Colorbond Flashings

Flashings are where metal roofs fail. Not in the middle of a sheet run, but at the junctions: roof to wall, roof to parapet, around penetrations, at the rake and the ridge. Get the flashing wrong and the rest of the roof is irrelevant.

HMR Supplies folds Colorbond flashings at Revesby, in the colour and gauge your job actually needs, from either a standard profile or your own drawing. If you can draw it, we can fold it.

Quality roof flashings for high-performance building protection

Roof flashings are a critical yet often overlooked element of water management. While larger panels handle the majority of runoff, flashings are the essential components that protect vulnerable junctions where metal roofing products meet walls, chimneys or other roof penetrations.

At HMR Supplies, we manufacture precision flashings that create a watertight barrier at these critical intersections, preventing the leaks and moisture infiltration that often lead to rot and structural damage.

Precision-engineered standard and custom profiles

We understand that no two builds are identical, which is why we offer a versatile range of profiles to suit any requirement. From standard apron and ridge flashings to bespoke geometries designed to your exact drawings, our team provides the technical flexibility you need. Whether you require a traditional look or a unique architectural detail, we can manufacture metal roofing products that fit perfectly.

For penetrations that cannot be flashed with sheet metal, we also stock formable and moulded solutions: Fast Flash, Rapid Flash and Dektite for pipe penetrations.

Custom Flashings From Your Drawing

Most jobs above a certain size need at least one piece that is not on the list. Parapet returns on a heritage facade, a box gutter transition into an existing wall, or an awkward valley junction on a knock-down rebuild.

Send us the section. Our in-house CAD team will draw it up, confirm the girth and the break positions with you, and it goes on the brake once you sign off. Custom profiles up to 8 metres in length and 4mm in thickness can be manufactured to suit project requirements.

Where a flashing needs more than folding, we also run laser cutting , welding , custom fabrication and powder coating under the same roof, so a fabricated part does not have to be shipped between three suppliers to get finished.

Materials, Not Just Colorbond

Colorbond is what most Sydney jobs ask for, and it is what we hold the most coil in. It is not the only option.

The important rule is compatibility. Mixing metals across a junction, or using the wrong fixing against a substrate, sets up galvanic corrosion that will show at the flashing long before it shows anywhere else.

If you are flashing a copper roof, the flashing, the fixings and the fasteners all need to be compatible with copper. Ask us if you are not sure. We would rather answer the question than replace the flashing.

Three Things That Decide Whether a Flashing Works

01

Girth Before Colour

Roofers ring up with a colour and a length and no girth. Girth is the flat width of the sheet before it is folded, and it is the number that determines whether the flashing covers the junction or lands two centimetres short. Measure the full developed width, including every leg and turn-up.

02

Upstands and Turn-Ups Matter More Than Laps

A flashing that laps beautifully but has a 15mm upstand against a wall will still let water in under wind pressure. Design the upstand for the exposure of the elevation, not for the easiest fold.

03

Order the Set Together

Flashings from the same coil batch match. Flashings ordered a month apart may not, particularly on the darker Colorbond colours. If the job needs barge, ridge and apron, order them at once.

Installation of metal roof and wall cladding flashings in Australia is covered by AS 1562.1 and the relevant NCC provisions. Confirm the current edition and the wind classification for your site before you finalise fixing centres and lap dimensions.

FAQs

Flashings provide a waterproof barrier for roof joints and intersections. They prevent moisture from entering at roof-wall junctions and penetrations, protecting the structure from leaks and structural rot.
