Thinking about adding a skylight to your home or workplace? You’re not alone. Skylights are one of the most popular upgrades for flat roofs, bringing in more daylight, improving comfort, and even helping with energy efficiency. But before you buy, there are always questions—lots of them. To make it easier, here are the 10 most frequently asked questions about skylights and the clear answers you need.
1. What is a skylight?
A skylight is a transparent or translucent dome installed on a flat roof. Its main purpose is to allow natural light to enter your interior spaces. Modern skylights are designed with insulation and durability in mind, making them both practical and stylish.
2. How much does a skylight cost?
The price depends on size, material, and whether it’s fixed or ventilating. As a guideline, you can expect prices to range from €150 to €1,500. Larger, insulated, or electric models cost more, but they also deliver extra comfort and efficiency.
3. What types of skylights exist?
You can choose from:
-
Fixed skylights (non-opening, only for light)
-
Ventilating skylights (manual or electric for airflow)
-
Fire-resistant skylights (special safety use)
They also come in single, double, or triple layers and are made of materials like acrylic or polycarbonate.
4. Can a skylight provide ventilation?
Yes. A ventilating skylight can be opened manually or electrically, allowing fresh air to circulate and improving indoor climate.
5. Are skylights insulated?
Absolutely. Double- or triple-layer skylights, especially those in polycarbonate or glass, are designed to reduce heat loss and prevent condensation.
6. Do I need a permit for a skylight?
Usually, no permit is required, especially for flat roofs or when the skylight isn’t visible from the street. Always check your local building regulations to be sure.
7. Skylight vs. roof window—what’s the difference?
-
Skylight → Designed for flat roofs, often plastic domes.
-
Roof window → Built for pitched/sloped roofs, made of glass.
8. How is a skylight installed?
A professional can typically install a skylight in one day:
-
Cut the opening in the roof.
-
Place the upstand.
-
Mount the skylight dome.
9. Are skylights secure against burglary?
Yes. Security can be improved with reinforced hinges, multi-layer glazing, and optional burglar-resistant grilles.
10. How do I maintain a skylight?
Keep it simple: clean with lukewarm water and a soft cloth 1–2 times per year. Also check seals and hinges annually to keep it in top condition.
Conclusion
Skylights bring natural light, comfort, and energy savings to your home. With the right type and installation, they’re a low-maintenance and secure investment that makes any room brighter and more enjoyable.
