What do roof lanterns in Hertford involve?
Our roof lanterns service in Hertford covers hipped glass lanterns that lift the ceiling of orangeries and extensions. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Orangery-style extensions with lanterns are popular across the South East, and solar-control glass makes a big difference on south-facing gardens. Typical uses for roof lanterns include orangeries, kitchen-diners and single-storey extensions.
From Hertford to Hoddesdon, Welwyn Garden City and Hatfield, the same survey-first process applies: measure, specify, fix the price, then fit.
Specification options
- Solar-control or self-cleaning glass
- Rectangular, square or bespoke sizes
- LED lighting in the plaster box
- Opening vents with electric control
- Aluminium or uPVC systems
- Adds visual height to a single-storey room
- Double or triple glazed with solar-control options
Before you order: points to check
- Needs a strong, level kerb or upstand
- Plaster-box depth affects how the lantern looks from below
Do you need permission in Hertford?
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. The Future Homes and Buildings Standards, published in March 2026, apply from 24 March 2027 and keep the 2.2 W/m²K limit for rooflights.
See our building regulations guide for U-values, glazing limits and self-certification.

Questions about roof lanterns in Hertford
Aluminium or uPVC?
Aluminium gives slimmer bars and a longer life; uPVC costs less. We fit both.
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.
Roof lantern or flat rooflight?
A lantern adds height and sky from all sides; a flat rooflight is lower-profile and cleaner from outside. Our guide compares them in detail.
Do I need to be at home for the survey in Hertford?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Will I need planning permission in Hertford?
In England a rooflight on a house is usually permitted development under Class C if it projects no more than 150 mm beyond the roof slope and sits no higher than the ridge.
