What this calculator estimates

This calculator quotes the all-in installed cost for an Australian 2026 polycarbonate roof — for patio covers, pergolas, carports, lean-tos, verandahs and conservatories. It separates the bill into the line items hipages and ServiceSeeking installers actually invoice:

  • Sheet cost — Suntuf, Laserlite 3000, Palram Sunglaze, Macrolux or Stratco Cooldek-Poly sheet priced per m², scaled by sheet type (corrugated / solid / twin-wall / multi-wall), tint, storey and access.
  • Glazing bars — Stratco Suntop, Suntuf Pro snap-cap or Laserlite ProClick aluminium snap-cap bars per linear m for multi-wall and twin-wall installs.
  • Perimeter trim — F-section side closures, ridge cappings, end caps, foam closure strips and breather tape per linear m.
  • Subframe — 90×35 or 90×45 timber battens, 50×50 SHS steel battens, or aluminium snap-rafter system per m².
  • Strip-out — removing the existing failed Suntuf, Laserlite or Colorbond patio roof.
  • Council fee — building approval fee where applicable for attached patio covers.
  • Skip / tip removal — Type 2 plastic recycling skip and waste-transfer charge.
  • Weekend / public-holiday premium — 25% surcharge for evening, weekend, or expedited schedules.

A minimum call-out fee of $1,950 applies in most Australian metro markets — the labour cost of a 2-person crew, the cut-to-size logistics from Bunnings or the trade supplier, and the cap-flashing labour at the wall-to-patio transition dominate small jobs.

How to use it

  1. Measure the patio area in m². For a typical Aussie alfresco, measure the outer footprint (eave-to-eave × wall-to-eave). A 4×6 m alfresco is 24 m².
  2. Pick a sheet type — corrugated Suntuf or Laserlite 3000 for the budget end ($30-55/m² material), twin-wall 6 mm Sunglaze or Macrolux for thermal-performance builds, multi-wall 16 mm Palram Sunglaze for premium alfresco, multi-wall 25 mm for full sunrooms.
  3. Pick a tint — clear for cold-climate Tasmania and the Alps, opal/Diffuser for general-purpose alfresco, SolarSmart bronze or Solasafe for high-UV northern regions, SolarSmart Heatblocker or Solar Control IR for premium overheating-control jobs.
  4. Set storey count — single-storey for ground-level patio covers, two-storey for upper-floor balcony covers, three-storey for high-rise rooftop installations.
  5. Pick access — easy is ground-level patio with ladder access, moderate is single-storey ridge with scaffold tower, hard is cyclonic tie-down installs or rooftop crane work.
  6. Set glazing-bar length in linear m. For multi-wall sheets, plan one snap-cap bar per sheet width seam (typical sheet is 1,050-1,250 mm wide).
  7. Set perimeter trim length in linear m. Measure the outside edge of the roof plus the wall-flashing line.
  8. Toggle subframe — ON if installing new battens, OFF if installing onto an existing pergola frame.
  9. Toggle strip-out — ON if replacing failed existing sheet.
  10. Toggle add-ons — Council building approval, skip / tip, weekend / public-holiday premium.

Cost drivers

Sheet type. The dominant variable. Suntuf and Laserlite corrugated at $75-130/m² installed is the Aussie benchmark — the wave profile self-drains, the sheet self-supports across 1,200 mm batten spacing, and the screw-down install is fast. Twin-wall at 6 mm doubles the thermal performance and adds $35-50/m². Multi-wall at 16 mm Sunglaze triples thermal performance and adds $120-170/m² over corrugated. Multi-wall 25 mm five-wall is the premium spec for sunrooms at $175-250/m² over corrugated.

Glazing-bar system. Multi-wall and twin-wall sheets must be installed with an aluminium snap-cap glazing bar (Stratco Suntop, Suntuf Pro, Laserlite ProClick) that seals the sheet edge while accommodating thermal expansion (polycarbonate expands 0.065 mm per metre per °C — a 4 m sheet moves 9-12 mm between 0 °C winter and +75 °C summer surface temperature in Darwin or Brisbane). Snap-cap bars run $42-58/lm installed.

Perimeter trim, breather tape and foam closures. Every sheet edge must be sealed against insects, dust and water. The open ends of internal flutes are sealed at the bottom with adhesive aluminium tape (allowing condensation to escape downward) and at the top with vapour-tight aluminium tape. Foam closure strips fit between the corrugated sheet and the wall-flashing or ridge cap.

Subframe. A 90×35 MGP10 timber batten subframe at 1,200 mm centres runs $35-55/m². A 50×50 SHS steel batten subframe (Stratco Verandah Steel) runs $55-75/m². Stratco Outback or Pavilion steel kits (full carport with engineer’s certification) run $250-400/m² (separate from the sheet line item).

Tint and SolarSmart options. Clear sheet has 89% light transmission and is the default. Opal/diffused (Suntuf Greenhouse, Laserlite Diffuser) scatters direct sun and eliminates hotspots, +6% sheet cost. SolarSmart Bronze (Suntuf) and Solasafe (Laserlite) reduce solar heat by 35-45%, +8%. SolarSmart Heatblocker (Palram SunSky Solar Smart) rejects 65-80% of infrared heat while keeping 50-60% visible light, +18% — strongly recommended for north-facing alfresco in Brisbane, Perth and Darwin.

Building height, cyclonic tie-down and access. Single-storey ground-level installs are baseline. Two-storey work adds 15% for scaffold rigging. Three-storey or higher requires elevated work platform rental ($300-$600/day) plus rigging crew. Cyclonic zones (Queensland N3/N4, NT C1-C4) require AS 1562.3 cyclonic-class fasteners and registered structural engineer’s certificate — add $1,500-3,500 to the engineering and fixing line.

Diagnostic step-by-step

  1. Check the UV-protection layer orientation — the Suntuf / Laserlite / Sunglaze manufacturer’s printed label or sticker tells you which side faces up. Installing the sheet upside-down voids the warranty and the sheet will yellow in 3-5 years instead of 12-15.
  2. Confirm AS/NZS 4256 certification stamp — every sheet should have the AS/NZS standard number printed on the edge. No certification means uncertified import — refuse it.
  3. Check fastener type and spacing — Suntuf Pro or Laserlite ProFix Plus self-drilling Type 17 screws with EPDM washers, at 400-500 mm along the batten. Generic galvanised screws with hardened washers crack the sheet and leak.
  4. Check rafter/batten spacing against the sheet specification — Suntuf corrugated spans 1,200 mm, Sunglaze 6 mm twin-wall 700 mm, Sunglaze 16 mm multi-wall 1,000 mm, Sunglaze 25 mm multi-wall 1,200 mm.
  5. Check the minimum roof pitch — polycarbonate self-supports from 5° (1:12) minimum pitch.
  6. Check cyclonic tie-down (Queensland N3/N4, NT) — additional cyclone-class screws at 250 mm centres, structural engineer’s certificate on file.
  7. Verify drainage — sheet flutes drain freely at the lower edge into a clear gutter. Foam closures must be cleaned annually to prevent insect blockage.

Avoiding scams and overcharging

Australian patio cover installs are a frequent target for low-spec contracting:

  • Quotes that use generic screws with no EPDM washer — leak within 2 years.
  • Quotes that omit aluminium breather tape on multi-wall sheets — guaranteed algae and condensation.
  • Quotes that use the generic non-Australian sheet without AS/NZS 4256 certification — refused by Council insurers and BAL bushfire compliance.
  • Quotes for cyclonic-zone properties without a registered structural engineer’s certificate of compliance.
  • Quotes that skip wall-flashing at the house attachment — water blows under the sheet in driving rain.
  • Quotes that exceed the manufacturer’s batten span — sheet sags, ponds water and fails warranty.

Insist on an itemised quote with the sheet manufacturer and product code, the UV-layer warranty term, glazing bar manufacturer, breather tape part number, fastener manufacturer with EPDM washer rating, and a written 10-year leak warranty. Verify the contractor through hipages, Oneflare or ServiceSeeking reviews and confirm Master Builders Australia or HIA membership where applicable. Check QBCC (Queensland), Fair Trading (NSW), VBA (Victoria), CBOS (Tasmania), BUILDING DAS (NT), CBS (SA), Building Commission (WA) licence registers. For attached patio covers, confirm Council Development Application or Complying Development Certificate (CDC) is in hand before work begins.

Frequently asked questions

How much does a polycarbonate patio roof cost per m² in Australia in 2026?
Most Australian polycarbonate patios, pergolas and carports installed in 2026 price between $110 and $260 per m² all-in for the sheet, snap-cap aluminium glazing bars, perimeter trim, breather tape and a timber or steel batten subframe. Corrugated polycarbonate (Suntuf, Laserlite 3000) is the budget option at $75-130/m² installed and dominates the residential pergola market. Twin-wall 6 mm (Palram Sunglaze, Macrolux) runs $110-160/m², twin-wall 10 mm $145-210/m², multi-wall 16 mm $195-300/m² and heavy-duty 25 mm five-wall $250-380/m². A typical 4×6 m (24 m²) patio cover in Suntuf SolarSmart bronze with a 90×35 timber batten subframe ranges $3,800-$5,800 installed in 2026.

Is Laserlite better than Suntuf for an Australian patio?
Both are the dominant Australian corrugated polycarbonate brands and both are excellent. Suntuf (Palram) is a clear or coloured corrugated wave-profile sheet with an over-arching 'Solar Cool' SolarSmart heat-blocker option and a 12-year UV warranty; it uses the same Greca corrugation profile as Lysaght Custom Orb sheeting so the lap detail matches existing metal patio extensions and it is the easier sheet to mix with Colorbond on the same roof. Laserlite 3000 (Ampelite) is a 0.7-0.9 mm corrugated polycarbonate with the 'Diffuser' opal and 'Solasafe' bronze options and an 'NRG' SolarSmart equivalent; it carries a 10-year UV warranty plus a 7-year hail warranty (unique in the market); Laserlite is the engineered choice for hail-prone Melbourne, Hobart and Brisbane summer storm zones. Both are AS/NZS 4256.5 certified, both are AS 1562.3 compliant, both work with the same 90×35 timber batten or 50×50 steel batten subframe. For coastal NSW and Queensland the Laserlite hail warranty makes the difference; for inland WA, SA and NT the Suntuf SolarSmart range has the wider tint palette.
Does a polycarbonate patio cover need council approval?
It depends on the state, the size and whether it is attached to the dwelling. Free-standing pergolas under 20 m² and under 3 m height are typically permit-exempt in NSW (SEPP Codes 2008), Victoria (Building Regs 2018 Reg 87) and Queensland (Building Act 1975 Schedule 1) as 'Class 10a non-habitable structures' below the minor-works threshold. Attached patio covers (those bolted to the house) are NOT exempt — they require a Council Development Application (DA) or a private certifier's CDC under the State Environmental Planning Policy, plus full structural certification per AS 1684.2 (timber framing) or AS 4100 (steel framing) and AS/NZS 1170.2 wind-load classification. Properties in BAL-12.5 or higher bushfire zones must satisfy AS 3959 — polycarbonate sheet is acceptable to BAL-19 but bushfire-prone-area (BAL-29 and above) requires a metal roof. Cyclone zones (Queensland N3/N4, Northern Territory C1-C4) require wind-rated fixings to AS 1562.3 and a registered structural engineer's certificate of compliance.
What's the best polycarbonate tint for an Australian summer?
For most Australian climates, opal/diffused or SolarSmart bronze/tint is the right choice — clear polycarbonate transmits 89% of sunlight which makes the space underneath unbearably hot from November to March in NSW, Queensland, Victoria, SA and WA. SolarSmart Greenhouse (Suntuf) and Diffuser (Laserlite) opal sheets transmit 60-75% of light evenly without hotspots — best for relaxed entertaining areas, alfresco kitchens and pools. SolarSmart Solar Control bronze and Solasafe (Laserlite) reduce solar heat gain by 35-45% while keeping 50-65% light transmission — best for north-facing patios in Brisbane, Perth, Adelaide where summer overheating is critical. SolarSmart Heatblocker (Palram SunSky equivalent) rejects 65-80% of infrared heat while keeping 50-60% visible light — premium spec, +18% sheet cost. For Tasmania and the Victorian Alps where solar gain is welcome year-round, clear is the right call.
How long does a polycarbonate patio roof last in Australia?
Australian UV exposure is among the highest in the world (UV index 11-14 in summer across northern Australia), so polycarbonate service life is at the lower end of the global average. Premium sheet with co-extruded UV layer (Suntuf SolarSmart, Laserlite 3000 NRG, Macrolux UV-Stabilised) carries a 10-12-year manufacturer warranty against yellowing and impact loss. Real-world service life is 12-18 years in Sydney, Melbourne and Adelaide and 10-15 years in Brisbane, Perth, Darwin and Cairns where UV intensity is highest. The most common failure modes are: (1) yellowing of the upper surface after 10-12 years in tropical/subtropical regions; (2) impact damage from hail in Sydney-Melbourne-Brisbane summer storms; (3) cyclone damage in northern Queensland and NT (verify AS 1562.3 cyclonic class C/D fixings); (4) condensation pooling in multi-wall flutes from missing breather tape. Laserlite 3000 carries a unique 7-year hail warranty up to 60 mm hailstone diameter — meaningful in Sydney where 2026 BOM hail data shows 18 separate hail events exceeding 25 mm in the past 24 months.
Can I install Suntuf or Laserlite myself?
Yes — Suntuf and Laserlite are designed as DIY corrugated sheet products and the typical 4×6 m pergola is a competent two-person weekend job. Buy the manufacturer's correct fastener kit (Suntuf Pro fasteners, Laserlite ProFix Plus): self-drilling 75 mm Type 17 screws with EPDM oversize-washers, in the brand-matching colour. Pre-drill the polycarbonate at 8 mm (oversize to allow thermal expansion — never the same as the screw diameter). Screw through the crown of the corrugation, never the valley (water collects in the valley). Lap two corrugations at side laps, one corrugation at end laps. Use a foam closure strip at the eave and ridge. Maintain a minimum pitch of 5° and a maximum span of 1,200 mm between battens. For multi-wall and twin-wall sheets, the snap-cap bar system and breather tape orientation are trickier and a hipages-rated installer is recommended above 20 m².
