Factors Affecting Roof Window Cost

Several factors will impact the cost of your roof window installation. Let’s take a look at some of the key factors:

Window Size and Dimensions: Larger windows naturally cost more. The bigger the window, the more material and installation work are required, pushing up the price.

Material Choices: Roof windows come in a range of materials including uPVC, timber, and aluminium. Aluminium windows tend to be more expensive but offer durability and sleek modern aesthetics. Timber windows provide a natural, high-end look but may come at a premium.

Window Type: Fixed windows are generally cheaper than operable windows. Manual or electric opening windows with ventilation options will cost more.

Roof Pitch: The angle or pitch of your roof can affect the complexity of the installation, which in turn impacts the overall cost. A steeper roof may require more intricate installation, leading to higher costs.

Additional Features: Features such as solar-powered opening, motorised blinds, tinted glass, or soundproofing can add significantly to the price. Solar-powered windows, for instance, can cost up to £1,500 depending on the size and brand.

Brand and Manufacturer: Popular brands like Velux or Fakro may charge a premium for their products due to their reputation for quality and warranty services. However, they are often worth the investment if you’re looking for long-lasting, reliable windows.

Cost Breakdown by Window Type

Let’s dive deeper into the costs of specific roof window types.

Fixed Roof Windows

Fixed roof windows do not open and are typically the least expensive option. These windows are a great choice if you’re looking to maximise natural light and don’t need ventilation. The average fixed roof window cost is £350 – £750, including installation.

Manual Opening Roof Windows

Manual opening windows are designed to be opened manually, usually via a crank or handle. They offer ventilation and are suitable for spaces where airflow is important. These windows typically cost between £500 and £800 with installation included.

Electric Opening Roof Windows

Electric roof windows are equipped with a motor that opens the window at the push of a button. These are ideal for hard-to-reach locations or for those who want a more luxurious option. Expect to pay between £800 and £1,200 for electric windows, depending on size and brand.

Additional Costs to Consider

While the price of the roof window itself is an important factor, there are additional costs associated with installation that homeowners and landlords should be aware of:

Installation Labour Costs: The cost of professional installation typically ranges from £150 to £350. This can increase if your roof has a steep pitch or if additional structural work is needed.
Roof Repairs: If the installation requires any roof repairs, such as reinforcing the structure or replacing roof tiles, expect additional costs.
Blinds and Accessories: Blinds and other window treatments can add between £50 and £200 to the cost, depending on the style and size.

How to Choose the Right Roof Window for Your Home

When selecting a roof window, consider the following:

Purpose: Do you need natural light, ventilation, or both?
Size: What size will work best for your space and roof?
Budget: What is your budget for the window and installation?
Aesthetics: Do you want a sleek modern design or a more traditional look?
Efficiency: Are you looking for energy-efficient windows that help lower your heating bills?
