Evidence boundary

Verify Assembly Listings Instead of Relying on Material Labels

Evaluate roof claims using current assembly listings, edge and opening details, adjacent materials and qualified review.

Decision file

Build a clearer project record

01

Separate material from assembly

A metal panel label does not establish the performance of the complete roof. Record deck, underlayment, coverings, gaps, edges and attachments.

02

Request current listings

Ask for the exact tested or listed assembly, product identifiers, limitations and installation conditions that match the proposal.

03

Review edges and openings

Document eaves, soffits, vents, ridges, walls, valleys and penetrations where gaps or debris can affect the assembly.

04

Include adjacent components

Record gutters, rooftop equipment, decks, fences, vegetation and stored materials as project context without promising risk reduction.

05

Plan debris maintenance

Ask how accessible roof, gutter and valley areas are inspected and maintained; do not use maintenance-free language.

06

Route code and fire questions

Use current authority information and qualified review for actual performance and applicability. No page here certifies a fire class or outcome.

07

Separate material from assembly evidence

A metal panel description does not establish the fire classification of the complete roof. Record the deck, underlayment, insulation or cover board, fastening and tested configuration cited by the supplier, then compare that evidence with the actual proposed assembly.

  • Capture the listing identifier
  • Check scope and limitations
  • Match every layer and attachment
08

Inspect vulnerable roof interfaces

Add eaves, ridges, valleys, vents, skylights, gutters and wall junctions to the evidence checklist, along with adjacent combustible materials and debris collection points. Route risk and code conclusions through current authoritative guidance and qualified project review.

  • Do not promise wildfire outcomes
  • Record opening and edge details
  • Plan accessible maintenance
09

Maintain a current evidence file

Save the applicable code source, authority guidance, listing or evaluation document, manufacturer instructions and drawing revision with a checked date. If a product or layer changes, reopen the comparison rather than carrying forward the original assembly claim.

  • Prefer primary documents
  • Record superseded evidence
  • Require written substitution review
10

Build an assembly-claim traceability table

For every fire or wildfire-related statement, list the exact claim, current BC code or authority source, tested or assessed assembly identifier, product document, applicable limitations and proposed roof drawing. Compare all layers, attachment and edge conditions with the cited configuration; mark any mismatch unresolved. Include the checked date because listings and code editions change. Keep adjacent openings, debris zones and maintenance as separate project questions. This table supports review of evidence and must not turn a metal material label, isolated test or generic wildfire description into a certified classification or promised outcome.

  • Quote no unsupported performance class
  • Use current primary sources
  • Match every assembly layer
  • Record listing status and date
  • Recheck after any substitution
