Build a record someone else can follow
Start with the manufacturer, named product, and membrane specification in the proposal. Add the described layers and attachment method. If a detail is absent, record it as requested or unknown instead of filling it from a similar product online.
| Record field | If it is missing |
|---|---|
| Manufacturer and product | Ask for the named membrane |
| Specification | Request the specification actually proposed |
| Layers and attachment | Ask for the described assembly |
| Applicable documents | Ask which records correspond to this roof |
Connect each record to the proposed roof
Ask the contractor which documents describe the assembly being offered for your building. Keep product information, proposal revisions, and relevant assembly information distinguishable. A folder full of unrelated product sheets is less useful than a short set clearly tied to the actual scope.
Record revisions rather than overwriting history
If a substitution or scope change is proposed, ask for the corresponding updated description and documents. Keep the approved revision identifiable. The checklist is a document register; it does not certify compatibility or approve a roof design.
Questions to take with you
- Record what the proposal actually says.
- Request missing identifiers.
- Keep changes tied to a dated revision.
Create a TPO document checklist for the one proposed system you are reviewing.
