From Dereham kitchen extensions to full orangery builds, our roof lanterns service covers supply-only delivery and complete installation throughout Norfolk — same product, your choice of who fits it.
Free, no-obligation quotes · response within 1 working hour · supply-only or fully installed
Around Dereham and the wider county, housing stock runs to flint cottages, barn conversions and big-sky rural plots — lanterns suit both contemporary builds and conservation-sensitive conversions. We've specified and supplied for exactly these property types across Norfolk, 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.
Dereham, Great Yarmouth, King's Lynn and Thetford and the rest of Norfolk all sit inside standard coverage: free surveys, free quotes, and a response within 1 working hour.

Most single-lantern installations are completed in a day once the upstand is ready. Larger or multiple-lantern projects typically run one to two days including flashing and internal making good.
Supply-only prices depend on size and glass specification — our online price list covers the standard sizes, and made-to-measure quotes usually come back the same day. Installed prices add the fitting, flashing and making good, and vary with roof access and upstand condition, so we confirm those on a free survey.
A 150mm minimum upstand is the standard requirement. It lifts the lantern clear of standing water on the flat roof and gives the flashing somewhere to dress. If your upstand isn't built yet, we'll supply the exact external kerb dimensions so your builder can form it ready for the lantern.
A correctly installed modern lantern shouldn't leak. Failures almost always trace back to the upstand or flashing rather than the lantern itself, which is why our installation teams dress and seal the junction as part of every fit, and why supply-only orders ship with full fitting instructions.
Yes — installation is available across Dereham and Norfolk, and if you'd rather buy supply-only, kerbside delivery to Dereham is included in our standard service.
