Ceramic tile
|
- Durability of the roof (belongs to high-quality products).
- Noble appearance.
- Safety of all qualities and characteristics for decades.
- Excellent heat and sound insulation.
- Resistance to temperature fluctuations.
- Resistance to aggressive media.
- Ease of use and simplicity of the roof repairs.
- Environmental friendly.
- Fire safety.
|
- Large mass of material that requires a strengthening of the supporting structure of the roof.
- Fragility of the material, it is easily cracked.
- Complexity and high cost of installation, it is difficult to process when sawing.
- Porous surface promotes development of microorganisms.
- Relatively high price (price of quality tiles starts from 15 c.u.)

Polymer-sand roof tile
|
- Durability
- Presentable appearance as that of a natural tile.
- Save all the properties and characteristics for decades (tested in different climatic zones).
- Excellent heat and sound insulation.
- Resistance to temperature fluctuations and impact of micro-organisms (absence of surface porosity).
- Resistance to aggressive media.
- High strength of the material (not beating at random falls during assembly and repair of the roof).
- Easily processed (cut with a hacksaw or "Bulgarian" without the use of special cutting blades).
- It does not require reinforcement of roof structure.
- Ease of use and simplicity of maintenance of the roof.
- Environmental friendly.
- Low price, taking into account preparation of truss construction.
|
- Availability at roofing market of low-quality products from manufacturers who do not respect the production technology and using unstable colorants.
- The products are unknown on the market as a kind of roofing material, low awareness of consumer product properties.

Cement-sand roof tile
|
- Durability (belongs to high-quality products).
- Noble appearance.
- Maintaining of all properties and characteristics for decades.
- Excellent heat and sound insulation.
- Ease of use and simplicity of maintenance of the roof.
- Environmental friendly.
- Fire safety.
- Relatively low cost.
|
- Large mass of the tiles requires a strengthening of the supporting structure of the roof.
- Fragility of the material, it is easily cracked.
- Porous structure affects the frost resistance (temperature changes), favorable for the development of microorganisms.
- High labor intensity and high cost of installation.

Metal shingle
|
- Low weight, does not require reinforcement of truss construction.
- Resistance to temperature fluctuations and "blooms" due to absence of porosity.
- It is easy to be processed.
- Easy and quick installation
- Environmental friendly.
- Fire safety.
|
- Non-durable roof.
- Low heat and sound insulation, which leads to increased demands on thermal insulation and expenses for heat and sound insulation underlying materials.
- Exposure to corrosion, which is especially evident in a humid climate.
- Need for lightning devices.
- High wind resistance and likelihood of resonance oscillations of sheets.
- Observe care when mounting to avoid damage to the protective coating.
- Large quantity of waste, especially for complex geometry of the roof.
- Unhandy in operation.

Bituminous (soft) tile
|
- Low weight, does not require reinforcement of truss construction.
- Excellent heat and sound insulation.
- Ease of handling and installation of the roof material.
- Ability to cover complex shapes of curved roof.
|
- Need to use water-resistant wooden boards, which doubles the cost of coverage.
- Low resistance to temperature extremes and mechanical stresses, leading to cracks and breaks.
- Unhandy in operation (requires accuracy in handling).
- Exposure to aggressive environments and UV rays, the effects of microorganisms.
- Fire hazard.
- Rather high price.

Corrugated sheets (Onduline type)
|
- Low weight, does not require reinforcement of truss construction.
- Ease of handling and installation of the roof material.
- Ease of operation and maintenance.
- Relatively low cost.
|
- Non-durable.
- Exposure to aggressive environments and UV rays, the effects of microorganisms.
- Tendency to fade.
- Large quantity of waste, especially for complex geometry of the roof.
- High windage.
- Fire hazard.
