Slate roofing basics

Natural slate is a metamorphic rock that splits into thin, durable sheets. On a roof, slates are laid in overlapping courses with a set headlap and fixed with corrosion-resistant nails or hooks. Good slate work also depends on correct flashing in metals such as copper or lead. Because slate roofs often last for generations, repair skills are as important as new installation. Many SRCA members work on historic buildings where matching the original slate and methods is required.
