Understanding Clay Tile Roof Characteristics
Clay tile roofs have unique properties that affect solar installation. Traditional clay tiles are fragile and can crack under pressure. They require special handling during solar panel mounting. Clay tiles also have irregular surfaces that need careful leveling for proper solar array alignment. The weight distribution of clay tiles differs from asphalt shingles, requiring structural analysis before adding solar panels. Proper installation preserves the roof warranty and maintains weather protection.
Clay Tile Composition and Durability
Clay tiles are made from natural clay fired at high temperatures. This process creates a durable but brittle material. High-quality clay tiles can last over 100 years with proper maintenance. However, they can crack if stepped on incorrectly or if mounting hardware is improperly installed. The curved or interlocking design of clay tiles presents challenges for standard solar mounting systems. Specialized flashing and mounting solutions are required to prevent water intrusion.
