centre Pivot
This is a popular model where the pivot is in the center of the frame and allows the window to tilt, providing ventilation through the top and bottom.
Pros: cost-effective option, easy to clean and maintain, provides better security, easy to install. Cons: manual operation, doesn’t open fully, can amplify outdoor noises like rain, the roof can leak if it’s not closed properly, light can be blinding without adequate blinds.
Benefits of Roof Skylights
There are several benefits to installing a skylight in your home. Here are some of the main advantages:
Adds Natural Light
Skylights bring natural light into your home, which can improve your mood and help you perform better. They also let in solar heat, which can help save on heating costs in the winter.
Allows Fresh Air In
Skylights can allow a lot of fresh air into your home, which can improve cross ventilation in stuffy rooms and cool down your living space in the summer, potentially saving on air conditioning or fan costs.
Saves on Energy Costs
The sunlight coming in through your skylights can help heat your home and the extra airflow can help cool it down, both of which can reduce your energy costs.
Adds to Resale Value
Skylights are a visually appealing addition to your home that can add equity and increase the resale value. Many potential buyers will appreciate the energy-saving and attractive features of skylights.
Cost of Removing Roof Skylight
You may need to remove a skylight from your home for various reasons, such as replacing it with a new window, fixing an incorrect installation, or updating an outdated or malfunctioning window. If this is the case, you might be wondering how much it costs to remove a skylight.
The cost of removing and replacing a skylight is usually around £150 to £250 in labor costs. This often includes the cost of hiring a waste removal company to dispose of the old window. If you need to handle the waste removal on your own, it can cost anywhere from £10 to £60 depending on the size of the window.
