Roof windows are a fantastic solution for any home that will help you bring more sunlight in. Regardless of what type of roof you have, roof windows are pretty much always a good idea. However, no roof window can be properly installed into your roof without the appropriate flashing. If you choose the proper flashing, you can ensure that your window will be completely weather-resistant and blended perfectly into the rest of your roof. Velux flashing kits are the most efficient way to guarantee just that for your roof windows. With this helpful guide, you can learn how to choose a Velux flashing that’s perfect for your home.

Know what you’re working with
It’s important to know what type of material you have on your roof. Your flashing kit has to be a perfect match to the angle and material if the result is to be seamless. Velux offers three basic types of flashings – tile flashings, plain tile flashings, and slate flashings. EDW flashing kits are designed for tiles on a 15-90 degree pitched roof, and they work great with Velux roof windows if you want to install them in flat or profiled roofing material up to 120mm in profile. EDL flashing kits are designed for slates on a 15-90 degree pitched roof, and they work great with slates up to 8mm in thickness, though they’re not suitable for interlocking slates. EDP flashing kits for plain tiles on 25-90 degree pitched roofs are best suited for plain tiles with a maximum length of 300mm, and the maximum thickness of the tile is 14mm.

Consider a recessed installation
There are two main flashing installation heights – standard and recessed. Recessed installations may just be the way to go for you, as they sit 40mm deeper into the roof structure, making them much better blended into the roof’s overall structure. Aside from looks, there are other benefits to recessed installations, including improved energy efficiency, as well as greater design flexibility for architects. Velux offers two flashing kits for recessed installations – EDJ for tiles on a 20-90 degree pitched roof, and EDN for slates on a 20-90 degree pitched roof.
Choosing installation accessories
You can save even more on energy and money by implementing several installation accessories that will match your flashing perfectly. An insulation collar can help insulate around the frame of your window, greatly reducing heat loss and cold bridges. An underfelt collar is attached to the structural opening with tape, adding another layer of weathertight seal between the window and roof. Finally, there’s a vapour barrier that can prevent excess condensation at any stage of the installation process.
