Multi-pitched architectural glass roofs designed to sit atop flat roof extensions make roof lanterns a stunning focal point for open-plan kitchens, dining rooms, and orangery-style spaces. Featuring slender glazing bars and steep glass pitches, roof lanterns maximise sky views and internal ceiling height. We install and replace bespoke roof lanterns crafted with thermally efficient aluminium profiles, toughened safety glazing, and specialised weather flashings for complete protection against the elements.
Learn More →Engineered to span wider roof apertures, multi-pane rooflights utilise multiple connected glass panels supported by slim structural glazing bars to cover extensive flat roof areas. This design provides maximum daylight coverage across expansive living areas without sacrificing frame stability or thermal efficiency. We install and replace multi-pane rooflight systems with custom-designed aluminium frameworks, high-specification weather seals, and insulated joining bars.
Learn More →Heavy-duty structural glass construction allows walk-on rooflights to integrate directly into external roof terraces, garden decks, and flat roof walkways without compromising safety. Engineered with thick laminated top panes and non-slip surface treatments, walk-on units deliver daylight to rooms below while supporting foot traffic above. Bowalker installs and replaces walk-on rooflights featuring reinforced structural upstands, flush perimeter frames, and high-load safety glass.
Learn More →Non-opening glass configurations make fixed rooflights the ideal choice for spaces where the primary objective is maximising light intake, sky views, and thermal efficiency without needing active ventilation. The simplified frame structure offers sleek aesthetics and exceptional weather tightness over living rooms, kitchens, and corridors. Our in-house team installs and replaces fixed rooflights using structural upstand frames, tamper-proof security fixings, and durable weather seals.
Learn More →Engineered to combine generous natural lighting with effective room ventilation, opening rooflights feature manual or electric actuators that tilt or lift the frame to allow fresh air circulation. These operable units help regulate indoor temperatures in kitchens and top-floor living areas while maintaining complete weather resistance when closed. Bowalker installs and replaces opening rooflights complete with weather-sealed hinge mechanisms, quiet drive motors, and integrated rain sensors.
Learn More →Installing a rooflight improves natural lighting, increases energy efficiency, reduces costs and noise pollution, supports ventilation, boosts property value and improves the overall appearance of your home. Upgrading to modern rooflights, including options such as fixed rooflights or roof lanterns, with airtight seals and insulated upstands, helps reduce heat loss, improve insulation performance and protect interior spaces from draughts, external noise and weather exposure.
Six key benefits of replacing your rooflight are:
Increases Natural Light
New modern skylights feature slimmer frames and high-clarity glass, allowing more daylight to enter living spaces and brightening kitchens, hallways, loft conversions, and extensions.
Improves Energy Efficiency & Reduces Costs
Advanced thermal breaks and argon-filled double or triple-glazing minimise heat loss, significantly lowering your heating bills and carbon footprint.
Reduces Noise Pollution
High-specification acoustic glazing dampens external noise from rain, traffic and wind, creating a much quieter, more serene indoor atmosphere.
Improves Ventilation
Opening rooflights allow controlled airflow, helping remove excess heat, humidity and condensation from interior spaces.
Boosts Property Value
Well-designed rooflights and skylights enhance your property's architectural appeal and increase its overall market value.
Enhances Aesthetics & Style
Contemporary options, such as roof lanterns and rooflights, introduce a modern architectural feature that improves both interior brightness and exterior design.

Brilliant Service from Leon,Jack and Barry when they fitted my new front door. They were so helpful explaining the new lock and I am delighted with my door. My neighbours have commented on how nice it looks. A big “ thank you “ to the whole team at Bowalker Windows from sales to completion I have been very impressed and would certainly recommend this company to family and friends .
We have had a front door and side panel installed,Team Tim did a great job and were very professional and knowledgeable. Wouldn’t hesitate to recommend the company and this team to any one !
Simon and Brandon fitted our three windows in our garage > studio conversion and were great through the day. Arrived when they said they would, were very polite, respectful and pleasant people. Found answers to questions we didn’t realise about the installation and though we haven’t yet finished the project the windows are a very exciting and big step forward for us. Would recommend this company and this team without hesitation. Thank you!
Had a problem with our door which was installed 3 years ago - Bowalker - Dean - came to site within 24 hours and helped resolved- thank you ! Very pleased with professional and prompt service
Excellent service from a local independent company. Highly recommend.
I had replacement windows installed. Design and advice was good and cost was competitive. Installation was started in a good time to a good standard.
Bowalker have been incredibly helpful and provided me with extremely useful information about the windows and doors at a property I moved into, previously supplied by them. Great customer service, really recommend
Bowalker replaced all of our windows and patio doors in November. They are very efficient and got the job done in the pouring rain but did it quick and professionally. We had a couple of teething issues with the doors after completion and they did not hesitate to come out and rectify the issue. Excellent customer service and a friendly team. Would highly recommend
We had a total of 6 windows fitted at end of June 2025 (2 bathroom(frosted), 1 hallway,1 dining room and two big bay windows complete with 2 window boards). Took 5 days in total as bay windows were load bearing ,the window boards were not in warehouse so took extra time to arrive and fit , the silicone/mastic finish wasn’t great and they cut one end of a window board wrong , but after a telephone call a new team of fitters came out and rectified the mistakes of original fitters that we had noticed , a window pane had got scratched in delivery so they replaced that as well. This was a big job that entailed some mistakes but over time was rectified by bowalker windows by sending out another team of fitters to fix some minor mistakes of original fitters . We went on a recommendation from a work colleague who had used Bowalker windows in the past as were very good. Maybe just improve your fitters mastic silicone skills a bit more but is is an old house of 110 years and nothing is level in this house

No, you do not need planning permission to install a rooflight in the UK if the work falls under permitted development rights. The rooflight must not project more than 150 mm beyond the existing roof slope, and additional restrictions may apply to listed buildings, designated areas and properties with restricted development rights.
Yes, new rooflight installations require Building Regulations approval in the UK, particularly when structural alterations are needed to create a roof opening. The installation must meet applicable requirements for structural stability, thermal performance, glazing and fire safety.
Yes, you can install rooflights in conservation areas or listed buildings, subject to applicable planning restrictions and heritage requirements. Listed building consent may be necessary if the work affects the building’s historic character, while conservation areas may have Article 4 Directions restricting permitted development rights.
Yes, a rooflight can be installed on an existing flat or pitched roof if the structure can support the installation and accommodate a suitable opening. Structural modifications, appropriate waterproofing and compliance with Building Regulations may be necessary before installation.
Yes, properly specified and installed rooflights can withstand heavy rain and strong winds when designed for the building’s location and exposure conditions. Weather-resistant glazing, suitable frames, correctly fitted flashing, and effective drainage help prevent water ingress and wind-related damage.
You can prevent condensation on rooflights by improving ventilation, controlling indoor humidity and installing thermally efficient glazing. Double or triple glazing, insulated upstands, appropriate vapour control and adequate airflow help reduce moisture accumulation on internal glass surfaces.
Rooflights can contribute to heat loss in winter and overheating in summer if they have poor insulation or unsuitable glazing. Energy-efficient double or triple glazing, low U-values, solar-control glass and appropriate shading help regulate indoor temperatures and meet applicable Part L requirements in England.
Rooflight installation takes one to two days for a straightforward residential project, depending on the roof structure, rooflight size and accessibility. Larger installations, structural alterations, waterproofing work and internal finishing may extend the installation time to several days.
Yes, you can replace an existing rooflight without replacing the entire roof if the surrounding structure and roofing materials remain in suitable condition. The replacement must be correctly fitted, weatherproofed and compliant with applicable Building Regulations, including thermal performance requirements.
No, you do not need to be home for the installation as long as we have access to the property and your preferences are communicated in advance. Our fully in-house team of rooflight installers will carry out the work professionally, ensuring security, careful handling and completion according to your specifications.
Bowalker Windows Limited provides a 10-year insurance-backed guarantee on every rooflight installation, ensuring peace of mind and long-lasting performance. Our rooflight installations also comply with FENSA (Reg: 33081), ensuring each rooflight meets professional standards for safety, glazing performance, and structural reliability.
