What homeowners should know first
Roof replacement cost is driven by size, slope, tear-off complexity, material choice, flashing details, ventilation needs and whether damaged decking or accessories must also be replaced.
Homeowner roofing guide
Replacement cost depends on roof size, complexity, material and condition.
A roof replacement is not priced by square footage alone. The design of the home, the material chosen and the existing roof condition all shape the total scope.

Quick answer

Homeowner checklist
Valleys, dormers, steep sections, low-slope transitions and multiple penetrations all add detail and labor to a replacement project.
Asphalt shingles, metal systems and upgraded accessories can change the budget, as can underlayment, ridge ventilation and flashing packages.
Once the old roof is removed, deteriorated decking or other hidden issues may need correction before the new system is installed.
