Tile Roof Pros And Cons
Tiles come with many advantages and have their disadvantages that turn some homeowners away from installing one. The biggest pro of tile roofs and why they are so popular is their durability and resilience. Thus, they are ideal for places with exposure to salt air or areas with frequent, heavy rainfall or snowfall. Once the tiles are installed, manufacturers offer a 50-year warranty to back up their quality.
Aside from this, tile roofs are also impervious to insect damage and rot and are very easy to maintain as leaks are rare. Because they are thick, they prevent water, cold air, or hot air from penetrating the interior, making them one of the most energy efficient and environmentally friendly roofing materials available on the market. Homeowners can choose from various colors, styles, patterns, and textures when they install tiles, giving them the freedom to choose the look of the exterior of their home.
Because of their many advantages and longevity, tiles are one of the most expensive roofing types that can cost double or triple more than concrete or metal structures. The high cost is also attributed to the complex installation that requires professional contractors with extensive roofing experience. Another one of the major downsides of tile structure is that they are heavy. Not all home structures can support them, which would require an additional support structure.
Why Are Greek Roofs Flat
Eventually, they discovered that the flat tiles were more effective when curved upwards slightly on the edges beneath the tegula or curved tile. These raised ends prevented water from seeping beneath the tegula tiles. The Greeks also added ridges on the back of the flat tiles to make them easier to hang on the roof.
Asphalt Shingles Vs Concrete Tiles
Asphalt shingles remain far more common than concrete tiles around the world. Also, asphalt shingles are an affordable option with an average cost of $6,750 for a 1,500 sq. ft. roof versus the average cost of $30,000 for a concrete tile roof. However, asphalt roofs rarely last longer than 20 years compared to a concrete roof that can last 100 years or more when properly installed and maintained.

Concrete Roof Tiles Prices
Although concrete roof tile prices are high at $400 to $2,000 per square, they are more difficult to install than asphalt shingles and take the roofer twice the time. The durability of the concrete tile offsets the cost. When properly installed, the tiles can last 100 years or more, but asphalt tiles rarely last longer than 20 years. Even though the initial cost of the concrete roof tiles is higher, the extended lifespan makes it a worthwhile investment.
Styles And Wide Variety Of Tile Profiles
In North America, tile roofing is often associated with the southwestern US feeling. Deep red or Terracotta, Spanish-style clay tiles on a home with stucco siding is what normally comes to mind when we picture tile roofs. Yet, thats just one possibility.
Historically, Dutch, and European immigrants have been in the business of importing clay tiles into the New World since about 1650.
All the way through the end of the 1700s, tiles were a very popular roofing material that was viewed as superior to wood, because it was fireproof, moss-and-algae-proof, far longer-lasting, etc.
As the industrial age chugged along, corrugated metal roofing started to grow in popularity, which lead to the decline in the dominance of the clay tile market.
Metal is as durable and, in many cases, less expensive than tiles. Yet, there have been at least two clay tile revival periods in the last 200 years, which is why tile roofing has never lost its stature and appeal in the overall premium sloped roofing category.

What Makes Clay Roof Tiles So Appealing
Durable and Beautiful
Clay roof tiles have been known to last over 100 years. They resist high winds, hail, and usually carry a Class A fire rating which is the best rating available. They also keep their good looks for many years adding to your homes curb appeal and resale value.
Clay roof tiles are primarily composed of natural clay and water making them easy to recycle.

Tile Roof Repair Cost
If you need to repair your roof, expect to pay an average cost of $900 and $2,300. The exact cost depends mostly on the problem youre having.

Cement Or Concrete Vs Clay Roof Tiles: Impact On Colors
While clay is the historic and predominant material, concrete is the other primary material option. Clay tiles normally come in two types: glazed or unglazed.
Clay tiles tend to hold color much better than cement tiles, especially in the case of Terracotta clay.
Regardless of the material, color is mixed in with the material during the production. With cement, color will fade somewhere between 30 and 50 years. With clay, the color will hold steady for 50 to 70 years. And with Terracotta, it is indefinite, or for sure, 100+ years.
Adding in tile shape and texture, provides a rather limitless variety of options. But generally, architects go for more popular and established styles like Terra-cotta barrel vault tiles, although flat tiles are also common, especially in more wind-prone areas where their low-profile can be beneficial.
Multi-colored tiles on a roof are an option that goes somewhat against the historic norms. Accessories are part of the installation, such that tiles shaped and formed for ridges, hips and gable ends add even more opportunity for greater variety.
What Are The Advantages Of A Concrete Roof

Weight Is A Serious Concern
For homes where weight is a concern, many concrete tile manufacturers offer lightweight options, however those options still weigh 5.5 – 7.5 pounds per square. Standard-weight concrete roof tiles generally weigh between 9.5 to 12 pounds per square foot .. Even concrete roofing products that are labeled as lightweight concrete tiles by the manufacturers are made with a lightweight aggregate, like expanded shale, instead of sand, and they are also heavy because concrete by design is an extremely dense material. By comparison, CeDUR Roofing Shakes are just an astonishing 1.7 pounds per square.
Weight Loading On A Roof
Weight loading on a roof
It isnt uncommon to be handed a specification where a new material is being specified to replace the original.
In most cases necessary investigation has been undertaken, and it has been concluded the roof is able to support the additional load. However there are instances we have seen, where this has been overlooked.
Weight loading on a roof structure is obviously very important and when roof coverings are being replaced it is essential that we make sure that, if we are specifying a change of material which will increase the load on the roof, we check that the existing structure can accommodate the increase in load.
This will usually involve employing a structural engineer. If necessary the structure may have to be strengthened, but if this is not possible, then we will have to consider another roof covering.
There are some misconceptions about the weights and loads of some roofing materials so be careful. The most common is the belief that the heaviest roof tiles are concrete interlocking tiles. Heavy as they are, this is wrong.
Here are some examples which demonstrates this,
- A Marley EterniteDouble Roman concrete interlocking tile weighs 47Kg/m².
- The same manufactures concrete plain tile weighs 73.8Kg/m².
- And their Acme plain clay tile weighs 64Kg/m².
As you can see a plain tile is around 50% heavier.

Minimum Pitch For A Tiled Roof
Tiles can only be installed on roofs with a pitch between 2/12 and 12/12, with the first number referring to the vertical rise of the structure in inches while the second one refers to the horizontal length of the structure. If the structure is any lower than 2 inches, it may not drain sufficiently, and any higher than 12 inches and the structure will be too steep to accommodate the heavier tile. The most common roof pitch in residential homes is between 4/12 and 9/12.
What Is The Minimum Roof Pitch For Tiles
In most instances, 35° will be the minimum pitch for plain concrete tiles, which is another reason why the material is the preferred choice for those who use them regularly. Clay single camber plain tiles can pitch down to 30° manufacturer dependant, although the vast majority available have a limit of 35°.

Slate Roof Tiles Cost
The cost to install slate roof tiles is between $7 and $30 per sq. ft., depending on the , thickness, and overall quality of the tiles you will use. The big discrepancy in cost is that some slate types, such as synthetic slate tiles, are more affordable than regular slate. Synthetic slate tiles are made of plastic and rubber, so they can be recycled and reused, which is another benefit of this type of roofing. However, synthetic slate tiling is not recommended in areas with a harsher climate as they can curl, crack, and disintegrate because of it.
While the material itself can be quite affordable, the installation is one of the most expensive. Each slate is individually drilled to make a hole in it and nail it to the structure, which is a time-consuming process that adds to the cost of the project. However, once installed, slate is one of the most durable and high-quality materials you can use that can last up to 150 years, more than any other roofing type.
Average Cost Of Different Tile Styles
- Spanish Tile $2.00 to $4.00 per square foot.
- Scandia Tile $2.00 to $4.00 per square foot.
- Double Roman $2.25 to $4.80 per square foot.
- Flat Shake $2.29 to $2.49 per square foot.
- Pantile Average cost: $2.50 per square foot.
- Barrel Tile $3.00 to $6.50 per square foot.
- French Tile $3.20 to $3.90 per square foot.

How Are Lightweight Concrete Tiles Made
What sets lightweight tiles apart from other tiles is the materials used in the concrete mixture. The manufacturing process for lightweight concrete tiles includes a combination of clay, slate, or expanded shale that is fired them in a kiln. Once these products are heated for a long period of time, they dry out and become highly porous. After being in the kiln they are cooled and used to mix in with the concrete.

Concrete Tile Roof Installation
The tile roof installation process of concrete roof tiles is similar to other tile roofing materials. They come in various shapes and sizes, and the installation process depends on the particular tile. Flat tiles interlock in a similar fashion to an S tile. If there is an existing roof, then the old tiles are removed. An underlayment or waterproof membrane is laid. In a hot climate, battens are nailed down to the roof deck, so the tiles are elevated to promote ventilation.
If a penetration in the roof exists, such as those made by chimneys or skylights, the area is flashed to prevent water infiltration. The tile is then installed. The tiles are laid first at the edge of the roof, and then the roofers work backward with each tile course nailed to the battens. The laying process is in an overlap fashion to create a watertight installation. Ridge caps and end pieces are then affixed to the tiles to complete the job.
Concrete tile roofs are difficult to install and take time, especially on a roof with extensive slopes or unusual shapes or patterns. A roof with a high pitch requires additional work, such as sealing the edges. Also, multiple skylights and chimneys increase labor costs. To install, a roofer will charge from $4 to $8 per sq. ft. or $400 to $800 per square, depending on the pitch of the roof. Installation for mid-range cost is from $6,000 to $12,000 for labor in addition to the roofing material cost.
