Newer truss framed roofs are made with prefabricated trusses.

When measuring in your attic make sure you are only putting your body weight on the trusses. The structure should be sufficiently wide to allow for a loft and attic spaces the loft area must be on a living floor and have attic rooms on both sides separated by knee walls a flat ceiling in the loft area and a floor below steep enough roof pitch to provide appropriate ceiling height for the loft area. The sad fact is your builder could have installed attic trusses over this garage for just slightly more than what the existing trusses cost. Most codes require a specified minimum amount of headroom and it s tough to meet this requirement when insulating a finished attic especially since most codes require insulation equal to r 38 or more.

Trusses are like big structural triangles that have angled top pieces that serve as rafters horizontal pieces that serve as floor joists and interconnecting web pieces that give the triangle strength.
