Arched carport for two cars: a complete guide to selection and installation

Protecting cars from precipitation, sun and mechanical damage is a key task for any car owner. An arched carport for two cars becomes the optimal solution when you need to combine functionality, aesthetics and space saving. Unlike traditional flat structures, arched models provide better water drainage, increased snow load and an original appearance.

In this article we will analyze all aspects of the selection and installation of arched canopies: from calculating sizes to the nuances of installing various materials. You will find out what design features affect durability, how to avoid mistakes when assembling yourself and what brands offer the best value for money in 2026. We will pay special attention to issues permitting documentation - when the canopy is considered a permanent structure and requires approval.

Advantages of arched canopies over other types

The arched shape is not just beautiful - it allows you to increase the useful height of the structure by 15-20% compared to flat analogues with the same width. This is especially important for SUV or minivan owners. Key advantages:

• 🌧️ Efficient drainage — the arched roof eliminates the accumulation of water and snow in the center, which reduces the load on the frame
• 💨 Wind resistance — streamlined shape reduces windage, which is critical for regions with strong winds
• 🚗 Versatility — suitable for cars of different heights (from sedans to crossovers) without changing the design
• 🏡 Landscape integration — soft lines visually “fit” into any yard better than angular structures

A comparative analysis shows that arched canopies require 30% less snow removal in winter compared to lean-to canopies. And due to the absence of sharp corners, they are safer for children and pets. However, there are also nuances: installation of such structures is more difficult, and the cost of materials is 10-15% higher due to the need to bend profiles.

Dimensions and layout: how to calculate a carport for 2 cars

Minimum dimensions of the canopy for two middle class cars (Sedan or Hatchback): 5.8 m wide × 6 m long. But this size does not take into account:

• 🚪 Clearance for opening doors (optional 0.8-1 m on each side)
• 🚶 Passage between cars (minimum 1 m)
• 📏 Ability to maneuver when parking (add 1.5 m to length)

For comfortable use, we recommend the following parameters:

Car type	Canopy width	Canopy length	Ridge height
2 sedans (for example, Toyota Camry)	6.5–7 m	6–6.5 m	2.5–2.8 m
Sedan + SUV (Kia Sportage)	7–7.5 m	6.5–7 m	2.8–3.2 m
2 SUVs (Hyundai Santa Fe)	7.5–8 m	7–7.5 m	3.2–3.5 m
Minibus + passenger car (Gazelle Next)	8–8.5 m	7.5–8 m	3.5–4 m

Important to consider arch angle — optimal value 25-30°. At a lower angle, snow will accumulate; at a larger angle, the windage will increase. To calculate the exact dimensions, use the formula:

Arc length (L) = π × R × α/180
where R is the radius of the arch, α is the central angle in degrees

Materials for frame and roof: comparison of characteristics

The choice of materials depends 80% durability designs. The frame is usually made from:

• 🔩 Galvanized steel (thickness 2–3 mm) - a budget option, but requires anti-corrosion treatment every 3-5 years
• 🛠️ Aluminum profile - lightweight (weight 40% less than steel), does not rust, but is 60% more expensive
• 🏗️ Wooden beam (section 100×100 mm) - environmentally friendly, but needs to be impregnated with fire and bioprotection annually

Popular for roofing:

Material	Service life	Price per m²	Pros	Cons
Polycarbonate SUNNEX (8 mm)	10–15 years	1 200–1 800 ₽	Lightweight, transmits light, flexible	Burns out in the sun, gets scratched
Corrugated sheet C21 (0.5 mm)	20–25 years	800–1 500 ₽	Durable, non-flammable, large selection of colors	Noisy when it rains, needs sheathing
Metal tiles Monterrey	30+ years	1 500–2 500 ₽	Aesthetic, reliable, corrosion resistant	Heavy, difficult installation
PVC awning Ferrari 502	5–8 years	600–1 200 ₽	Mobile, does not require a foundation	Low frost resistance (up to -20°C)

For regions with heavy snowfall (for example, Siberia) it is optimal corrugated sheeting 0.7 mm thick with sheathing pitch 30–40 cm. In the southern regions (Krasnodar Territory) it is better to choose polycarbonate with UV protection — it reduces the temperature under the canopy by 5–7°C.

How to check the quality of polycarbonate?

Press your fingernail onto the sheet: high-quality material does not press or crack. Also inspect the edge - there should be no bubbles or delaminations on the cut.

Foundation and fastening: step-by-step installation instructions

Without the right foundation, even the strongest canopy will sag in 2-3 years. The choice of foundation type depends on the soil:

• 🏖️ Sandy/sandy loam - enough spot concrete blocks (depth 40–50 cm)
• 🌳 Clay/heaving - required strip foundation below freezing level
• 💧 Swampy - only screw piles (length 1.5–2 m)

Step-by-step installation algorithm:

A critical mistake is saving on anchors. For steel frame use chemical anchors Hilti HIT-HY 70 (can withstand loads up to 2 t), for wood - galvanized screws 8×120 mm in increments 30 cm.

⚠️ Attention: If the shed is adjacent to the house, leave a gap 5–10 cm between the canopy roof and the wall. This will prevent condensation from accumulating and rotting the sheathing.

Legal nuances: is it necessary to approve the canopy?

According to Town Planning Code of the Russian Federation (Article 51), canopy area up to 50 m² does not require a building permit if it:

• 📄 Does not have a capital foundation (point supports or piles are used)
• 🏠 Not adjacent to residential premises (distance to home > 3 m)
• ⚡ Not connected to utilities (electricity, water)

However, in Moscow region, St. Petersburg and in some regions local regulations apply. For example, in Leningrad region any canopy area > 20 m² must be included in EGRN as an "auxiliary structure". To do this you will need:

1. Scheme of planning organization of a land plot (SPOZU)
2. Technical plan (cost 8 000–15 000 ₽)
3. Notification of the start of construction (submitted through the MFC)

⚠️ Attention: If the canopy covers more than 30% of the area of the land plot, it may be considered an unauthorized building. In this case, the courts often order the dismantling of the structure (Resolution of the Plenum of the RF Armed Forces No. 10 of 2019).

The cost of turnkey arched canopies in 2026

Prices vary depending on materials and complexity of the project. Current prices for Russia (including delivery and installation):

Construction type	Roof material	Turnkey price	Production time
Economy (frame made of profile pipe 40×40 mm)	Corrugated sheet C8	120 000–180 000 ₽	7–10 days
Standard (frame 60×60 mm, galvanized)	Polycarbonate 10 mm	180 000–250 000 ₽	10–14 days
Premium (aluminum frame, metal tiles)	Monterrey or Pural	300 000–500 000 ₽	14–21 days
Mobile (collapsible, PVC awning)	Ferrari 502 or Valmiera	80 000–150 000 ₽	3–5 days

Save 20–30% possible with self-assembly. For example, canopy kit 6x7 m made of polycarbonate will cost 90 000–120 000 ₽ (without foundation). But keep in mind: installation of arches requires a special tool - pipe bender or roll forming machine, whose rent costs 3,000–5,000 ₽/day.

💡

The most reliable frame manufacturers in 2026: Alpha Profile (Russia), Bungo (Japan) and ShelterLogic (USA). Their designs are certified according to GOST 30247.1-94 for snow loads up to 180 kg/m².

Operation and care: how to extend the life of your canopy

Even the most durable canopy will not last long without regular maintenance. Basic rules:

• ❄️ in winter — clear the snow with a plastic shovel (metal scratches polycarbonate). Maximum load for standard models: 100–150 kg/m²
• ☀️ Summer - wash the roof with soapy water 2 times a season. For polycarbonate, use the product Plexiglas Cleaner
• 🔧 Once a year — check the fastenings and tighten the bolts (especially after strong winds)

For metal frames, chip processing is critical. Use zinc paste Zinga or aerosol Kudo — they restore the anti-corrosion layer. Treat wooden supports once every 2 years composition Senezh Ognebio (cost 500 ₽/l).

⚠️ Attention: If the canopy is installed on screw piles, check their verticality every 3 years. Subsidence even by 2–3 cm may lead to deformation of the arches.

FAQ: answers to frequently asked questions

Do I need to get a permit if the shed is adjacent to a fence?

Yes, if the fence is border of the land plot. According to SNiP 30-02-97, the distance from the canopy to the fence must be at least 1 m. Otherwise, coordination with neighbors and changes to the boundary plan are required.

Is it possible to install a canopy on a sloped plot?

Yes, but it will be required stepped foundation or adjustable supports. Slope up to 10° compensated by different heights of racks, above 10° — additional diagonal ligaments are needed in the frame. The cost of installation on a sloping site increases by 15–25%.

Which canopy is better: arched or gable?

Arched wins by wind resistance and snow load, but loses in terms of:

• Difficulty in installation (requires bending profiles)
• Prices (10–15% more expensive than gable)
• Possibility of installing solar panels (on a curved surface, efficiency drops by 20%)

Gable awnings are cheaper and easier to assemble, but are less reliable in regions with strong winds.

How long will a polycarbonate canopy last?

Service life quality polycarbonate (SUNNEX, Polygal) — 12–15 years. But it's reduced to 5–7 years, if:

• Cheap Chinese material is used (thickness < 6 mm)
• Sheets are stacked without thermal washers (lead to warping)
• The canopy is exposed to direct sunlight without UV protection

Is it possible to attach a carport to a garage?

Yes, but you must:

1. Keep your distance 5–10 cm between the roof of the shed and the wall of the garage
2. Use flexible connecting elements (e.g. rubber gaskets)
3. Organize a separate drain for the canopy (water cannot be drained onto the garage foundation)

If the garage is heated, the adjacent shed must have heat insulation screen to avoid condensation.
