Roof lantern installation in Billingshurst
- 01
Why choose a roof lantern
A roof lantern rises above the flat roof like a small glass pyramid or ridge. It lets in light from every direction and makes a room feel taller. It's a popular way to brighten the middle of a deep kitchen extension that windows alone can't reach.

Sizing your lantern
The lantern should suit the size of the room below, often taking up a good part of the ceiling without crowding it. The joists, the roof covering and the upstand height all affect the size that will work. We measure up and suggest sizes that look in proportion.

Frames and glazing
Most modern lanterns have slim aluminium frames with double or triple glazing. Solar control and self-cleaning glass are worth considering, especially on a south-facing roof. Some lanterns include opening vents that let warm air out on hot summer days, so the room stays comfortable.
What to expect from roof lantern installation
We start by looking at the flat roof, the joists and the room below, and talk through lantern size, frame colour and glazing. Your free quote covers the lantern, the upstand, any structural work and the roofing around it.
On the day, we cut the opening and trim the joists, build a timber upstand and weatherproof it into the roof covering. The lantern frame and glazing go on next, and everything is sealed and checked. Inside, the opening is left ready for plastering.

Roof lantern installation questions
How much does roof lantern installation cost in Billingshurst?
The price depends on the lantern's size, frame, glazing and any opening vents, plus the structural work to form the opening. Adding a lantern while a new flat roof is being laid usually costs less than cutting into a finished roof. We give you a free quote first.
Does a roof lantern need building regulations approval in West Sussex?
Often, yes. Cutting a new opening in a roof is a structural change, and the glazing has to meet energy rules, so building control is usually involved. A lantern fitted as part of a new extension is normally covered by that project's approval. We'll explain what applies.
Can a roof lantern go on my existing extension in Billingshurst?
Usually, yes, if the flat roof and joists can take it. We check the structure and the condition of the roof covering first. If the joists run the wrong way or the roof is near the end of its life, we'll explain what extra work is needed.
Do roof lanterns get dirty or leak around Horsham?
Like any glazing, lanterns collect dirt and leaves, and self-cleaning glass helps. A well-fitted lantern on a properly built upstand should stay watertight. Most leaks come from poor seals into the roof covering, which is why we take care over the roofing around the frame.
