⚠️ Scope Risk Alert

Top 5 Proposal Red Flags to Catch Before Signing

The most expensive contractor mistakes happen in the fine print. Inspect your written bid for these common omissions:

1. Unspecified Decking Replacement Rate

If hidden wood rot is found during tear-off, an open-ended clause allows the contractor to charge $150+ per sheet. Demand a fixed rate ($75–$110/sheet installed) in writing.

HIGH SURPRISE-BILL RISK

2. Reusing Old Chimney & Valley Flashing

80% of post-roofing leaks happen at wall transitions. If the quote says "flash as needed" instead of detailing new step and counter flashing, you risk premature failure.

WATERPROOFING COMPROMISE

3. HVAC Sizing by Floor Area Guesswork

Sizing by "500 sq ft per ton" rule-of-thumb leads to oversized equipment that short-cycles, fails to dehumidify, and drives up electric bills. Insist on Manual J load sizing.

ENERGY & HUMIDITY HAZARD

4. Unmatched Indoor & Outdoor HVAC Coils

Pairing a new 16 SEER2 outdoor condenser with an old existing indoor evaporator coil voids the manufacturer AHRI certificate, drops efficiency, and cancels factory warranties.

WARRANTY & SEER2 LOSS

5. Demanding Over 33% Upfront Deposit

Standard industry payment terms are 10%–33% down, 33% upon delivery/tear-off, and final balance after final municipal permit inspection and lien waiver signoff.
