About slate roofs

Natural slate is stone split into thin tiles. A good slate roof can last 75 years or more, much longer than the nails and flashing that hold it. So most slate work is repair: new slates where some have cracked or slipped, and new flashing around chimneys and valleys. Slate is heavy and breaks under a careless foot, so the crew needs slate skills, not only shingle skills. Synthetic slate looks like it, weighs less, and is a different product.

What to ask a contractor

  • How many slate roofs has this crew repaired or installed?
  • Can the roof be repaired, or is the whole roof at the end of its life? How can you tell?
  • Where will matching slates come from, and will they match in color and size?
  • Will you use copper or stainless nails and copper flashing?
