Rock Solid Design

Vertical Seam is the SUV of standing seam – cost efficient, attractive, and able to handle a variety of needs. Vertical Seam has modern 1.75″ high ribs in widths of 12″, 16″, and 18″ apart. A hidden fastening clip allows unlimited expansion and contraction, allowing for longer panels. Vertical Seam installs quickly and meets the wind demands in Florida and Miami-Dade County Hurricane Zones. Taller ribs allow Vertical Seam to be installed over open framing as well as solid decking.

Customer Reviews
133 Erich M Vertical Seam Ash Gray 001

Erich M. Maple City, Michigan

Overall, my experience was very good. You may remember we had an issue with the delivery date which you quickly rectified; everything was delivered on the date you had originally specified. The truck operator was very efficient in unloading and there was no damage. I only have one minor issue. I ordered the metal in ash gray but find in most lights, it has a distinctly tan color so there is some contrast with the gray roof and the barn. Not sure if this shows up in the pictures. In dim light, they both appear to be gray. FYI, the original barn dates to c.1910. The attached shed was constructed this past summer by myself with friends and family. Like the barn, it is constructed with traditional post & beam techniques. Should last another 100+ years! Thanks for all your help.
