About glass roof extension in Bedford
Fixed frameless rooflights sit on a flat roof upstand with the glass edge overhanging the kerb, so from inside you see only sky and plaster. The upstand must be level, insulated and weathered into the roof covering, and the roof needs a fall so water drains off the glass.
In England, Approved Document L sets a limiting U-value of 2.2 W/m²K for rooflights, calculated in the horizontal position. Frameless glass roofs and fixed rooflights are usually specified with low-E double or triple glazed units, and their declared performance should be checked against this before ordering.
Walk-on glass panels are laminated from several layers of toughened or heat-strengthened glass so the panel stays in place even if one layer breaks. The top layer usually carries an anti-slip finish, such as a fritted or etched pattern, and the panel thickness is calculated for the expected loads.
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.

Working in Bedford
- Postcodes covered
- MK40, MK41 and the surrounding area, including Kempston, Ampthill and St Neots
- Coast
- Bedford is well inland, around 90 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Bedford the midwinter sun reaches about 14° above the horizon at noon, with roughly 7.5 hours of daylight, rising to about 61° 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.

Replacing windows and doors with similar ones is usually permitted development for houses in England. Flats, listed buildings and homes in conservation areas or covered by an Article 4 direction can need permission, so check with the council first.
What you can choose
Solar-control coatings
Coatings or fritted patterns that reduce heat gain and glare under overhead glass on sunny elevations.
Glass beams and fins
Laminated glass supporting beams instead of steel, keeping the whole roof transparent where spans and loads allow.
Side-return glass roof
Large glass units spanning from the house wall to the boundary, supported on glass beams or slim steel, for extended kitchens.
Glass Roofs in Bedford: questions
Do I need planning permission for a glass roof extension?
It depends on the extension and the property. Some single-storey extensions on houses fall under permitted development, while others need planning permission. Flats, listed buildings and homes in conservation areas or under Article 4 directions have additional controls. Check with your council or an architect early, before the glass is ordered.
How much does a glass roof cost?
The cost of a glass roof depends on the area of glass, the size of each unit, the glass make-up and coatings, the support beams or framing, the structural design and the access for lifting. Walk-on and very large panes cost more because of their thickness. See the guide prices for typical ranges; the written quote fixes the price.
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 is a glass roof installed?
A glass roof is installed onto supports already built and checked, such as walls, steel beams, glass beams or upstands. The glass units are lifted with a crane, glass robot or vacuum lifters, set onto gaskets or setting blocks, fixed and then weather sealed. Most domestic roofs are installed in a day or two once supports are ready.
