Whether it's a single lantern over a Keswick kitchen or a multi-roof development, our flat roof lanterns service pairs supply-only pricing with nationwide installation — and Cumbria is core territory for both.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The Cumbria market is defined by slate-and-stone cottages and fell-side farmhouses — wind-load ratings and heritage detailing both matter here — and our Keswick 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 Keswick alongside Workington, Whitehaven and Penrith and the rest of Cumbria — 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.

The lantern doesn't, but the junction detail differs: EPDM wraps the kerb, GRP laminates onto it, felt is torch-dressed. We supply the right drawing for each.
Almost always the junction, not the lantern — short upstands, membrane finished under rather than over the kerb, or missing seals. Build the kerb right and dress the membrane right, and the assembly is dependable for decades.
A timber kerb at least 150mm above the finished roof surface, built to the lantern's external footprint. We issue exact dimensions at order so it's ready before the lantern arrives.
On installed projects, we coordinate it: the roofer dresses the membrane over the kerb, we bed and seal the lantern onto it. Supply-only orders include junction drawings for EPDM, GRP and felt so your roofer details it correctly.
Yes — installation is available across Keswick and Cumbria, and if you'd rather buy supply-only, kerbside delivery to Keswick is included in our standard service.
Standard-size supply-only prices are on the site now; made-to-measure quotes for Keswick usually come back the same working day, and installed projects are priced after a free survey.
