Around Finchley and the wider county, housing stock runs to Victorian terraces, side-return kitchen extensions and flat-roof rear additions where a roof lantern is the default way to pull daylight deep into the plan. We've specified and supplied for exactly these property types across Greater London, so recommendations come from real local precedent.
Every lantern is thermally broken aluminium as standard, glazed with 28mm argon-filled units, and available with self-clean and solar-control coatings. Supply-only orders include kerb specifications and fitting documentation; installed projects carry our written workmanship guarantee on top of the 10-year product cover.
Finchley, Uxbridge, Twickenham and Sutton and the rest of Greater London all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.

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.
Yes — Finchley is inside our standard Greater London coverage. Our fitting teams survey and install throughout the area, and supply-only deliveries run to Finchley on dedicated glass transport.
