Full Roof Replacement in Hobart, TAS: Cost, Timeline & Process Guide

A full roof replacement in Hobart typically costs between A$12,000 and A$35,000, depending on roof size, material choice, and structural complexity. Most Hobart homes require 200–400 square metres of roofing material, with costs ranging from A$60–A$150 per square metre installed.

Colorbond steel is the most popular choice in Tasmania, offering durability against coastal weather and typically costing A$80–A$120 per square metre. Tile replacements are more expensive at A$100–A$150 per square metre but provide superior longevity. Asphalt shingles, less common in Hobart due to climate considerations, cost A$70–A$100 per square metre.

Additional costs to budget for include roof inspection (A$300–A$600), removal and disposal of old materials (A$1,500–A$3,500), underlayment and flashing (A$2,000–A$4,000), and guttering repairs or replacement (A$1,000–A$3,000). Many Hobart homeowners find that their building insurance excess applies when claiming for storm damage, so factor this into your overall budget.

Understanding the replacement timeline helps you prepare for disruptions and plan accordingly. The entire process typically takes 5–14 days depending on weather and roof complexity.

**Day 1–2: Inspection & Preparation.** A certified Hobart roofer inspects the existing roof, checks structural integrity, and sets up safety barriers and tarps. Your house will be assessed for any underlying damage, water ingress, or timber rot that needs addressing before new material installation.

**Day 2–3: Removal.** The old roofing material is carefully stripped and disposed of. Flashing, guttering, and underlayment are removed. Roofers check timber structure and replace any rotted battens (common in older Hobart homes exposed to moisture).

**Day 4–5: Structural & Underlayment Work.** If needed, roof structure is reinforced. New underlayment (breathable membrane) is installed to manage moisture in Tasmania's humid climate. Flashings around chimneys, vents, and valleys are installed or replaced.

**Day 6–12: Material Installation.** New roofing material is installed from bottom to top, with proper overlap and fastening. Colorbond steel is typically screwed and sealed; tiles are mortared and nailed; other materials follow manufacturer specifications.

**Day 13–14: Finishing & Cleanup.** Guttering is reinstalled or repaired, ridge capping is sealed, and all debris is removed. The roofer performs a final inspection and provides documentation for insurance claims and building records.

Most roof replacements in Hobart do not require a building permit if they use the same material and don't alter structural dimensions. However, if your replacement involves structural changes, increases roof pitch, or adds significant weight, you'll need approval from the Hobart City Council or your local Tasmanian authority.

All work must comply with the National Construction Code and meet Tasmanian Building Standards. Wind load requirements are strict in Hobart due to coastal exposure—fastening standards are higher than inland areas. If your home is heritage-listed or in a conservation area, check with your local council before proceeding, as restrictions may apply to material colour and style.

Most reputable Hobart roofers handle permit applications and inspections as part of their service. Ask your contractor whether permits are included in the quote and confirm insurance coverage for the duration of work.

If storm damage, hail, or falling debris caused your roof failure, your building insurance may cover replacement costs minus your excess. In Tasmania, building insurance excess typically ranges from A$250 to A$2,000 depending on your policy.

To make a claim: document damage with photos and video, contact your insurer immediately, obtain a damage assessment from a licensed surveyor or roofer (A$400–A$800), and submit your claim with quotes from at least two Hobart contractors. Your insurer may require that you use an approved repairer or may issue payment after inspection.

Note that wear-and-tear or gradual deterioration is not covered; only sudden, insurable events qualify. If your roof is old (15+ years) and unrelated damage occurred, insurers may offer partial replacement costs or place a depreciation clause on payouts. Always read your Product Disclosure Statement and discuss coverage limits with your insurer before proceeding.

Selecting a qualified, insured roofer is critical for quality results and warranty protection. Verify that any contractor holds a current Tasmanian building license, carries public liability insurance (minimum A$10 million), and provides a written quote detailing materials, labour, timeline, and warranty terms.

Request references from recent Hobart projects, ask about warranty length (typically 5–10 years on labour, 25–50 years on materials), and confirm whether they're registered with the Australian Roofing Association. Avoid contractors who demand upfront payment; most reputable firms accept 30–50% deposit with final payment upon completion and inspection. Compare at least three quotes before deciding, and be cautious of prices significantly below market rate—quality roofing requires skilled labour and quality materials.
