Chapter 4: Cross Seams in our series “Historical Preservation Details in Standing Seam”.

The cross seam is a method of connecting two panels vertically up the roof in a watertight fashion without needing to use sealant. This is a technique that only works for mechanical locking panels and is very common in historic standing seam since pans were in shorter lengths due to lack of roll-forming machinery. Getting quick and efficient at creating the cross seams takes some practice, but the detail really gives the roof a feel that matches older homes or historic properties.
