Barrel tile roofs (also called “mission tiles” or “Spanish tiles”) are roofs composed of semi-cylinder shaped tiles laid in interlocking concave and convex columns. This type of roof is commonly seen on Spanish-style homes that are popular in Texas. Not only are barrel tiles beautiful, they’re also very durable and practical. These strong tiles can be made from either plastic, concrete, clay, or metal. Although they are widely used throughout the state of Texas and provide excellent protection from extreme weather, barrel tiles can give uninvited rodents and wildlife an easy entrance into your home. Slipping underneath roof tiles is a common way for animals to make their way into your attic or garage in search of shelter. To put this into perspective, rats and bats can squeeze their bodies through holes the size of a quarter, so even the smallest gap between tiles can make your house vulnerable to pests.
