Complete Scope of Work

Copy or customize these verbatim specifications into your contractor proposal.

1

1. Tear-Off & Substrate Preparation

Preparation for metal roof installation.

  • Complete removal of existing shingle layers and fasteners.
  • Inspect wood substrate; ensure smooth deck surface to prevent telegraphing through metal panels.
  • Install continuous high-temperature self-adhered underlayment across entire roof deck.
2

2. Panel Fabrication & Concealed Clip Fastening

Installation of standing seam panels.

  • Install 24-gauge Galvalume standing seam metal panels with 1.5-inch or 2-inch vertical seams.
  • Secure panels using concealed stainless steel expansion clips to allow thermal expansion and contraction.
  • No exposed fasteners on the panel field; mechanical or snap-lock seaming per engineering specs.
3

3. Custom Flashing, Trim & Penetrations

Perimeter trim, valleys, and pipe flashings.

  • Install custom-bent drip edge, rake trim, sidewall flashing, and vented ridge metal with insect screening.
  • Fabricate open hemmed valley details with concealed valley cleats.
  • Flash plumbing pipes with high-temp retro-fit silicone boots and stainless steel clamps.

4. Cleanup, Inspection & Warranties

Debris removal, magnet sweep, and manufacturer warranty.

  • Magnetically sweep entire property perimeter for screws and clips.
  • 30-Year Kynar 500 / Hylar 5000 finish warranty against fading and chalking.
  • 5-Year contractor leak-free workmanship warranty.

Scope-Gap Protections: 3 Clauses to Include

These contractual gotchas account for 85% of change-order arguments on standing seam metal roof proposal templates.

Telegraphing Substrate Imperfections

The Risk: Standing seam panels reflect deck ridges or uneven boards ('oil canning').

Protective Clause: Clause notes that minor oil canning is an inherent characteristic of light-gauge architectural metal and does not indicate structural failure.

Standard Underlayment Breakdown under Metal

The Risk: Standard organic or cheap synthetic underlayment melts or deteriorates under hot metal panels.

Protective Clause: Guarantees 100% full-deck coverage of high-temperature self-adhering underlayment rated to 250°F+.

Exposed Fastener Wear

The Risk: Customer expects standing seam but other quotes propose cheap exposed-fastener corrugated metal.

Protective Clause: Highlights the 100% concealed clip system, explaining why exposed screw gaskets fail after 8–10 years.

Frequently Asked Questions

Why is 24-gauge steel preferred over 26-gauge or 29-gauge for standing seam?▾

24-gauge steel offers superior structural rigidity, significantly reduced oil-canning risk, and the highest resistance to large hail impact compared to lighter builder-grade metals.

How long does a standing seam metal roof last?▾

A properly installed 24-gauge Galvalume roof with Kynar 500 coating lasts 50+ years, outlasting 2 to 3 asphalt shingle roof lifecycles.
