Used Seaming Machines for Sale

Seaming machines close the seams on mechanically seamed standing seam roof panels after they are installed. Electric seamers travel along the seam and fold it to a single or double lock, while hand seamers are used for starts, ends and detail areas. Roofers who install mechanically seamed systems need a seamer that matches their panel profile exactly, so these tools are frequently bought and sold alongside standing seam roll formers.

What to check on a used seamer

  • Profile match: the seamer must fit the panel profile and seam height you install. Ask exactly which profile it was used on.
  • Single or double lock: confirm what seam it forms and whether it does both in stages.
  • Rollers: worn or damaged rollers can mark paint or form an inconsistent seam.
  • Motor and switch: run it and check for smooth travel and no overheating.
  • Case and hand tools: check that hand seamers and accessories are included.

Questions about Seaming Machines

Will any seaming machine work on my standing seam panels?

No. Seamers are generally built for specific panel profiles and seam heights, and using the wrong one can damage the seam or the paint. Ask the seller exactly which panel profile and roll former the seamer was used with, and compare that to the panels you install. If in doubt, ask the panel or machine manufacturer.

Is it better to rent or buy a seaming machine?

If you install mechanically seamed roofs only now and then, renting from a panel supplier may make more sense. If you install them regularly, owning a seamer that matches your profile can save time and scheduling hassle. Compare rental costs over a year against the purchase price and upkeep.

How do I test a used electric seamer?

Run it on a short section of correctly installed panels of the right profile. The seam should be fully closed, even along the length, and free of scratches or crushed metal. The machine should track without wandering. Check the cord, switch and motor for heat, and confirm all rollers turn freely.
