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.
