Whether it's a single lantern over a Johnstone kitchen or a multi-roof development, our kitchen extension roof lanterns service pairs supply-only pricing with nationwide installation — and Renfrewshire is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Renfrewshire market is defined by tenement flats and suburban semis with steady rear-extension demand — and our Johnstone installs reflect that, with specifications matched to the property rather than pulled off a shelf.
Specification doesn't change with postcode: thermally broken frames, 28mm argon-filled glazing, marine-grade powder coating and a 10-year guarantee, whether you buy supply-only for your own builder or book our installation teams.
Our teams cover Johnstone alongside Bridge of Weir, Paisley and Renfrew and the rest of Renfrewshire — surveys are free, quotes carry no obligation, and we aim for a response within 1 working hour.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

A footprint around one-fifth to one-quarter of the room area is the sweet spot. For a common 4m × 6m extension that points to roughly 1500 × 3000 — dramatic light without turning summer lunchtimes tropical.
Solar-control self-clean units — the coating manages summer heat gain and the self-clean layer deals with the film cooking puts on overhead glass. It's our default spec for kitchen projects.
It needs to — ducting routes across the flat-roof void are the most common clash. Send the kitchen plan and we'll position the lantern and kerb clear of the duct run before anything is ordered.
Once the slab is in and dimensions are real. Fabrication then runs while walls go up, and the lantern lands the week your roofer has the kerb ready — no site storage, no programme gap.
Yes — installation is available across Johnstone and Renfrewshire, and if you'd rather buy supply-only, kerbside delivery to Johnstone is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Johnstone 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.
