• Coordinate drainage, ponding-water limitations and treatment of rust, blisters, wet insulation and failed details.
• Use the current product data and safety data sheets together when planning storage, handling and application.

Submittal and field verification

A useful product record should allow a reviewer to trace what was specified, approved, delivered and installed. Include the following items when this product is proposed or verified.

• Use the exact product name and manufacturer identifier on the submittal; do not substitute a similar family name.
• Attach the current product data sheet and the applicable installation, safety, approval and warranty documents.
• Record selected options such as size, thickness, profile, color, finish, reinforcement and attachment method.
• Identify the tested or approved assembly and list each adjoining component needed to reproduce it.
• At delivery, compare labels and revision dates with the approved record and archive superseded files instead of overwriting them.

Selection, installation and existing-roof checks

Confirm the exact product name, generation and configuration before using any value on this page. Check the roof substrate, slope, attachment or adhesive, reinforcement, edge and penetration details, accessories, tested assembly and local approval that apply to the project. For an existing roof, compare labels, package records, original submittals and physical dimensions; appearance alone is not enough to identify a product.
