Weathertight Seams

Protect against leaks.

The MR-24^® roof system is the only standing-seam roof system where the critical final 180 degrees of the roof panel seam is mechanically field-rolled to complete a 360-degree Pittsburgh double-lock seam—creating the tightest seam available today. Inside the seam, a factory-applied sealant assures weathertightness in even the most unforgiving conditions.
