Glass roof extension for homes and businesses in Bangor (Gwynedd)
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.
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.
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.
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.
What's included
- Written guarantee terms and manufacturer documentation

About Bangor (Gwynedd) for this job

- Coast
- Bangor (Gwynedd) is about 2 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 Bangor (Gwynedd) the midwinter sun reaches about 13° above the horizon at noon, with roughly 7.3 hours of daylight, rising to about 60° and 16.7 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 Wales
- In Wales, Approved Document N covers safety glazing: safety glass is needed in and around doors and in low-level glazing where people could walk into it.

Glass Roofs in Bangor (Gwynedd): 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.
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.
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.
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.
