Roof and exterior takeoff from aerial imagery. No ladder, no second trip.

Estimating

• A Measurement Nobody Can Export Gets Retyped

  Every hand-retyped quantity is a chance to transpose a digit into the one document everybody later compares against. Export format is an accuracy feature.

• Squares, Waste, and the Number That Goes on the Order

  Surface area is not an order quantity. Waste is driven by roof complexity rather than size, and treating it as a flat percentage is how crews run short.

• What a Measurement Needs To Survive a Claim

  An adjuster is not disputing your arithmetic. They are asking what the number was derived from, when, and whether it can be checked independently.

Measurement

• Footprint Is Not Area, and the Difference Is the Slope Factor

  Surface area is footprint times a factor that depends only on pitch. The arithmetic is one square root, and getting it wrong costs a whole order.

• The Capture Date Decides Whether the Measurement Is Real

  Aerial imagery is a series of snapshots, not a live view. Which snapshot a measurement came from is often the only thing that matters about it.

• What an Aerial Measurement Cannot See

  Remote takeoff is accurate about the things it can observe. Knowing which parts of a roof it cannot observe is what makes the number safe to quote from.
