Slate roofing contractors by city

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.

Cost. Slate or stone: about $10 to $30 a square foot installed, with materials and labor. This is a national range from HomeGuide, November 2025. Work out the cost for your roof size.

What to ask

• 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?
