--- title: Top Metal Roofing + Siding Systems Explained description: From ag to commercial to industrial to standing seam, learn about the four most commonly used metal panel systems today. --- [HY-C Blog ](https://www.hy-c.com/blog) # [Top Metal Roofing + Siding Systems Explained](https://www.hy-c.com/blog/top-metal-roofing-siding-systems-explained) Written by [Kyla Pehr](https://www.hy-c.com/blog/author/kyla-pehr) | Mar 6, 2026 3:30:00 PM [Pest-Blok™ by HY-GUARD EXCLUSION®](https://www.hy-c.com/blog/introducing-pest-blok-by-hy-guard-exclusion), created in conjunction with [Pest-Blok inventor Will Langman](https://pestblok.com/), is a new product line made to block pests from entering metal roofs, metal siding, and vinyl siding corners. Launching in Spring 2026, the [Corrugated Exclusion Strip™](https://www.hy-c.com/hy-guard-exclusion-pest-blok-corrugated-exclusion-strip) **covers almost three feet** at a time, removing the need to install small inserts between every rib. It seals the open gaps in metal roof panels **at the ridge** and **along the bottom edges**. **Four** distinct strip profiles are available, engineered for each common metal panel type: - Agricultural panels - Commercial panels - Industrial panels - Standing seam panels And each strip profile comes in two versions: - **Ridge (roof peak)** - **Lower edge (eave, drip edge, bottom panel)** But what makes these panel systems different? And how do you know [which one you’re working with](https://joehayman1-droid.github.io/PestBlokTool/)? ## What are agricultural panels? [Agricultural panels](https://joehayman1-droid.github.io/PestBlokTool/) (often referred to as ag panels) are versatile, durable, and cost-effective metal roofing and siding systems with visible screws. **Key identifiers *****(dimensions may vary)*** - 9" center-to-center rib spacing - ¾” rib height - 36" coverage - 29 gauge to 26 gauge steel - Exposed fasteners - Typical minimum 3:12 roof slope **Common uses** - Pole barns - Livestock buildings - Equipment storage - Detached garages **Why you’re likely to encounter this panel system** - Most affordable metal option - Fast, simple installation - Strong weather resistance - Widely available and easy to replace **Why this matters for pest and wildlife pros: **Ag panels have larger, more irregular gaps — prime entry points for birds, bats, rodents, and insects. ## What are commercial metal panels? [Commercial panels](https://joehayman1-droid.github.io/PestBlokTool/) balance performance, appearance, and energy efficiency. They’re used where aesthetics and code compliance matter. **Key identifiers *****(dimensions may vary)*** - ~6” center-to-center rib spacing - ~¾” rib height - 36" coverage - 26 gauge to 22 gauge steel - Exposed or concealed fasteners - Typical minimum ¼:12 roof slope **Common uses** - Retail centers - Office buildings - Schools - Warehouses **Why this panel system is commonly used** - Energy efficient - Long-lasting - Clean, professional appearance - Designed for code compliance **Why this matters for pest and wildlife pros: **Tighter profiles still leave consistent gaps along ridges and eaves where nesting birds and insects enter. ## What are industrial metal panels? [Industrial panels](https://joehayman1-droid.github.io/PestBlokTool/) are thicker, stronger systems built for large facilities and harsh conditions. **Key identifiers *****(dimensions may vary)*** - 12” center-to-center rib spacing - 1¼” rib height - 36" coverage width - 29 gauge to 22 gauge steel - Exposed or concealed fasteners - Typical minimum ¼:12 roof slope **Common uses** - Factories - Manufacturing plants - Cold storage - Distribution centers **Why this profile shows up on large facilities** - Built for harsh environments - Strong impact resistance - High thermal performance - Long service life in tough conditions **Why this matters for pest and wildlife pros:** Larger ribs create deeper voids, which are ideal for birds, starlings, pigeons, and larger rodents to get inside. ## What are standing seam panels? [Standing seam panels](https://joehayman1-droid.github.io/PestBlokTool/) are a premium roofing system with raised vertical seams and concealed fasteners for maximum water protection. **Key identifiers *****(dimensions may vary)*** - 16" seam spacing - 1” and ¾” seam heights - 16" coverage width - 26 gauge to 24 gauge steel - Hidden fasteners - Typical minimum ½:12 roof slope **Common uses** - Custom homes - Commercial buildings - Architectural wall accents **Why does a homeowner choose standing seam panels?** - Superior leak protection - Modern, architectural appearance - Minimal fastener maintenance - Long lifespan **Why this matters for pest and wildlife pros: **Standing seam roofs have fewer fastener penetrations but still leave consistent ridge and edge gaps pests exploit. ## Four types, one solution Every metal panel system has both a different profile and different gaps that pests can exploit. The [Corrugated Exclusion Strip](https://www.hy-c.com/hy-guard-exclusion-pest-blok-corrugated-exclusion-strip) from the Pest-Blok by HY-GUARD EXCLUSION line is designed to match each system precisely, whether you're working with agricultural, commercial, industrial, or standing seam panels. [With the right profile](https://joehayman1-droid.github.io/PestBlokTool/) at the ridge or lower edge, you can: - Seal openings faster - Protect the structure long-term - Eliminate tedious rib-by-rib inserts **One strip. Fewer steps. Stronger protection.** [View full post](https://www.hy-c.com/blog/top-metal-roofing-siding-systems-explained) ```json { "@context" : "http://schema.org", "@type" : "BlogPosting", "author" : { "@type" : "Person", "name" : "Kyla Pehr" }, "dateModified" : "2026-03-06T15:30:00.701Z", "datePublished" : "2026-03-06T15:30:00Z", "headline" : "Top Metal Roofing + Siding Systems Explained", "image" : { "@type" : "ImageObject", "height" : 418, "url" : "https://5842867.fs1.hubspotusercontent-na1.net/hubfs/5842867/Kyla%20Blog%20Media/Screenshot%202026-03-06%20at%208.39.56%20AM.png", "width" : 834 }, "mainEntityOfPage" : "https://www.hy-c.com/blog/top-metal-roofing-siding-systems-explained", "publisher" : { "@type" : "Organization", "logo" : { "@type" : "ImageObject", "height" : 60.0, "url" : "https://www.hy-c.com/hubfs/Logos/HY-C%C2%AE/HYC.logo.rgb_10.23.jpg", "width" : 94.27609 }, "name" : "HY-C Blog" } } ```
