What this bid was compared to

A typical total for 25 squares of TPO membrane runs $12,300 to $19,988, using Mountain / Front Range prices. This bid is $4,000.

What this bid didn't say

It didn't break out labor and material costs, so the check used typical costs for a roof this size instead of this contractor's own numbers.

What that means for this answer

This is a price and paperwork check on the figures you entered — not a roof inspection, and not a quote. It can tell you the price sits outside what this roof usually costs, or that something a bid should name is missing. It cannot tell you the roof itself is fine, and it cannot price work nobody has described.

How this was calculated

Area source: 2,500 sq ft supplied and normalized to squares.
Region benchmark: Mountain / Front Range (ZIP 80202). Mountain benchmark uses a modest labor/access premium for high-growth and winter-exposure markets.
System benchmark: TPO membrane; normalized review bands and baseline direct-cost proxy are applied before visible scope adjustments.
Cost source: benchmark-derived direct cost $11,275 from the system baseline at 25 squares because actual labor/material cost lines were not supplied.
Benchmark deltas are rounded review bands, not supplier quotes or verified peer invoices.

Total price review band -74% — Submitted total is -74% vs the Mountain / Front Range TPO membrane normalized review band.

Margin (benchmark proxy): -182%. Target 15% using benchmark cost proxy $11,275. Formula: ($4,000 bid - $11,275 cost basis) / $4,000 bid = -182% gross margin.

Margin -182% - target is 15%. Target price formula: $11,275 / (1 - 15%) = $13,265; add about $9,265 or reduce cost before release.
Tear-off is not listed; confirm recover eligibility, disposal, deck exposure, and change-order rules in writing.
Waste factor is not visible; benchmark assumes about 8% for TPO membrane.
Submitted total is -74% vs the Mountain / Front Range normalized review band; normalize component scope before judging price quality.

Worked example: what the result looks like

Example only, not a real contractor bid: $4,000 for 25 squares of TPO (Thermoplastic Polyolefin), no license number, no stated warranty, and a 50% deposit.

Verdict
