How Clay Roofing Tiles Are Produced

Modern clay tiles are still made using techniques similar to those used centuries ago. Natural clay is extracted, shaped into tiles, and then fired in kilns at high temperatures—usually above 1,000°F. The exact shade and texture of each tile are influenced by the mineral content of the clay and the conditions during firing.

Some manufacturers add glazes or use special firing techniques to produce a wider range of finishes, but even unglazed tiles develop unique patinas over time, contributing to their lasting appeal.

Clay Tile Roofing Styles

Several tile styles are used in clay roofing, each offering different aesthetic and functional qualities:

• Spanish Tiles (S-Tiles): A classic curved design that creates a rippled pattern on the roof. Common in Spanish Colonial architecture.

• Mission Tiles: Consist of two separate pieces—a concave pan and a convex cover. Often seen on historic buildings in the Southwest.

• French Tiles: A flat, interlocking tile with raised edges that help direct water flow. Provides a refined, symmetrical look.

• Flat Tiles: Rectangular and interlocking, these tiles offer a clean, modern appearance and can mimic wood or slate.

• Roman Tiles: Similar to Spanish styles but with a more subdued curve, suitable for contemporary or traditional homes.

Color Options and Surface Finishes

Clay roofing tiles are available in a wide palette of colors, most of which come directly from the natural mineral content of the clay. Popular colors include:

• Traditional terracotta

• Deep reds and browns

• Earthy yellows and oranges

• Custom shades and glazed finishes

Some tiles fade slightly over time, while others maintain their original color for decades, depending on their finish and exposure.

Is Clay Tile Right for My Home?

Clay tile is a long-lasting, visually striking option, but it’s not ideal for every home. Consider the following before choosing clay tile for your roof in Raleigh:

Roof Slope

Clay tiles work best on moderate to steep slopes (minimum 4:12). They aren’t suitable for flat or low-slope roofs without major adjustments.

Home Style

This roofing style pairs beautifully with Mediterranean, Spanish Colonial, Tuscan, and Southwestern architecture, especially when using traditional barrel tiles. For modern or industrial-style homes, flat clay tiles offer a clean, contemporary look that complements sleek design elements.

Climate Fit

Clay tile performs exceptionally well in hot, humid climates due to its natural resistance to heat and moisture. However, in regions subject to freeze-thaw cycles, it is crucial to use high-quality, frost-resistant clay tiles to prevent cracking and long-term damage. In storm-prone areas, proper installation with secure anchoring is essential to ensure durability and safety. While clay requires minimal upkeep, occasional cleaning may be necessary in shaded or damp areas where moss or debris can accumulate.

Weight Considerations

Clay tiles are a durable and long-lasting roofing option, but they are also significantly heavy—often weighing over 850 pounds per roofing square (100 square feet). Because of this, it’s essential that the underlying roof structure is engineered to support the added load. In some cases, structural reinforcement may be necessary, especially when replacing a lighter roofing material with clay tile.

HOA or Historic Districts

In Raleigh, certain neighborhoods—particularly those governed by Homeowners Associations (HOAs) or located within historic districts—may have specific regulations regarding roofing materials, colors, and styles. Before beginning any roofing project, especially with distinctive materials like clay tile or slate, it’s important to consult local guidelines to ensure full compliance with community or preservation standards.
