Stratco carports are steel-framed carport kits and custom builds sold by an Australian manufacturer, available in flat, skillion, gable and cantilever styles for single and double cars. They suit most Sydney homes because the kits are engineered to Australian conditions, but wind rating, council rules and site levels still decide what you can build.
Below you’ll find the main designs, kit and DIY options, roof materials, indicative costs and the mistakes that cause failed approvals and leaky roofs.
Key points
- Flat and skillion roofs look modern and cost less, while gable roofs shed water better and suit traditional homes.
- Free standing and attached carports follow different rules, and attached ones often face stricter fire and flashing requirements.
- A kit is only cheaper if the slab, levels, stormwater and approvals are sorted, so budget for those up front.
- Polycarbonate carport roofing needs at least a 5 degree pitch, and typical installed patio roofs run about $220–$360 per m².
What are Stratco carports?
They are kit or custom steel carports with a roof, posts and beams designed to bolt together on a slab or footings.
| Term | What it means | Why it matters |
|---|---|---|
| Carport kit | Pre-cut frame, roofing and fixings supplied as a package | Cheaper than fully custom, but you manage site work |
| Skillion roof carport | Single-slope roof falling in one direction | Simple, modern and easy to drain |
| Flat roof carport | Low-slope roof with a small fall | Clean lines, but needs correct fall to avoid ponding |
| Gable carport | Two-slope roof with a central ridge | Sheds water and suits traditional homes |
| Cantilever carport | Roof supported from one side only | Gives open access, but needs heavier footings |
| Attached carport | Fixed to the house wall or roofline | Needs flashing, fire and approval checks |

Stratco carports vs other metal carport kits
A metal carport kit can come from several suppliers, so compare what is actually in the box.
| Option | Good for | Check before buying |
|---|---|---|
| Steel carport kit (Stratco or similar) | Strength, wind rating and Colorbond finishes | Wind region rating and engineering certificate |
| Car port kit, DIY-only | Lower cost where you can build competently | Footings, slab, tools and council sign-off |
| Carport DIY kit with installation | People who want a kit but not the labour | Whether installation, slab and drainage are included |
| Carport aluminium | Light weight and rust resistance near the coast | Span limits and wind loading |
| Fully custom carport | Odd sites, large spans and matched designs | Engineering and design costs |
| Standalone carport with side screens | Weather protection for cars and storage | Whether it then counts as an enclosed building |
Flat roof and skillion roof carports
These are the most popular modern styles, and drainage details matter more than the look.
- Choose a skillion roof carport when you want a modern look with a simple fall to one gutter, which also keeps the roof easy to flash.
- Specify the fall on flat roof carport kits, because a roof that is too flat holds water and leaks at the laps.
- Look at flat roof steel carport plans that show footings, beam sizes and fall, and ask for the engineer’s certificate before you order.
- Consider a modern flat roof carport with matching fascia and gutters in the same Colorbond colour as the house.
- Treat a flat roof carport with deck on top as an engineered structure; it needs a structural engineer, proper waterproofing and a certifier.
- Browse flat roof carport designs that include a fall of at least a few degrees, and check polycarbonate options need a 5 degree minimum pitch.
Gable carports and double carport kits
Gable roofs shed rain well and give extra height under the ridge, which suits 4WDs and roof racks.
- Pick a single gable carport when you want a traditional look over one car space and a slightly steeper roof pitch than a flat design.
- Price a double carport kit with a gable roof against a flat roof alternative, because gable roofs need more material but add headroom.
- Allow clear width between posts so doors open fully; a compact 3×3 carport only works for small cars and bikes.
- Check carport spaces before buying, since the stated size for one or two cars may not include door-opening room.
- Match the roof pitch to the home so the carport looks designed with the house, not stuck onto it.
- Ask about insulated carport roof panels if the carport will double as a workshop, since they reduce heat and noise from above.
Free standing carports vs attached carports
| Type | Pros | Cons |
|---|---|---|
| Free standing carports | Simple flashing, flexible placement, easier to approve | Needs four posts and its own footings |
| Standalone carport at the side of the house | Keeps the house wall clear | Can block side access |
| Attached carport | Uses the house for support and weather cover | Flashing and fire separation need care |
| Front carport | Short walk to the door | Street setback and character rules may apply |
| Cantilever carport | No front posts, easy parking | Larger footings and engineering |
| Flyover carport | Matches the roofline above | More complex; see our flyover patio roof guide |
Free standing designs vary widely, so ask to see a similar one of Stratco carports or another brand built before you commit.
Carport roofing options for Stratco carports
- Use Colorbond roofing for strength and colour matching; see our Colorbond carport guide for colours and profiles.
- Use polycarbonate sheet where you want light, keeping to a 5 degree minimum pitch, which is about 88 mm of fall per metre.
- Keep corrugated polycarbonate purlin spacing within 800 mm at the ends and 1000 mm mid span, as the Laserlite data requires.
- Use only the brand’s fixings on Laserlite 2000 or 3000, because non-Laserlite fixings void the lifetime warranty.
- Choose a light tint over cars, as clear sheets cook paintwork and interiors on summer afternoons.
- Consider insulated panels for workshop carports, and compare them with a louvre roof if you also want adjustable shade.

Carport design plans and approvals
- Draw the site with boundaries, easements, trees, levels and the house, so the design plan shows where the carport can actually fit.
- Check setbacks and overlays for heritage, bushfire and flood; these can limit size, materials and distance from boundaries.
- Ask for engineering showing wind region, footings and beam sizes, and keep the certificate with your records.
- Confirm if approval is needed with your council or a private certifier, since exemptions are limited and differ between sites.
- Plan stormwater to an approved connection so runoff does not flood a neighbour or undermine the slab.
- Book licensed trades for concrete, roofing and any electrical work such as lighting or an EV charger.
Common mistakes to avoid
- Buying a kit before checking council rules, setbacks and bushfire requirements for your block.
- Pouring a slab without enough fall or footings that suit the carport’s wind rating.
- Skipping flashing where an attached carport meets the house, which causes leaks and rot in the wall behind.
- Using a roof pitch that is too flat for the sheeting, especially with polycarbonate or corrugated profiles.
- Planning a deck on top of a carport without a structural engineer, waterproofing and certifier sign-off.
- Forgetting that car doors, roof racks and 4WD height need more clearance than the plan shows.
Stratco carports FAQs
Are Stratco carports good value?
They can be, if you compare what is included. A kit price often excludes slab, drainage, installation and approvals, which add significantly to the total. Get itemised quotes for the kit, a custom build and a local installer, then compare the complete cost and warranty terms.
Can I build a carport myself from a DIY kit?
You can if you are competent, the kit suits your wind region and approvals are in place. The slab, levels and stormwater are where most DIY problems start. Electrical work such as lighting or EV charging must be done by a licensed electrician.
What is the best roof for a flat roof carport?
Colorbond steel sheeting is the usual choice for strength and low maintenance, with enough fall to drain water. Polycarbonate suits lighter, brighter carports but needs at least a 5 degree pitch. Check the sheet maker’s span rules and ask for the engineer’s details.
Do free standing carports need council approval?
Often small ones can be built as exempt or complying development, but size, location, bushfire rating, heritage and flood overlays can change that. Check with your council or a private certifier before you order, and keep the written advice with your quote.
