Commercial roofing across Melbourne
Roof Repair Melbourne VIC arranges commercial roofing quotes for buildings across Greater Melbourne: warehouses and factory units in industrial areas such as those around Dandenong, shopfronts and offices, medical and childcare buildings, and strata blocks with common-property roofs. Work includes leak investigation and repair, box gutter and sump replacement, skylight replacement, re-sheeting of rusted sections and full roof replacement, including removal of asbestos cement roofing where found. Independent local roofing contractors carry out the work after a free on-site inspection.
What makes commercial roofs different
Scale. A factory roof can be many times the area of a house roof, often with long sheet runs and low pitches. Profiles, fixings and fall all need to suit that.
Box gutters and sumps. Many commercial buildings drain to internal box gutters and sumps. When these block or rust, water ends up inside the building, often over stock or electrical equipment.
Penetrations. Exhaust fans, air-conditioning plant, skylights and vents all pierce the roof, and each is a possible leak point.
People underneath. Tenants, staff and customers need to keep working while the roof is fixed.
Safety. Large roofs bring fall risks at edges and through fragile skylights and old cement sheeting. Workplace safety duties apply to everyone involved.
Common jobs
- Tracing leaks in low-pitch roofs and replacing failed fixings and washers.
- Replacing rusted box gutters and adding or clearing overflow provisions.
- Swapping old fibreglass skylight sheets for new ones, with guarding.
- Re-sheeting sections of rusted or damaged roof.
- Full re-roofing of older factory units, sometimes including asbestos removal.
- Upgrading insulation and condensation control when the roof is replaced.
Planning around the business
A good commercial roofing quote shows how the job will be staged. Typical approaches include working one bay at a time so each section is closed in the same day, scheduling noisy work early or after hours, protecting stock with sheeting, and agreeing on access paths for materials and waste. Tell the contractor about any sensitive operations, such as food handling, medical rooms or server cabinets.
Strata and landlord buildings
For strata properties, the owners corporation usually controls common-property roofs and needs to approve quotes and access. For leased buildings, check the lease to see whether the landlord or tenant is responsible for the roof. Either way, ask for written scopes and keep the compliance documents for the building file.
Registration, safety and asbestos
Roof plumbing on commercial buildings should be done by a registered roof plumber, who issues a compliance certificate for qualifying work. Older commercial roofs may contain asbestos cement, which must be handled under WorkSafe Victoria's rules; see our asbestos removal page. We ask the contractors we work with to hold the registrations and insurance their job needs, and on a commercial site you should also ask for their safety documentation.
Getting a quote
Tell us the building type, roof size if known, the problem and any constraints on hours or access. A roofer will inspect, photograph the issues and price the work in stages where that helps. For general price context, the 2026 price guide covers residential bands only; commercial work is always priced individually.
