How much does a carport cost – aluminium, steel or wood?
Two quotes for a "carport" can differ widely and both still be fair. Here is what drives the price and how to compare aluminium, steel, wood and a DIY kit.

"How much does a carport cost?" is a question no honest installer can answer with a single number without seeing the site. Two quotes for a carport of the "same" size can differ significantly and both still be correct – they simply include different things. So you will not find prices here, but something more useful: the factors that set the final figure, and how to compare quotes without comparing apples with oranges.
1. Size and number of cars
The most obvious factor is the area: a single and a double carport differ in more than square metres. A wider carport needs beams that span a bigger opening, which means stronger profiles or an extra post. If you want a wide opening with no post in the middle – handy with two cars – the structure gets heavier. If you are not sure what size you need, read our article on carport dimensions.
2. Free-standing or attached to the house
A carport fixed to the house wall uses it as a support on one side and usually needs fewer posts. A free-standing carport stands entirely on its own posts and foundations. Fixing to the wall depends on the wall itself, though: insulation, masonry and eaves height may call for special anchors or an extra beam. That can only be judged on site.
3. The material: aluminium, steel, wood or a DIY kit
- Aluminium. Does not rust, the profiles are light and are usually powder-coated in the colour you choose. The upfront price is higher than a basic steel frame, but maintenance is minimal – mostly cleaning. A good fit if you want the carport to look good for many years without repainting.
- Steel. Strong and allows wide spans, but rusts where the protection is damaged. The price depends heavily on whether the steel is galvanised, primed and painted or only painted. A cheap steel carport often turns expensive when it needs sanding and repainting after a few years.
- Wood. Warm, natural look, often a lower upfront price. Needs regular treatment and painting, and rots and warps if neglected. A good choice if you like timber and are ready to maintain it.
- DIY kit. The lowest entry price, but standard sizes, thinner profiles and you assemble it yourself. Not always designed for the snow loads in every part of Bulgaria. Suitable for small, sheltered spots, less so for a wide carport in the open.
When comparing, look not just at today's price but at what the carport will have cost after ten years – with paint, treatment, repairs and your time. For the difference between ready-made and made-to-measure structures, see also ready-made or custom pergola – the logic is the same.

4. The roof
Roofing is often the second-largest item in a quote. The main options are:
- Polycarbonate – light and lets light through, protects from rain and snow. It varies in thickness, type (multiwall or solid) and UV protection, which affects both price and lifespan.
- Sandwich panels – opaque, give full shade and better insulation. Heavier, so the structure has to carry them.
- Metal sheeting – more economical, but noisier in rain and heats the air underneath in summer.
- Glass – the cleanest look, but also the heaviest and most expensive roof. Rarely needed for a carport alone.
5. Snow and wind in your area
The carport has to withstand the snow and wind where it stands. In Ruse and the Danube plain, in Dobrudzha or in the mountains, the loads differ. Higher loads mean stronger profiles, closer beam spacing or more posts – and a higher price. This is where a cheap carport most often saves money without telling you. Ask which loads the structure is designed for.
6. Foundations and paving
The posts are fixed to concrete footings or to an existing sound concrete slab. If the spot is lawn, paving on sand or sloping, new footings are needed – a separate item that is sometimes missing from the lowest quote. Agree who digs, who pours the concrete and who restores the paving afterwards.
7. Drainage and details
A gutter and downpipe (sometimes hidden in a post) are not a luxury: without them water falls in front of the car door or onto the neighbour's side. Profile colour, side walls or ZIP screens against wind and driving rain, lighting and power also affect the price. Some clients add a side wall facing the prevailing wind or plan a socket for a future charging point – planning it now costs less than retrofitting. What is possible in your case is settled at the site visit.

8. Paperwork, access and removal
If the municipality asks for a design solution from a structural engineer, that is an extra cost – read whether you need a permit for a carport. Access matters too: difficult access for equipment, an old carport to remove or work at height over a fence add time and labour.
How to compare carport quotes
- Compare the dimensions – width, depth and clear height under the beam, not just "for two cars".
- Look at the profiles – material, cross-section and protection (powder coating, galvanising).
- Compare the roof – type, thickness and UV protection of the roofing.
- Check whether foundations, gutter, downpipe and installation are included.
- Ask about snow and wind – which loads the structure is calculated for.
- Agree who handles the paperwork if the municipality requires it.
Common mistakes that make a carport more expensive
- A carport that is too narrow or too low and turns out awkward for a bigger car a year later.
- Drainage left out, so gutters have to be added and paving repaired later.
- Cheap roofing without UV protection that yellows and becomes brittle.
- Installing without checking with the municipality, followed by costs for alterations or removal.

Frequently asked questions
How much does a carport cost?
The price depends on size, structural material, roofing, foundations, snow and wind loads in the area and extras such as gutters and side walls. That is why an exact price comes after a site visit and measurements. The free site visit gets you a quote for your specific spot.
Which is cheaper – an aluminium or a steel carport?
A basic steel carport is often cheaper upfront. Aluminium, however, does not rust or need repainting, so the gap narrows over the years. Compare maintenance costs too, not just the installation price.
Is a carport kit from a DIY store worth it?
A kit has the lowest entry price, but standard sizes and thinner profiles, and it is not always designed for the snow loads of every region. It suits small, sheltered spots. For a wide carport in the open, a made-to-measure structure is usually the safer choice.
Which carport roof is better – polycarbonate or panels?
Polycarbonate lets light through and is lighter, while sandwich panels give full shade and better insulation but are heavier. It depends on whether the carport is next to windows you do not want to darken and how hot the summer is on site. Polycarbonate should have UV protection.
What is included in the price of a carport?
This differs between companies, so always ask. Check whether foundations, drainage, installation, transport and removal of an old carport are included. A good quote lists everything separately.
