More daylight, more comfort, more value

Installing a roof window is one of the smartest improvements you can make to your home. Research by VELUX shows that a roof window lets in up to 3x more daylight than a facade window of the same size. That means a brighter, healthier living space in your attic or upper floor.

A professionally installed roof window also increases your property value by an average of 5-10%. An investment that pays for itself.

  • Up to 3x more daylight than a standard window
  • Natural ventilation against moisture and mould
  • Increases property value by 5-10%
  • HR++ glazing for optimal insulation
  • Usually no permit required

Which roof window suits your home?

Every roof type and every wish calls for a different solution. I will advise you on the best type for your situation.

Centre-pivot window

The most popular choice. Rotates around a central axis, easy to operate. Ideal for roof pitches from 15 to 90 degrees. Suitable for most attics and bedrooms.

Top-hung window

Rotates around a top axis, so the window opens outward. Provides an unobstructed view and is ideal for high placement in the roof. Excellent for steeper roofs.

Flat roof window

Specially designed for flat or very slightly sloping roofs. With upstand and dome for waterproofing. Lets in maximum light in hard-to-reach places.

Combination window

Multiple roof windows combined side by side or stacked. Creates a large light surface and a panoramic view. Popular in attic renovations.

Electric roof window

Remote operation via remote control or smartphone. With built-in rain sensor that closes the window automatically. Ideal for hard-to-reach windows.

Emergency exit/access window

Opens like a door and provides access to the roof. Perfect for roof terraces or as an emergency exit. Meets escape route requirements for renovations.

Skylight installation on your flat roof

A skylight is the ideal solution for daylight on a flat roof. Whether it is an extension, garage or conservatory: a skylight brings natural light to places where a standard roof window cannot. I install both standard domes and custom-made continuous skylights.

All skylights are installed with an insulated upstand and finished waterproof on your existing roofing. During a flat roof renovation, we can include the skylight straight away, saving you a separate appointment and double costs.

  • Standard domes and custom continuous skylights
  • HR++ glazing for optimal insulation
  • Insulated upstand, waterproof finish
  • Combineer met roof insulation for maximum results

Expertly installed, 100% waterproof

Installing a roof window is precision work. A mistake in the sealing leads to leaks, moisture problems and expensive repairs. That is why I exclusively use manufacturer-specific flashing kits and lead flashings that perfectly match your roofing.

I do not just install the window but also take care of the complete interior finishing: trimming, delivering paint-ready and installing a vapour barrier for optimal insulation. You do not need to arrange anything afterwards.

  • Manufacturer VELUX/Fakro flashing kits
  • Complete interior finishing including trim
  • Vapour barrier for optimal insulation value
  • Clean worksite: I always tidy up afterwards

Maintenance and lifespan of your roof window

A well-installed VELUX or Fakro roof window lasts 20 to 40 years. The key to that lifespan is regular maintenance. Fortunately, it is not complicated: with an annual check you keep your roof window in top condition.

Check the sealing around the window every spring. See if the draught strip is still flexible, whether the glass is clean and undamaged, and whether the ventilation grilles are free of leaves and dirt. For wooden roof windows, it is wise to refresh the lacquer every 3 to 5 years. PVC roof windows do not need this.

Do you notice that your roof window is hard to open, has condensation or lets in draughts? Then it is time for maintenance or replacement. I am happy to visit for a free assessment of your existing roof windows.

  • Annual check: 10 minutes, easy to do yourself
  • Wooden window: refresh lacquer every 3-5 years
  • PVC: maintenance-free, just keep clean
  • Condensation or draughts? Free assessment by us

Energy savings with a new roof window

Old roof windows are often one of the biggest energy leaks in the house. Single glazing, worn seals and poorly installed insulation cause heat to escape in winter and make the attic too warm in summer.

Modern roof windows from VELUX and Fakro come standard with HR++ or triple glazing. The difference is immediately noticeable: lower heating costs, a more comfortable indoor climate and less condensation on cold days. When replacing an old roof window, savings can reach up to 15% on your gas bill, especially if you have the insulation around the window improved at the same time.

  • HR++ or triple glazing: standard on all new roof windows
  • Up to 15% savings on heating costs when replacing
  • External sun screening and shutters available
  • Combine with roof insulation for maximum effect

Everything about roof window installation

Have a question not listed here? Feel free to contact us, I am happy to help.

The cost of installing a roof window ranges from €1,200 to €3,500 including installation. A standard VELUX centre-pivot window (78x98 cm) costs an average of €1,400 including fitting. The price depends on the window type, dimensions and whether roof structure adjustments are needed. I always provide a free custom quote.
I often install a standard roof window within 1 working day, including waterproof finishing and interior trim. For multiple windows or structural adjustments to the rafters, it takes 2 to 3 working days. I always schedule a fixed date with you.
Both brands are excellent. VELUX is the market leader with the widest accessory range (blinds, screens, sun protection) and offers up to 20 years manufacturer warranty. Fakro offers comparable quality, often at a keener price. I advise based on your specific situation: roof type, insulation requirements and budget.
In most cases a roof window is permit-free, provided it is placed at the rear of the property and within the existing roof surface. For listed buildings or protected cityscapes, a permit may be required. I always check this for you and help with the application if needed.
Roof windows can be installed on virtually any pitched roof, with a pitch between 15° and 90°. Installation is standard on tile roofs, slate roofs and bitumen roofs. For flat roofs, I recommend a skylight or a flat-roof window with upstand.
I offer a 10-year warranty on installation and waterproofing. On top of that, the manufacturer warranty from VELUX (up to 20 years) or Fakro (up to 15 years) applies to the product itself. You receive a warranty certificate with all details upon completion.
