Looking for glazing options for your extension? Choosing between roof lanterns and flat rooflights depends on your design goals, budget, and practical needs. This guide helps you weigh both options and make an informed choice.
In this guide, we’ll compare Roof Lanterns and Rooflights side by side to help you make the best decision.
What’s the Difference between Roof Lanterns and Rooflights?
Roof Lanterns
Roof lanterns are elevated, three-dimensional glazed structures—often in pyramid or prism shapes—that sit above the roof level. They bring in light from multiple angles, enhance room height, and create a striking architectural feature.

Rooflights
Flat rooflights are sleek, flush-mounted glass panels that sit almost level with the roofline. Their minimalist design is modern and discreet, ideal for understated elegance.

Key Comparison Factors
Aesthetics & Architectural Impact
- Roof Lanterns offer a bold visual statement—ideal for orangery-style spaces or open-plan layouts.
- Rooflights provide a clean, minimalist look, seamlessly integrated into the roof for a subtle finish.
Which Option Gives More Light?
- Roof Lanterns capture light from multiple directions, filling large or deep spaces more evenly.
- Rooflights deliver direct overhead illumination—great for targeted areas or long, narrow rooms.
Installation & Maintenance
- Roof Lanterns with their complex frames and elevated structure, may take longer to install and clean – but offer enhanced rainwater shedding.
- Rooflights tend to be easier and quicker to install, with cleaner lines and fewer visual interruptions.
Cost
- Roof Lanterns command a higher upfront investment but add architectural value.
- Rooflights are typically more budget-friendly both in purchase and installation.
Planning & Regulations
- Roof Lanterns may require planning permission depending on height and location, although they often fall under permitted development.
- Rooflights often fall under permitted development due to their low elevation and minimal visibility.
