On a strata or commercial building, one roof leak can affect several units or a whole tenancy, and everyone wants to know when it will be fixed. We work with strata managers, building managers and owners across central Sydney, from CBD buildings with sandstone parapets to apartment blocks with box gutters and warehouses with large metal roofs.

Signs you need this

A box gutter or sump overflowing into a unit or common area
Repeat leaks into the same top-floor apartment
Rust spreading across a large metal roof
A building that hasn't had its roof inspected in years

Seeing one of these? It rarely fixes itself, and the earlier we look, the smaller the job usually is.

No obligation. We look, tell you what we find, and quote a fixed price before anything starts.

Working with strata and building managers

Strata roof work needs more than a repair. Managers need a clear account of what was wrong, which units it affected and what was done, so they can report back to the owners corporation. Every job comes with a photo report, and a fixed written quote comes before work starts, which keeps approvals simple.

We carry $20 million public liability and are fully licensed and insured for domestic, strata and commercial work. We arrange access around residents and tenants, and a person answers our phone 24/7 if a box gutter overflows at night.

Box gutters, parapets and big metal roofs

Apartment blocks and CBD buildings often drain through box gutters and sumps hidden behind parapets. When one blocks, the water has nowhere to go but inside, often into a top-floor unit or a common stairwell.

Scheduled maintenance is the cheapest protection: clearing gutters and sumps, checking flashings and fixings, and catching rust before it spreads. When repairs are needed, they're usually metal roof repairs, box gutter repairs or, on ageing sheeting, a roof replacement.

What this looks like on the roof

Photos from our own jobs: the roofs as we found them and as we left them, not stock imagery.

What this costs, honestly

Anyone who quotes you a firm price over the phone is guessing. Four things move the number, and we can only weigh them from the roof, which is why we look first, then quote a fixed price before any work starts. The inspection and the quote are free.

The size of the problem
Swapping a few cracked tiles and repointing a short run is a small job. Renewing a whole ridge line, or a valley that has rusted from end to end, takes far longer.
The roofing material
Terracotta, concrete tile, slate and metal each need different materials and skills. Finding a matching tile or slate for an older roof costs more than a modern profile that is easy to source.
Getting onto the roof
A low single-storey roof with clear side access is quick to work on. A two or three-storey terrace with no side access, a steep pitch or a neighbour's roof in the way may need scaffolding and extra time.
Hidden damage
This is the biggest variable. If water has been getting in for months, the battens, rafters or fascia may have rotted. That only shows once we're on the roof, which is why we inspect before we quote.

Common questions

Is the roof inspection and quote free?

Yes. Roof Repairs Sydney inspects the roof, photographs what it finds and gives you a fixed written quote at no cost. There is no obligation to go ahead, and you won't be pressured if you decide not to.

Is Roof Repairs Sydney open 24/7?

Yes. Roof Repairs Sydney is open 24 hours a day, seven days a week, including weekends and public holidays. A real person answers 1300 077 018 at any hour. For a leak or storm damage at night, the roof is made safe first, and the permanent repair is quoted and done once the weather is dry.

Why is my ceiling stained when the roof looks fine?

A ceiling stain is rarely directly below the leak. Rain gets in higher up, runs along the sarking, battens or rafters, and drips at the first low point, which can be metres away. That is why patching the roof straight above a stain often fails. Roof Repairs Sydney traces the water back to its real entry point before quoting a repair.

Which areas of Sydney does Roof Repairs Sydney cover?

Roof Repairs Sydney is based in Rosebery and covers central Sydney: the CBD and inner city, the Eastern Suburbs to the coast, the Inner West, the Lower North Shore, Manly, Ryde and Hunters Hill, St George and the Sutherland Shire. If your suburb isn't listed, call 1300 077 018 and ask.

Does Roof Repairs Sydney do strata and commercial roofs?

Yes. Roof Repairs Sydney works on domestic, strata and commercial roofs, including apartment blocks, offices, shops and warehouses. Common jobs are box gutter and sump repairs, leaks into top-floor units and metal roof repairs. Strata and building managers receive a photo report and a fixed written quote before work starts.

Is Roof Repairs Sydney licensed and insured?

Yes. Roof Repairs Sydney is fully licensed and insured for domestic, strata and commercial roofing work, and carries $20 million public liability cover.

Who runs Roof Repairs Sydney?

Roof Repairs Sydney is a family-run business led by Michael and Sean, with more than 30 years of experience on Sydney roofs. The business is based in Rosebery and repairs tile, metal and slate roofs on homes, strata buildings and commercial properties across central Sydney.

What types of roofs does Roof Repairs Sydney repair?

Roof Repairs Sydney repairs terracotta and concrete tile roofs, Colorbond and corrugated iron roofs, and natural slate roofs, including heritage slate on Victorian and Federation terraces. The work covers leaks, gutters and box gutters, flashings and valleys, skylights, storm damage and full roof replacement.

Does Roof Repairs Sydney offer scheduled roof maintenance?

Yes. Roof Repairs Sydney offers scheduled roof maintenance for strata and commercial buildings: clearing box gutters and sumps, checking flashings and fixings, and a written photo report the building manager can file. For houses, maintenance mostly means clearing gutters and valleys and catching failing ridge pointing before it leaks.
