Slate Patio Cost Per Square Foot
You’ll pay $15 to $40 per square foot for a slate patio. Make sure to use slate paving stones and not slate tile. The thinner tile doesn’t have the strength for use outside, unless it’s put on like a veneer, over the top of an existing pathway, patio or reinforced deck. If you already have a concrete or reinforced patio you’re looking to cover, slate tile installation costs $13 to $35 per square foot.
