General Permits and Requirements for Roof Replacement in Melbourne03 December 2021
Under Part 4 of the Plumbing Regulations 2018, roofing (stormwater) work is the construction, installation, replacement, repair, alteration, maintenance, testing or commissioning of any roof covering or roof flashing, or any part of a roof drainage system. These are involved in the collection or disposal of stormwater, and includes the connection of any stormwater piping to a below-ground stormwater drain; or an on-site retention tank; and any design work that is incidental to or associated with any work described in this sub-regulation.
Typical Roofing (Stormwater) Work
Roof plumbing work involves a roof drainage system that collects and disposes of stormwater. Many factors affect how quickly water drains off a roof, if water drains completely and if the roof is watertight. A roof drainage system usually comprises gutters, eaves and downpipes.
What Do Roofing (Stormwater) Plumbers Need To Know And Do?
Roofing plumbers must understand how water behaves under different conditions, including wind, heat and cold. They must also understand fundamental roofing principles such as capillary action and electrolysis. They must be comfortable working outdoors and at heights. What does this mean for you? As a registered practitioner, you must understand and apply the compliance requirements of Roofing (stormwater) plumbing work.
These requirements include AS3500 National Plumbing and Drainage Code, HB 39 Installation code for metal roof and wall cladding, HB 114 Guidelines for the design of eaves and box gutters.
To undertake Roofing (stormwater) work to a safe and competent standard, you must also be able to: work safely at heights, including on scaffolding or elevated work platforms, know the different types of roof flashing and how they differ, know which roof materials are not compatible, perform calculations and measurements necessary to use roofing materials and install a roofing system.
What Competencies and Experience Do You Need?
The VBA publishes a set of units of competency for each class of plumbing work. Each competency describes a work outcome, all the knowledge and skills needed to do the work to the expected standard, and how they should be assessed.
The VBA uses the units of competency to assess your skills and experience if you apply to register in a class of plumbing work. To be eligible to register in the Roofing (stormwater) class, you must show that you have the relevant competencies plus recent and relevant experience in work related to the Roofing (Stormwater) class of plumbing.
