Industrial Roofing Contractors in Sydney

Industrial roof replacement and re-sheeting for Sydney factories and warehouses, staged around a working site. Real project scopes and programmes inside.

Austek replaces, re-sheets and repairs roofs on factories, warehouses, logistics sites and processing facilities across Sydney and NSW. Most of that work happens over a building that has to keep running while the roof above it comes off, and the way a job is staged matters as much as the sheet that goes back on.

We have been doing this since 2010. Below are three real industrial roofs we have replaced, what each one involved, and how long it took.

What we do on industrial roofs

  • Full roof replacement. Strip the existing roof, check the structure underneath, and install a new roof in a profile suited to the span and pitch.
  • Profile upgrades. Corrugated to a concealed-fix trapezoidal profile such as Speed Deck, where long runs or low pitch call for it.
  • Gutters and drainage. New eaves and box gutters as part of the re-roof, while access is already in place.
  • Ventilation and daylight. Whirlybirds and skylight sheeting, built into the new roof rather than cut in afterwards.
  • Roof safety and access. Safety rails and walkways integrated with the new roof. See height safety systems for anchor points and static lines.
  • Services reinstatement. Plant, conduits and penetrations taken off and put back, flashed into the new sheet.
  • Repairs. Leaks, storm damage, failed flashings and corroded sections. That work sits under industrial roof repairs and maintenance.

Three Sydney industrial roofs, side by side

Site Year Roof area Programme Scope The constraint
Rydalmere roof replacement 2017 650 m² 2 weeks Full roof removal and replacement, all existing services reinstated, new guttering Tight two-week window, building kept watertight throughout
Moorebank industrial re-roof 2019 1,300 m² 8 weeks Ageing roof replaced with corrugated, whirlybirds, skylight sheeting Operational site, delivered as a staged replacement
Silverwater roof replacement with safety rails and walkways 2018 400 m² 4 weeks Full replacement to Speed Deck, safety rails and walkways integrated Live industrial environment, safe access maintained at height

Read the table by programme rather than by area. The smallest roof of the three, Silverwater, ran twice as long as Rydalmere. Its scope also included safety rails and walkways, in a live industrial environment. Moorebank was twice the area of Rydalmere and ran four times as long. It was a staged replacement over an operating site, and it added whirlybirds and skylight sheeting.

That is the honest answer to “how long will our re-roof take”: area sets the materials, scope and site conditions set the programme. A quote that gives you a duration without asking about your operating hours has not planned the job.

How an industrial roofing job runs

1. Inspection. Someone gets on the roof and underneath it. Sheeting, fixings, flashings, gutters, penetrations, safety systems and the structure visible from inside. This is what a commercial roof inspection covers, and on an industrial building it is the step that decides between repair and replacement.

2. Scope and staging plan. Which bays come off first, what has to stay dry underneath, which services need isolating, and where deliveries and cranes go so they do not block your loading docks.

3. Pre-start documentation. Safe work method statements, access and exclusion zones, and the plan for any fragile surfaces such as old skylights.

4. Staged replacement. On an operating site the roof is opened only as far as can be closed again before weather or end of shift. Moorebank was delivered this way over eight weeks.

5. Services, drainage and handover. Plant and penetrations reinstated and flashed, gutters connected, and the roof left with safe access for whoever maintains it next.

What to have ready before you ask for a quote

You will get a faster and more accurate price if you can tell us:

  • Site address and approximate roof area, or a roof plan if you have one
  • Current roof profile and roughly when it was installed
  • Operating hours, and any areas that cannot be disrupted (cold rooms, production lines, stock)
  • Your asbestos register, for any building built before 1990
  • What sits on the roof now: plant, solar, exhaust fans, skylights
  • Whether the roof has anchor points, static lines or walkways today

Materials

We work with materials from Australian manufacturers including Colorbond steel by BlueScope, Lysaght and ARCPANEL. Profile, substrate and coating are specified to the building: span between purlins, roof pitch, what the building is used for, and how corrosive its location is. For the detail on material choices, compliance and maintenance planning, read our complete guide to industrial roofing in Australia.

Frequently asked questions

Do you provide free quotes for industrial roofing?

Yes. We provide free, no-obligation quotes for industrial roofing and cladding work. On larger roofs the quote follows a site inspection.

What types of industrial buildings do you work on?

Warehouses, factories, logistics centres, processing facilities and large commercial and industrial buildings across Sydney and NSW.

Can you work around our operating hours?

Yes. Works are staged and sequenced with your site manager so the building stays operational. Moorebank and Silverwater were both replaced over working sites.

Do you do emergency industrial roof repairs?

Yes, for leaks, storm damage and urgent roofing hazards. Our maintenance and repairs team is available 24/7 for emergency call-outs across Sydney. Ongoing work is covered under industrial roof repairs and maintenance.

What happens if the old roof contains asbestos?

Asbestos roofing removal is separate regulated work under SafeWork NSW requirements, carried out by a licensed asbestos removalist and planned before any sheet is lifted. Tell us at the quote stage if your register lists it.

What paperwork should we ask an industrial roofing contractor for?

A safe work method statement for the task, a current certificate of currency for public liability and workers compensation, and a written programme. Ask before anyone attends site.

Book an industrial roof inspection

The cheapest point to fix an industrial roof is before water reaches stock, production or electrical plant. Send us the site address and roof area and we will arrange an inspection and a staged scope.
