What is Fast Flash?
Fast Flash is a flexible, environmentally friendly, self-adhesive roof flashing made aluminium stretch netting cast in flexible polymer rubber. It conforms to a wide range of roofing materials and is ideal for sealing roof valleys, solar panels, skylights, ventilation caps, gutters, and chimneys. Fast Flash is a sustainable alternative to lead sealant, offering a faster, non-toxic, and efficient waterproofing solution for commercial and residential roofing.

Colours
Fast Flash is available in four colours that are designed to match Brisbane roofing materials:
- Grey
- Black

Benefits of Fast Flash

Easy Application
Fast Flash is easy to apply; the fully adhesive backing means that and it can easily be moulded into place on metal and tile roofs by hand and removes the need to cut or reshape metal flashing.
Adheres to a Wide Range of Roofing Material
Fast Flash is suitable to apply to a wide range of roofing materials including metal (Colorbond), tiles, concrete, polycarbonate, exposed brick, rough concrete, timber, and glass.
Inexpensive
Fast Flash is a cost-effective alternative to traditional lead flashing. Whilst the cost of the rolls is not considered ‘cheap’, it greatly reduces installation time and cost as it’s faster and easier for tradesmen and roofers to install.
Lightweight and Durable
Fast Flash is lightweight, weatherproof, and UV rated. It displays no deterioration in extreme temperature ranges, so will protect your roof for years to come.
Flexible
Fast Flash is extremely flexible, malleable, and stretchable and can be easily shaped by hand. It can be moulded to tightly fit any roof profile and can be folded around corners.
Time-Saving
Due to the ease of installation, Fast Flash can cut installation time by up to 50% in comparison to traditional lead flashing.
Environmentally Friendly
Fast Flash is an environmentally friendly, lead-free alternative to traditional flashing, making it safer for installers. The aluminium stretch netting and polymer rubber materials don’t have any impact on water quality so it is also considered safe if harvesting drinking water in rain water tanks.
