Buy the Right VELUX Flashing - 5 Questions We Ask Customers

Published on Monday, 29th February 2016

VELUX flashings are essential for your window installation. Getting the right flashing is incredibly important, and buying the wrong flashing kit can put back your renovation project as you wait for the right one to be delivered.

We asked Tyler from our sales team how he helps our customers get the right VELUX flashing kit they need.

Let's kick off with what are VELUX flashings for? Flashings are designed to ensure you get a completely weathertight fit for your new or replacement window into your roofing material.

With the variety of roofing materials VELUX flashing kits go on, it can sometimes beg the question “which one do I need?” I want this to be an easy choice for you, without any mistakes, so I've made this guideline for you to follow before making your purchase with Sterlingbuild.

1. Tell me about your roof

Like your VELUX window, your flashing kit has match the angle of your roof. It also has to complement your roofing material. It sounds obvious, but this can be overlooked!

Below is a table to help you answer these questions:

Flashing | VELUX EDW

Tiles on 15-90° pitch roof

VELUX EDW flashing kits are for the proper installation of a single VELUX roof window on a roof with tiled roof.

EDW flashings offer a standard (as opposed to the more energy efficient recessed) installation of a roof window into flat or profile roofing material. The deep tiles must have a maximum 120mm profile. They can also be used on interlocking slate, thatch and profiled sheeting. The roof must have a pitch between 15 and 90°.

Flashing | VELUX EDP

Plain tiles on 25-90° pitch roof

VELUX EDP flashing kits are for the proper installation of a single VELUX roof window on a plain tiled roof.

EDP flashings offer a standard (as opposed to the more energy efficient recessed) installation of a roof window into flat or profile roofing material. The plain tiles must have a maximum length of 300mm and 14mm thick. The roof must have a pitch between 25 and 90°.

Flashing | VELUX EDL

Slate on 15-90° pitch roof

VELUX EDL flashing kits are for the proper installation of a single VELUX roof window on a slate roof.

EDL flashings offer a standard (as opposed to the more energy efficient recessed) installation of a roof window into flat or profile roofing material. The slate must have a 8mm profile or less. The roof must have a pitch between 15 and 90°. This flashing kit isn't suitable for use with interlocking slate (you will need VELUX EDW flashings).

2. Do you want a more energy efficient installation with a tidier external finish?

Not all of us are blessed with the vision of some roofers, and so a preview of what a window and flashing combination will look like once installed can be a difficult task. VELUX offers 2 installation heights: standard and recessed. The best way to describe the differences is by using VELUX’s own guidance:

“Recessed installations offer a more sleek, streamlined appearance, sitting 40mm deeper in the roof structure. Recessed installations also offer greater energy efficiency, and when installed with the appropriate VELUX insulation collar actually offer a lower certified U-value, saving energy and providing architects with greater design flexibility.”

Flashing | VELUX EDJ

Tiles on 20-90° pitch roof

VELUX EDJ flashing kits are for a weathertight recessed installation of a single VELUX roof window on a tile roof.

EDJ recessed flashings offer a deeper installation of a roof window in the roofing material. The tiles must have a 90mm profile or less. The roof must have a pitch between 20 and 90°. EDJ 2000 includes a VELUX BDX insulation collar, which, together with the recessed flashing, will give a vastly improved energy efficient installation.
