How we approach roof lanterns in Prescot
Thinking about roof lanterns in Prescot? 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.
Stone and brick terraces are typical across the North West, and roof windows in rear slopes are a common way to light attic rooms. In Prescot, as anywhere, roof lanterns are the usual choice for rooms that need height as well as light.
From Prescot to Huyton, St Helens and Halewood, the same survey-first process applies: measure, specify, fix the price, then fit.

Planning, building control and Prescot
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. 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.
Under Approved Document L, a rooflight added to an English home must achieve at least 2.2 W/m²K (horizontal plane), and a roof window 1.4 W/m²K or Window Energy Rating Band B. 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 Prescot
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.
How big can a lantern be?
Aluminium systems go to around three by six metres in standard ranges; larger sizes are made to order.
Can you work alongside my builder in Prescot?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
Is the survey in Prescot free?
Yes for new installations. Repair visits are charged, and we tell you the price before we book.
