Standing Seam vs. Exposed Fastener Roofing: Which Is Right for You? | IPS Metal
Share
When it comes to metal roofing, two popular systems dominate the market — standing seam and exposed fastener (often called “screw-down” or “through-fastened”) roofing. Both offer excellent durability, weather resistance, and long-term value — but they differ significantly in style, cost, and ideal application.
If you’re planning a new build or upgrading an existing roof, here’s how to decide which one is right for you.
🏗️ 1. Understanding the Two Styles
Standing Seam Roofing
Standing seam roofing features tall, vertical ribs (or “seams”) that run continuously from the ridge of the roof down to the eaves. The key detail is that fasteners are concealed beneath interlocking panels, which gives the roof a sleek, modern look and excellent protection from the elements.
Each panel locks or snaps together, and clips or hidden fasteners secure them to the roof deck — meaning no exposed screws, no visible penetrations, and minimal risk of water leaks.
Best for:
-> Modern homes and architectural projects
-> Commercial and institutional buildings
-> Low- to steep-slope roofs (minimum 3:12)
Exposed Fastener Roofing
Exposed fastener systems use overlapping panels secured directly to the roof deck with visible screws and rubber washers. This is a more traditional method, often used on barns, workshops, and other agricultural or industrial structures.
While less sleek than standing seam, exposed fastener roofing offers proven performance at a much lower upfront cost. The visible fasteners are part of the design and can be color-matched to the panels for a clean finish.
Best for:
-> Agricultural and storage buildings
-> Workshops and garages
-> Residential projects on a budget
-> Steeper roofs (4:12 or higher)
💰 2. Cost Comparison
| Feature | Standing Seam | Exposed Fastener |
|---|---|---|
| Material Cost | $$$ – typically 50–100% higher | $ – most economical option |
| Installation | Requires specialized tools and training | Easier and faster installation |
| Maintenance | Minimal – hidden fasteners protect from weather | Moderate – screws may loosen or washers degrade over time |
| Lifespan | 40–60 years with little maintenance | 20–30 years (longer if maintained properly) |
In short:
Standing seam roofs cost more up front but deliver longer lifespan, less maintenance, and a premium aesthetic. Exposed fastener roofs are more cost-effective, simpler to install, and ideal when budget or practicality takes priority.
🧱 3. Applications and Performance
Standing Seam: Performance & Flexibility
Standing seam systems shine in demanding environments — such as Ontario’s harsh winters — because their hidden fasteners prevent moisture infiltration and expansion stress. The floating design allows panels to move slightly with temperature changes, reducing the risk of warping or cracking.
They’re also an excellent choice if you plan to install solar panels or snow guards, since the seams provide easy attachment points without drilling into the panels.
Exposed Fastener: Practical & Proven
Exposed fastener panels are the workhorse of the metal roofing world. They’re quick to install, durable, and available in a wide range of colors and profiles. While they require periodic inspection (to tighten or replace screws), they still outperform most traditional asphalt shingles in lifespan and weather resistance — especially for garages, sheds, and light commercial structures.
🏁 4. Choosing the Right Roof for Your Project
Here’s a simple guide:
Choose Standing Seam if you want:
✅ Sleek, modern appearance
✅ Long-term performance with minimal maintenance
✅ Hidden fasteners and weather-tight protection
✅ Ideal pairing with solar panels or snow guards
Choose Exposed Fastener if you want:
✅ Budget-friendly installation
✅ Classic metal roof look
✅ Straightforward DIY or contractor install
✅ Excellent performance for non-heated or utility buildings
