Roof Rat Social Structure and Group Size Roof rats (Rattus rattus) are highly social animals that often live in groups known as colonies. A typical roof rat colony consists of 3 to 15 rats, though this number can vary depending on environmental conditions and resource availability.. What Are Roof Rats And Why Group Size Matters Roof rats (Rattus Rattus) are agile, arboreal rodents commonly found in attics, trees, and upper building levels. Understanding how many roof rats live together matters because group size affects damage potential, disease transmission risk, and control complexity. Larger groups mean more rapid property damage and faster spread of contaminants.
