Field And Specialty Tile
The tiles that cover the majority of the flat surface of the roof are called field tile. Some roof shapes, particularly conical towers or turrets, require tiles of graduated sizes, and some shapes or patterns of field tile also require specially shaped finish tiles to complete the roof covering package. Other uniquely-shaped tiles were made to fit odd-shaped spaces and places including dormers and valleys, roof hips, rakes, ridges and corners. There are also finish tiles that fulfill certain needs, such as eave closures or clay plugs called birdstops. These are intended to keep out snow and rain, and birds from nesting in the voids under the bottom row of curved tiles. Different patterns and designs can also be created by combining, or mixing and matching flat tiles with dimensional tiles.
How Tiles Are Attached Return To Top
The method used to attach clay roofing tiles varies according to the shape, size and style of the particular tile. For the most part, traditional and modern methods of installing clay roofing tiles are very similar, except that modern practice always includes the use of wood sheathing and roofing felt. But most of the earliest clay roofing tiles were laid without benefit of wood sheathing and hung directly on roofing laths and battens that were nailed to the roof rafters this practice continued up into the mid-19th century in some regions. While this method of attachment allowed for plenty of ventilation, and made it easy to find leaks and make repairs, it also meant that the overall water-tightness of the roof depended entirely on the tiles themselves.

Gradually, the practice evolved of nailing roofing tiles directly onto continuous wood sheathing, or hanging them from nibs on horizontal lath that was attached to roof rafters or sheathing. Some kinds of tile, especially the later Mission or Barrel tiles were laid over vertical strips or battens nailed to the sheathing, or the tiles were fastened to wood purlins with copper wire.

Clay Barrel Tile Roofing
Traditional clay barrel tiles are semi-cylindrical. Mission-style barrel tiles are laid in an interlocking pattern, with flat or concave tiles forming a base and rounded convex tiles placed on top to create a rippled or ridged surface. The mission-style tiles get their name from the Spanish Missions, which used these curved tiles as a more waterproof replacement for earlier roofing materials.
An older variation of the barrel roof style is the imbrex and tegula tiles used in ancient Greek and Roman architecture. This style of barrel tile featured a wide, flat or slightly curved under piece called the “tegula” and a more narrow, semi-cylindrical piece called the “imbrex,” which would cover the upturned edges of the tegula. With their roots in ancient history, barrel clay tile roofs can be found throughout the Mediterranean today.
Spanish S-shaped barrel tiles date back hundreds of years Spain and were first introduced to American architecture in Florida. They are easier for roofers to lay than other types of barrel tiles since they come in a single shape.

Roof tiles are primarily made to keep water out of a home. However, they differ from traditional asphalt shingle roofs in both their material composition as well as their looks. As far back as the 1600s, slate tile roofs were being used, and clay roofs can be traced back as far as 10,000 BC! Slate and clay were popular because they were locally available materials but as we moved into the 19th century, concrete and metal tiles started to appear on a regular basis.

As the name suggests, interlocking roof tiles interlock at their sides, making them waterproof. They are an alternative to double lapping, which requires more tiles to cover the same roofing area.
Moreover, interlocking tiles are larger. Therefore, fewer of them are needed to cover the entire roof. Another advantage of this type of tile is a quick and straightforward installation process. That means they are more cost-effective to install than plain tiles.

Everything You Need To Know About Ceramic Roofs
Ceramic tile shingles offer a touch of elegance and style to any roof. They are perfectly suited for homeowners who desire a distinctive exterior design with a resilient nature. Made for durability and outstanding performance, ceramic roof tiles have proven strong against water, wind, and extreme heat so you can rest easy knowing that your dream home is built to last.
Sometimes, ceramic tiles may be synonymous with clay tiles. This is because ceramic tile shingles originate as clay tiles milled clay is mixed with additives such as water and sand and then shaped into custom molds of various shapes and sizes. Once removed from the molds, the shingles are carefully dried and later fired in a high-temperature kiln to ensure durability and fire resistance. This creates the well-known terracotta clay tile of natural earthy-brown and red hues.
Unglazed terracotta clay tiles offer distinctive natural tones but remain very porous and are susceptible to mold or water stains over time. This is why natural clay tiles must be either treated with a sealant or glazed for protection from the elements. Glazing is a process that involves the bonding of a glass-like surface finish to the clay tile through a second kiln-firing process. Dyes may be blended with the glaze before the second firing, resulting in a waterproof and stainproof ceramic tile in the color of your choice.

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.
They are energy efficient holding heat in themselves rather than transferring it to the attic below. Due to the shapes they are manufactured into, they allow good airflow which helps keep heat from building up on the roof, allowing it to dissipate into the atmosphere.
Historical Background Return To Top
The origin of clay roofing tile can be traced independently to two different parts of the world: China, during the Neolithic Age, beginning around 10,000 B.C. and the Middle East, a short time later. From these regions, the use of clay tile spread throughout Asia and Europe. Not only the ancient Egyptians and Babylonians, but also the Greeks and Romans roofed their buildings with clay tiles, and adaptations of their practice continue in Europe to the present. European settlers brought this roofing tradition to America where it was established in many places by the 17th century.

Archeologists have recovered specimens of clay roofing tiles from the 1585 settlement of Roanoke Island in North Carolina. Clay tile was also used in the early English settlements in Jamestown, Virginia, and nearby St. Marys in Maryland. Clay roofing tiles were also used in the Spanish settlement of St. Augustine in Florida, and by both the French and Spanish in New Orleans.

What Are The Primary Differences Between Concrete And Clay Tiles
1. Water Absorption
Concrete roofing tiles have a water absorption of about 13%, while clay roofing tiles have a water absorption of about 6%. Consequently, this higher rate of water absorption leads to the development of mildew and stains on concrete tiles.
Absorbed water also increases the already heavy weight of a concrete tile and puts increases pressure on the roof structure. These issues are very minimal in clay tiles due to their low water absorption rate.
Concrete tiles can weigh almost 40% more than clay tiles. Concrete tiles can weigh anywhere from 820 to 1.100 pounds per square , depending on the style, while most clay roofing tiles weigh only 600 650 pounds per square. As a result, it is more difficult for the roof structure to adequately support the heavier weight of concrete tiles vs. clay tiles.
In some cases, concrete tiles are not recommended for use on buildings, unless the roof framing is reinforced to support the added weight.
Propensity to crack and shatter
In colder climates, clay tiles have a tendency to crack or shatter due to freezing and thawing cycles. As a result, clay tiles are mostly found in warmer climates.
Conversely, concrete tiles are not as susceptible to damage due to freezing temperatures, and therefore can be used in almost any climate.
4. Color Longevity and Appearance
Due to its porous nature, concrete tiles are also more prone to stains than clay tiles.
Terracotta Roof: Pros And Cons
Terracotta roof tile has amazing benefits that will work well for many homeowners. However, there are drawbacks that make it a less than ideal choice for some situations.
- Durability If a clay tile roof is installed well, it can last over 100 years. These tiles are resistant to rot, fire, and wind. In addition, they are durable to some objects that fall from the sky like hail.
- Style The look of terracotta roof tile is unlike any other. They elevate the look of historic and contemporary buildings and give homes a rustic charm that is hard to match with other roofing tiles.
- Eco-friendliness Manufacturers can make terracotta roofing tiles from locally sourced raw materials. In addition, clay roof tiles have thermal energy properties that allow them to reduce the heat loss and absorption. Also, they create a good heat transfer barrier that keeps your home warm in the winter and cool in the summer.

The Terracotta Roof: A Brief History
Terracotta, which means baked-earth, comes from a coarse and porous clay from the earth. Ancient artisans used it to construct vessels like pots and sculptures because it was an inexpensive and moldable material. It has been used to create roofing tiles as long ago in coastal areas in Europe in ancient Greece and in Asia in ancient China.
The use of terracotta clay roof tiles throughout Europe and Asia continued into the Renaissance when explorers carried these tiles into the New World. Architects have found evidence of clay tiles in old English settlements like Jamestown and Roanoke. Spanish settlements in Florida also used clay roof tiles.
In the current era, many people use terracotta roofing tiles across Europe and all around the world. In the United States, architects have used clay tiles in Mission-style architecture as well as some Craftsman-style homes. You can see these roofs throughout California and the midwest.
