Build a reviewed flat roofing takeoff from the drawings, price it with your own cost and sell rates, and carry the same quantities into a clear customer quote.
What the estimate needs to carry
A finished price depends on more than one quantity. Keep the counts, measurements, schedules, notes, and scope gaps visible while the estimate comes together.
Low-slope drainage calculations
Membrane seam lengths and overlaps
Parapet wall and edge flashing
Insulation attachment patterns
How it works
Move one reviewed scope from the drawing into your pricing and on to a quote your customer can accept.
Start with plan-linked AI suggestions for the counts and measurements in scope.
Accept, dismiss, and correct the work against the source sheets.
Calibrate measured sheets and complete the scope with manual takeoff tools.
Collect every page, add your pricing, and prepare an editable customer quote.
What you leave with
Review plan-linked suggestions for Roofing Membrane, Insulation, and Cover Board against the source sheets before accepting or dismissing them.
Use calibrated manual counts, lines, polylines, areas, and rectangles to correct plan geometry; separately verify trade inputs such as square feet, linear feet (seams), and perimeter length.
Roll reviewed flat roofing quantities up by label across loaded pages and disclose incomplete page collection before export.
Export every takeoff row with its source and review state to CSV, or create editable quote lines from accepted AI and manual work. Material conversion, waste, labor, and pricing remain estimator-owned.
Scope behind the price
Use these categories to complete the scope behind the customer-facing total. Confirm plan notes, specifications, alternates, assemblies, waste, and local requirements before turning reviewed quantities into materials or pricing.
