Based in Bromley, our experienced roofing team understands the importance of integrating roof windows correctly with existing roofing materials, ensuring effective weatherproofing and a professional finish.

What We Offer
Professional Roof Window Solutions
Whether you’re adding natural light to a room or upgrading an existing roof window, we provide solutions tailored to your property.
New VELUX Roof Window Installation
Installing a roof window can bring natural daylight into areas of your home that might otherwise feel dark or enclosed. We undertake VELUX roof window installations in suitable pitched roofs, taking account of the window's positioning, roof structure, roofing materials and weatherproofing requirements.
VELUX Roof Window Replacement
Older roof windows can become difficult to operate, develop draughts or show signs of deterioration. We can assess existing roof windows and undertake suitable replacements, helping improve their appearance, operation and thermal performance with appropriately specified modern units.
Roof Windows for Loft Conversions
Roof windows are a popular choice for loft conversions, allowing natural light and ventilation into newly created living spaces. We provide roofing installation work for suitable VELUX windows, ensuring they are correctly integrated with the surrounding roof covering as part of the project.
Roof Windows for Extensions
A roof window can help bring additional daylight into a home extension, particularly where conventional wall windows are limited. We install suitable VELUX roof windows for pitched-roof extensions, helping create brighter spaces while maintaining appropriate roof weatherproofing
Roof Window Flashing & Weatherproofing
Correct flashing is essential to prevent rainwater entering around roof windows. We undertake suitable roof window flashing installation and associated roofing work, ensuring the window is properly integrated with the surrounding tiles or slates.
Roof Window Repairs & Associated Roofing Work
Water penetration around a roof window may be caused by damaged flashing, deteriorating surrounding roofing materials or defects in the window itself. We can assess visible roofing and flashing problems and recommend suitable repairs or replacement work where appropriate.
Why Choose Roof Windows?
More Light. More Comfort.
A well-positioned roof window can make a significant difference to your living space, introducing daylight from above and providing additional ventilation.
More Natural Daylight
Roof windows allow daylight to enter from above, helping brighten rooms that receive limited light through conventional windows.
Improved Ventilation
Opening roof windows can help introduce fresh air and improve ventilation in suitable rooms and roof spaces.
Enhanced Living Spaces
Natural light can make loft conversions, bedrooms and extensions feel brighter, more open and welcoming.
Modern Appearance
VELUX roof windows offer a clean, practical design that can complement traditional and contemporary properties.
Energy Efficiency Options
Modern roof windows offer glazing and insulation options designed to help manage heat loss and improve thermal comfort.
Flexible Window Choices
Different sizes, opening mechanisms and glazing options allow roof windows to be selected for a variety of room and roof requirements.
Make More of Your Space
Transform Your Loft With Natural Light
A loft conversion can provide valuable additional living space, whether you’re creating a bedroom, home office or another room.
However, natural light and ventilation are important considerations when planning how the space will function.
VELUX roof windows can be an effective solution, allowing daylight to enter through the pitched roof without necessarily requiring a dormer extension.
At SCJ Roofing Solutions, we undertake suitable roof window installation work as part of loft conversion roofing projects.
We consider the roof covering, available space, window positioning and weatherproofing details to help achieve a professional installation.
Whether you’re planning a loft conversion or improving an existing converted space, our team can discuss the roofing aspects of your project.
Upgrade Your Roof Windows
Is It Time to Replace Your Roof Window?
An older roof window may still be functioning, but signs of wear, poor insulation or difficulty operating it can make replacement worth considering.
Modern VELUX roof windows offer improved glazing and design options that may help enhance comfort, appearance and ease of use.
Common Signs Your Roof Window May Need Replacing
- Difficulty opening or closing the window
- Draughts around the frame
- Condensation between glazing panes
- Visible deterioration of the window frame
- Damaged or ineffective seals
- Persistent leaks associated with the window
- Poor thermal performance
- An outdated window that no longer meets your requirements
Finding the Right Solution
Roof Windows Designed Around Your Space
VELUX offers a range of roof window options with different sizes, opening mechanisms and glazing specifications.
Choosing a suitable window depends on the room, roof design, accessibility and how you intend to use the space.
Centre-Pivot Roof Windows
Centre-pivot windows open around a central axis and offer a practical solution for many loft rooms, bedrooms and other suitable spaces.
Top-Hung Roof Windows
Top-hung windows open outwards from the top, potentially offering an unobstructed view and convenient ventilation where
Manual & Electric Roof Windows
Manual windows provide straightforward operation, while electric and solar-powered options can be useful for windows positioned out of easy reach.
Energy-Efficient Glazing
VELUX offers different glazing specifications designed to provide varying levels of thermal insulation, noise reduction and solar control.
The most appropriate roof window depends on the roof’s construction, pitch, intended use and installation requirements. Our team can discuss the available options as part of your roofing project.
Making the Right Decision
Does Your Chimney Need Repairing or More Extensive Work?
Not every damaged chimney requires major reconstruction. In many cases, localised repointing, brickwork repairs or lead flashing replacement can address deterioration and improve weather resistance. However, extensive masonry damage, significant movement or structural instability may require more comprehensive investigation and specialist work.
When Chimney Repairs May Be Suitable
- Mortar deterioration is limited to accessible sections.
- Individual bricks require replacement.
- Lead flashing is damaged or displaced.
- The chimney remains structurally sound.
- Weatherproofing defects can be addressed through targeted repairs.
When More Extensive Work May Be Necessary
- Large areas of brickwork have deteriorated.
- Significant cracking or movement is visible.
- The chimney stack appears unstable.
- Repeated repairs have failed to resolve the underlying problem.
- Structural defects are identified during an assessment.
Our team can assess the visible condition of your chimney and explain suitable repair options. Where major structural issues are suspected, specialist assessment may be necessary before deciding on the appropriate work.

This is an amazing roofing company. The quote was fair, the work was of a high standard. Communication between myself and the company was excellent. I was informed when the roofers could not work due to the extreme weather. The roofers and plasterer were polite and very tidy. Half the time I didn't realise that they were even on the roof. Best of all was that the quote was spot on and there were no hidden costs. I will be recommending them to all my friends and family.Posted on Google![]()

Fantastic company- SCJ were efficient and professional from start to finish. Really happy with the new roof on our extension and a really lovely group of lads. Office staff were exceptional and kept us well informed in a friendly and courteous manner. Great job, Team SCJ!Posted on Google![]()
Paul ArmstrongTrustindex verifies that the original source of the review is Google.
We recently had a complete roof replacement carried out by SCJ Roofing Solutions and I honestly couldn’t fault the service from start to finish. Sam came out to quote and was polite, professional and very clear in explaining the scope of works. The job itself was slightly awkward due to the property being on a main road, with scaffolding required to both the front and rear, but the team handled the logistics without any issues. Anna in the office was an absolute superstar — she kept everything organised, communicated clearly throughout and made the whole process run smoothly. The guys on site were always professional, respectful and kept the area clean and tidy each day. Most importantly, the quality of the roofing work was excellent and we are extremely happy with the finished result. I would highly recommend SCJ Roofing Solutions to anyone looking for a reliable and professional roofing company.Posted on Google![]()

I found Sam through the nfrc so I assumed they would be quality and I couldn’t be happier with our new roof. Scj are responsive and fairly priced for the excellent quality work they carry out. I’d recommend scj to anyonePosted on Google![]()

Fantastic experience with Sam who came today to assess a leak coming from the roof. He gently and clearly explained his opinion and identified a simple fix. Highly recommend, I will not hesitate to reach out to SCJ for future roofing needs in the future.Posted on Google![]()
Helen STrustindex verifies that the original source of the review is Google.
I came across SCJ Roofing via Velux while seeking help with my windows. They came out, and I was so impressed as they were polite. helpful and honest. The issue was tricky, but they gave it much thought, including recommending just leaving it. They sent a very well-priced quote that was clearly set out and based on the most cost-effective solution. They never rushed me into a decision, either. In the end, I decided against that specific work; however, when I had a more major and straightforward roofing issue, I called them out. Again, the service was impeccable. The quote was, again, clear, well-priced and based on the most cost-effective way to do the work. I immediately accepted and was not disappointed. Communication was excellent; I was kept updated and felt informed. I was so happy I had used them; the care, communication and consideration taken were fantastic. They gave me lots of great advice and ensured there were no other issues with the roof too. All in all, it was a great experience- I recommend them.Posted on Google![]()

We very recently used Sam and his team at SCJ Roofing to fit a new flat roof and repair a leak in the main roof. From the very first inspection/quotation through to all the work being completed we were very satisfied. I have since referred Sam and his team to family and friends and he has carried out work to a very high standard and all have been happy. Will always highly recommend

Roof Window Advice
Your Questions Answered
VELUX roof windows are specially designed windows installed within suitable roof structures, allowing natural daylight and ventilation into rooms beneath the roof. They are commonly used in loft conversions, bedrooms, home extensions and other living spaces.
Yes. VELUX roof windows can often be installed in suitable existing pitched roofs. The roof’s construction, pitch, available space and structural requirements must be assessed to determine the appropriate installation.
Many domestic roof window installations can fall within permitted development rights, provided the relevant conditions are met. However, restrictions may apply to listed buildings, properties in conservation areas and certain roof alterations. Planning and Building Regulations requirements should be checked for the individual project.
Yes. Many older VELUX windows can be replaced with modern units, sometimes using the existing roof opening. The suitability of a direct replacement depends on the window’s size, model and surrounding roof condition.
Opening roof windows can help introduce fresh air and improve ventilation within a room. Their effectiveness depends on window positioning, size, opening mechanism and the room’s overall ventilation arrangement.
Modern VELUX roof windows are available with energy-efficient glazing and insulation features. Thermal performance depends on the particular window model, glazing specification and quality of installation.
Yes. Roof windows are commonly installed as part of loft conversions to introduce natural light and ventilation. The installation must be appropriate for the roof structure and comply with relevant building requirements.
Yes. Suitable VELUX roof windows can be installed in both tiled and slate roofing systems using appropriate flashing kits and installation methods designed for the specific roof covering.
Water penetration around a roof window may result from damaged flashing, deteriorating seals, defective surrounding roofing materials or installation problems. Condensation can sometimes be mistaken for a leak, so identifying the cause is important before recommending repairs.
Installation time depends on whether the work involves replacing an existing window or creating a new roof opening. A straightforward like-for-like replacement may be completed within a day, while new installations or structural alterations can take longer.
The cost depends on the window’s size, specification, opening mechanism, roof accessibility and installation complexity. Creating a new opening or making structural alterations may increase the cost. SCJ Roofing Solutions can assess the roofing work required and provide a quotation.
