CSI MasterFormat Sheet Metal Flashing Guide: Division 07 62 00 and 07 71 00

For architects and specifiers, CSI MasterFormat provides the organizational framework for every project specification. Sheet metal flashing and trim occupies Division 07 — Thermal and Moisture Protection — specifically Sections 07 62 00 and 07 71 00. Understanding how these sections are structured, what they require, and how fabrication shop drawings satisfy them is essential to writing tight, defensible specifications that protect both the design intent and the owner's budget.

How MasterFormat Organizes Division 07

CSI MasterFormat 2016 organizes the specification universe into numbers and titles at multiple levels. Division 07 covers Thermal and Moisture Protection. Within Division 07, the relevant sections for sheet metal work are:

Most commercial projects include both 07 62 00 and 07 71 00: the former for custom field-fabricated trim, the latter for proprietary engineered systems. Understanding where a given trim piece falls determines which submittal path applies and which quality standard governs.

Section 07 62 00 — Sheet Metal Flashing and Trim: What to Include

A well-written Section 07 62 00 covers four areas: general requirements, submittals, products, and execution. Here is what each area should address:

Part 1 — General

Specify:

• Reference standards (SMACNA Architectural Sheet Metal Manual, 7th Edition; ASTM material standards)
• Installer qualifications — typically "Minimum 5 years' experience in fabrication and installation of architectural sheet metal trim"
• Mockup requirements for exposed trim if applicable
• Storage and handling requirements (no storage in contact with concrete or masonry)

Part 2 — Products

The products section should specify material, gauge, coating, and fabrication method. Typical language:

Part 3 — Execution

Execution language should address installation method, lap requirements, and sealant application. Reference SMACNA details by figure number where applicable (e.g., "Install coping caps in accordance with SMACNA Architectural Sheet Metal Manual, Chapter 4, Detail 4-1E for clip-fastened coping").

Section 07 71 00 — Roof Specialties

Section 07 71 00 applies when the coping cap system is proprietary — engineered with a specific clip system, tested to ANSI/SPRI ES-1 or FM Global wind uplift standards, and supplied with a manufacturer's warranty. The submittal path for 07 71 00 includes:

• Product data from the manufacturer (installation instructions, wind uplift test reports)
• ANSI/SPRI ES-1 or FM 1-90 test documentation where wind uplift is specified
• Color samples and finish specification
• Installer certification if a manufacturer's warranty is required

Submittal Requirements Under 07 62 00

Division 07 62 00 submittals typically include:

1. Shop Drawings: Cross-section profiles of each custom trim type, with all leg dimensions, bend angles, material, gauge, and coating labeled. Profiles must be drawn to scale or with dimensions sufficient to verify compliance with the specification.
2. Material Certifications: Mill certificates for Galvalume or aluminum coil, confirming ASTM compliance and coating weight.
3. PVDF/Kynar Certification: For Kynar-coated items, the coating applicator's certification that the coating contains ≥70% PVDF resin and meets AAMA 2605.
4. Color Samples: For Kynar-coated trim, physical color chips submitted for architect's review and approval before fabrication.
5. Installer Qualifications: If specified, a letter from the sheet metal contractor documenting relevant commercial project experience.

How Trimgy Drawings Satisfy 07 62 00 Submittals

When a contractor uses Trimgy to draw the coping cap or flashing profile, the output is a scaled cross-section showing every leg dimension, material, gauge, and coating. This drawing contains exactly the information required for Item 1 above — the shop drawing submittal. The contractor exports the Trimgy cross-section, adds their company title block, and submits it through the standard RFI/submittal process.

This is architecturally significant: the profile drawn in Trimgy is the profile that gets fabricated. There is no intermediate step where a verbal description or freehand sketch gets re-interpreted by the shop. The dimensional intent is locked at the drawing stage.

For material certifications and coating certifications (Items 2–3), the fabricating shop supplies those documents. Trimgy's role is the profile shop drawing.

Reference Standards in 07 62 00 Specs

A well-written Division 07 spec references these standards explicitly in Part 1:

• SMACNA: Sheet Metal and Air Conditioning Contractors' National Association. Architectural Sheet Metal Manual, 7th Edition. The primary technical reference for gauges, hem details, seam types, and installation practice.
• ASTM A792: Steel Sheet, 55% Aluminum-Zinc Alloy-Coated by the Hot-Dip Process (Galvalume).
• ASTM B209: Aluminum and Aluminum-Alloy Sheet and Plate.
• AAMA 2605: Voluntary Specification, Performance Requirements and Test Procedures for Superior Performing Organic Coatings on Aluminum Extrusions and Panels. Referenced for PVDF coating requirements.
• ANSI/SPRI ES-1: Wind Design Standard for Edge Systems Used with Low Slope Roofing Systems. Referenced when wind uplift testing is required for coping.

Specification Writing Checklist for 07 62 00

Before issuing a Division 07 62 00 section for bid, verify that the spec:

• Specifies material by ASTM designation, not just trade name
• Sets minimum gauge or thickness by trim type (not a single blanket gauge)
• References SMACNA minimum gauges as a floor, not just a suggestion
• Requires PVDF certification if Kynar coating is specified
• Identifies which items require shop drawings and which require material certs
• Specifies the SMACNA detail number or equivalent for installation of coping, sidewall flashing, counter flashing
• Includes a sealant compatibility note (not all sealants are compatible with Galvalume or PVDF coatings)
