What Are Concrete Tile Roofs? (2024 Guide)
Concrete tile roofing is durable, long-lasting, and a budget-friendly alternative to traditional tile roofing. It’s also aesthetically pleasing, and can offer a stylish addition to any home. Read our guide below to better understand how concrete tile roofs work, how much they might cost you, and pros and cons of installation.
Understanding Concrete Tile Roofing: Materials and Manufacturing
Concrete tile roofs have evolved significantly since their 19th-century introduction. Today’s manufacturing processes yield high-quality, durable tiles that can withstand various weather conditions and last for decades.
Composition of Concrete Tiles
Concrete roof tiles are made of a composite of sand, cement, water, and iron oxide. These materials collectively create a sturdy, weather-resistant product that can mimic the appearance of other roofing materials. The addition of iron oxide allows manufacturers to produce tiles in various colors so that the tiles can complement various architectural styles.
Modern Production Techniques
The process of manufacturing concrete tiles has become fully automated, and lower production costs have made concrete tiles an affordable option for many homeowners. The automation process creates tiles in various styles and profiles that can suit different design preferences.
Advantages of Choosing Concrete Tile Roofs
Concrete tile roofs offer several benefits that make them an attractive option for homeowners. Read more about their advantages below.
Durability and Longevity
One of the most significant advantages of concrete tile roofs is that they are especially durable. These tiles are highly fire-resistant, and have earned a Class A fire rating. They can also withstand severe weather conditions, such as winds of more than 125 miles per hour and hail. They can last for 100 years or longer.
Concrete roofs are low-maintenance, but we do recommend that homeowners perform an annual roof inspection. You should also check for damage after storms and remove any debris. Consider professional cleanings if you live in a rainy climate to prevent moss or algae growth.
Energy Efficiency Benefits
Concrete tiles can make homes more energy-efficient. Their thermal mass helps to regulate indoor temperatures by reducing heat transfer through the roof. This can help homes stay cooler and summer and warmer in winter, which can lead to lower energy bills.
Aesthetic Versatility
Concrete tiles come in a wide array of styles, colors, and finishes, which makes them suitable for various architectural designs. They’re available as traditional earth tones, vibrant pastels, and multicolor blends. Modern concrete tiles can convincingly mimic the appearance of clay tiles, wood shakes, slate, and stone.
Potential Drawbacks of Concrete Tile Roofing
There are some potential drawbacks to consider before you choose concrete tile. Read more below.
Weight Considerations
Concrete tiles are especially heavy, and can weigh more than 900 pounds per square foot. This is significantly heavier than many other roofing materials. This substantial weight may require additional structural support, especially for older homes.
Installation Complexity
Installing a concrete tile roof requires specialized skills and knowledge. The complexity of the installation process can contribute to higher labor costs and may limit the number of qualified contractors available for the job. Installation requires correct underlayment, flashing, and batten configuration.
Cost Factors
Concrete tiles are usually more affordable than traditional clay or slate tiles, but they are still more expensive than some other roofing options, such as asphalt shingles. The initial cost of a concrete tile roof can be a significant investment for homeowners.
Concrete Tile Roof Installation Process
Read below to learn the ins and outs of concrete tile roof installation.
Preparing the Roof Structure
You must assess your roof structure to determine whether it can support the weight of concrete tiles before you dive into the installation process. Additional reinforcement may be necessary in some cases. Once your roof is ready, you can remove the old material and make any necessary repairs to the roof deck.
Underlayment and Flashing
A high-quality underlayment provides your concrete tile an additional layer of protection against water infiltration. You must also make sure you have proper flashing around chimneys, vents, and other roof penetrations to prevent leaks. Install an ice barrier along the eaves and in other vulnerable areas if you live in an area that’s prone to ice damming.
Tile Laying Techniques
You must install concrete tiles from the bottom of the roof upward. The laying of concrete tiles requires precision and expertise. Use battens to provide a secure attachment point for the tiles and to make sure they’re properly aligned.
What Is the Cost of Concrete Roof Tiles?
Concrete tile installation costs vary depending on your roof’s size, the project’s complexity, roof pitch, location, and whether your roof requires additional reinforcement. The concrete tiles’ look and quality also determine cost. A concrete tile roof costs $2–$4 per square foot for materials and $9–$18 per foot if you hire a professional to fully install it.

Maintenance and Care for Concrete Tile Roofs
You must properly maintain your roof to maximize its lifespan and keep it performing successfully.
Routine Inspection Guidelines
Perform annual roof inspections to identify and address any potential issues early. Homeowners should look for cracked or broken tiles, signs of water damage, and signs of damage to flashing and sealants. Look out for debris accumulation, too, especially after storms.
Cleaning and Repair Procedures
Algae and moss may grow on concrete tile roofs in areas with high humidity or frequent rainfall. Clean your roof periodically to maintain its appearance and prevent potential damage. Work with experienced professionals to perform repair and avoid causing additional damage to the tile.
Climate Considerations for Concrete Tile Roofs
How successfully concrete tile roofs perform depends on local climate and weather patterns.
Performance in Various Weather Conditions
Concrete tiles can protect your home against sun, rain, and wind, but you must keep in mind the dangers that extreme temperature fluctuations or frequent freeze-thaw cycles pose. If you live in a region that’s prone to heavy snowfall, for example, you must carefully select the roof’s pitch and tile to prevent snow and ice accumulation.
Regional Adaptations and Requirements
The way you must install and maintain your concrete roofs varies depending on your local building codes and climate. You may need additional fastening methods in hurricane-prone areas to keep tiles secure during high winds, for example.

Comparing Concrete Tiles to Alternative Roofing Options
Read below to learn how concrete tiles compare to other popular roofing materials.
Concrete vs. Clay Tiles
Concrete tiles are generally more affordable and easier to install than clay tiles. Clay tiles are longer-lasting and retain their color more successfully, but they’re more expensive and heavier than concrete.
Concrete Tiles vs. Asphalt Shingles
Asphalt shingles are less expensive than other roofing materials, but concrete tiles have longer lifespans, which makes them more cost-effective in the long run.

FAQ About Concrete Tile Roofs
Are concrete tile roofs good?
Yes, concrete tile roofs are durable and energy-efficient. They can withstand winds of more than 125 miles per hour and last for more than 100 years if you properly maintain them. They cost more than many other roofing materials, and may not work on all roofs, though.
Do concrete roofs leak?
Concrete roofs do not usually leak, but may if you improperly install them, or if they incur damage. Regular inspections and maintenance are key to preventing leaks.
Do concrete roofs need to be sealed?
You do not need to seal most concrete roofs because they already come with water-resistant treatment.
Are concrete tiles better than shingles?
Concrete tiles are more durable, energy-efficient, and long-lasting than asphalt shingles.
