Typical Cost to Build a Deck and Roof Together in Brisbane (2026)

• Small combo (20–30 m² deck + matching roof): $15,000–$30,000
  – Often treated pine deck with single-skin non-insulated roof for budget-friendly setups.
• Medium projects (30–50 m²): $25,000–$50,000
  – Hardwood timber deck paired with insulated flyover patio roof for superior comfort and style.
• Large or premium (50 m²+ with extras): $40,000–$80,000+
  – Includes engineering for elevated/cyclonic ratings, stairs, balustrades, lighting, fans, and custom details.

For context: A standalone 6m x 4m (24 m²) hardwood timber deck might start at $12,000–$15,000, while adding a flyover insulated patio roof could add $6,600–$7,800+, bringing the total combo into the $20,000–$25,000 range for many homes.

Key Factors That Influence Your Deck + Roof Cost

Every project is unique due to site conditions, council rules, and personal choices. Here are the main drivers of price:

1. Size (Square Metres)
   Larger areas require more materials, framing, posts, and beams—costs scale directly with m².
2. Deck Materials
   – Treated Pine: ~$200–$250/m² installed — affordable and reliable for ground-level.
   – Hardwood (Merbau, Spotted Gum): ~$320–$350/m² — durable, termite-resistant, beautiful natural finish.
   – Composite: ~$350–$500/m² — low-maintenance, long-lasting, eco options.
   Premium boards increase upfront cost but reduce long-term upkeep.
3. Roof Type & Materials
   DeKing uses high-quality systems like Ausdeck single-skin (V-Line) for non-insulated or insulated panels.
   – Non-insulated single-skin: More economical, great airflow.
   – Insulated: Cooler summers, quieter rain, reduced heat—adds value in Brisbane’s climate.
   Flyover (raised) designs offer extra height/ventilation; attached/skillion suit specific homes.
4. Height & Elevation
   Ground-level: Cheaper footings.
   Elevated/upper-level: Needs deeper stumps, engineering, mandatory balustrades (>1m height), stairs—adds $5,000–$15,000+.
5. Site Preparation & Conditions
   Sloping blocks, clay soils, termite zones, poor access, or existing surfaces require excavation, retaining, or special footings—big variable in Brisbane.
6. Engineering, Compliance & Permits
   Must meet QLD Building Code and cyclonic wind ratings. Certification, approvals add $1,000–$5,000 depending on complexity.
7. Extras & Finishes
   Stairs, handrails/balustrades (glass/wire/timber), fascia, hidden fixings, LED lighting, ceiling fans, mitred corners—can significantly increase totals (up to $1,000/m² for fully loaded projects).
8. Professional Installation & Labour
   DeKing’s experienced team includes 25-year structural warranties. Pros ensure safety/compliance—most owners choose this over DIY risks.
9. Location & Other Variables
   Inner Brisbane access challenges or outer suburbs travel; stricter cyclone rules in some areas.
