Skylight roof windows are a great option to bring daylight into your home. Not only do they improve the space, but they also provide fresh air and improve energy efficiency. Whether you’re building a new home or renovating, skylights are an excellent way to brighten up your property.
What Are Skylights and Roof Windows?
Skylights and roof windows are openings in the roof that are designed to bring light and air into an indoor space. However, skylights and roof windows are not the same – they do have a few different designs, purposes, and functions.
Skylight vs. Rooflight
The terms ‘skylight’ and ‘rooflight’ are often used interchangeably, but there are some nuances.
Skylights are typically fixed windows set into the roof to let in natural light. They can be made from glass or acrylic and are usually framed with metal or PVC. Skylights are used to maximise natural light – often in kitchens, bathrooms, or hallways.
Roof windows are similar but are more like regular windows (except they’re installed on slanted roofs). Roof windows are usually hinged, so you can open them for ventilation, either manually or electronically.
Why Are Skylights Important?
All houses need windows to allow for natural light and fresh air to enter the home – skylights offer the same benefits in hard-to-reach spaces (like hallways, high ceilings, and attics). Find out why skylights are important.
Natural Light
Homeowners largely install skylights to bring more natural light into their homes. Natural light is beneficial to the inhabitants’ health and the home’s aesthetics. It can make a room feel more spacious and reduce the need for artificial lighting during the day, which saves money on energy bills.
Natural light has also been shown to have positive effects on mental health. Exposure to sunlight helps regulate your circadian rhythm, boosting your mood and improving sleep.
Maximum Ventilation
If you can open your skylights, either manually or with an electric motor, the ventilation is good for allowing hot air to escape. This is especially helpful in rooms like kitchens and bathrooms, where excess moisture can build up. By letting warm air rise and escape, skylights can improve the overall airflow and reduce the chances of mould growth.
What Are the Different Types of Skylights and Roof Windows?
- Fixed skylights: The most basic type of skylight, they offer natural light without ventilation. Ideal for hallways, stairwells, or rooms with limited window access.
- Ventilated skylights: These skylights allow for better airflow – perfect for kitchens and bathrooms.
- Tubular skylights: These compact skylights are good in small spaces, like small bathrooms or hallways. They feature a reflective tube that channels light into the room below.
- Manual roof windows: These roof windows are openable by hand, giving you control over ventilation. They’re often installed in pitched roofs.
- Electric roof windows: For those who prefer convenience, electric roof windows are good in high, hard-to-reach places.
- Roof lanterns: Often used in larger spaces like conservatories or kitchens, roof lanterns are raised, glazed structures that allow maximum light to flood into a room.
- Skylight domes: These are often used in commercial buildings. Skylight domes are strong and durable thanks to their rounded shape and are ideal for flat roofs.
How to Install Your Skylight
Installing a skylight is not a DIY job suitable for the faint of heart. It requires proper knowledge of roof structure and insulation to ensure the skylight functions well and doesn’t cause leaks.
- Cut the roof opening carefully to fit the skylight frame. If you’re not confident doing this, it’s always best to hire a professional.
- The skylight frame will need to be securely installed into the roof structure to ensure a snug fit to prevent leaks and ensure the skylight remains secure.
- Proper weatherproofing is essential to prevent water damage. Seal the area around the skylight with flashing and sealant.
Where Is the Best Place to Put a Skylight?
Choosing the right place for your skylight depends on what you’re trying to achieve. Here are some common places to put your skylight:
- Living rooms
- Kitchens
- Bathrooms
- Hallways
- Bedrooms
- Attics
What Style Is Best?
The style of your skylight will depend on your home and its practical requirements. Modern homes often use sleek, minimalistic skylights, while traditional homes may choose more decorative options, like roof lanterns.
Choosing Your Skylight Size
Choosing the right size for your skylight is essential to maximise the benefits of natural light and ventilation. Generally, the bigger the skylight, the more light it will bring in. However, it’s important not to go overboard, as an oversized skylight can cause overheating in the summer or heat transfer in the winter – both of which can increase your bills.
A good rule of thumb is to aim for a skylight that makes up about 5-10% of the floor area of the room you’re adding it to. Consider your needs and the position of the skylight before choosing a size.
How to Maintain Skylights and Roof Windows
Skylights are generally low-maintenance, but they still need some TLC every now and then to ensure they live a long life. Here are some simple maintenance tips:
- Clean the glass: Over time, dirt and grime can build up – clean with a non-abrasive cleaner and a soft cloth to keep it sparkling. Trim nearby branches or trees to prevent scratches or debris from building up.
- Check for leaks: Regularly inspect the seals to ensure there are no leaks or signs of water damage.
- Test the mechanism: If your skylights and roof windows open, make sure the mechanism works properly. Lubricate hinges and moving parts to prevent rusting.
- Inspect flashing and seals: Periodically check the flashing and seals to make sure they’re intact. Damaged flashing can cause leaks, so replace it if needed.
How Much Do Skylights Cost?
The cost of a skylight depends on several factors, including the type of skylight, the material, the size, and the complexity of the product and installation – for instance, Velux skylights cost anywhere from $600.
Basic fixed skylights: $300-500
Ventilated skylights: $500-1,000
Electric roof windows: $1,500-3,000
Roof lanterns: $2,000-6,000
Final Thoughts on Skylights
Skylights are a great way to enhance your home’s natural light, ventilation, and energy efficiency. They bring plenty of benefits, from improved mood and reduced energy bills to increased ventilation and a brighter living space.
FAQs
What Is a Common Problem With Skylights?
Leaks are one of the most common issues, often caused by corrosion, poor installation or worn-out seals. Proper installation, as well as regular maintenance and inspections, can help prevent this problem.
