Lerwick: structural glass roof
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.
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.
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.

- Coast
- Lerwick is about 1 km from the coast or a tidal estuary, so salt air and wind-driven rain are worth planning for. 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 Lerwick the midwinter sun reaches about 6° above the horizon at noon, with roughly 5.5 hours of daylight, rising to about 53° and 18.5 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
- 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 Scotland
- Section 4 (Safety) of the Scottish Technical Handbooks covers glazing that people could collide with, such as glass in and beside doors and low-level glazing, where safety glass is needed.

Glass Roofs in Lerwick: questions
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.
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.
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 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.
