Side return glass roof across Stevenage
Glass floors and walk-on rooflights bring daylight into basements, lower floors and rooms beneath terraces. Each panel sits on a continuous, level support with gaskets or setting blocks so the glass never touches metal or masonry directly, and the structure below is checked by an engineer.
A new glass roof or walk-on panel is building work that normally needs building regulations approval through building control, covering structure, energy performance and, close to a boundary, fire performance. Planning permission may also be needed depending on the extension and the property, so check with the council.
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.
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.
Included as standard
- Coordination with engineers or builders where required
- Site survey and structural assessment of supports
- Written guarantee terms and manufacturer documentation

About Stevenage for this job
- Postcodes covered
- SG1, SG2 and the surrounding area, including Hitchin, Letchworth Garden City and Welwyn Garden City
- Coast
- Stevenage is well inland, around 63 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Stevenage the midwinter sun reaches about 15° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 62° and 16.5 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.

Specification choices
Fixed frameless rooflight
A flat glass unit bonded to a minimal edge frame on an upstand, giving an unbroken view of the sky from inside.
Glass beams and fins
Laminated glass supporting beams instead of steel, keeping the whole roof transparent where spans and loads allow.
Solar-control coatings
Coatings or fritted patterns that reduce heat gain and glare under overhead glass on sunny elevations.
Glass Roofs in Stevenage: questions
Can you walk on a glass roof?
Only on glass designed as a walk-on panel. Walk-on glass is laminated from several thick layers with an anti-slip surface and is calculated for foot traffic, often with a sacrificial top layer. Standard glass roofs and rooflights are not designed to be walked on, so cleaning and maintenance must be done from safe access.
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.
How do you stop a glass roof leaking?
A glass roof stays watertight through a fall that lets water run off, weather seals and structural silicone joints between panes, well-detailed flashings at walls and upstands, and clear gutters or outlets. Most leaks start at flashings or blocked drainage rather than the glass. Annual checks of joints and outlets prevent most problems.
Is a glass roof safe if the glass breaks?
A properly specified glass roof is designed so that a broken pane stays in place. The inner pane is laminated, so fragments remain bonded to the interlayer instead of falling into the room. The glass thickness, supports and edge details are designed for the expected loads, including snow, wind and maintenance access.
