Glass roof extension in Kendal
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.
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.
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.
A structural glass roof replaces most or all of a roof with large glass units carried on glass beams, slim steel or aluminium supports. Side-return extensions often use a single run of glass from the house wall to the boundary, giving a bright kitchen without the ridge and bars of a framed roof lantern.

- Coast
- Kendal sits roughly 10 km from the nearest coastline, close enough that exposure on open or high ground is worth considering. Glass roofs near the coast collect salt film that self-cleaning coatings may not fully remove, so occasional rinsing helps. Exposed sites face higher wind uplift, which affects glass thickness and fixings, and any metal supports need coatings or grades suited to salt air.
- Daylight and sun
- In Kendal the midwinter sun reaches about 12° above the horizon at noon, with roughly 7.0 hours of daylight, rising to about 59° and 17.0 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
- Rural sites may have long or narrow access tracks that limit crane positions and panel sizes, so access is surveyed early. Exposed locations face higher wind and snow loads, and leaves and debris from nearby trees mean gutters need regular clearing.
- 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.

Listed buildings in England need listed building consent for most changes to historic windows or glass, and conservation areas can restrict changes visible from the street. Speak to the council's conservation officer before ordering.
Choosing your glass roofs
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.
Solar-control coatings
Coatings or fritted patterns that reduce heat gain and glare under overhead glass on sunny elevations.
Sliding access rooflight
A glazed hatch that slides or hinges open for access to a roof terrace, with weather seals and secure locking.
Glass Roofs in Kendal: questions
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.
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.
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.
