ATTIC area inspection usually allows further evaluation of the roof system to include the frame members and the decking. Both water intrusion and frame/decking damage will more likely be noticed during internal attic inspection than outside roof inspection. The presence or absence of insulation between conditioned/unconditioned spaces needs to be noted. Attic/roof ventilation also will be determined. There may be both electrical checks and plumbing checks within an attic inspection depending on the individual house.
