Once you’ve decided to add roof windows to your living space, there are some important things to consider. Think of the process as two simple steps:
Now, let’s discover how to do this.
Roof windows are a smart, energy-efficient way to transform dark, underused areas into bright, airy spaces – but only if they’re placed in the right spot.
Planning a full loft conversion? Updating a tired extension? Or simply adding value with light over a stairwell? The position of your window will determine how much daylight, ventilation, and comfort you gain.
The main reason homeowners and renovators choose a roof window is the flood of natural light it provides. A general rule of thumb is that the glazed area should make up around 10–20% of the room’s floor area.
In lofts or flat-roof extensions, roof windows can make a dramatic difference to brightness.
The placement of your roof window plays a big role, too:
For a consistent influx of natural light, we recommend installing roof windows on the south side of a building where possible.
But it’s not just about light.
Roof windows also help remove stale air and reduce moisture build-up, especially in bathrooms, kitchens, and attics.
Placing roof windows opposite or above doors improves airflow dramatically. This cross-ventilation can reduce condensation, improve indoor air quality, and even help regulate temperatures in warmer months.
There are several areas in a home where installing a new roof window can offer maximum benefits. Below are some of the most common—and impactful—locations:
If you’re planning a loft conversion, installing a roof window is almost essential. These spaces are often dark and stuffy, but a properly placed roof window can flood the area with daylight and fresh air.
This extra living space can translate to additional revenue should you wish to convert to a HMO, or even provide you with a new area to unwind.
Recommended Dakea Options for Lofts:
Lofts also benefit from the fact that roof window installations can be done directly on pitched roofs, which are ideal for many of Dakea’s roof window types.
Modern home extensions, particularly those with flat roofs, often lack the vertical wall space for standard windows. In this case, flat roof windows allow much-needed light to flow in whilst adding some subtle style.
Best Dakea Options for Extensions:
Stairwells are often overlooked, but installing a roof window here can make a huge impact. These transitional spaces benefit from consistent light throughout the day and become more inviting and functional.
Installation Tip:
Centre-pivot windows are ideal here for ease of operation and to avoid obstruction.
Moisture-prone rooms like bathrooms and kitchens need effective ventilation as well as natural daylight. PVC roof windows are a good idea here, offering excellent moisture resistance and easy cleaning.
Recommended Dakea Option:
In today’s hybrid working world, having a bright, well-ventilated home office is more important than ever. Installing a new roof window in your attic office or garden studio can boost your mood, productivity, and wellbeing.

Beyond their practical benefits, roof windows help foster a sense of comfort and well-being. Bright, well-ventilated spaces tend to feel more open and less confined, positively impacting stress levels and overall happiness. Whether it’s a sunlit reading nook or a fresh breeze in a warm attic, roof windows improve the quality of daily life.
High-quality roof windows, like those from Dakea, come with laminated or triple-glazed options that significantly reduce external noise—whether it’s traffic, rain, or neighbourhood activity.
We pride ourselves on making high-quality, energy-efficient roof windows accessible. Thanks to our streamlined range, trade-friendly pricing, and expert support, we make specifying and installing new windows simple.
In most cases, roof window installation falls under permitted development, but always check with a structural engineer or local planning authority.
A skylight is usually non-opening and designed for uninhabited spaces. A roof window is suitable for habitable rooms and offers ventilation.
Consider your roof type, room usage, and how much light and ventilation you need. Or speak to a Dakea stockist or roof window installer for guidance.
