Metal Roofing Snap LockWhat’s the 1 3/4″ snap-lock roof system?  It’s a system that is one of the most popular roofs that IronClad sells.  This metal panel system provides detailed, clean transitions from seam to seam which are continuous from ridge to eave.  We love how the 1 3/4″ Snap Lock provides architectural beauty and versatility while increasing the span and uplift capabilities of metal roofing systems.  IronClad Exteriors has had many customers in Park City and Salt Lake City who love the results of the 1 3/4″ Snap Lock.
