When we removed the end wall at the old kitchen (area of new pantry facing kitchen) we found that the ceiling trusses did not carry the load from exterior wall to exterior wall across the home, as is usually standard in ramblers. The roof trusses were cut off and then we had to structurally engineer a beam to support roof beams spanning the home, install and bury in ceiling, from corner of old kitchen to exterior wall to support roof truss loads down to foundation.
