Let's talk about trusses.
The house we built 10 years ago that we live in now was built using a truss company. We did not build out the second floor because we didn't think we needed it at the time. Not a true 2story house. Second floor was optional. I wanted my two little ones right next to me, not upstairs since we had just had a fire. The trusses were very expensive on a complex roofline. Lots of lumber.
Now we are building a house with a master down and bedrooms up.
Please tell me why some builders use trusses, some don't, the advantages and disadvantages of using a truss company.
