What do roof lanterns in Hornchurch involve?
Thinking about roof lanterns in Hornchurch? The short answer: hipped glass lanterns that lift the ceiling of orangeries and extensions. The longer answer depends on your roof, which is why we survey before we price.
Mansard and loft conversions are common across London, and roof windows are often set out alongside dormers on the rear slope. Typical uses for roof lanterns include rooms that need height as well as light.
Neighbouring towns include Romford (3 km) and Dagenham (4 km). We offer a survey date when we reply to your enquiry.

Planning, building control and Hornchurch
English householder permitted development (Class C) normally covers rooflights that stand no more than 0.15 m proud of the roof plane and stay below the highest part of the roof. 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.
Read the planning permission guide before you commit to a design.

Common questions
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.
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 they leak?
Modern lanterns are sealed systems. Leaks usually trace back to the kerb or roof membrane detail, which we form and check ourselves.
