Why Back Tray Flashing is a Must

Installing a back tray flashing is highly recommended for any skylight positioned on a roof pitch under 15 degrees. Its design effectively removes the section of roofing sheet behind the skylight. As a result, when rain hits the back tray, it seamlessly diverts water into the sheet pan on either side of the flashing, preventing any potential leaks. Read our blog for more information

What our bases are made from?

All base flashings are made from .55bmt colorbond steel, unlike other suppliers who use a powder coating process which fades and deteriorates over time. Our pre fabricated bases can be made with two reveal types;

Timber reveal: Our pre fabricated bases come standard with a 70x35 treated pine timber reveal, this is not to be removed. The timber reveal not only adds strength to the base flashing, enhancing its durability and stability, but also serves as a thermal break. This is crucial for improving the insulation properties of the skylight, critical for achieving the Velux performance rating.

Metal reveal:  No timber reveal is needed, as the flashing has been specifically designed to replicate this detail with a 35mm x 35mm reverse fold. The skylight is secured directly to the base flashing. Please note all flat pack flashings are made with a metal reveal.
