Industrial Metal Roofing: Structural Roof Systems Built to Perform

When you’re managing an industrial building in Colorado, your roof isn’t just a cover—it’s a core part of the structure. That’s where structural metal roofing systems come in. These systems offer long-lasting performance, load-bearing strength, and reduced maintenance—making them ideal for warehouses, factories, and distribution centers across Denver, Colorado Springs, and beyond.

Here’s what you need to know.

What Is a Structural Metal Roofing System?

A structural metal roofing system is designed to act as both the roof and part of the structural framework. Unlike architectural metal roofing, which is applied over solid decking, structural systems are typically installed over open framing like steel purlins or joists.

These systems are engineered to:

• Span across open framing

• Support live loads like snow, wind, and maintenance traffic

• Resist uplift forces from severe weather

Common profiles include:

• Standing seam panels (mechanically seamed or snap-lock)

• Corrugated or trapezoidal panels

Key Benefits of Structural Metal Roof Systems

✔ Long Spans, Fewer Supports
Metal panels can span wide gaps between structural members, reducing the need for additional support framing.

✔ Weather-Resistant and Durable
With proper coatings and seaming, these systems offer exceptional protection against Colorado’s hail, snow, and UV exposure.

✔ Speed of Installation
Open framing means fewer materials and less time on site compared to decking and insulation layers.

✔ Built-In Drainage
Sloped panels direct water efficiently to gutters, reducing ponding risks.

✔ Code Compliance
Modern systems meet IBC and FM Global wind uplift and fire performance standards.

Where They're Used

Structural metal roof systems are commonly installed on:

• Warehouses and distribution centers

• Manufacturing facilities

• Large agricultural buildings

• Aviation hangars

• Storage depots

These systems are especially useful in areas with wide building footprints and low-slope designs.

What Makes It Structural?

For a roof to be considered “structural,” it must meet these criteria:

• Able to span purlin-to-purlin without continuous decking

• Withstands live loads and uplift without additional support

• Compatible with diaphragm bracing for lateral loads

Systems may be designed using:

• Open framing: Metal panels attached directly to steel purlins

• With or without insulation: Insulation may be added above or below the panel, depending on thermal performance needs

Panel Attachments and Fasteners

Panels may be:

• Mechanically seamed for maximum water resistance and wind uplift

• Clip-fastened to accommodate thermal movement

• Through-fastened for quicker installation (less common on low-slope roofs)

Proper alignment, fastener spacing, and manufacturer guidelines are critical for performance and warranty compliance.

Code Requirements in Colorado

In Colorado’s Front Range, industrial roofs must meet:

• IBC 2021 wind and snow load requirements

• Local jurisdiction permitting and fire classification

• FM approvals for insurance-backed installations

FAQs

What gauge metal is used for structural roofing?

Most structural panels are 22 or 24 gauge galvanized steel. Thicker gauges are used for longer spans and higher wind zones.

How long does a structural metal roof last?

With proper installation and maintenance, these systems can last 40–60 years. Coatings like PVDF (Kynar) help resist fading and corrosion.

Can structural metal roofing be insulated?

Yes. You can install batt insulation between purlins or use rigid insulation above the panels with thermal blocks.
