Choosing between standing seam and screw-down (exposed fastener) metal panels is one of the biggest decisions you'll make for your new metal roof. Both styles are durable and built to last, but they look different, cost different, and perform differently over time. Here's how to pick the right one for your Middle Tennessee home.
What Is Standing Seam?
Standing seam panels are interlocking metal sheets with raised vertical seams that run from the ridge down to the eave. The fasteners are completely - clipped underneath the panels - so nothing penetrates the metal surface. This is the modern, premium look you see on high-end homes and commercial buildings.
What Are Screw-Down Panels?
Screw-down panels (also called exposed fastener or R-panel) are attached with screws driven directly through the metal into the roof deck. The screws have rubber washers to seal out water. This is the classic look you see on barns, workshops, and many traditional Tennessee homes.
Cost Comparison
• Screw-down: Typically $4-$7 per square foot installed - the most affordable metal roofing option.
• Standing seam: Typically $8-$14 per square foot installed - about double the cost of screw-down.
The price difference reflects more material, more labor, and more sophisticated forming and clipping systems.
Lifespan and Maintenance
Both styles can last 40+ years, but there's an important difference. The rubber washers on screw-down panels eventually dry out, crack, and need replacement - typically every 15-20 years. Standing seam has no exposed fasteners to fail, so it's essentially maintenance-free for the life of the roof.
Which Looks Better?
This is personal preference, but standing seam has clean, vertical lines that work beautifully on modern, farmhouse, and traditional homes. Screw-down has visible ribs and screw heads, giving a more rustic, agricultural feel that's perfect for cabins, barns, and country properties.
Our Recommendation
If budget is the priority and you don't mind re-screwing the roof in 15-20 years, screw-down is a great value. If you want a true install-and-forget roof with the cleanest possible look, standing seam is worth the investment.
