Commercial roofing is a different problem from residential. The roofs are bigger, the access is harder, the failure modes are different (lots of penetrations, lots of fastener fatigue), and the budget is approved by a small business owner or strata manager who wants line-itemed scoping, not a verbal “around X dollars”.
Commercial roofs are bigger, flatter and more exposed than residential ones, and a leak usually means lost trading time — so scheduling around your business hours matters as much as the repair itself.
What we cover
Industrial / warehouse re-roofs
Trimdek 0.42mm, Klip-Lok 406 / 700, full Bluescope range. 300–2,000sqm jobs, fall-arrest setup required for OH&S, often staged in sections to keep the operation running. Sarking, anticon, and skylight integration as part of the spec.
Light commercial re-roofs
Strata blocks, retail premises, small-business workshops, mechanic’s shops. Usually 100–400sqm, often with neighbour coordination (water discharge, parapet shared boundaries).
Office strata roofs
Multi-tenancy buildings under strata management. Quoting goes through the strata manager and AGM approval — we’re comfortable with the longer decision cycle and quote-format requirements.
Skylight integration
Translucent panel replacement, Velux skylights, and architectural lantern / atrium glazing. Often paired with a re-roof when the existing skylights are fatigued.
Roof penetrations
Flue stacks, exhaust vents, AC unit pads, and rooftop plant. Each penetration is a leak risk; commercial re-roofs spec each one in the quote.
Fall-arrest anchor system
Permanent anchor points (ladder access, walkway grids, edge-anchor systems) installed for ongoing roof access. Required on most commercial buildings under SA WHS — a cheap retrofit during a re-roof saves expensive scaffolding for every future maintenance visit.
Commercial gutter and box gutter
Big gutters, big consequences. Box gutter failure on a warehouse roof can take out a stockroom in a single storm. Sized correctly with overflow design and capacity for 1-in-20-year rainfall events.
Typical pricing (Adelaide)
| Project | Range |
|---|---|
| Commercial Trimdek (300–500sqm shed) | $80–$130 per sqm installed |
| Commercial Klip-Lok 406 (350–800sqm) | $110–$160 per sqm installed |
| Strata block re-roof (3-storey, ~400sqm) | $42,000–$78,000 |
| Skylight replacement (each) | $850–$2,400 |
| Box gutter (per linear metre) | $180–$320 |
| Permanent anchor system (small commercial) | $4,500–$12,000 |
| Industrial roof repair (per square / 9.3sqm) | $280–$580 |
Commercial pricing is dominated by access (crane, scissor-lift, scaffolding), staging requirements (section-by-section to keep the business open), and the volume of penetrations.
Process
- Site survey. Mandatory for jobs over 200sqm. Drone-only quoting is unreliable for commercial — we need to walk the roof, check fastener fatigue, photograph penetrations, and assess fall-arrest requirements.
- Written, itemised quote within 2–3 business days (longer than residential due to the survey work). Materials, fasteners, labour, fall-arrest setup, traffic management (where applicable), and any required certification all line-itemed.
- Variation procedure. Commercial jobs typically include a variations clause for hidden conditions (asbestos sarking discovered during strip, structural issues with battens). Variations are signed off in writing before extra work proceeds.
- Project program. For larger jobs, we provide a program — strip days, install days, completion. Coordinated with the operating business so the works minimise downtime.
- Handover. Workmanship terms as set out on the quote, manufacturer warranty registered, and fall-arrest documentation where a system is installed.
Frequently asked
Do I need to vacate during a commercial re-roof? Not usually. Most commercial re-roofs run section-by-section so the building stays operational. Loud-noise periods (sheet removal) can be scheduled out-of-hours by negotiation.
What if asbestos is discovered during the strip? Work pauses. A SafeWork SA-licensed asbestos removalist is engaged for the affected section. Variation written up; the new program reflects the additional days. The premise is closed only if SafeWork SA’s risk assessment requires it (rare for properly contained removals).
Can the strata insurance cover the re-roof? Usually no — re-roofing is capital expenditure, not an insured event. Storm-damage strata claims are a different category; see Storm Damage & Insurance Claims.
Do you do industrial low-pitch (less than 5°) roofs? Yes. Klip-Lok 406 / 700 in concealed-fix is the standard low-pitch choice for Adelaide industrial. Special attention to overflow and box gutter sizing because low-pitch holds water longer.
