Your Go-To Guide When Looking for Flat Roofing Windows and Rooflights

Posted by admin In

Flat roofing rooflights and windows have become popular over the past few years. They help encourage energy efficiency in your property and reduces your dependency on artificial lighting. This guide contains everything you need to know before purchasing rooflights or windows for your property. 

Windows for Flat Roofing

There are two main categories of roof lighting that you can choose from; off-the-shelf and custom-made solutions. 

Off-the-Shelf

This option offers rigid fixtures made to fit into standard designs. Glass is the most preferred material used for different reasons, including its long lifespan - but it comes with a slightly higher price. Velux is the most popular supplier for different kinds of glass roof windows. You might also consider a sun tunnel, especially if your roof usually struggles to naturally receive sunlight. 

Polycarbonate is another option that’s cheaper and comes in either double or triple skin. It can also be used for venting in cold flat roof structures. 

Custom-Made

As the name suggests, custom-made solutions are those that can be designed to fit almost any requirement. You’ll have a variety of options to choose from. Glazed rooflights are often designed for most roofs. You can also use pyramid designs, domes, or roof lanterns if you’re looking for something more unique on the roof surface.  

What to Consider Before Buying the Flat Roof Windows and Rooflights 

Planning permission is rarely a requirement for flat roof rooflights or windows. However, there are other factors that you need to consider to ensure you have the right product for your needs. Below are some of the factors:

Window/Rooflights Position

You need to think about where you want to install the window/rooflights and its intended function. You’ll have to consider the extent of UV exposure, especially for south-facing properties. Directional placement will determine whether glazing with higher UV protection levels is required. It also affects the type of glass to be used. Your safety is paramount when determining the position for the rooflights and windows. Ensure to have a proper fall protection, such as free-standing demarcation, in place before accessing the roof. 

Access and Ventilation

Rooflights and windows provide points of access to the surface of the roof, making roof inspection and maintenance easier and more convenient all year round. They also help provide efficient ventilation, especially during the warmer months.

Sizing

Besides the positioning of rooflights and windows, it’s also important to consider their size. Larger sizes means more natural light coming in and hence more exposure to the dangerous UV light. You need to balance the amount of natural light coming in from vertical windows with that from the roof. 

Upstands

These are the frames that sit around the rooflight. It’s always recommended to create them separately and not as one whole structure. This is to allow for a smooth installation of the roofing membrane before the rooflight is installed. It’s also essential for proper natural drainage and ensures no damage to the roof structure during the routine maintenance and repairs or maintenance.  

Installation

There are several installation companies available on the market. You should always look for one that’s British Standards Institution (BSI) certified. This way, you can rest assured of their adherence to industry standards and the quality of work delivered.  

The Bottom Line

Rooflights and windows tend to collect dirt and stains over time due to their positioning and the nature of materials used. You’ll need to embrace regular cleaning and maintenance to keep them in good condition.
