Metal and Colorbond Roofing Across the Ryde District

The sheet is the easy part

A Colorbond roof fails at its edges and its holes, never in the middle of a sheet. So a metal roofing job is really a job about flashings, fasteners, valleys, laps and drainage — and whether the person installing it understood the building underneath.

That is worth saying up front in this district, because the buildings vary enormously. A new steel roof here might be going onto a 1930s brick bungalow in Denistone, a near-flat section on a walk-up block in West Ryde, a modern addition on a Putney waterfront block, or a plant-room deck behind a parapet at Macquarie Park. Same material, four completely different specifications.

Where metal is the right call

Low pitch and near-flat sections

Tile needs a conventional pitch. Below that, water stops running and starts sitting, and it finds the laps. Metal profiles exist for very low pitches, and the specification is about long single sheets with no end laps, correct side-lap detailing and real overflow provision. Most of the near-flat roofing in the older centres is on 1960s and 70s brick flats, often behind a parapet with a box gutter, and that combination is unforgiving of a sloppy install.

Steep and awkward blocks

Across the ridges that fall away toward Glades Bay, Morrisons Bay and Buffalo Creek, plenty of houses are two storeys at the back and one at the front. Fewer, longer sheets mean less time on a difficult roof and fewer joins where things can go wrong.

Taking weight off old framing

Steel is a fraction of the weight of tile. On a house whose framing has carried a tile roof for eighty or ninety years, that is a structural benefit rather than just a cost saving.

Extensions and additions

Matching an out-of-production inter-war tile across a new addition is a real problem. A deliberate change of material on the addition, in a colour that sits with the existing roof, often looks better than a near-miss tile match.

Specifying for the water

The Ryde district has two very different exposures within a few kilometres of each other. Inland at Marsfield, Macquarie Park, Denistone West or Eastwood, standard material is appropriate. On the river and harbour frontages — Putney, Tennyson Point, Henley, Huntleys Point, Woolwich — salt-laden air is a real design input.

What we change close to the water:

• A coastal-grade finish rather than standard.
• Fasteners and flashings compatible with the sheet, so the join is not the first thing to go.
• No incompatible metal contact, including runoff from one metal onto another.
• Gutters and downpipes specified to the same standard, since they corrode before the roof does.
• Attention to sheltered areas that salt reaches but rain does not wash.

Heritage, conservation areas and material change

Replacing like with like on a standard house in the City of Ryde is usually uncomplicated. Changing material is the one that needs checking, because it changes what the street sees.

The City of Ryde LEP 2014 lists heritage conservation areas — expanded to eight in late 2020, among them the Darvall Estate and Chatham Road areas around Denistone and the Tyrell Street area in Gladesville. The Municipality of Hunters Hill, which covers Hunters Hill, Woolwich, Boronia Park, Henley, Huntleys Point and part of Gladesville, is stricter: complying development is not an available pathway inside its conservation areas, and council issues heritage exemption letters only for genuinely minor work, with the published example being a slate roof replaced in slate using matching flashings and capping.

In practice that means a tile-to-metal conversion is unlikely to be the right answer on a heritage house or in a conservation street, and we will say so rather than quote it.

What a metal roofing quote should spell out

• Profile, finish grade and colour, and the sheet length and layout.
• Fastener type and fixing pattern, and whether concealed or exposed fixings are used.
• Sarking, insulation and any ventilation included.
• Valley, ridge, barge, apron and wall flashings — material and how formed.
• Treatment of every penetration: flues, vents, skylights, aerials, solar mounts.
• Gutter, downpipe and overflow provision, sized to the roof area feeding it.
• Removal and disposal of the old roof, and any asbestos handled under a licensed removalist.
• Site access, edge protection and the sequence of work.

If a quote does not mention flashings and drainage, it is a price for sheets, not for a roof.

Related work

Metal roofing rarely arrives on its own. It is usually part of a full roof replacement, it almost always comes with new gutters and downpipes, and on the low-pitch sections it frequently follows a failure that began as a storm or emergency repair.

Work is carried out by established, licensed and insured roofing contractors working to NSW Fair Trading requirements, and the completed job carries a written workmanship warranty.
