Two bids that differ by $4,000 on the same roof almost always differ because one of them is hiding something. Either the cheaper bid is missing scope (which costs you more later), or the more expensive bid is padding allowances to cover their overhead. This checklist is the line-by-line filter we use to tell which is which.
The bid should state the roof measured area in squares with the slope-by-slope breakdown.
Install new shingles is not enough. The bid should say full tear-off to decking.
Synthetic underlayment is the standard. Felt is a flag.
At a minimum: eaves, valleys, all penetrations. As a line, not lumped into flashings.
Chimney flashing, sidewall step flashing, kick-out flashing at roof-to-wall transitions.
Ridge vent + soffit intake, or box vents; how many; manufacturer assumption.
Most bidders give a per-sheet price. A flat number with no per-sheet is either generous or padded.
The City of Kennesaw / Marietta / Acworth pulls in about $250–$450 for a residential reroof.
Manufacturer warranty registered in your name, length in years, transferable.
Deposit not above 30%. Draw schedule if any. Final payment trigger listed.
That itself is information. A licensed contractor with a solid bid should be able to write a line-by-line scope. Refusal to do so is one of the strongest look elsewhere signals in the industry.
That is the bid. Sign it. We do not manufacture work — if you are already holding a fair, scoped bid, the right answer is to use it.
No. The middle bid is sometimes middle because it is hiding scope, sometimes middle because it is correctly priced. The line items tell you which.
