When it comes to choosing a roofing material, the debate often centers around whether traditional clay tiles or roof shingles are the better option. However, one available option in our market is concrete roof tiles. Naturally, the question arises – is clay or concrete tile the superior choice? Concrete tile prices are more accessible and are often considered its sole advantage. But is it really so?
Production and Appearance:
- Made from a mixture of sand, cement, and water
- Various color options available, including a faithful imitation of traditional clay tile’s red hue
Concrete tiles are manufactured from a blend of sand, cement, and water. After pouring into molds, coatings are applied to the surface to provide color and protect it from weathering. Thanks to this process, concrete tiles have an advantage over clay tiles in terms of color variety, including a faithful reproduction of the classic red color of traditional clay tiles.
Durability and Maintenance:
- Typically offer a 25-year warranty, with an average lifespan twice as long
- Greater moisture absorption compared to clay tiles, potentially leading to mold and mildew issues
However, concrete tiles have a drawback compared to clay. While clay tiles acquire their natural reddish hue through the firing process, which remains unchanged over the years, concrete tiles may fade after prolonged exposure to rain and sunlight.

One of the disadvantages of concrete tiles is their higher moisture absorption. Clay tiles have a water absorption rate of only six percent, whereas concrete tiles have a rate of up to thirteen percent. Although this doesn’t mean concrete tiles leak or fail to perform their function, it can result in the tiles absorbing enough water during prolonged rainfall to become heavier. Consequently, the roof structure must be slightly stronger.
Moisture absorption can also be a disadvantage of concrete tiles compared to clay, as accumulated moisture can lead to more frequent occurrences of mold and mildew. This not only alters the color of the roof but can also accelerate its deterioration. However, this isn’t an insurmountable problem, as mold can be removed, but it does require slightly more frequent maintenance than clay tiles.
Temperature Resistance and Conclusion:
- Better withstand low temperatures compared to clay tiles
- Both options suitable for various climates, with clay better for warmer regions and concrete for colder ones
One advantage of concrete tiles, beside price, is their better resistance to low temperatures. When exposed to extremely low temperatures followed by thawing, clay tiles may crack, whereas concrete tiles handle low temperatures better. Hence, clay tiles might be a better choice for warmer regions, while concrete is preferable for colder climates. In terms of our climate, both types are equally suitable.
The conclusion is self-evident – if the standard red color suits you and a slightly higher price isn’t an obstacle, clay tiles are undoubtedly the better option. On the other hand, if you desire a roof in a different color and appreciate the cost savings, concrete tiles are the right choice.
Although clay tiles are more durable, opting for quality concrete tiles is still a wise decision. Most manufacturers offer a 25-year warranty on concrete tiles, with an average lifespan double that.
