1” Nailstrip vs. 1.5” Nailstrip — Panel Height Makes a Difference 

Written By Alsteel Roofing Metal Roofing Supply

How Seam Height Impacts Strength and Durability 

Nailstrip panels provide the clean, architectural look of standing seam without requiring clips. Both 1” and 1.5” systems are popular, but understanding the difference helps you deliver the best results. 

1” Nailstrip 

Lightweight and easy to install, this profile is ideal for smaller roofs, accent areas, and steep slopes (≥3:12). It’s perfect for residential projects that require both speed and aesthetics. 

 

1.5” Nailstrip 

Built for performance, the taller seam offers enhanced water shedding and wind uplift resistance, making it the preferred choice for larger roofs or coastal zones where storms are common. 

Pro Insight: 

Use 1” Nailstrip for residential or decorative applications and 1.5” Nailstrip for durability and performance in high-wind regions.
