Try a sample roof price range

Teaching example: 2,000 square feet at an assumed $7 per square foot gives $14,000 before a chosen 15% range either side. Enter your own area and fully scoped selling rate. This doesn't measure a roof or issue a customer quote.

Base = roof area x your rate. Low = base x0.85; high = base x1.15. Stories and material label the scope to review; they don't silently change your rate. The 15% band is chosen for this example and isn't an accuracy rating. No address, contact collection, storage or transmission.
