How the subtotal is calculated

The example line for old membrane removal is 420 sq. ft. × $6.00 = $2,520.00. This line is one part of the complete 7-item estimate and uses a fictional unit rate.

The document sums the rounded line amounts to $16,940.00 . Tax and markup are not included; a zero tax field in a sample document does not mean a real project is tax-exempt. Confirm the actual treatment for the job you are quoting.

Measurement to verify: Measure net roof area, upstands, penetrations, drainage falls and perimeter edge length. Selection to verify: Identify membrane system, insulation if selected and outlet components separately.

Assumptions and exclusions

Inspect deck condition after stripping and maintain temporary weather protection.

Outside the stated scope: No roof deck reconstruction, structural falls correction or interior repairs.

A wet or unsound deck changes replacement quantity and system specification. If the scope changes after a client reviews the estimate, update the relevant quantities, allowances and written exclusions before sharing a revised PDF.
