Service Areas
DBZ Contracting repairs, replaces and restores roofs right across Greater Sydney — from the Eastern Suburbs and Northern Beaches to the Hills, Sutherland Shire and out to Penrith.
Bondi rooftops cop one of Sydney's harshest weather mixes — salt air off the Tasman, sustained UV, and sudden southerly busters.
Roofing in Bondi →Chatswood's mix of mid-century brick homes, 1990s townhouses and recent high-density apartments needs different roofing answers across the same postcode.
Roofing in Chatswood →Cronulla's beachfront exposure makes marine-spec roofing the default — the same salt-corrosion logic as Bondi runs the full length of the Shire coast.
Roofing in Cronulla →Hornsby and the upper North Shore sit under heavy tree canopy — gutter loading and leaf-guard work dominate the call-outs.
Roofing in Hornsby →Liverpool and the broader South West has a fast-growing mix of established post-war housing, 80s–90s estates and new-build estates — and a steady stream of builder-spec warranty work.
Roofing in Liverpool →Manly's peninsula geography means salt air across most of the suburb — and a housing stock that runs from heritage Federation through to designer architectural builds.
Roofing in Manly →Mosman's housing stock skews high-value heritage — Federation, Edwardian and Inter-War with tile and slate roofing that needs specialist knowledge.
Roofing in Mosman →Parramatta is one of Sydney's densest commercial centres — our work skews to commercial buildings, strata and large multi-residential.
Roofing in Parramatta →Penrith and the foothills carry the hottest summers in metro Sydney — material choice matters more here than almost anywhere else.
Roofing in Penrith →Sutherland proper — inland Shire — has a different material logic to coastal Cronulla. Tile dominates and tree canopy drives gutter work.
Roofing in Sutherland →Every suburb, every service: Roof Replacements · Roof Restorations · Roof Repairs · Gutters & Downpipes · Metal Pergolas & Patios · Professional Cladding

Still have a question?A new Colorbond roof on a typical 3-bedroom Sydney home costs between $9,000 and $20,000 in 2026 depending on roof size, profile choice, pitch, and whether the existing roof must be removed first. Tile-to-tile replacement runs $12,000–$22,000; tile-to-Colorbond conversions $14,000–$25,000. Final price is confirmed in a free written quote.
Yes. DBZ Contracting holds NSW Fair Trading contractor licence 000000C. You can verify the licence at verify.licence.nsw.gov.au. NSW Fair Trading requires a licensed contractor for any residential roofing work valued over $5,000.
Yes. We provide same-day response for active leaks during business hours (Mon–Sat 7am–6pm) and a 24/7 emergency phone line for after-hours storm response. Emergency call-out includes immediate make-safe and temporary tarping, with a full quote provided within 24 hours.
Roof restoration extends the life of an existing roof through cleaning, re-bedding ridges, re-pointing, and repainting — suitable when the underlying tiles or steel are still sound. Replacement removes the entire roof and installs new. Restoration typically costs 30–50% of full replacement and adds 10–15 years of service life.
Yes. We provide detailed damage assessment reports, scope of works, and liaise directly with insurers and adjusters. We recommend calling us before lodging your claim so the assessment is documented correctly from the start.
