Standing Seam Metal Roofs Explained

Are you getting what you really want?

When a building owner chooses a metal roof, they should expect it to last the life of the building.
Unfortunately, there are metal roof options out there that are sure to disappoint over time. 
Here at Ledegar, we want you to be educated before making your investment.

Standing Seam Metal roofs vs. “Exposed Fastener” metal roofs

Standing-Seam-metal-roof.jpgOften, when a consumer researches standing seam, they actually end up with what is called exposed fastener or screw-through metal roofs. They are not the same as standing seam roofs. 

A standing seam roof has hidden fasteners and is designed to allow for the metal’s natural expansion and contraction during thermal changes.  A Ledegar standing  seam metal roof is custom fit on the job site from continuous panels.  This system leaves no areas for future water infiltration.

The exposed-fastener metal roof panels have the appearance of barn roofs because they have traditionally been used for agricultural purposes.  These panels are often produced from lower quality metals and have lower quality finishes. Unfortunately they are making their way into residential uses as consumers are looking for the “cheaper” options and contractors who aren’t skilled in standing seam metal installations try to get a piece of the metal roofing market.

Do you really want barn panels protecting everything you own?

Often, when recommending this inferior system, a contractor may suggest that they can install them directly over a shingle roof to “save you money”.  There are two huge problems with this concept that will cost you more in the long run.

  1. While the roof contracts with temperature changes, the asphalt shingles will be rubbing constantly on the back of these metal panels, eventually wearing through and needing to be replaced.
  2. Without proper tear off, the decking cannot be inspected for rotting and a lifetime underlayment cannot be installed.  Your original leaking roof will still be a leaking roof.
