Roof and VELUX Window Installation Across Sussex

Roof windows are an excellent way to bring natural light and ventilation into lofts, extensions, kitchens, stairwells and rooms with limited wall space.

Bespoke Roofing & Renovations installs and replaces roof windows throughout East and West Sussex. We can complete the roofing work, form the opening, install the correct flashing system and make sure the window is properly weatherproofed into the surrounding roof covering.

Professional Roof Window Installation

A roof window must be installed correctly to prevent leaks, heat loss and condensation around the opening.

Our team can assess the roof covering, pitch and internal position before recommending a suitable window and installation method. We work with tiled and slated roofs and can install roof windows as part of a larger roofing project or as a standalone improvement.

Our roof window services include:

• New VELUX window installation

• Replacement of old or damaged roof windows

• Installation into tiled and slated roofs

• Correct flashing kits for the roof covering

• Replacement of defective roof-window flashings

• Installation during full roof replacements

• Roof windows for lofts and extensions

• Insulation around the window opening

• Internal plasterboard finishing where agreed

• Repairs to leaking roof windows

• Removal and replacement of misted or deteriorated units

Installing a New VELUX Window

Installing a new roof window normally involves forming an opening within the existing roof structure.

Depending on the roof and window position, the work may include:

• Carefully removing the surrounding roof tiles or slates

• Forming the required opening

• Trimming and strengthening the roof timbers where necessary

• Installing the roof-window frame

• Fitting the correct underfelt collar and drainage components

• Installing the appropriate flashing kit

• Relaying tiles or slates around the window

• Insulating around the frame

• Completing internal plasterboard and finishing work where included

The exact method will depend on the roof construction, window size and selected product.

Replacement Roof Windows

Older roof windows can become difficult to operate, draughty or prone to condensation. The external flashings and seals can also deteriorate over time.

We can remove an existing roof window and install a suitable replacement, often using the same opening where the size and condition allow.

A replacement may be appropriate where:

• The glazing has misted

• Water is entering around the frame

• The window no longer opens or closes properly

• The timber frame has deteriorated

• The seals have failed

• The window provides poor insulation

• Replacement parts are no longer available

• The room would benefit from modern glazing and ventilation

Where the leak is caused by failed flashings rather than the window itself, we will explain whether a flashing repair or full replacement is the more practical option.

Roof-Window Flashings

The flashing system forms the weatherproof junction between the window and the roof covering.

Different flashings are required for different materials, including:

• Plain tiles

• Interlocking concrete tiles

• Natural slate

• Fibre-cement slate

• Profiled roof coverings

Using the wrong flashing kit or installing it incorrectly can allow rainwater to track beneath the roof covering.

We install the correct flashing system for the roof type and ensure the surrounding felt, battens, tiles or slates are properly detailed around the opening.

VELUX Windows During a Roof Replacement

A full roof replacement is often the ideal time to install or replace roof windows.

Because the tiles or slates are already being removed, the opening and flashing system can be incorporated into the new breathable membrane and batten installation. This can provide a cleaner finish and reduce the additional labour compared with installing the window after the roof has been completed.

We can include roof windows within quotations for:

• Complete tiled roof replacements

• Natural slate roof replacements

• Loft renovation projects

• Extension roofs

• Garage and outbuilding conversions

• Replacement roof coverings

Choosing the Right Roof Window

The right window will depend on the room, roof pitch and position of the opening.

Options may include:

Centre-Pivot Roof Windows

Centre-pivot windows are a popular and practical choice. They rotate around the centre of the frame and can be suitable where furniture or fittings are positioned beneath the window.

Top-Hung Roof Windows

Top-hung windows open outwards from the top and can provide a more open view. They are often chosen for converted loft rooms where the window is positioned at eye level.

Electric and Solar Roof Windows

Electric and solar-operated windows can be useful where the opening is difficult to reach. Depending on the model, they may include remote operation and rain sensors.

Obscure-Glazed Roof Windows

Privacy glazing may be suitable for bathrooms, shower rooms and properties where the window overlooks neighbouring buildings.

Conservation Roof Windows

Conservation-style roof windows are designed to sit more discreetly within the roof covering. They may be appropriate for period properties, conservation areas and some listed buildings, subject to any required permissions.

Leaking Roof Windows

Water around a roof window does not always mean the window itself has failed.

Possible causes include:

• Damaged or incorrectly installed flashings

• Cracked tiles or slates around the window

• Failed roofing membrane

• Blocked drainage channels

• Poor installation around the window opening

• Condensation rather than external water penetration

• Deteriorated seals

• Defective glazing

• Insufficient insulation around the frame

Our team can inspect the window and surrounding roof area before recommending a repair or replacement.

Planning and Building Requirements

Many straightforward roof-window installations can be completed without a full planning application, but this depends on the property, window position and proposed alterations.

Additional requirements may apply where:

• The property is listed

• The building is within a conservation area

• The window projects significantly above the roof covering

• The installation overlooks neighbouring properties

• Structural roof timbers need to be altered

• The room is being converted into habitable accommodation

Homeowners should obtain any necessary planning, listed-building or building-control approval before work begins. Where required, we can provide details of the proposed roofing work to support an application.
