VeluxRoof Windows: Your essential buying guide
Start with the roof pitch, the available opening size, the room use and how easily you can reach the window. Then compare the window dimensions, glazing specification, opening mechanism and whether compatible flashing or installation accessories are needed.
Centre-pivot designs are often chosen where easy operation and simple cleaning are priorities, while top-hung styles can suit rooms where you want a more open outward view. The best choice depends on the window position, roof angle and how the room will be used.
Most roof windows require flashing that matches both the window model and the roof covering, such as tiles, slates or other roofing materials. Always check compatibility carefully, as the wrong flashing can make fitting more difficult and may affect weatherproofing.
Double glazing is a common choice for general use, while triple glazing may be considered where insulation, comfort or noise reduction are higher priorities. Compare the stated glazing details, energy performance information and any coating features listed for each product.
If replacing an existing roof window, check the product code or measure the visible frame and structural opening where possible. For a new installation, the opening size, rafter spacing and roof construction all matter, so measurements should be confirmed before ordering.

Roof windows can bring daylight, ventilation and a more finished feel to rooms under a pitched roof. Use ShopSmarty to compare suitable options across key practical details rather than treating every roof window as interchangeable.
Check that the roof window is suitable for your roof pitch and the type of room you are improving. A loft bedroom, bathroom, landing or home office may each need a different balance of ventilation, privacy, light and reachability.
The window size should suit the available roof space and the amount of daylight you want. Larger roof windows can change the feel of a room, but they also need the right structural opening and compatible installation components.
Think about whether the roof window will be within easy reach or positioned higher up the slope. Handle placement, hinge style and the direction of opening can make a noticeable difference in daily use.
If you are comparing roof windows with nearby window options such as top-hung, fixed or roof dome designs, focus on where the product will be installed and how much ventilation you need. These are alternative window choices, not sub-types of this category.
Look closely at the glazing specification, including insulation information, safety glass details and any coatings mentioned in the product listing. These features can affect comfort, heat retention and suitability for different rooms.
Frame material and finish also matter, particularly in moisture-prone spaces. Some roof windows are designed with easy-clean surfaces, ventilation flaps or interior finishes that may better suit bathrooms, kitchens or frequently used loft rooms.
A roof window usually needs the correct flashing kit for the roof covering and installation type. Compare product listings carefully to see whether flashing is included, optional or sold separately.
You may also need underfelt collars, insulation collars, blinds or control accessories depending on the installation. Checking these at the comparison stage helps you understand the full set of components required for the job.
