What Moves a Roof Replacement Budget
01
Decking condition
Soft or damaged sheathing discovered during tear-off adds repair and replacement work beyond the original scope.
02
Local permit codes
Permit fees and required inspections differ by municipality, and your ZIP code helps reflect those local requirements.
03
Underlayment and ventilation
Weather underlayment, drip edge, and ventilation components affect both material and labor totals.
04
Disposal and access
Removal volume, dumpster placement, and steep or difficult access can change the cost of the project.
