Roof Drains – Dome, Flat & Scupper
FLOZN roof drains handle rainwater on flat roofs, terraces, podiums and parapets. Cast iron bodies with membrane clamps give a watertight seal with the roof waterproofing, topped with removable aluminium domes, flat grates or angled scupper grates.
For finished terraces and balconies, the stainless steel scupper drain gives a flush, architectural finish.

Frequently asked questions
Which roof drain should I use on a flat roof?
The dome-type FZ-5D-A4 is the standard choice for flat roofs – the raised aluminium dome resists blockage from leaves and debris. Use the flat FZ-5F-C4 where the roof is trafficked.
What is a scupper roof drain?
A scupper drain sits at the junction of the roof and parapet wall and discharges horizontally or vertically. FLOZN offers a cast iron FZ-5S-A4 and a stainless steel FZ-5S-S4.
Can I add a gravel guard?
Yes – an SS perforated gravel guard or SS mesh cap is available for the dome drain, and an SS mesh cap for the scupper.
Which outlet sizes are available?
4" is standard, with 3" and 2" outlets or PVC adaptors available.
