5V Crimp vs Standing Seam
5V Crimp and standing seam are both metal roofs, but they are different products. 5V Crimp is the classic Old Florida exposed-fastener panel from $3.66/ft; standing seam is the concealed-fastener premium roof from $2.61/ft. This page compares the two so you can pick the right one.
5V Crimp — The Old Florida Look
5V Crimp is a 24"-wide panel with five small V-shaped ribs, fastened with screws through the flat between the ribs. It is the panel you see on historic Florida homes, porches and cracker houses. It is inexpensive and easy to install, but the screws are exposed.
Standing Seam — Concealed Fasteners
Standing seam panels lock at the seam and fasten with hidden clips or a folded nail strip, so no screws show on the roof. That means nothing to back out or leak, and the roof handles thermal expansion better. It costs more but lasts longer with less maintenance.
Cost Comparison
5V Crimp: from $3.66/ft (26ga Galvalume). Standing seam: from $2.61/ft (26ga Galvalume) up to $9.69/ft (.032 aluminum Kynar). Per foot, entry-level 26ga Galvalume standing seam costs about the same as or less than 5V Crimp; each 5V panel covers 24" of roof width versus 15"–18" for standing seam, and standing seam adds clips and specialized trim, so compare the whole-roof cost.
Which to Choose
Pick 5V Crimp for the traditional Florida look, a tight budget, or a porch/barn. Pick standing seam for a home you want to be low-maintenance for decades, a coastal home, or a roof with long runs. Many Florida homes use both.
