There have been a few changes lately with regards to the minimum fall requirements for gutters, decks and flat roofs in the Auckland region. We now have clarification and approval from both ARDEX and Auckland city council for the following minimum falls;
For ARDEX Butynol, ARDEX Shelterbit (Torch-on) and ARDEX TPO
Roofs: - 1:30 (2 Degrees)
Decks - 1:40 (1.5 Degrees)
Gutters - 1:100 (.6 Degrees)
NB: Although 1:100 is the MINIMUM requirement for gutters, we always advise as much fall as is possible under the circumstances!
