Clay tiles are indeed heavier than asphalt shingles, making them the correct response to the question. Clay tiles are dense, often weighing between 5 to 10 pounds per square foot, depending on their size and thickness. This significant weight provides durability, making clay tiles resistant to harsh weather conditions and long-lasting compared to many other roofing materials.

In contrast, asphalt shingles are much lighter, generally weighing between 2 to 4 pounds per square foot. This lighter weight facilitates easier installation and handling, often making asphalt shingles a popular choice for various roofing projects.

Understanding the differences in weight between these materials helps in planning the structural requirements of a roof, as heavier materials like clay may necessitate additional support or a more robust framing system to safely carry the load. This is a crucial consideration when selecting roofing materials, especially in regions prone to heavy snowfall or severe weather conditions.
