Roof York provides professional VELUX Roof Window Installation throughout York and surrounding areas. Whether you are replacing an old rooflight, adding natural light to a loft, upgrading a bedroom or incorporating roof windows into an extension, we can advise on the appropriate window, flashing system and installation detail for the roof.
Bring daylight, ventilation and usable space into rooms beneath the roof.
Our VELUX Roof Window Installation service covers new installations and replacement roof windows on tiled, slated and suitable flat roofs throughout York.
The correct roof window depends on more than the width of the opening. Roof pitch, roof covering, internal room use, structural arrangement, desired opening method and the required flashing system all influence the correct specification.
VELUX produces different roof-window and flashing systems for different roof types and pitches. Standard pitched-roof installations commonly use proprietary flashing kits designed for the particular roofing material, while dedicated low-pitch and flat-roof products are available for other applications.

Roof York can assess the existing roof, advise on the appropriate installation approach and provide a clear quotation for the roofing work required.

Centre-pivot, top-hung and other roof-window options selected to suit the room and roof.
Proprietary flashings selected to suit tile, slate and compatible roof coverings.
Roof windows can improve daylight, ventilation and the usability of rooms within the roof.
A successful installation depends upon the correct relationship between the window, roof structure, roof covering, insulation and flashing system.
We consider the roof pitch, covering, structural arrangement and proposed window position before recommending an installation method.
The required VELUX product depends upon room use, size, opening method, roof pitch and whether the installation is into a pitched or flat roof.
Options may include centre-pivot, top-hung, electric, solar-powered, conservation-style and dedicated flat-roof windows, subject to the particular project and current VELUX product range.
VELUX produces dedicated flashing systems for different roofing materials and installation conditions. The correct flashing kit forms the weatherproof junction between the roof window and surrounding roof covering. ([VELUX](https://www.velux.co.uk/professionals/technical-library/flashing-installation-products?utm_source=chatgpt.com))
The roof opening is formed, structural alterations are undertaken where required, the window is installed and the roof covering reinstated around the proprietary flashing system.
Discuss Your VELUX InstallationReplacing an existing roof window is usually different from creating a completely new opening.
A replacement may be comparatively straightforward where the existing structural opening remains suitable. A new VELUX Roof Window Installation may require alteration or strengthening of rafters, changes to insulation and internal finishes, and consideration of Building Regulations or planning requirements.
VELUX roof windows can be incorporated into many tiled pitched roofs using a flashing system appropriate to the particular roof covering and profile.
The surrounding tiles need to be cut and reinstated carefully so that rainwater is directed around the window and back onto the roof covering below.
The flashing specification must also suit the roof pitch and tile profile. VELUX publishes dedicated systems for different roof coverings rather than relying upon one universal flashing detail. ([VELUX](https://www.velux.co.uk/professionals/installers/installation-product-system?utm_source=chatgpt.com))
Slate roofs require a lower-profile flashing arrangement compatible with the surrounding slate covering.
Careful setting out is important because the window position affects how surrounding slate courses, side laps and head details can be reinstated.
On traditional roofs, the appearance of the installation should also be considered so that the roof window sits as comfortably as possible within the existing roofscape.
Not every standard roof window is suitable for every roof pitch.
VELUX produces dedicated low-pitch products for certain applications, including roof windows specifically intended for lower roof slopes. Current VELUX technical literature identifies specialist low-pitch solutions for applications around 10°–20°, while many standard flashing arrangements are designed for higher pitches. ([VELUX](https://www.velux.co.uk/professionals/installers/installation-product-system?utm_source=chatgpt.com))
The actual product and installation method should therefore be selected against the measured roof pitch rather than assumed from appearance.
VELUX also manufactures dedicated flat-roof windows and rooflights for low-slope and flat-roof applications.
These products differ from conventional pitched-roof windows and use dedicated upstand and weathering arrangements. Current VELUX flat-roof products include solutions designed for shallow roof pitches, with specific pitch limits depending upon the product selected. ([VELUX](https://www.velux.co.uk/products/flat-roof-windows?utm_source=chatgpt.com))
They can be particularly effective over kitchens, extensions, stairwells and other rooms where vertical windows provide limited natural light.
Where a roof window is proposed within a sensitive historic setting, a conservation-style product may provide a more discreet appearance.
VELUX produces conservation roof-window ranges intended to sit more sympathetically within traditional roofscapes. Different conservation products have different permitted roof-pitch ranges, so the exact model needs to be checked against the building and roof. ([VELUX](https://www.velux.co.uk/products/roof-windows/conservation-roof-windows?utm_source=chatgpt.com))
The use of a conservation-style roof window does not itself remove the need to consider planning permission or listed building consent.
Some domestic roof-window installations may fall within permitted development rights, but this depends upon the building, location, dimensions and proposed projection from the existing roof slope.
Restrictions can apply in conservation areas and other designated locations, while works affecting the character of a listed building may require Listed Building Consent. Government guidance also places additional restrictions on roof alterations in designated land. ([GOV.UK](https://www.gov.uk/government/publications/permitted-development-rights-for-householders-technical-guidance/permitted-development-rights-for-householders-technical-guidance?utm_source=chatgpt.com))
Where the property is listed, in a conservation area or otherwise sensitive, planning and heritage requirements should be checked before work begins.
Older roof windows can eventually suffer from deterioration of seals, glazing, timber finishes or external components.
Where the existing opening remains suitable, replacement with a modern equivalent may improve thermal performance, operation and weather resistance without the extent of work required for a completely new opening.
The existing window code and dimensions can often help identify suitable replacement options.
The window itself is only one part of the installation.
Poorly insulated reveals, gaps around the frame or inadequate vapour control can contribute to condensation, cold bridging and localised heat loss.
Where the surrounding roof is insulated, the window opening should be detailed so that the insulation and internal air/vapour-control layers integrate appropriately with the roof-window installation.
The cost of VELUX Roof Window Installation depends upon the window size, model, flashing kit, roof covering, access requirements and whether a new structural opening needs to be formed.
Replacing an existing window within a compatible opening can be considerably simpler than installing a new roof window where rafters, insulation and internal finishes all need alteration.
Electrical or solar operation, internal finishing, blinds, access scaffolding and heritage requirements can also affect the total project cost.
For this reason, we prefer to price from the actual roof and proposed specification rather than publish a universal installation price.
