Roof replacement pricing depends on far more than square footage. Roof complexity, tear-off, decking repairs, material, ventilation, flashing, access and disposal can all change the final scope.
The roof area and geometry
Larger roofs require more material and labour, while steep slopes, valleys, dormers, multiple levels and difficult access add time and detailing.
What is underneath the old roof
A quote can assume serviceable decking, but tear-off may reveal damaged wood that needs replacement. The proposal should explain how unforeseen deck work is handled.
Material and system details
Shingle line, metal profile, underlayment, ice and water protection, flashing, ventilation and accessory choices all affect cost.

Online estimates are useful for rough planning, but the roof has to be measured and inspected before a reliable scope can be priced.
