Roofing Cost Formula

Roofing Cost = (Roof Size × Material Cost per sq ft) + (Labor Rate × Hours)
Example:
If your roof is 2,000 sq ft, materials cost $4 per sq ft, and labor is $50 per hour for 40 hours, the calculation is:\n(2,000 × $4) + (50 × 40) = $8,000 + $2,000 = $10,000 total cost.

Knowing how to calculate your roofing cost is as simple as using this formula. Your output shows how much you’re actually spending after accounting for materials and labor.
