Glass roof extension in Bromley
Glass roofs need regular cleaning from safe access, never by standing on non-walk-on glass. Silicone joints between panes should be inspected for splits, gutters and outlets kept clear, and any chips or scratches on walk-on panels checked, because the top layer is designed to protect the layers below.
The price of a glass roof or walk-on panel depends on glass size and make-up, the number of laminated layers, coatings, support beams or framing, structural design, lifting equipment and access. Bespoke shapes and very large panels cost more. See the guide prices for typical ranges.
Overhead glass in a glass roof is generally specified with a laminated inner pane. If the inner glass breaks, the interlayer holds the fragments together instead of letting them fall into the room. BS 5516-2 is the British Standard code of practice for sloping and overhead glazing.
Overhead glass collects heat in summer. Solar-control coatings, low-E coatings and fritted patterns reduce heat and glare under south and west-facing roofs, while opening rooflights or vents elsewhere help warm air escape. Self-cleaning outer coatings reduce how often the glass needs washing.
Included as standard
- Lifting, positioning and fixing of every glass unit
- Site survey and structural assessment of supports
- Glass specification with laminated make-up and coatings
- Weather sealing of joints, edges and upstands

- Coast
- Bromley is well inland, around 25 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Bromley the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.6 hours of daylight, rising to about 62° and 16.4 hours in midsummer. Overhead glass admits far more daylight than vertical glazing, especially in summer when the sun is high. South-facing glass roofs usually need solar-control coatings or fritting, while north-facing roofs can use clearer low-E glass to maximise winter light.
- Access and setting
- City glass roofs often need cranes or lifting robots, so road or pavement licences, parking suspensions and access over neighbouring property may be needed. Side returns usually sit on a boundary, so fire performance and neighbour matters should be checked early.
- Rules in England
- Approved Document K requires safety glass in critical locations in England: glazing in doors and in side panels within 300 mm of a door, up to 1500 mm above floor level, and any glazing in walls or partitions up to 800 mm above floor level.

In England, replacing a whole window, roof window or glazed external door is building work. It has to be notified to building control, either by an installer registered with a competent person scheme such as FENSA or Certass, or through a building notice to the council. Replacing only the glass in an existing frame is a repair and is not notifiable.

Glass Roofs in Bromley: questions
What is the difference between a glass roof and a roof lantern?
A glass roof replaces most or all of a roof with large structural glass units on minimal supports, giving a near frameless view of the sky. A roof lantern is a framed, pitched glazed structure that sits on an upstand within a solid flat roof. Glass roofs suit side returns and link extensions; lanterns suit openings in flat roofs.
Does a glass roof need building regulations approval?
Yes. A new glass roof, frameless rooflight or walk-on panel is building work that normally needs approval through building control, covering structure, energy performance and fire performance near a boundary. Highly glazed extensions often need energy calculations to show compliance. The rules differ between England, Wales, Scotland and Northern Ireland, and we explain the route for your project.
Will a glass roof make my kitchen too hot?
A glass roof can make a room warm on sunny days, because overhead glass receives sun for much of the day. Solar-control coatings, fritted patterns, internal blinds and ventilation from opening windows or rooflights help keep temperatures comfortable. The glass is specified at design stage to suit the orientation and how the room is used.
What guarantee comes with a glass roof?
Manufacturer guarantees apply to the glass units, coatings and any framing or fixings, and the terms are confirmed in writing. Supports built by others are covered by their own builder's terms. Guarantee terms for our installation are set out in writing with your quote, so you know what is covered and who is responsible before work begins.
