The conversion from a trussed roof to a trussless roof simply involves the redistribution of the roofs weight from the trusses to beams running from gable to gable. The sad fact is your builder could have installed attic trusses over this garage for just slightly more than what the existing trusses cost.

The usual way in which trussed loft conversions are carried out is to install steel joists across the width of the roof and running the full length of the roof.
