While in the attic, be sure to inspect the roof framing. Check the rafters and trusses for cracked, broken, and sagging sections. Are the rafters spreading apart near the ridge? Although these problems are uncommon, they indicate a structural defect that should be evaluated by a professional. Look at the floor joists. If they’ve been cut to accommodate an opening for an attic fan or pull-down stairs, have the cut ends been properly secured to a header? They should be. If not, record that fact on your worksheet for future correction.
When trusses have been used for roof framing, check to see if any of the webs or chords have been removed. Homeowners have been known to cut and remove them to accommodate storage items. This affects the structural integrity of the truss and should also be recorded on your worksheet for needed repairs.
