Whether it's a single lantern over a Caernarfon kitchen or a multi-roof development, our atlas roof lanterns service pairs supply-only pricing with nationwide installation — and Gwynedd is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Gwynedd property here means slate-built terraces and Snowdonia farmhouses — exposure ratings and slate-grey frames are popular. That local context shapes what we recommend in Caernarfon — from glass specification to frame colour — before a single quote is written.
Frames are thermally broken aluminium, glazing is 28mm argon-filled with self-clean and solar options, and everything is made to measure. Buy supply-only with kerbside delivery, or have our fitters handle the lot under a written workmanship guarantee.
From Caernarfon we also serve Porthmadog, Pwllheli and Dolgellau and the wider county — so if you're comparing quotes anywhere in Gwynedd, ours is free, fast and without obligation.
Anything from roughly 750mm × 750mm up past 6 metres in length. Every lantern is fabricated to your exact external kerb dimensions rather than forced to a stock size.
Yes — supply-only Atlas orders ship UK-wide with full fitting documentation, and installed projects are handled end to end by our own teams.
The external ridge sightline is 40mm and the hips match it — to put that in context, some budget systems run double that. From inside the room the bars all but vanish against the sky.
Atlas works from a 20-degree pitch, lower than most competing systems. That keeps the lantern's overall height down, which helps with proportion on single-storey extensions and with permitted-development height limits.
Yes — installation is available across Caernarfon and Gwynedd, and if you'd rather buy supply-only, kerbside delivery to Caernarfon is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Caernarfon usually come back the same working day, and installed projects are priced after a free survey.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
