Cannot modify once installed without risking structural integrity.Limited attic space with most truss designs.Requires freight truck delivery and a crane to set in place.May require interior load-bearing walls.Larger lumber pieces and larger quantity required.Stronger than rafters higher load-bearing ratings.Cheaper than rafters requires less lumber and installation labor.
