Two neighbors get roof quotes; one pays thousands more. Why? Roof pricing isn't mysterious once you know the five factors that drive it.
The five factors
Size — measured in squares (100 sq ft), the base of every inspection. Pitch — steeper roofs need more safety equipment, more labor, and more material. Material — three-tab, architectural, Class 4, or metal can double or triple the number. Complexity — valleys, dormers, chimneys, and skylights all add flashing labor. Decking condition — hidden rot discovered at tear-off is the most common change order.
Comparing quotes fairly
Make sure every bid covers the same scope: tear-off, decking repair rate, underlayment type, ventilation, and both warranties. The cheapest number usually leaves one of those out. Our inspections itemize everything — free, and no surprises at the final invoice.
Frequently Asked Questions
What determines the cost of a new roof?
Size, pitch, material, and complexity are the biggest factors, followed by decking condition, access, and permits. Material choice alone can double or triple the total.
Why do roofing quotes vary so much?
Usually because they don't include the same work. One may cover full tear-off, decking replacement, new flashing, and ventilation while another omits them. Compare scopes line by line, not just totals.
