Cost by roof scope

Roof pricing moves on area, pitch, how many layers come off and what the deck looks like underneath. Every row is priced against the Reading median.

ScopeWhat it includesTypical installed cost
Overlay on a simple ranch roofSingle layer, 4:12 pitch, no tear-off$9,200$12,100
Standard tear-off and replaceOne layer removed, architectural shingle, walkable pitch$12,600$17,000
Two-layer tear-offExtra removal and disposal, same footprint$14,800$20,000
Steep or cut-up roof8:12+ pitch, multiple valleys, dormers, staging$18,500$25,200
Replacement with deck repairPartial resheathing found after tear-off$17,000$23,700
  • Tear-off and disposal is priced per layer — quotes that omit a second layer are the most common source of change orders.
  • Decking is unknown until the old roof is off. Reputable quotes state a per-sheet resheathing price up front.
  • Pitch above 7:12 requires fall protection and slows the crew, which shows up as labor, not material.

Basis: Each scope is priced as a multiple of the modeled Reading median for flat roof replacement, so the scenarios, the size table and the calculator always agree. · Hometriva methodology
