Will My Roof Fall Down?

DannyWhitty's picture

Hey all,

 I'm installing a ceiling cassette heat pump in my attic and there are two 2x4 that are in the way.  I can't tell if it's a structural truss or if it was temporary truss put in place during installing (and currently serves no purpose).  It runs from gable wall to gable and I would need to cut 16" off the chord end which would essentially remove connectivity between the load-bearing walls.  I was wondering if you fine people would be willing to take a look at the pictures below and let me know if making this cut is a bad idea.

 

Here's a picture of the attic 

 

Here's a rough sketchup of what's going on in my attic:

Here's a picture of an old set of plans I found that make no mention of a truss in the attic.

 

 

I appreciate any help/knowledge you all are willing to share.

It looks to me like what you (post #216022, reply #1 of 2)

It looks to me like what you are referring to is a "strong back".  Appears to be a stick framed roof and the strong back maintains the spacing between the ceiling joists.  Typically once the drywall is installed on the ceiling below, the strongback isn't absolutly necessary.  I hesitate to recomend removing it though without physically examining you specific situation.  Perhaps you could "header off' what you want to remove and thereby continuing any lateral load.
