Homeowners and builders in Mexborough come to us for flat roof lanterns for a simple reason: honest supply-only prices, made-to-measure fabrication and installation available right across South Yorkshire.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
The South Yorkshire market is defined by stone-built terraces and post-war estates where single-storey extensions and garage conversions drive most lantern installs — and our Mexborough 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 Mexborough alongside Wombwell, Hoyland and Maltby and the rest of South Yorkshire — 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.

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 — we cut in, trim the joists, form the kerb and make good the membrane as part of an installed retrofit. A survey confirms joist direction and any services in the void first.
We do. Mexborough and the surrounding South Yorkshire towns are core territory for both our installation teams and our supply-only delivery routes.
For Mexborough: same-day made-to-measure quotes, standard sizes delivering in around 7–10 working days, and installation slots booked to suit once the survey's done.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
