The delivered shingles differ from your proposal: what should you verify?
Check product identity and written substitutions before materials are installed, using packaging photographs and the accepted proposal.
By Dallas Texas Roofing Services · Homeowner planning resources
Quick answer: Compare the delivered product name, line, color and relevant identifiers with the signed scope. If they differ, ask the provider to explain and document any proposed substitution before the material is incorporated into the roof.

Compare identifiers, not just color names
A roofing proposal should identify the intended product closely enough to distinguish it from another line by the same manufacturer. From a safe ground-level location, ask for packaging photographs that show the manufacturer, product line and color. Do not enter a loading area or move bundles to obtain the information.
Compare those identifiers with the accepted proposal and any later written changes. Similar packaging or a familiar color name does not establish that two products are identical. If information is missing, request the current product literature and an explanation of what is being delivered.
Ask what a substitution changes
A proposed substitute can raise questions about appearance, assembly compatibility, installation instructions or warranty eligibility. Ask the provider to explain those consequences using the actual product documents. Do not assume a different item is automatically better or worse based solely on a sales description.
The GAF installation instructions linked here are an example of product-specific requirements, not approval for whatever arrives at your house. A different product requires its own applicable instructions. If accessories also change, include them in the written comparison rather than focusing only on the field shingles.
Resolve the discrepancy in the project record
Ask the responsible project contact to confirm whether the delivery is correct, a mistake or a proposed substitution. Record the date, product identifiers and response. Follow the contract’s written change process before agreeing to a different scope; do not rely on an undocumented conversation with a delivery driver.
At closeout, retain the final product list and available packaging or installation photographs with the invoice and warranty documents. They help answer later questions about what was installed. The FTC’s contractor guidance supports obtaining clear written terms; this checklist does not determine anyone’s legal rights under a particular contract.

Frequently asked questions
Can the roofer substitute an equivalent product?
Check the contract and the proposed written change. Ask what “equivalent” means for the actual assembly, appearance and warranty rather than accepting the label alone.
What records should I keep from the delivery?
Retain safe label photographs, the final product list and any approved substitution. Ask the provider to reconcile them with the installed assembly at closeout.
