Property across Durham runs to colliery terraces and stone market towns with growing extension and conversion demand — context that genuinely changes what we specify, from glazing coatings to frame colours and fixing details.
You get the same product either way — thermally broken aluminium, self-clean and solar-control glass options, made to the millimetre. The only choice is who fits it: your builder with our documentation, or our own nationwide teams.
Standard sizes below — made to measure quoted same day. Installation available nationwide if you’d rather we fit it.

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.
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.
Send the form and we’ll come back with honest prices — supply-only or installed — with a response within 1 working hour.
