The choice of roofing covering often becomes the decisive factor determining the final budget of the entire construction, so the question of how to cover a roof cheaply arises before anyone who is planning to build a house or garage with a limited supply of funds. Saving at this stage should not become an end in itself, leading to frequent repairs, but finding the optimal balance between price, durability and aesthetics is an absolutely justified step for a rational developer. The market offers several time-tested options that can significantly reduce costs without critically compromising the performance characteristics of the structure.
When designing a roof, it is important to consider not only the cost per square meter of the material itself, but also the costs of lathing, fasteners, waterproofing and the complexity of installation work, which may vary depending on the type of coating. Budget roofing requires careful calculation of the slope angle of the slopes, since some cheap materials have strict restrictions on the minimum degree of slope for effective drainage. Ignoring these technical nuances can lead to leaks already in the first season of operation, which will negate all initial savings.
Modern technologies have made it possible to significantly improve the characteristics of available materials, making them more resistant to ultraviolet radiation, temperature changes and mechanical stress. Polymer coatings and modified bitumens today last significantly longer than their counterparts of twenty years ago, giving homeowners the opportunity to choose a durable solution even on a modest budget. In this review, we will analyze in detail the main contenders in the economy segment market so that you can make an informed decision.
Ruberoid and bitumen-polymer built-up materials
The traditional answer to the question of how to cover a roof as cheaply as possible remains roofing felt and its modern modifications, such as roofing felt RPP and RCP. This material has been used for decades to cover flat roofs and low pitched roofs, demonstrating acceptable reliability when installed correctly. A base of roofing cardboard impregnated with bitumen provides basic waterproofing, although it is inferior in strength to more expensive fiberglass-based counterparts.
To increase durability and aesthetic properties, today they often use euroruberoid, which is characterized by the presence of polymer additives and a denser base. The materials to be deposited require the use of a gas burner to heat the lower bitumen layer, which ensures the solidity of the coating and the absence of through holes from fasteners. However, this installation method requires certain skills and compliance with safety precautions when working with open fire.
⚠️ Attention: When using roofing felt on pitched roofs, the angle of inclination must be at least 15-20 degrees, otherwise there is a high probability of water stagnation and rapid destruction of the bitumen layer under the influence of moisture.
A significant advantage of bituminous materials is their ability to self-heal small cracks under the influence of solar heat, which extends the service life of the coating. However, roofing cardboard is susceptible to rotting, and bitumen can “float” in the heat, creating a characteristic odor and losing its shape if a special topping is not used. For temporary buildings, garages or utility rooms, this is still one of the most affordable options on the market.
- ✅ Low cost per square meter and availability in any hardware store.
- ✅ High elasticity, allowing the material to be used on complex geometric shapes.
- ✅ Excellent waterproofing with continuous installation and no mechanical damage.
- ❌ Relatively short service life (5-10 years for regular roofing material) compared to other materials.
Classic and Euroslate: timeless classics of economy class
Asbestos-cement slate for many years it remained the uncontested leader in the segment of inexpensive roofing, and even today it does not lose ground due to its strength and fire resistance. Corrugated sheets reinforced with a cement matrix can withstand significant snow loads and do not burn, which makes them popular for country houses and cottages. Despite debates surrounding the environmental friendliness of asbestos, modern certified slate is considered safe for use in residential construction.
An alternative to the traditional option is euroslate (ondulin), which is made from cellulose fibers impregnated with bitumen. This material is much lighter than its classic counterpart, which allows you to save on the rafter system and makes it easier to lift sheets to a height. Bitumen corrugated sheets They are easy to cut with a regular knife, do not require special tools and can be laid on top of an old roof, which is important during repairs.
However, slate has its limitations: it requires fairly frequent lathing and careful handling during installation, as it is a fragile material. Nails for fastening must be driven strictly into the crest of the wave through special gaskets to avoid leaks in the future. Over time, moss and lichen may appear on the surface of the slate, especially in shaded areas, which requires periodic cleaning or treatment with special compounds.
| Parameter | Asbestos cement slate | Euroslate (Ondulin) | Metal slate |
|---|---|---|---|
| Weight 1 m² | 14-16 kg | 3-4 kg | 4-5 kg |
| Service life | 30-40 years | 10-15 years | 20-30 years |
| Flammability | Doesn't light up | Flammable | Doesn't light up |
| Noise insulation | High | Very high | Low (requires insulation) |
Metal tiles and corrugated sheets: durability at an affordable price
If we consider the ratio of price and service life, then corrugated sheet and metal tiles occupy a leading position in the budget segment. These materials are steel sheets with a zinc coating and a protective polymer layer, profiled to provide rigidity and an aesthetic appearance. The difference between them lies only in the shape of the profile: corrugated sheeting has a simple wavy or trapezoidal shape, and metal tiles imitate the relief of natural tiles.
The main advantage of a metal roof is its high mechanical strength and ability to withstand extreme weather conditions, including hail and hurricane winds. Polymer coating (polyester, pural, plastisol) protects steel from corrosion and fading, ensuring the preservation of its appearance for decades. With proper installation and the use of high-quality self-tapping screws with EPDM seals, such a roof can last more than 50 years.
To save your budget, choose metal tiles coated with polyester (PE) 25 microns thick - this is the most affordable and proven option for private homes in temperate climates.
An important aspect when choosing a metal is the thickness of the steel sheet and the quality of galvanizing, which directly affect corrosion resistance. Cheap options often have a thin layer of zinc and steel less than 0.4 mm thick, which can lead to rust after just a few years of use. It is recommended to pay attention to products from well-known manufacturers that provide a guarantee against through corrosion.
⚠️ Attention: Metal roofing has high thermal conductivity and resonating ability, and therefore requires the mandatory installation of soundproofing materials and high-quality ventilation of the under-roof space.
Seam roofing made of galvanized steel
Seam roofing made of thin-sheet galvanized steel is one of the most airtight types of coatings, where the sheets are joined by twisting the edges (folds), which eliminates the use of through fasteners on the slope plane. This makes this option ideal for roofs with complex geometries and low slopes where other materials may not be effective. The absence of holes on the work surface minimizes the risk of leaks.
Despite the apparent simplicity of the material, installation of seam roofing requires highly qualified workers and the use of special equipment, which can increase the cost of the work. However, if the task is to cover the roof cheaply and cheerfully, using simple galvanization without a polymer coating, then this is one of the most budget options for the price of raw materials. Such a roof will patina over time, becoming covered with a protective oxide film, which prolongs its life.
Modern technologies make it possible to use aluzinc (steel coated with aluminum and zinc), which is significantly more corrosion resistant than regular zinc. This coating lasts 2-3 times longer than standard galvanizing, while remaining in an affordable price segment. This is an excellent solution for temporary buildings or unheated facilities.
- ✅ Maximum tightness thanks to hidden fasteners and the absence of through holes.
- ✅ Possibility of laying on slopes with a minimum slope (from 3-5 degrees).
- ✅ The lightness of the material reduces the load on the load-bearing structures of the building.
- ❌ High requirements for the qualifications of installers and the complexity of self-installation.
Flexible tiles: a compromise between price and quality
Bituminous shingles (soft roofing) is a fiberglass material impregnated with modified bitumen and covered with basalt topping. This material combines the waterproofing properties of roofing felt and the aesthetic appeal of natural tiles. The flexibility of shingles allows you to cover roofs of any complexity, including domes and turrets, without waste, which often happens when working with sheet materials.
The economy segment features series with a simple pattern (for example, “petal” or “square”) and a standard set of colors. Self-sealing layer on the inside of the shingles provides additional sealing under the influence of solar heat, turning the roof into a monolithic carpet. The service life of high-quality flexible tiles is from 20 to 30 years, which is comparable to middle-class metal tiles.
Secrets of saving on flexible tiles
Buy material in the off-season (autumn-winter), when prices from dealers are lower. Savings are also achieved by choosing tiles with a one-sided topping (if only one slope is visible) or simple cutting forms, which are produced faster and are cheaper.
However, the absence of the need for a complex rafter system (due to the lightness of the material) and high maintainability (replacing one shingle takes minutes) compensate for these costs. This is a choice for those who value silence in the house and the absence of rain noise.
Comparative analysis and final recommendations
To summarize the review of budget roofing materials, we can say that there is no universal answer to the question “what is best to cover,” since each case is individual and depends on many factors. If the priority is the minimum price and speed of installation for a temporary structure, then roofing felt or simple slate will be out of competition. For permanent residence and long-term prospects, it is worth taking a closer look at metal tiles or high-quality corrugated sheets.
When choosing, it is necessary to take into account not only the cost of the material “on the shelf”, but also logistics, the cost of additional elements (ridges, valleys, cornices), which can amount to up to 30% of the estimate. A cheap roof can become expensive to maintain if you skimp on waterproofing or ventilation gaps, so an integrated approach to design is required. Always check quality certificates and material compliance with GOST or TU.
☑️ Checklist before purchasing a roof
Do not forget that even the cheapest material, installed with all the technology and love, will last longer than premium material installed with violations. Study the manufacturers' instructions, watch video tutorials, or hire trusted professionals who specialize in the selected type of coating. Your roof is the main protector of your home from the elements, and its reliability directly affects the comfort and safety of your property.
Key takeaway: The cheapest roof is not the one that costs the least to purchase, but the one that requires minimal investment in repairs and maintenance over 10-15 years of operation.
What is the cheapest material for a garage roof?
For a garage roof, the most budget-friendly option is traditionally considered to be roofing material laid in 2-3 layers of bitumen mastic, or the use of simple flat slate. Also, an economical solution would be corrugated sheeting with a minimum sheet thickness, if the design allows for a slope for water drainage.
How long does a cheap roof really last?
The service life of budget materials varies: roofing felt lasts 5-10 years, euro slate (ondulin) - 10-15 years, regular slate - 20-30 years, and economy class metal tiles, with proper care, can last up to 30-40 years.
Is it possible to put a new roof on an old one?
Yes, some materials, such as soft tiles, euro slate and flexible tiles, can be laid over the old covering without dismantling it, if the base (lathing and rafters) is in good condition and can withstand the additional load.
What is cheaper: metal tiles or corrugated sheets?
As a rule, corrugated sheeting is cheaper than metal tiles per square meter, since its production technology is simpler and the metal consumption for profiling is less. However, the difference in price may be offset by the cost of additional elements and the complexity of installation.
Do you need a vapor barrier for a cheap roof?
Yes, vapor barrier is necessary for any type of roof in a heated house, regardless of the cost of the material. It protects the insulation from getting wet by vapors from inside the room, preserving its thermal insulation properties and preventing rotting of wooden structures.
