Also known as valley trusses and valley sets. Above is a sketch of how nailplate trusses handle the creation of valleys in a "T: shaped roof. The process is similar to building a scotch valley in standard framing. Also look at the explanation for a girder truss. Looking up through the inside of a roof in construction. The trusses can be seen sat on and clipped to the top chords of the trusses under them. A point to note is the fact that these particular trusses are very simple with just vertical webs. There is not the same need for the angled webs as the trusses are well supported along their bottom chords.
