Assumptions behind this model
- Roof area is estimated from footprint × a pitch/overhang factor (1.08–1.4); actual measured area governs real quotes.
- Installed rates per square (100 sq ft): 3-tab $350–$550; architectural $450–$750; exposed-fastener metal $550–$950; standing seam $1,000–$1,600; concrete tile $900–$1,800 — including tear-off of one layer, underlayment, flashing, and disposal.
- Steep pitch adds 25% labor; second story adds 10%; high-cost metros add 30%, below-average areas subtract 15%.
- A second tear-off layer adds $45–$90 per square. Decking repair is excluded — budget $500–$2,000 contingency on roofs 20+ years old.
- Permit fees vary by jurisdiction ($100–$500 typical) and are treated as included in range midpoints.
