Furthermore, clay tiles, with their traditional and heritage-rich appearance, add warmth and appeal to a variety of architectural styles.

The abundance of clay in Arizona has spurred widespread use of clay tiles for roofing, owing to their aesthetic appeal and durability in withstanding harsh weather conditions.

Wood Shingles and Thatched Roofs

Wood shingles and thatched roofs also had their moments in the history of Arizona roofing. In the early days, cedar and redwood were frequently used for wood shingles. These shingles, often steamed and bent to resemble thatched roofs, were laid in evenly spaced overlapping horizontal rows, offering:

  • flexibility in various weather conditions

  • durability

  • resistance to insects and wind

  • natural appeal and insulation properties.

However, thatched roofs had a limited impact on Arizona’s early architecture. Nonetheless, some homes constructed between 1927-1930 showcased jerkinhead roofs that replicated thatch in the Spanish Colonial and Mission styles.

Modern Roofing Materials and Techniques

Today’s roofing techniques and materials have significantly evolved, shifting from basic structures to sophisticated systems, offering both durability and aesthetic appeal. Tin roofs, for instance, gained popularity in the United States from 1860 to 1920, with the first tin roof in the Arizona territory being installed on a retail store.

Contemporary roofing incorporates a variety of materials including:

  • Shingles

  • Clay tiles

  • Wood shake shingles

  • Asphalt shingles

  • Metal roofing

These materials, particularly metal roofs, are resistant to melting or warping under the intense Arizona sun and exhibit resilience against wind, sand, and storms. Architectural styles such as Ranch, Pueblo Revival, Contemporary/Midcentury Modern, and Spanish Mission have also influenced modern roofing materials and techniques.

The Influence of Spanish Architecture on Arizona Roofing

Spanish architecture has left an indelible imprint on Arizona’s roofing styles. Structures such as the Mission San Xavier del Bac and the ruin of Mission San José de Tumacácori, dating back to the late 1600s and early 1700s, respectively, showcase this influence. Red clay roof tiles have become characteristic of Spanish Colonial and Spanish Mission homes in the region, reflecting the enduring influence of Spanish architecture on Arizona’s roofing styles.

Spanish roof tiles are particularly resilient to the climate of Arizona due to their composition of durable clay, which enables them to withstand the intense heat and wind. In addition, they offer advantageous features such as fire resistance and long-lasting performance.

Spanish Roof Tiles and Their Adaptation
