How To Estimate The Average Cost Of A Slate Roof
To estimate the average cost of a slate roof, first determine the total size of your roof in squares. One roofing square equals 100 square feet of roof surface. Multiply the number of squares by the average cost per square for your chosen slate roofing system.
Roof complexity, ventilation upgrades, underlayment requirements, tear-off requirements, and structural reinforcement can increase total installation costs.
