So you’ve been given all the points to consider when selecting a Velux® skylight window….location, size, opening, etc. But has anyone ever told you what happens on top of the roof? That’s just as important as the skylight itself.
Skylight windows are held in place by a flashing. These range from plastic units, through to welded and painted steel. The quality and type of material will determine whether your new kitchen skylight turns into a shower with the first winter rains. Our flashings are made from genuine Colorbond® steel only because…well, why would you fix something that doesn’t have the benefits of Colorbond® steel onto a Colorbond® roof?
Whether it’s a single flashing for a small C01 window, to multiple flashings for several FCM & S06 size combinations, we have it covered.
A customer approached us to fabricate a custom flashing in Basalt® for three Velux® FCM2246 windows in a portrait orientation, on a metal deck roof. The spacing between the middle and outer windows were to be constrained to 200mm.
Two Colorbond® sheets are selected, and individual components measured out. A check-measurement is made, and the components cut in accordance with the specifications provided.
Individual components are then bent and folded, and the three Individual window flashings are fabricated and checked. Sealant is applied between flashing overlapping edges, and colour-matched rivets used for fixing.
The individual flashings are dry-fitted together on a workbench to determine the best location for rivet fixings during installation on the roof.
After pre-drilling the rivet holes, the three components are separated, a final sealant applied and the corners strengthened with our own custom solution.
During this entire process, the protective film is left on the steel, except at joins where sealant is applied or rivets are inserted. This film is only removed once the flashing is installed on the roof, ensuring the top of the flashing is not scratched.
