Carport: Protecting your car with your own hands

Car owners who do not have a major garage often face the need to protect transport from aggressive environmental factors. Scorching sun, hail, heavy precipitation and falling leaves can cause significant damage to the paintwork and body elements. Carport becomes the optimal solution that allows you to maintain the presentable appearance of the machine and extend its service life without the construction of a full-fledged structure.

The modern market offers many options: from lightweight awning structures to massive structures made of polycarbonate and profnastile. The choice of a specific type depends on the budget, area of the site and climatic conditions of the region. Properly designed roof Not only will it shelter from rain, but it will also provide natural ventilation, preventing condensation from forming, which is more dangerous to metal than street precipitation.

In this article, we will analyze in detail the technological nuances, help you choose materials and avoid typical mistakes during construction. You will learn how to calculate the load on the supports and what type of roof is suitable for your case. The optimal height of the canopy for passenger cars is 2.3-2.5 meters, which provides free access and ventilation.

Advantages of open parking over a major garage

Many car owners mistakenly believe that only a closed box can protect the car. However, capital-garage It is often a source of problems due to lack of ventilation. In a confined space, moisture accumulates, evaporated from wet snow or a washed machine, which leads to accelerated corrosion of the metal.

The open canopy lacks this drawback. Through ventilation allows the body to dry quickly after rain or washing. In addition, the cost of construction of such a structure is much lower, and the installation time is calculated in days, not months.

It is also important to note the legal aspect. Sheds. They are often classified as non-capital buildings, which simplifies the process of coordination with local administrations and does not require a complex commissioning procedure, unlike capital buildings with foundations.

• 🚗 Cost savings: the cost of materials and works is 3-4 times lower than the construction of a garage.
• 🌬️ Natural ventilation: eliminates the formation of rust due to dampness.
• 🏗️ Installation speed: the finished structure is assembled in 2-3 days.
• 📉 No shrinkage: A lightweight roof does not require a massive foundation.

⚠️ Attention! Despite its simplicity, the design must withstand the snow load of your region. Ignoring this parameter can lead to the collapse of the roof in the first winter.

It is also worth mentioning the universality of the use of space. Under the canopy you can not only store the car, but also organize a zone for repair, washing or summer rest. The mobility of some types of canopies allows you to dismantle and move them to another place if necessary.

Selection of design: single-slip, gable or arched

The geometry of the roof is a key factor influencing the aesthetics and functionality of the parking lot. Single-pitched sheds They are the most common due to the ease of calculation and installation. They are ideal for attaching to the wall of a house or fence, providing efficient water flow to one side.

Gable structures (classic house) are often chosen for freestanding objects in windy areas. This shape better resists snow loads and wind pressure, but requires a more complex truss system and precise alignment of supports.

Arched canopies made of polycarbonate look the most aesthetically and modern. The curved shape promotes self-cleaning from snow and debris, and minimizes wind resistance. However, the installation of arc-shaped farms requires special equipment or custom elements.

When choosing a form, also consider the catchment area. The larger the roof area, the more powerful the drainage system should be. Storm sewerage Or a well-organized drainage system will prevent the formation of puddles and dirt under the car.

Materials for frame and roof: comparison and characteristics

The durability of the canopy depends on the selected materials. For the frame, a profiled pipe, wood or combined solutions are most often used. The roofing should be light but strong.

Below is a comparative table of popular materials, which will help determine the choice:

Materials	Duration of service (years)	Structural weight	Cost
Fresh-natil	20-30	Lightweight	Low.
Polycarbonate	10-15	Very light.	Medium
Metal tile	30-50	Medium.	Tall.
Soft roofing	15-20	Medium.	Medium
slate	25-30	Heavy.	Low.

Profiled sheet (profencing) - the leader in popularity due to the availability and ease of installation. It does not require a solid crate, a rather rare step of runs. However, during rain, such material creates a strong noise, which can be uncomfortable if the canopy adjoins the bedroom windows.

Polycarbonate (cellular or monolithic) lets light through, creating a bright parking area without the need for additional lighting during the day. Monolithic polycarbonate in strength is not inferior to glass, but weighs much less. The cellular option is cheaper, but less durable.

⚠️ Attention! Cheap polycarbonate without UV protection turns yellow and becomes brittle after 2-3 years. Always check for a protective film on the front of the sheet.

Step-by-step instruction: construction of a frame from a metal profile

Construction of the canopy begins with the marking of the territory and preparation of the base. Even a lightweight design requires reliable support so that it does not skew over time. Metal frame is the most reliable and durable solution.

The first step is to install the support pillars. For this purpose, holes with a depth of 80-100 cm are drilled (below the level of freezing of the soil). The pillars are vertically mounted, concreted and bound around the perimeter with a lower bandage.

Next is the assembly of farms - the bearing elements of the roof. They can be welded on the ground and raised in ready-made blocks or collected "on weight", which requires a highly qualified welder. The step of the farms is usually 1-1.5 meters depending on the snow load.

For the connection of elements used electroarc welding. After completion of welding work, all seams are cleaned, the structure is degreased and covered with a primer on metal. This is a critical step in protecting metal-frame from corrosion.

Procedure for welding:
1. Clean the metal to shine (angular grinding machine).
2. Perform the grips at several points.
3. Check geometry and levels.
4. Boil the stitches completely.
5. Clean the slag and cover with anticor.

Finish painting is performed after the roof is installed so as not to damage the coating when laying sheets. Alkyd or acrylic enamels are used for outdoor work, resistant to sunburn.

Installation of roofing and drainage

The roofing is the final stage of construction. The technology depends on the material chosen. For flooring and metal roofing, special roof screws with rubber seals are used.

Mount the sheets should be in the lower wave, strictly perpendicular to the surface. It is impossible to pull screws - this will damage the seal, it is also dangerous to not twist, since there will be a gap for moisture. Step of attachment It usually comes in one wave.

Pay special attention to the organization of water flow. Water-drainage system It can be organized in two ways: organized (through gutters and pipes) and unorganized (just flowing from the edge of the roof). The first option is preferable, since water does not pour on the head when leaving the car and does not blur the soil around the supports.

Nuances of work with polycarbonate

When installing cellular polycarbonate, it is important to correctly orient the sheets: the side with UV protection should look up. If you mix the sides, the material will collapse in one season. Also, the ends of the sheets are necessarily closed with special profiles and vapor permeable tape so that insects do not infuse inside the cells and moisture does not accumulate.

If you use polycarbonate, the joints of the sheets are connected by connecting profiles, and the edges are closed by end slats. This ensures tightness and aesthetic appearance.

Budgeting and savings in construction

The cost of the canopy varies widely. The price is affected by the size, type of materials and the availability of a foundation. You can save a lot if you do the work yourself and buy materials in the off-season.

The main items of expenditure: materials for the frame (30-40%), roofing (30-40%), concrete and consumables (10-15%), tools and delivery. Buying used materials or residues in warehouses can reduce the budget by 20-30%.

• 💰 The frame of the timber is cheaper than metal, but requires regular treatment with an antiseptic.
• 💰 Flooring is cheaper than metal roofing and easier to install.
• 💰 Self-concreting pillars saves money on special equipment.

Do not save on the thickness of metal for racks. The optimal cross-section of the profile pipe for racks up to 3 meters high is 80x80 mm or 100x100 mm with a wall of 3-4 mm. Thin-walled pipes can deform under the weight of snow or in strong winds.

⚠️ Attention! Savings on anti-corrosion treatment of metal is a false saving. Rust can destroy a cheap canopy in 5-7 years, while high-quality metal lasts 20-30 years.

Frequently Asked Questions (FAQ)

Do I need a permit to build a carport?

In most cases, light non-capital structures (without deep foundations and communications) do not require a permit. However, if the canopy is adjacent to the house or close to the border of the site, it is better to clarify local regulations (SNIP) and building rules in the administration to avoid problems with neighbors.

What is the best roof slope?

For profnatsil minimum angle is 8-12 degrees, for metal roofing - from 14 degrees. Polycarbonate can be mounted with almost any slope, but for effective self-cleaning of dirt, it is recommended to do at least 10-15 degrees.

Can I make a carport entirely out of wood?

Yes, wooden timber (100x100 mm or more) is a great alternative to metal. The tree is ecologically friendly and beautiful, but requires mandatory treatment with flame protection and regular care (painting once every 2-3 years).

How to calculate the snow load?

The snow load depends on the region. In the middle of Russia, it is about 180 kg / m2, in the northern regions it can reach 300 kg / m2 and higher. When calculating the step of the farms and the cross-section of pipes, use the data from SNiP 2.01.07-85* for your area.
