Ridge & pitched glass roofs in Gwynedd: the essentials
Ridge & pitched glass roofs in Gwynedd means dual-pitch glazed roofs for side returns, links and long extensions. Every quote follows a survey of the roof and the room below.
Wales sees a lot of wind-driven rain, particularly in the west, so upstand height and flashing laps matter more than anywhere. Many Welsh homes have older single-storey rear extensions where a glass rooflight brightens a dark kitchen.

Planning and building rules in Wales
In Wales a rooflight on a house is usually permitted development if it stands no more than 15 cm proud of the roof, except on protected land such as conservation areas and National Parks, where permission is needed. A side-facing rooflight within 10.5 m of the boundary must be obscure-glazed, and non-opening unless the opening part is more than 1.7 m above the floor.
In Wales the limiting values are 2.2 W/m²K for a rooflight and 1.4 W/m²K (or WER Band B) for a roof window in an existing house. Wales also has its own overheating rules (Part O) for new homes, in force since November 2022.

How the job runs
- Tell us about the roof. Send the postcode, rough sizes and a photo or two through the form, WhatsApp or the guide-price tool.
- Free survey. For new installations a surveyor measures the opening, checks the roof build-up and talks through glass and options.
- Fixed written quote. You get the product, the work and the price in writing. Nothing is ordered or paid for until you agree.
- Fitting and handover. We fit, seal and make good, then hand over product data, warranties and any certificate paperwork.

Common questions
Can it have opening vents?
Yes, top-hung vents with electric actuators are common, often with a rain sensor.
Can it be partly solid?
Yes — part-glazed, part-insulated roofs balance light and heat.
How long does a ridge roof take to fit?
Typically two to four days once the walls and supports are ready, depending on length and access.
Is a glass roof too hot for a kitchen?
Without care, it can be. Solar-control glass, an opening vent at the top and a blind make a south-facing glass roof comfortable.
Do I need to be at home for the survey in Gwynedd?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
