Your unlimited resource for slate and tile Identification and Matching Service There are many types of slate and tile on the roofs of North America.  In most cases, we can immediately identify where the slate was quarried or can tell you which tile plant manufactured the material you need. However, if additional resources are needed to find the origin of a particular product, we have them at our direct disposal.  Once the step of identification is taken care of, we can provide the slate or tile needed for your project.
