Why install a flat roof skylight? Can you install a skylight on a flat roof?

A flat roof skylight is a window in the roof. A skylight allows plenty of natural light into a property. A roof lantern can reduce the need for artificial lighting. Therefore, property owners save on energy bills.

Flat roof skylights offer noise reduction and insulation for a property – flat roof skylight installation can help property owners make further savings.


What is the minimum pitch for my flat roof skylight?

We can provide a wide range of flat roof glass skylight structures in our joinery. From domed roof skylights to pan flat skylights. The current minimum pitch for glass skylights for flat roofs is three degrees.

We can raise some standard fixed roof windows in a bevel like frame if required.

We make our skylights with high-quality hardwood and aluminium (with aluminium lantern roof lights). We finish each flat roof rooflight in a microporous paint from Farrow and Ball.


What size should I measure?

Choose your dimension and glass type along with styling and leave the rest to us!

We can offer glazed rooflights, domed skylights (flat roof skylight dome), walk on glass roof lights and specialist roof lights. Specialist roof lights are circular, hexagonal or shaped to your preference.

We provide flat roof skylights in all standard and custom sizes. Our lead times are short and we have a good delivery service.


What is a U-value?

The U-value measures how effective a material is at insulating.

Our flat roof lights are energy efficient. They are all manufactured from responsibly sourced timber. Each roof light has a good thermal U-Value for excellent heat insulation. All wood is treated to ensure a long, low-maintenance life.


What is a thermal break?

A thermal break is a barrier preventing heat loss through a conductor.  An example of a thermal break is the gas between glass window panels. This thermal barrier forms insulated glazing.


Are flat roof skylights easy to maintain?

Our flat roof windows are low-maintenance. Flat roof window lights can come with glass that is self-cleaning and solar controlled. We can match the colours of the product to the surrounding features. These features include the roof trim, existing windows and render.

We can manufacture square, rectangular, triangular, circular or hexagonal roof lights. We can also provide custom-shaped skylights.

Installing roof lights has a positive impact on the lighting within the room, without affecting the temperature of the room. The additional light can create space in a room too. Do you want to make your home feel bigger and fresher?

Of course you do!

So, contact us if you require a bespoke, made to measure flat roof skylight. We can also provide specialist, custom fabricated rooflights.

Contact us and we’ll provide a free, no pressure quotation.  We can also supply to trade.


Will it be too noisy if it is raining?

Did you know? Flat roof skylights for homes tend to be a popular choice in loft conversions.

We appreciate any concerns that rainfall will be noisy. After all, we rarely go a few days without rainfall in the UK! And that’s why our roof lanterns are made to minimise noise from rainfall.


Do flat roof skylights add value to your home?

Natural light is a big selling point when it comes to attracting buyers. Energy-efficient and high-quality skylights improve the quality of life of living in a property, meaning they add value and appeal to potential buyers.


Are flat roof skylights worth it?

Any home improvement project needs to do not only improve how you live in your home, but how it feels to live there too. A room that is filled with natural light is always a desirable space. You won’t regret investing in flat roof skylights.


Do flat roof skylights need to be replaced?

Flat roof skylights rarely need replacing especially when you invest in both quality skylights and installation. Offering many years of service without the need for repair or replacement, skylight frames and flashing may need replacing but not for decades.


How many years do flat roof skylights last?

A quality flat roof skylight that is professionally installed will last for decades. Regular inspections helps to spot problems early, especially after prolonged periods of poor weather such as heavy rain, high winds or sub-zero temperatures.


How do you know if your flat roof skylight is leaking?

Aside from drips into the room below when it is raining, if you notice the skylight window misty or condensation appearing, it may mean rain is seeping in through cracks or holes in the frame or flashing around the base of the skylight.


Why do flat roof skylights crack?

Plastic skylight windows may crack over time. But glass flat roof skylights rarely crack. Made from tempered glass with a laminated surface, glass skylights weather all kinds of storms and issues without cracking.


Why are flat roof skylights energy efficient?

Low U-Value flat roof skylights prevent heat being lost through the glass, meaning more heat stays in your home and less cold air finds its way in. Over time, you will save money on your heating bill as the highly energy-efficient glass in skylights will not be allowing heat to escape but plenty of light to flood in.
