Towns we list in Cumbria
We work right across England, and Cumbria is covered on the same footing as everywhere else. There is no showroom or depot to visit. The survey happens at your property or, for fit-only jobs, from your photos. If your address is remote or reached by ferry, tell us early and we will confirm what arrangement is needed before quoting.

What we do on the day
- Roof membrane checked where it meets the lantern frame
- Internal trims fitted to the ring beam or upstand
- Upstand checked for size, level and square before the kit is opened
- Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
- Following the build order — We assemble lanterns in exactly the sequence the instructions give.
Rules that apply in England
England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.
Common questions in Cumbria
Do you cover Cumbria?
Yes. Fitters travel to addresses in Cumbria and the surrounding districts, including CA and LA postcodes. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Will my new roof lantern leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
Can you replace an old dome without redoing the whole roof?
Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
