What is the Difference Between Rooflights and Skylights?

In the realm of architectural design and home improvement, rooflights and skylights play pivotal roles in illuminating interior spaces with natural light. However, despite their similar purpose, distinguishing between rooflights and skylights can be confusing for many homeowners and building enthusiasts. In this comprehensive guide, we delve into the differences between these two lighting solutions to help you make informed decisions for your space.

show the difference between rooflights and skylights

What is a Rooflight?

Rooflights, often known as flat rooflights, are glass units bonded into a frame designed to sit flat or low-pitched roofs (commonly 0-15 degree pitch). Serving as windows for flat surfaces, they are engineered to on an upstand (also called kerbs) to allow proper weathering. This providing a sleek and modern aesthetic.

What is a Skylight?

Skylights, distinct from rooflights, are windows strategically placed on pitched roofs to introduce natural light into elevated spaces like lofts and attics. These roofs are commonly tile, slate or even metal and required to tie into these with a flashing kit to keep the rooflights weathered. Unlike rooflights, skylights designed to sit inline with the roofing.

What Are The Benefits?

This section uncovers the numerous advantages of both rooflights and skylights. From energy efficiency and reduced reliance on artificial lighting to the positive impact on mood and well-being, discover how these architectural elements contribute to sustainable living and improved living spaces.

Ventilation and Airflow: Many skylights are equipped with operable vents or motorized mechanisms that allow for improved airflow and ventilation, promoting better indoor air quality and comfort

Architectural Statement: Skylights serve as architectural focal points, adding visual interest and character to the exterior and interior of residential and commercial properties.

Types of Rooflight and Skylight

Explore the diverse world of rooflights and skylights. From fixed to vented, operable, modular, walk on and smoke AOV options:

Fixed Rooflights: Non-opening units that are the most cost effective way to get natural light in a roof. Sleek and simple.

Sliding Rooflights: Designed with a weight-supporting mechanism and trackless operation, sliding rooflights provide effortless access to natural light and fresh air. The absence of tracks ensures seamless operation while maximizing the influx of daylight into the room.

Modular Rooflights: Modular rooflights offer versatile solutions for various architectural designs. By splitting roof openings into multiple rooflight panels it allows greater spans, ease of install, cost reduction and options for fixed and opening panels in line.

Walk-on Rooflights: This style is a preferred choice for terraces, rooftops and patios that have foot traffic. Engineered with thick multi panel laminated glass, these units offer enhanced strength while maximizing natural daylight penetration into indoor spaces.

Electric Opening Rooflights: Ideal for brightening up rooms and facilitating ventilation, electric rooflights feature electric hinges that enable convenient control via a panel or remote. This mechanism is particularly advantageous for installations in high or hard-to-reach ceilings.

 Access Rooflights: Access rooflights are designed to provide both illumination and accessibility to rooftops. They offer the perfect solution for spaces where occasional roof access is needed.

AOV Rooflights: Automated Opening Vents that enhance both brightness and ventilation, controllable via a remote or designated panel and used in conjunction with smoke control.

What is a Lantern Rooflight?

An alternative option to get natural light for flat roof is Lantern rooflights. Lanterns stand out as unique architectural features that add a touch of sophistication and a classic feel. It typically features a raised, central structure with sloped sides, this design allows for larger expanses of glass, providing panoramic views and creating a sense of openness.

EOS Rooflights were knowledgable in their field, very helpful and the products (Roof Lantern and Flat glass roof lights) were of a good quality. The Roof lights were easily installed and full installation instructions were supplied for those who are installing for the first time. Would recommend.

Very efficient with processing my order and delivery. I ordered a 3M roof lantern and a smaller flat roof light. Both were simple to install on my own upstands and they both look great. My only negative was the cost was a lot for what they are but I don’t think eos are excessively expensive, I think the roof lanterns themselves are what’s pricey. Anyhow I’m happy 😃

EOS were brilliant all through the consultation/sales process and delivery. The skylight looks great and works a treat with the electronic switch. Their after-care support was also very helpful and patient when we mistakenly thought we had an issue. Would highly recommend them.

As a company we have used EOS for some time. We use the EOS Rooflight Flexi Lid product a lot and also the EOS Smoke Vent Rooflight AOV on our projects. We cannot fault the company for the service, communication and value for money.

Excellent products, great customer service and post sales support! Unfortunately the courier damaged our roof lights slightly, however EOS went above and beyond to rectify! Special mention to Natalie O’Hara in ops, she was so helpful, prompt and a real pleasure to deal with! Highly recommend EOS!

The rooflights are a key feature externally of the property as they are prominent on the flat roof. They are angled by 15 degrees to allow the south facing sun to enter the house maximising natural light and also utilising any solar gain. The majority are triple glazed, with a couple of larger opening lights being double glazed. Internally they provide so much light and the light shafts are a characteristic of the internal architecture given that there are 15 within the house. The ordering and supply process was straightforward and installing them worked well with the pre-made upstands. All in all a very satisfactory and successful decision to select Eos rooflights.

I was after rooflights with laminated glass and of good quality! I contacted EOS after seeing and viewing their products. They fitted the requirements. The service was first rate, nothing was a problem and the drawings to work before delivery excellent. Would highly recommend.
