Commercial Roof Repairs Melbourne and Victoria

Complete Commercial Roof Repair Services

Commercial roofs are complex, multi-layered systems. A single leak can stem from a variety of sources, including degraded fasteners, split flashings, blocked box gutters, or poor pipe penetrations. At Total Roof Maintenance VIC, we do not believe in quick silicone patches that fail after the next rain. We use systematic, non-invasive diagnostic techniques to find the true source of a leak and execute a permanent, guaranteed repair.

With over 30 years of experience, our qualified roof plumbers service offices, retail plazas, schools, and multi-tenant commercial buildings across Melbourne. We coordinate with facility managers, tenants, and builders to carry out repairs with minimal disruption to your daily operations.

Reactive call-outs are the most expensive way to manage an industrial roof. Once a leak occurs, it has already damaged plaster, threatened machinery and compromised stock. Total Roof Maintenance provides custom Planned Maintenance Programmes designed to identify and fix minor defects before they escalate.

we specialise in high-capacity industrial roof care for factories, warehouses and logistics complexes. Our systematic inspections, gutter clearing, and fastener audits extend the service life of your metal roof assets, protect building structures and ensure structural warranties remain valid.

Gutter Cleaning and Maintenance

Blocked gutters are a primary cause of overflow, ponding and internal water damage. Our commercial gutter cleaning service utilises high-powered, truck-mounted vacuum systems to clear leaves, silt, and debris from eaves gutters, valley gutters and downpipes.

• We clear all gutter debris, sumps, and rainheads.

• We provide a complete photographic log of the gutters before and after cleaning.

• We identify rusting areas, loose brackets, and potential overflow risks during our visit. For properties requiring regular clearing, we recommend reviewing our Industrial Roof Maintenance programmes.

Box Gutters and Downpipes

Box gutters on commercial buildings must handle high volumes of stormwater. Aging, undersized or poorly designed sumps and sumpholes can cause water to back up into the building envelope.

• We design and install custom Colorbond® and Zincalume® stainless steel box gutters.

• We upgrade sumps, rainheads, and install overflow pipes to meet AS/NZS 3500.3 plumbing standards.

• We replace damaged, rusted or undersized downpipes with high-capacity alternatives.

Roof Pitch, Re-Falling & Pooling Rectification

Standing water is the ultimate enemy of flat and low-slope commercial metal roofs. Our qualified team identifies structural deflection, corrects drainage falls, and eliminates low points to ensure rapid water shedding.

• We identify and remove persistent ponding zones that accelerate rust and degrade your roof sheets.

• We adjust your roof pitch and reinforce sagging purlins to restore optimal stormwater drainage and correct structural falls.

• We prevent long-term pooling damage, safeguarding your building envelope from major leaks.

Wall Cladding and Flashings

Weathertightness is not just about the roof. Damaged metal wall cladding and failing flashings can allow heavy cross-winds to push rain into the structure of your building.

• We repair and replace damaged architectural wall cladding (including custom profiles).

• We install and repair ridge cappings, barge cappings, apron flashings, and parapet flashings.

• We replace dried out or weathered sealants and rubber dektites on pipe penetrations.

Skylight Replacement

Old, yellowed, and cracked fibreglass skylight sheets are a common source of leaks, and reduce the amount of natural light which enters a factory making it appear darker and requiring more electrical equipment to brighten the inside. They also represent a significant safety hazard for anyone walking on the roof.

• We replace brittle fibreglass skylights with high-impact, UV-stabilised polycarbonate sheets.

• Every skylight sheet replacement is installed with compulsory safety mesh underneath.

• New skylights reduce energy costs by maximising natural daylight in warehouses and retail spaces.

Roof Vents and Access Hatches

Proper roof ventilation and secure, safe access are essential for any commercial building. We supply and install specialised vents and access hardware.

• We install high-capacity whirlybird ventilators and static ridge vents to reduce roof cavity heat and condensation.

• We install lockable, weathertight roof access hatches with safe ladders for facility technicians.

• We replace aged, leaking penetration seals around mechanical exhausts, air conditioning ducts and plumbing vents.

Thermal Imaging Leak Detection

Tracking a roof leak to its entry point can be difficult, as water often travels along structural purlins and beams before dripping into the ceiling. We use non-invasive FLIR thermal imaging cameras to see what the naked eye cannot.

• Thermal cameras locate pockets of wet insulation and moisture trapped beneath roof membranes.

• We provide clear, objective thermal reports for property owners, body corporates and insurance adjusters.

• This technology eliminates guesswork, reduces diagnostic time and saves on repair costs.

Roof Condition and Damage Reports

Whether you are planning capital expenditure, negotiating a commercial lease or lodging an insurance claim after a storm, we provide independent, expert reporting.

• We perform comprehensive roof audits, detailing every defect, rust patch, and gutter restriction.

• Our reports include a numbered photographic schedule, priority ranking (urgent vs. long-term) and clear budgets.

• We assist in insurance claims by providing structured, code-compliant scopes of work.
