Roof lanterns in Northwich: what is involved?
We handle roof lanterns across Cheshire, including Northwich. In short: hipped glass lanterns that lift the ceiling of orangeries and extensions. The survey checks structure, weathering and orientation, so the quote reflects your actual roof.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. In Northwich, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
Neighbouring towns include Winsford (7 km) and Warrington (15 km). We offer a survey date when we reply to your enquiry.
What you can choose
- Rectangular, square or bespoke sizes
- Solar-control or self-cleaning glass
- Opening vents with electric control
- Internal and external colours
- Aluminium or uPVC systems
- Slim aluminium bars, more glass
- Double or triple glazed with solar-control options
Things we check at survey
- Plaster-box depth affects how the lantern looks from below
- Some designs project above the roof enough to affect planning on certain houses
Planning, building control and Northwich
Most rooflights on English houses do not need planning permission, provided they keep within 150 mm of the roof surface and below the ridge line. A rooflight on a side-facing slope must be obscure-glazed, and fixed shut unless the opening part is more than 1.7 m above the floor.
For English homes the energy rules ask for rooflights of 2.2 W/m²K or better and roof windows of 1.4 W/m²K (or WER Band B); most modern double glazed units meet both. In an extension, glazing including rooflights is normally limited to 25% of the new floor area plus any windows or doors the extension covers, unless a whole-house calculation shows otherwise.
Read the planning permission guide before you commit to a design.

Common questions
Do they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Do roof lanterns get hot?
They can in summer if clear glass is used on a south-facing roof. Solar-control glass and an opening vent make a big difference.
Is the survey in Northwich free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
